INTRODUCTION
Who We Are: The Colorado Department of Education’s school-based SWAAAC (Statewide Assistive
Technology, Augmentative and Alternative Communication) teams provide multidisciplinary assistive
technology services in school districts around the state to enable students with disabilities to have equal
access to the curriculum and full participation in their education and classroom. The Boulder Valley
School District’s SWAAAC team is known as the “Assistive Technology Team” (or AT Team) and consists
of an occupational therapist, a special education teacher, and a speech/language pathologist, all with
special training in the use of assistive technology and communication systems/devices. The goal of the
AT Team is to provide resources and the student/staff training necessary so that students with
disabilities can participate in appropriate educational experiences and communicate what they know.
AAC: “Augmentative or Alternative Communication (AAC) is any device, system, or method that improves
the ability of a child with a communication impairment to communicate effectively.”
Our BVSD Assistive Technology Team has been working with students with complex
communication needs (and their school teams and families) since the team was formed in 1993, and we
have gradually organized and systematized our approach and procedures. This book is meant to be a
short yet practical introductory guide for school-based service providers and it follows a natural
progression from background material on communication and AAC systems (the tools) through brief
descriptions of the specific implementation procedures and strategies we have found useful, and finally,
several Appendices containing an assortment of pertinent charts, lists, data sheets, and handouts.
Readers seeking additional information and/or details may find the resources listed in the Bibliography
to be valuable for an initial search of the literature.
Our team approach to working with AAC is based on a generalist and a “multimodal” approach
to communication—encouraging and enhancing any and ALL signs of communicative intent and actual
communicative acts. We do not favor a limited “either/or” approach (i.e., one solution fits all students
or all situations); rather, we embrace a “both/and” vision. There are MANY possible “tools in the AAC
toolbox,” and the specific tool that may be most effective in one situation, may not work at all in
another. Strategies also need to be changed, adjusted, nuanced--we have found that FLEXIBILITY and
keeping an open mind are absolutely crucial! In addition, utilizing strategies generated from solid
research and evidence-based practice (rather than anecdotal guesswork) is paramount.
Students become a part of our Assistive Technology Team caseload by being referred by the
school team or family who might be wondering whether any type of technology exists that would be of
some benefit to their student. Alternatively, they may have heard of some type of technology that they
feel might be an excellent “fit.” In either of these cases, we arrange for our AT Team to visit the school
and carry out an AAC Evaluation (this is described in detail in our book BVSD Assistive Technology
Communication Evaluation). An AAC Evaluation can provide crucial information about the student’s
abilities and challenges and furnish quantitative data and a solid evidence-based rationale for various
assistive technology strategies to try--an excellent place to begin! Once the student becomes part of our
AT Team caseload, s/he will be followed from grade to grade and school to school until s/he graduates
from the system or else s/he no longer needs our services.

BACKGROUND
“If my possessions were taken from me with one exception, I would choose to keep the power of
communication, for by it, I would soon regain all the rest.” (Daniel Webster)
Communication may be defined as “the process of exchanging information and ideas. An active
process, it involves encoding, transmitting, and decoding intended messages.”1
Language is a code in
which we make specific symbols stand for something else. These symbols and the code are arbitrary
and must be learned: there is no objective reason why the word “house” (or the specific sounds that
comprise the word) should signify “a building in which people, especially members of a family, reside.”
The only requirement for a language is that the code is agreed-upon (and conventionalized) by members
of the same community or language group. Speech is the actual behavior of producing this code by
uttering the vocal sound patterns appropriate for the particular language. Receptive language refers to
decoding the messages (language comprehension) that are being imparted, whereas expressive
language refers to encoding and formulating the messages to a communication partner.
Speech and language are important for communication, but they are only a part of
communication. Speech prosody (the “music” of speech) is also crucial for expression: an utterance
may be delivered in a monotone, or carefully modulated in terms of intonation, stress, rate of delivery,
and pause/hesitation. This aspect of communication is termed “paralinguistic.” Also important is non-
linguistic communication which includes things like gestures, posture, facial expression, eye gaze, and
proxemics (physical distance between communicators). Metalinguistic communication pertains to
talking about language, analyzing it, judging it for acceptability within the social context, monitoring it
for errors, etc.
Learning Communication Skills
In typically developing children the process of language acquisition is usually smooth and
seamless and different “stages” are barely noticeable and seem to come and go quickly. For individuals
with more complex communication needs, stages may develop slowly, intermittently, and in an
idiosyncratic fashion.
There are a number of developmental schemas for language acquisition, and these schemas
vary in their details slightly from case to case; some overlap, some emphasize one skill over another,
some are sequenced somewhat unevenly and to compare them or to reconcile them with each other is
really “splitting hairs.” The model that our BVSD Assistive Technology Team has found most useful and
practical for the students we work with is based on three levels of communicative ability. (We have
collapsed and blended several of the levels of the schema used by Charity Rowland and Philip
Schweigert).2
Our basic paradigm is that the individual progresses in some fashion from: pre-intentional
and pre-symbolic communication through using symbols one at a time, and later, using multiple symbols
with specific ordering (syntax).

This discussion is based on Owens, p. 40-41, and Reed, Chapter 1.

This schema is outlined (and compared with ours) in Appendix A.

Three Levels of Communicative Abilities
We believe that it is important to address our students’ needs at the appropriate level: not too
high or too low (i.e., Vygotsky’s “zone of proximal development” or ZPD). Too low would bore them and
too high would bewilder them—either way it is dis-empowering and does not encourage students to
communicate their unique vision of the world. In order to address this issue, and to more effectively
serve our student population, we have found it useful to group our students according to the three
generalized communicative profiles alluded to above: emerging communicators, beginning symbolic
communicators, and intermediate symbolic communicators. Please keep in mind that these profiles
are only approximate: many times students display “splinter skills,” or appear to be functioning at a
transitional stage between two different levels.
Level 1--Emerging Communicators These are pre-symbolic communicators who may display
reflexive/reactive behavior (laughing, crying) which is interpreted by the observer as communicative,
and this level extends on through individuals who exhibit intentional goal-directed behavior (not
necessarily directed towards another person), and finally on through those who exhibit intentional
communicative behavior (goal directed behavior directed towards another individual) using gesture or
natural non-symbolic means.
Level 2--Beginning Symbolic Communicators might be using some symbols: manual sign or sign
approximations, vocalizations, stylized gestures (including pointing), and verbalizations or verbal
approximations (one through approximately 503
). They use the symbols one at a time and have not
started combining them together much, if at all. They might use (or have tried) picture or object-based
communications strategies, or a single or double-message speech generating device to indicate a simple
greeting, the desire for reinstatement of a preferred activity or a choice between two activities.
Level 3--Intermediate Symbolic Communicators may be using a number of (about 25 or more)
symbols: manual signs or sign approximations, vocalizations, verbalizations (or verbal approximations)
one at a time—they may be combining the symbols (which would imply having close to 50 symbols in
their repertoire) at least in a rudimentary syntax or word order, e.g., I want.... I like... I don’t like... I
go... etc.
Augmentative and Alternative Communication (AAC)
For students with complex communication needs (i.e., individuals who do not proceed smoothly
along through the levels of communicative competence in a timely manner), speech-language therapy
might be appropriate, as well as some form of assistive technology accommodation: “Augmentative and
Alternative Communication” (AAC) can be defined as any device, system, or method that improves the
ability of a child with a communication impairment to communicate effectively. It can include
sophisticated devices and systems (sign language, communication boards, or speech-generating devices)
as well as less sophisticated means (pictures or objects used as symbols, etc.) AAC is introduced when
the student does not develop communication in the typical fashion, or experiences significant delays,
3
Research indicates that children begin to combine words after acquiring approximately 50 words in their
repertoire. See for example Bates, Thal, Finlay, & Clancy, 2003.

6
and is used to AUGMENT (add to) whatever communication the student possesses, as part of a “multi-
modal” system. Typical indicators for introducing some form of AAC might include (but are not limited
to): a moderate to severe expressive speech/language disorder, an expressive/receptive language gap
(the student understands more than s/he can say), limited speech or expressive language improvement
with therapy, and/or the student’s frustration at his/her inability to communicate messages effectively.
Learning to use AAC strategies can be deceptively difficult! Consider: a student presses a button
and a clown pops up and music plays. The student presses another button (on a Speech Generating
Device) and a voice utters “Hi, my name is Paul.” What’s the difference in these two scenarios? To the
student, none! A toy is a toy is a toy. The student may have a basic sense of cause and effect (also
known in the literature as “contingency awareness”), enough, say, to realize that when s/he hits the
button something interesting or fun happens. Expanding that notion to have that student comprehend
and “buy in” to the fact that the voice that is produced by the second button is now supposed to be
HIS/HER own voice (and that the button is a tool for COMMUNICATING a message) is, or can be, a much
more high-level abstraction. We, as teachers and caregivers, may understand this concept and take it for
granted—our students, on the other hand, may not be able to grasp this immediately.
Consider for a moment how we learn to use tools in general. You pick up a hammer, and
deliberately and consciously hit a nail. Try it again, and you realize that you can join two pieces of wood
together. Do it enough times and it becomes second nature—an unconscious motor pattern that
produces a certain result. Now consider driving a car: a much more sophisticated set of visual, motor,
and cognitive patterns. When we first learn to drive, it takes a great deal of attention and cognitive
“juice” to stay on top of having the car move intentionally and not crash. Do it enough times, however,
and it also becomes second nature. We react unconsciously to various traffic patterns, putting just
enough pressure on the gas pedal to get us up to the speed limit. In one sense, the car has become an
extension of our bodies—and we “indwell” (in philosopher Michael Polanyi’s terminology) the
object/tool: sensing the environment through our gauges and the sound and response of the tires on
rough or smooth pavement and modifying and adjusting our fine motor control and reacting
appropriately to keep the car moving safely toward a destination.4
Introducing a specialized AAC “speech generating box” as a tool for communicating has similar
implications. At first, the student is interested in simply making the interesting vocal sound effects by
pressing the buttons. The box will likely remain a curiosity or a toy until WE as communication partners,
by our responsiveness and interactions in a communicative context, can convince/teach the student that
the box is actually a tool and has value as a means for affecting other people and their behavior. Using it
many times and getting these kinds of results consistently can promote the student’s ability to “indwell”
the box and consider it an extension of his/her body—a “voice prosthesis” and tool for communicating.
(Like becoming accustomed to having a prosthetic artificial limb, except this one speaks!)
That said, a student will naturally continue to use whatever modality is near at hand and easy
and effective for the situation. Pointing to an apple when s/he is hungry. Crying when s/he is
uncomfortable or sad. Waving when a good friend walks in the door. The sum total of a person’s
4
There has been a lot published recently about neural plasticity and how the brain can incorporate tools into an
expanded body image. See for example the recent Scientific American article, “You Are What You Touch: How Tool
Use Changes the Brain's Representations of the Body” by Patrick Haggard and Matthew R. Longo (Sept. 7, 2010).

7
“multimodal communicative palette” may include speech (verbalizations), verbal approximations,
vocalizations (and voice inflection), gestures (e.g., pointing), manual sign or sign approximations, facial
expressions, eye gaze, body orientation or movement, and proxemics (approach/avoidance to a
communication partner), etc. Multimodal communication5
is our natural means of expression—all of us
use different modes of expression constantly and are able to “read body language” when we are
interacting with others. Much more additional information is conveyed in this manner than would be
possible through single modes. In these contexts, using a complex, high-tech, speech-generating device
might sometimes be cumbersome and ultimately less effective (it is unnatural to expect anyone to
choose a more complicated method of communication over an easier and more efficient one). It is
when students need to refer to something not present, not available, or not easily represented by less
sophisticated means that more complex modes of AAC can become indispensable.
In terms of practicality, and fostering the most “robust” AAC system, it is important to promote
flexibility and have alternative means available for when the primary mode of communication is
unavailable for whatever reason: if the high tech device is broken or malfunctioning, for example. In
addition, students might need to be able to use different communication modes in different social
circumstances—what might seem appropriate with friends in an informal interaction would be totally
out of place interacting with a teacher, or with new relatives at a wedding, for example. Similarly, a
student who communicates with his/her paraprofessional with manual sign language would need to
have the flexibility to communicate via a different mode in the community with individuals who do not
understand sign.
AAC EVALUATION
An Assistive Technology Communication Evaluation can be conducted formally or informally, by
school-based teams, private therapists, or clinics and ideally, includes input from ALL the relevant
stakeholders (“It takes a village”): student, family, school, therapists, community members, etc. The
evaluations that our Assistive Technology Team performs are multi-disciplinary (a speech-language
pathologist, an occupational therapist, and a special education teacher) and are based on our four-part
adaptation of the framework described in Nation & Aram (1991):
1. Information gathering,
2. Data collection and analysis,
3. Generating an action plan, and
4. Monitoring and following up (as needed).
Additional details of this process are described thoroughly in our book: BVSD Assistive Technology
Communication Evaluation.

discussion is based on material available on the excellent YAACK website (see the Bibliography).

THE “AAC TOOLBOX” (A GENERAL DISCUSSION)6
When considering a student as a potential candidate for AAC, it is important to be aware of
all of the possibilities that exist as far as appropriate technology is concerned—thoroughly
understanding, and knowing how to use, all of the “tools in the AAC toolbox.” There are several
different AAC classification systems in use at the present time. The one that we have found most
useful is adapted from the presentations and publications of Marilyn Buzolich, the founder and
director of Augmentative Communication and Technology Services (ACTS) and co-founder of the
Bridge School:
 No Tech: These are “unaided” systems an individual uses with no additional tools or technology
such as motor behaviors, gestures, vocalizations, verbalizations (or verbal approximations),
proxemics (approach, avoidance), eye gaze, and facial expressions.
 Low Tech: These are “aided” communication strategies (i.e., requires some type of external
assistance for the symbols) which do not run from a power source--such as picture or object
communication, PECS (Picture Exchange Communication System), partner assisted auditory
scanning, etc.
6
Additional specifics about these categories will be covered in the next section (AAC Setup and Implementation)
and in Appendix A (Specific Examples of Light Tech and High Tech AAC).

9
 Light Tech: voice output communication systems which are typically battery operated and have
a static (non-changing) display such as the Big Mac, Rocker Plate Talker, Step by Step,
Cheaptalk, Tech Talk, Go Talk, Supertalker, or 7-Level Communication Builder.
 High Tech: Systems typically requiring an electronic power source and having a dynamic
(changing—i.e., computerized LCD screen) display such as a DynaVox Maestro, a Prentke
Romich Accent, a Saltillo Nova-Chat or an iPad (with an appropriate AAC app).
AAC (speech generating) devices may have digitized speech output: a time-sampled
replication of actual human speech. You speak, and it records what you say so that the student can
use that utterance in the context of a communicative interaction. AAC devices with synthesized
speech output translate the user’s input (choosing letters, words, or symbols) into computer-
generated speech. Generally speaking, digitized speech is more natural sounding than synthesized
speech in terms of pitch, resonance, and prosody.

AAC SETUP AND IMPLEMENTATION
Student Preferences
In order to communicate intentionally, two factors are absolutely crucial: 1. that the student has
a clear awareness of the relationship between his/her behavior and the behavior of another person
(social contingency awareness: “cause and effect” between people) and also, 2. that s/he has something
specific to communicate about. The magic ingredient here is “communicative intent”—if the student
has nothing to express, s/he will not communicate! For this reason, it is crucial to have some prior
knowledge of the student’s likes and dislikes, otherwise communication will be intermittent, non-
intentional, or non-existent. Student preferences can be discussed during parent and staff interview
sessions (information gathering) which are a crucial part of planning and preparing for the actual
assessment time with the student. Alternatively, the student can be presented with a succession of
possible types of sensory stimuli and careful note can be made of his/her reactions. The Every Move
Counts Clicks & Chats sensory assessment can particularly effective in this regard (as can the Tangible
Symbol Systems protocol). Eventually, it is ideal to generate a list of preferred, tolerated, and non-
preferred items so that AAC implementation and teaching can proceed smoothly.
Communication Functions
Once we have an idea about what the student likes and dislikes, these items can be presented
to the student and s/he can:
 Request reinstatement of a preferred activity/item
 Refuse a non-preferred activity/item
 Choose between two items (both preferred)
 Choose between two items (one preferred and one non-preferred) and more than two items
 Comment on the item and/or activity
When the preferred objects are present and available (or if the student is ambulatory and can retrieve
the item on his/her own) there is no real need to use symbols or to go through the trouble to
communicate with another person. It is when the item is NOT available for some reason—if it is being
held by the communication partner or if it is out of the student’s line of sight—that a request for
reinstatement becomes important.
Prompting Patterns
Students may need to be prompted to engage in communication. If prompts are used, careful
note should be made regarding whatever prompting patterns are employed (including the precise
wording of a verbal prompt)—prompts can be integral factors in generating an intervention and AAC
implementation protocol.

11
There is a distinction between “cues” and “prompts.” Providing a cue is providing the
antecedent stimulus just before a particular behavior takes place. e.g., the music stopping just before
having the student hit the switch to play a radio. Frequently the student needs help in learning to
respond to a cue. The prompt is a reminder that follows the cue to make sure the student responds to
the cue. There are six common types of prompts:
 verbal (or signed) prompts (making sure to keep your words simple and consistent);
 pictorial or written prompts (photos, line drawings, words, etc.);
 gestural prompts (pointing);
 model prompts (demonstrating what the student is expected to do);
 partial physical prompts (a light touch or tap);
 full physical prompt (hand-over-hand)
A number of different prompting systems can be used and the one most often recommended for our
students who use AAC is the “least-to-most” hierarchy. This is essentially providing the natural cue first,
allowing for sufficient wait time, and then if there is no response, proceeding down the hierarchy
sequentially (as needed) through verbal, gestural, modeling, partial and finally, full physical prompts.
Wait Time
Wait time or “latency of response” time is also a crucial thing to be aware of and to measure: it
can vary tremendously from student to student, activity to activity, and session to session. It is ideal to
allow unlimited or maximum latency time and note the average, minimum & maximum, and if it seems
useful, to use a scatter plot graph to determine “optimal range” wait time—this is key to intervention &
developing effective teaching strategies.
Attention Span
Attention span is another crucial thing to consider—how long the student can spend “on task” before
his/her performance deteriorates, s/he gets tired, distracted, falls asleep, etc. This can obviously vary
day to day and activity to activity, and should be measured over a series of sessions in order to develop
a reliable sense of the student’s “range of attentiveness.”
Access Issues
The AAC tool needs to be positioned properly so that the student can access it consistently and
intentionally. If it is out of reach, or not available, it is useless to anyone! Direct selection is a method of
access in which the individual specifically indicates the desired item in the selection set without any
intermediary steps. There are four types of direction selection methods used for AAC devices/strategies:
a) pointing with physical contact and force; b) pointing without physical contact; c) pointing with contact
and no force; and d) picking up and exchanging. For those individuals who are unable to motorically
access an AAC system by means of “direct selection” (pointing, grasping, etc.), indirect selection or

12
switch access might be a possibility--i.e., pressing an electronic switch or multiple switches using specific
part(s) of the body. As switch access progresses in complexity to include multiple choices, it sometimes
introduces “scanning” which refers to a technique for making a selection (using a small number of
switches) as a sequential display of a set of items is presented. (It can be a useful means of access when
direct selection movements are limited, too fatiguing, or lack accuracy.) It should be noted that
scanning is commonly considered to be a much more difficult physical, cognitive, and sensory task for
students than direct selection: it is slower and more laborious, involves substantial waiting, and requires
the student to have the cognitive ability to comprehend or learn what a “sequence” of choices means.7
AAC IMPLEMENTATION: A SAMPLING OF POSSIBILITIES
SOME BASIC COMMENTS:
So we have determined the student’s likes and dislikes, best means of access, wait time, etc. and
now we are sitting down with the student with the AAC system, whatever it may be: pictures, a speech-
generating device of some sort, whatever... How do we proceed? It may be tempting to simply ask
him/her to “Point to red” or “Choose dog” but while that type of activity is great for learning vocabulary,
symbol identification, and passively following directions—excellent educational goals in their own
right—this is not really expressive communication.8
This is passive responding to questions, not active
initiation and it is not directly helping the student to communicate something s/he needs or wants to
express. It’s only when the student’s COMMUNICATIVE INTENT is present that we are really using the
system or device as an AAC tool—a tool to help expressive communication. We have to look at the
student’s likes and dislikes, motivators and distractors, and set up situations in which s/he WANTS to tell
us something. This is bonafide communication.
There are quite a number of specific strategies or “established methods” for AAC
implementation currently available—some of them can be quite effective (depending on circumstances),
and most of them are based on solid research. A slight problem: experts disagree in interpretation and
approach, sometimes quite dramatically! Some recommend starting off with pictures and/or low tech
strategies, while others absolutely insist on introducing high tech speech generating devices as quickly
as possible. So who to believe, and which approach to choose? The best answer that we have found is
“It all depends.” It all depends on your specific goals, it all depends on the student involved and his/her
learning profile, it all depends on the setting and the communication partners. Are we looking at
functional communication—communicating very basic wants and needs? Are we looking at generating
complete grammatically-correct sentences or conversational turn-taking? Does the student need to give
a class presentation where everything is pre-programmed into a device? “It all depends” means that
we may want to look at one strategy or device in one set of circumstances and quite another strategy in
another. Despite the absolute BEST of intentions on the part of device manufacturers and company
representatives, theoreticians, authors, etc., etc., ONE SIZE DOES NOT FIT ALL and it behooves us, as
7
See the relevant discussion in Ratcliff, 1994. For more information on switch access, please refer to Got Switch,
What’s Next?, the Switch Progression Road Map, and Every Move Counts, Clicks & Chats (see Bibliography).
8
Research has shown that symbol recognition/matching are different skills from using the symbols to
communicate --if you want the student to COMMUNICATE, you have to set up “communication situations” and
practice communicating. (see for example, Stephenson & Linfoot, 1996, and Beukelman & Mirenda, 2005, p. 196)

13
caregivers and teachers to customize the strategy to fit the student, NOT the other way around!
Technology can be a godsend--but APPROPRIATE technology is what we really need and want for our
students. Otherwise we may wind up with (as we have sometimes seen!) a device lying dusty on a shelf
because of a mis-match with the student’s true communicative needs, or a student hiding his/her device
because s/he doesn’t want to appear “different.” Acceptance/adoption and abandonment are CRUCIAL
to consider, ESPECIALLY when we are talking about devices that can cost many thousands of dollars.
As previously mentioned, specific AAC implementation strategies can include “no tech,” “low
tech,” “light tech,” and/or “high tech” approaches:
IMPLEMENTATION--NO TECH:
“No Tech” intervention strategies for working with, and teaching students with Complex
Communication Needs generally fall under the purview of the attending Speech-Language Pathologist.
Discerning and enhancing the student’s communicative intent,9
promoting joint attention and play skills,
encouraging peer interactions, refining verbal and/or manual sign approximations—all of these are part
and parcel of the SLP’s daily work routine using unaided No Tech strategies. When these traditional
methods are insufficient, additional “tools” (AAC) may become necessary or desirable. It is important to
keep in mind that introducing these additional tools into the mix, whether they might be low or high
tech aids, adds a level of complexity which necessitates some form of training—again, convincing the
student that the tool is in fact not a plaything, but is a bonafide means of expression. Cynthia Cress’
published work on “Communication Tools” is extremely useful in this regard: carefully considering how
many “tools” or “hard things” the student must actively control to accomplish a communication goal.
For example, spontaneous communication (reflexive) would simply entail using behavior (one hard
thing/tool). Adding to this mix an object or person as communication partner (intentional behavior—
cause/effect) would entail using two hard things or tools: the student’s behavior plus the person/object.
Symbolic communication can add up to five or more tools (behavior plus message plus person plus
language plus object) and a device or picture would be in addition to that.10
Two possible unaided No Tech strategies that need to be mentioned: the use of Sign Language
and the use of natural gestures (particularly Stephen Calculator’s system of “Enhanced Natural
Gestures”). Sign Language might be an ideal system for some of our students with Complex
Communication Needs since their hands are always available for communication, some of the signs are
“iconic” (they resemble the item or action they represent), and the “system” itself has unlimited
potential (American Sign Language or ASL is a wonderfully rich and complex language). A disadvantage
might be that not all communication partners in the student’s environment will understand ASL. For
those students who experience fine motor difficulties or have trouble learning sign language, learning
and using some Enhanced Natural Gestures (ENGs) might be a possibility. ENGs are intentional motor
behaviors that already exist in a student’s repertoire or can be easily taught, and easily understood by
the observer. The specific gestures might already be associated with a particular item or activity; for
example, a student might lift a cup to his/her mouth to take a drink. Lifting his/her hands in the same
way WITHOUT the cup present would constitute an Enhanced Natural Gesture.

IMPLEMENTATION--LOW TECH THROUGH HIGH TECH:
 Tangible Symbol Systems (Rowland & Schweigert, 2000) is a method of fostering
communication for individuals with severe disabilities who are unable to understand the meaning of the
abstract symbols used in formal language systems. The system uses concrete or “tangible” symbols--
objects or pictures that stand for (or represent) something about which a student needs to
communicate. Tangible symbols may be whole objects, parts of objects, associated objects, textures or
shapes, line drawings, or photographs. They are “permanent” (they exist in a permanent display and
don't have to be recalled from memory), and may be manipulated by both the user and the
communication partner. Most importantly, the relationship between a symbol and its referent is
obvious to the individual user, since it is based on the user's own experience.
Tangible Symbol Systems quick points to consider:
 Consider this strategy when the student is a “Level 1” (Emerging) or possibly a “Level 2” (Beginning Symbolic)
communicator according to our BVSD schema (see P. 5)
 Introducing symbols works best when the student already exhibits communicative intent. If s/he does not,
that would likely be a crucial skill to target first. See the book “First Things First” listed in the Bibliography.
 Not all students can relate to pictures and/or photographs as symbols—you may want to try objects.
 Don’t just rely on Boardmaker pictures because they are easy or convenient—the point is to find the symbol
that is relevant to the STUDENT.
 Data sheets provided in the Tangible Symbol Systems manual are especially useful for determining student
preferences and assessing symbol discrimination.
 Refer to the wealth of free information on the Design to Learn website: www.designtolearn.com especially the
Educational Resources Page and the excellent Communication Matrix Assessment.
 Every Move Counts Clicks & Chats (EMC3
)—The EMC3
system is a comprehensive sensory-
based approach for assessment and intervention to use with individuals with Complex Communication
Needs (functioning below the 18-month level) and severe multiple disabilities. The EMC3
protocol
includes specific assessment strategies to identify what sensory experiences (e.g. auditory, visual,
olfactory, tactile, gustatory, or vestibular) are having an effect on the child, and how to expand this and
promote communication. The system synthesizes research in the areas of communication disorders,
learning theory, sensory integration, and vision, and the emphasis is on assessment, copious data
collection, promoting communication, and using switches (if this is appropriate). The manual includes all
types of record keeping forms, activities, and carry over materials so that the student can engage at the
appropriate level of difficulty (not too hard, not too easy).
EVERY MOVE COUNTS CLICKS & CHATS quick points to consider:
 Consider this strategy when the student is a “Level 1” (Emerging) or possibly a “Level 2” (Beginning Symbolic)
communicator according to our BVSD schema (see P. 5)
 The assessment sections are EXCELLENT (especially the sensory assessment), if this information is unknown.
 This is a unified, comprehensive system for students, covering basic communicative intent, switch access, and
the functional use of AAC.
 This system does NOT use prompting as a strategy (in order to avoid “prompt dependence”).

15
 Picture communication strategies typically begin with teaching the student to associate a
picture (photo, or line drawing) with a specific preferred activity or object. The student indicates in
some way (by pointing, grasping and giving, using gesture or eye gaze, etc.) the desire for the object or
activity, which is then provided. Once this general pattern has been learned, the student then learns to
distinguish between the different pictures, usually by being presented with a preferred activity along
with a “foil” or non-preferred activity. If the student chooses the preferred activity, s/he receives the
reward. If the student chooses the foil, s/he is offered the non-preferred activity, and is thus given a
powerful incentive to learn to distinguish between the pictures correctly. Having the facilitator randomly
switch picture positions (right to left, left to right) helps to avoid position bias (e.g., always choosing the
picture on the left side). Presented pictures choices can increase from a field of one or two on up to an
entire “communication board” or “communication book” with dozens of possible choices, arranged
(usually) in terms of category. Two examples of formalized picture communication systems are the
popular “PECS” (Picture Exchange Communication) system of Frost and Bondy and Gayle Porter’s
“PODD” (Pragmatic Organization Dynamic Display).
Picture Communication quick points to consider:
 While this is sometimes considered synonymous with PECS, there are actually many different ways of using
pictures for communication purposes—PECS is simply one of those ways and is a strict, systematic, and
behavioristic approach to communication (see below)
 Consider experimenting with different types of images: photographs (color and black and white), line
drawings, hand drawings, Boardmaker PCS symbols, product labels or restaurant logos, etc. The key is to
choose the type of representation that is most relevant to the student.
 Consider various ways of displaying the pictures: on a communication board (cardboard or hardboard with
pictures attached with Velcro), communication books, etc. Also consider different ways of arranging the
pictures: via categories (lunch, recess, snack time, circle time), via parts of speech (subject-verb-object), or via
“carrier phrases” (“I want...” “I like...”)
 Pictures can be paired with words to foster word recognition.
 The Picture Exchange Communication System (PECS)--PECS is a behaviorally-based picture
communication system designed for children with social-communicative deficits. Using PECS, expressive
communication skills are targeted through the training of requests and, later, comments. PECS begins
with teaching the student to exchange a picture of a desired item with a facilitator, who immediately
honors the request. If the student wants food, s/he gives a picture of food to the facilitator who gives
them the food. In order to encourage a student’s spontaneous communicative intent and avoid prompt
dependency, verbal prompts are not used during the first stages of the training process. The PECS
system progresses through six phases, step-by-step, through the initial stage of requesting (one picture,
one object or activity) through choice-making (multiple pictures, multiple objects or activities), and
eventually to stringing together several pictures into a rudimentary syntax (“I want cookie please”) and
making responsive and spontaneous comments. The PECS system is intricate and formal (facilitators
attend multiple-day workshops and are guided by a 400 page manual) and it is ideally suited to foster
communication in individuals with autism, and others who have challenges with communicative intent.

16
PECS quick points to consider:
 PECS was originally designed for students on the Autism spectrum to help with initiating communication, but
may be applicable for others as well (especially if communicative intent is an issue).
 The initial stage of PECS is crucial and is ideally performed with TWO trainers, one to interact with the student
face-to-face, and one to stand behind and guide the student’s hand to the picture
 Be flexible: if the “typical” Boardmaker pictures do not work, try photographs and/or objects.
 Use the error correction procedures described in the PECS manual closely for best results.
 Consider transitioning to voice output devices when the student has mastered Phase IV of the PECS protocol
and has a large vocabulary and a sense of sentence structure (see Frost & McGowan in the Bibliography).
 Aided Language Stimulation--Aided Language Stimulation is a useful strategy for successful
augmentative communication use that involves having the communication partner point out symbols on
the communication display as s/he interacts and communicates verbally with the student. This modeling
of the communication system assists the student to establish a visual and auditory understanding of
how symbols can be combined and recombined generatively to communicate during routine activities.
Aided Language Stimulation is useful for non-verbal students as well as for students who are language
delayed. In a typical situation, the printed word accompanies each symbol on the display, and so Aided
Language Stimulation also may assist some children in the development of reading skills. When
providing aided language stimulation for children, Carol Goossens recommends the following verbal
language stimulation guidelines:
o use primarily single words (symbols) and short grammatically correct phrases (symbol
phrases) to talk about what the child is hearing, seeing, doing and feeling
o use lots of repetition as you describe ongoing events
o speak slowly, inserting numerous pauses into the conversational flow
o whenever the child indicates something with a single word (symbol), expand that message
into a semantically equivalent two-word (symbol) combination.
AIDED LANGUAGE STIMULATION quick points to consider:
 Consider this strategy for students at ANY level of communicative ability.
 Consider this strategy for students who use ANY type of AAC: pictures, objects, speech generating device, etc.
 Since it involves MODELING, it is an excellent way of enhancing students’ receptive communication as well as
teaching them to express themselves via certain specific patterns.
 LAMP (Language Acquisition through Motor Planning)— Language Acquisition through
Motor Planning (LAMP) is a therapeutic approach based on neurological and motor learning principles,
using word-based (generative language) speech-generating devices, particularly ones that feature the
Unity or Minspeak system of vocabulary organization (made by the Prentke Romich company). The goal
is to give individuals who are nonverbal or have limited verbal abilities a method of independently and
spontaneously expressing themselves in any setting. LAMP focuses on giving the individual
independent access to vocabulary on voice output AAC devices that use consistent motor plans for
accessing vocabulary. “Every word has a unique motor plan.” (Each consistent pattern of one, two or

17
three hits on the AAC device must always result in production of a unique word.) These motor patterns
are meant to reflect the consistent and unique motor patterns that result in the production of speech.
Teaching of the vocabulary happens across environments, with multisensory input to enhance
meaning, with the child's interests and desires determining the vocabulary to be taught. LAMP
researchers have found that when these strategies were used with nonverbal children with Autism,
they were found to increase the ability of the children to communicate spontaneously in any
environment using unique combinations of words to express themselves. It was often noted that as
communication skills improved, social engagement increased, problematic behaviors declined, and
some individuals exhibited increased verbal speech.
LAMP quick points to consider:
 This strategy was originally designed for students on the Autism Spectrum who use speech generating devices
to communicate, but it may have other applications as well
 It is ideally suited to the Unity/Minspeak system featured in Prentke Romich devices; however, the general
principles can apply to ANY word-based, generative language system of AAC (e.g., Word Power, Gateway, the
Sonoflex iPad app, etc.)
 Since LAMP is based on motor memory, symbol (picture, word) recognition is not as prominent as in many
other systems.
 Since repetition and motor memory are emphasized with LAMP rather than symbol recognition, students who
exhibit position bias (i.e., a preference for choosing items on a certain side) or who have a proclivity for
repetitive fine motor movement may possibly need additional prompting to meaningfully use this system.
 PODD (Pragmatic Organization Dynamic Display)—The PODD system was designed by
Gayle Porter, an Australian Speech Pathologist, and it refers to a series of student
communication books that are organized by the different pragmatic functions of language. The
books feature quick chat pages, pragmatic branch starters, and pages designed to allow the
student to discuss or comment on the topic initiated (PODD messages flow from one page to
the next by way of page numbers that guide the student through a conversation.) There are
PODD communication books designed for several different language levels and they all provide
extensive vocabulary: for continuous communication all the time, for a range of messages
across a range of topics, and in multiple environments. Communication partners and teachers are
also encouraged to use and model the PODD books for communication (using Aided Language
Stimulation techniques—see above) and gradually the student becomes familiar with the system and
more independent.
PODD quick points to consider:
 The PODD “system” is for sale by Mayer Johnson in the US, and it uses Boardmaker picture symbols.
 The PODD books are fairly extensive, but because of the system organization, conversational “branches” are
fairly easy to follow.
 The system encourages users to “always begin on the front page with a pragmatic branch starter” and allows
the conversational partner to navigate the levels for the student as s/he is learning.

18
 General strategies for AAC implementation-- There are a number of general strategies that
may prove useful for introducing AAC into a student’s routine so that s/he can participate more
effectively in the classroom. Perhaps the most important general principle is to, as much as possible, set
up “communicative temptations” into the student’s routine. This can be difficult at first, since our
natural tendency as educators and caregivers is to help him/her out as much as possible and save
him/her any trouble. The key idea is to sabotage an expectation and make him/her work (i.e., learn how
to communicate a need) for his/her reward. It’s possible to encourage the student’s “need” for
requesting, using a communicative temptation by:
o Time delay—preferred items or activities are present but access is delayed until s/he makes
a request.
o Missing item—An item needed for a preferred activity is missing.
o Blocked response (interrupted behavior chain)—Momentarily blocking a response or
interrupting an ongoing activity.
o Verbal prompt-free strategy—A symbol is placed near the student (with no accompanying
prompt or explanation) and if s/he touches it intentionally or not, the item is provided.
o Incomplete presentation—His/her initial request is followed by a partial presentation of the
requested item (only part of a puzzle, for example)
o Delayed assistance—Needed assistance is delayed until s/he makes a request.
o Wrong item format—S/he is given the wrong referent (activity or item) and needs to repair
the mistake.11
In addition, if a voice output device is being introduced, the device can be fitted with symbol/object
prompts by simply taping or velcroing the symbol to the appropriate place on the top of the device. Care
needs to be taken that the student’s use of a voice output device is driven by communicative intent and
it is not simply the desire to derive auditory or tactile stimulation from hitting the button repeatedly.
This can be assured by carefully structuring the communicative environment such that s/he gets the
appropriate social encouragement and reinforcement as quickly and effectively as possible.
When the goal for the student involves multiple utterances, sequencing utterances, and/or
taking turns, scripted routines can be pre-planned, practiced, and implemented into appropriate social
interactions. Taking part in a play at school might be a possibility here, as would pre-planning an
interaction with a store owner or restaurant worker in the community (asking about the price of an
item, ordering food, etc.). Many additional possibilities can be found in Beukelman & Mirenda (in
Chapters 10 & 11) and in our handout in Appendix D: Assistive Technology & Communication:
Encouraging Your Students In The Classroom.

VOCABULARY/SYMBOL DISPLAY & ARRANGEMENT: A BRIEF DISCUSSION
The purpose of a communication display is to arrange language in space so individuals can, by
selecting from the available options, say what they wish to say as quickly as possible, and can
do so with a minimal amount of effort. (Blackstone, 1993)
Static (or fixed) displays are those on which the symbols do not change automatically when the
user activates a particular button or touches a particular symbol, object, picture, or icon. One page must
be removed and replaced by another one in order to access additional vocabulary. Typical examples
include paper communication boards and books, object boards, and light tech speech generating
devices that feature the “one button, one message” approach to organizing symbols. Dynamic displays
are those on which the language symbols are electronically generated on an LCD screen and change
automatically as a normal part of operating the device. The student touches a single symbol and can
access multiple overlays automatically.
Other important considerations for displaying symbols for the student include:
 the optimal size and shape of the array (one by two? two by four? seven by twelve?),
 the size, shape, and color of the symbols (4” X 4”? 2” X 2”? Smaller?),
 the TYPE and “iconicity” or abstractness of the symbol (photograph, line drawing with
background, line drawing without background, abstract shape, etc.)
 and, of course, the choice and precise arrangement of the vocabulary.
Again, it is important to decide what the specific goals are for the interaction and maintain as
much flexibility as possible: should the messages be individual words or phrases? Will we need to
prompt the student to access the correct “page” of vocabulary for the desired activity? Do we need to
emphasize nouns, verbs, or both for the message to be comprehensible to the unfamiliar
communication partner? What are the goals—functional communication? Language generation?
Information presentation? All of the above?
Picture communication books can be arranged in terms of topic or “category” (home,
recess, lunch, snack time) and some speech-generating devices (both digitized and synthesized) use
a “leveling” approach to language storage and retrieval. Traditional “leveling” systems such as the
DynaVox Interaact “child user” or “teen user” incorporate a phrase-based approach to
communication: you press one button and a phrase or sentence like “I need to go to the bathroom”
will be spoken. Light tech devices with a static display that use a leveling strategy (such as the 7-
Level Communication Builder or the Supertalker) require multiple overlays.
Picture communication books can also be arranged so that the student can construct
sentences word by word (I--want--cookie) or by using “carrier phrases” (I want—cookie). In certain
speech generating devices this can also be the case. Strategies that are word-based such as the
DynaVox “Gateway” build up a message word-by-word according to the rules of grammar—the
approach is slow, but allows for the possibility of generating novel or unique utterances
(“generative language”). Hybrid systems are also available (e.g., incorporating “Gateway” with the
traditional DynaVox “users”) for a combination approach.
Devices that use the Unity or Minspeak system of symbol or icon organization (these are
designed by Prentke Romich or “PRC”) are word-based, and are loosely organized according to

20
“parts-of-speech” (e.g., pronouns on the left, verbs on the right, activities on the upper activity
row). They use “multiple-meaning icons” as choices: the picture of William Shakespeare can be used
to build up a statement about reading (since he was an author) or the future tense “will” (as in
“Will” Shakespeare). Similarly, the picture of the apple can be used to build up a statement about
eating or growing. Bruce Baker has been the driving force behind Unity or Minspeak (also called
“semantic compaction”) for many years. PRC devices (ECO, Vantage Lite, Springboard Lite, and the
newer Accent series) have Unity/Minspeak as their starting point, but now also incorporate some
leveling and phrase-based strategies to a certain extent.
A newer approach to AAC is called “visual scenes” and has been shown in some recent
studies to be an extremely effective way to organize vocabulary and promote communication.12
Visual scenes are images (they can be either digital photographs or illustrations) which show
activities, people, and objects in relation to one another and the natural environment. For example,
a visual scene may be a photo of the student’s classroom with books on his/her desk. S/he may
point to or touch the book image to refer to a homework assignment or (on a device) to open up a
dialog box to engage in a conversation relating to the assignment. In general, visual scenes provide
much more information than symbols representing single concepts, so that the student and his/her
communication partner can understand CONTEXT and MEANING more accurately and completely.
Bottom line, there are various approaches to choosing, displaying, and organizing AAC
system symbols and vocabulary, but there is no one “right way” for all situations. Again: “it all
depends!”
FOLLOWING UP
The overall goal and gauge for successful use of AAC should be “communicative competence”—
a term used by Janice Light13
to refer to the student having skills in four domains: operational, linguistic,
social, and strategic. Operationally, students need to learn to apply the necessary motor, cognitive, and
sensory (i.e., visual/auditory) skills needed for actually operating their AAC systems (setting them up or
turning them on, making choices, etc.). Linguistically, students are learning the structure and patterns of
their system’s linguistic code (vocabulary and grammar): pictures, words, manual sign, etc. and socially,
they are using these linguistic codes during actual interactions with others: choice making, requesting,
rejecting, and initiating, maintaining, repairing, and terminating conversations. Strategic skills are the
abilities and the compensatory strategies needed to communicate despite having significant
operational, linguistic, and social impairments: being able to get the message across no matter what the
situation may be.
AAC ADOPTION AND ABANDONMENT: A BRIEF DISCUSSION
Caregivers and teachers need to be able to foster the student’s communicative competence
with AAC in any way they can, in every situation that the student encounters. It is an unfortunate fact,
12
See the discussions in Drager et al, 2003, Drager, et al, 2004, and Light et al, 2004.
13
See Light, 1989 and Light, Beukelman & Reichle, 2003).

21
though, that despite the best of intentions on the part of all concerned parties, AAC is abandoned at an
alarmingly high rate. What accounts for this? According to teachers and staff, lack of training, time
constraints, technical problems, and lack of support are some of the primary reasons. Time is extremely
precious in the classroom and not many can devote the necessary time and prep work for customizing a
system for each student in the class, and troubleshooting a system that goes down for whatever reason.
For students, the pressure to fit in with peers and not be singled out as “different” or “disabled”
can be a truly significant deterrent. We knew one student who had his own custom-programmed state-
of-the art AAC device who never brought it to school, and in fact hid it under his bed to try and prevent
his mother from sending it in with him each day! This is perhaps a dramatic example, but we see it to
varying degrees with many other students as well. Another deterrent for students might be if the system
is a poor fit for his/her needs. If the messages that are available are not something that the student
wants to communicate, or if communication partners do not understand his/her message correctly, s/he
will become frustrated and abandon the AAC. In addition, if the system is too difficult for the student to
understand (e.g., if the student is at a pre-symbolic cause/effect level and the system calls for
generating complete sentences), or if s/he can’t operate the system quickly enough to produce a usable
message, s/he will also become frustrated and not use the system.
Participant characteristics of successful AT adoption. (from Kintsch & Depaula, 2002)
The above chart outlines some important stakeholder characteristics that might lead to the
successful adoption of an AT (or AAC) system or strategy. From the chart, we can appreciate that all AAC
stakeholders need to be “in the loop”: the AAC user, his/her family, the school team, the assistive

22
technology specialists, private therapists, the developers, etc. “Buy in” and commitment from all parties
is essential! Without it, we are much more likely to be unsuccessful with our efforts: a strategy or
system may be absolutely effective in one setting, but totally inappropriate for another. That said, there
is nothing wrong with using different strategies in different settings—again: “think multi-modal!” But, it
would be ideal if the student’s primary means of communication, his/her “primary voice,” would be
versatile and robust, easily transferable between settings. This is much more likely IF the assessment
and AAC determination process has been performed effectively, and IF all stakeholders have been
actively involved in the process.
Caregivers, educators, and peers can go far in helping promote AAC usage! Strategizing and
planning ahead—“engineering the environment”--can be an extremely effective means of AAC systems
implementation.14
First, the daily routine is analyzed in order to identify possible opportunities for
communicative interaction and then the AAC system is customized appropriately: overlays are created,
messages are recorded, and devices are pre-programmed and customized. Finally, the student is taught
to use the system effectively in context. Complete and accurate data keeping is absolutely crucial in this
stage in order to maximize the possibility of acceptance and adoption. Data should include issues such
as when and how the system is used (and for what purposes), how effectively it is used, student, peer,
and teacher reaction and comments, the clarity of the intended message and any instances of
communicative repair, etc. Many types of data sheets are possible (depending on the specific goals and
activities), and several examples are included in the Appendix to this workbook (Appendix B).
SPECIAL CONSIDERATIONS AND BRIEF DISCUSSIONS
 A BRIEF DISCUSSION ABOUT USING “YES/NO” AS VOCABULARY OPTIONS
When introducing two-option choice making into an AAC system it is often quite tempting to
use “yes” and “no” as the choices. It’s simple, clear, elegant, multi-purpose, and seemingly easy to
comprehend (at least from our perspective). And so it turns out to be, in SOME, perhaps most,
situations—again, “it all depends.” However, it should be noted that requiring a yes/no response may
be problematic for some children as this concept tends to be a later-developing cognitive and
communicative skill. “Yes” and “no” can have a wide variety of meanings and results, and the
interpretation of those words is dependent upon the question being asked. “Do you want milk, yes or
no?” “Are you happy, yes or no?” “Do you agree with the recent Supreme Court decision, yes or no?”
According to Cynthia Cress, “…even after children begin to use yes and no appropriately, they tend to
vary in their success at answering questions that require a yes/no response across linguistic contexts,
and frequently make errors in saying either yes or no when it does not match their communicative
intent.” If warranted, consider using other more “direct” words as choices.
14
This phrase is taken from the work of Goossens, Crain, & Elder.

23
 A BRIEF DISCUSSION ABOUT USING iPADS AS AAC DEVICES
For the brief period of time that mobile devices such as iPads, iTouches, and iPhones
(“iDevices”) have been available they have proven to be amazingly popular items, and have quickly
become useful and effective tools for education, entertainment, AND communication. Communicating
with others via the iPhone and the Internet are obvious functions, and, for students with Complex
Communication Needs, there are now a large number of powerful AAC apps available that transform the
iDevice into a Speech-Generating AAC device. Advantages of using iDevices as AAC tools are obvious:
 Low price (less than $1000)
 iDevices are multi-purpose tools: there are many apps: 500,000+ total, 200+ for AAC
 iDevices can access the internet
 iDevices have a “coolness” factor for students, and give instant peer acceptance
 iDevices have a digital camera
 iDevices are extremely portable and elegant
As with any other AAC strategy we have considered, one size does NOT fit all, and despite their instant
and undeniable appeal, iPads will not be an appropriate choice for all students in all situations. “It all
depends.” Some disadvantages to consider...
Physical access can be a significant problem for some students—is s/he able to isolate finger
motions? Is s/he able to swipe or pinch? Can s/he see what is on the screen? The situation is improving
considerably with newly marketed switch interfaces and apps designed for scanning, but at this point, it
is still a significant consideration. Another question would be whether the student understands what a
picture represents or whether s/he can comprehend synthesized speech (a computer voice). In addition,
iPad apps are nowhere near as complex and “robust” as fully-functional AAC software, so that a student
might be poorly served by a relatively simple iPad app when s/he might really need the power and
capability of a DynaVox or PRC or Saltillo (or other) device.
A final disadvantage might actually be one of the already-listed advantages: multi-functionality
and versatility. Traditional speech-generating devices have always had the communication software as
their main function and purpose. You get a Vantage Lite or a MiniMo, and you are not going to make
phone calls with it or surf the web. Even with the tablet-based devices such as the Prentke Romich ECO2
or the DynaVox V, it was difficult or at least awkward to close down the communication software and
use them as anything other than what they were sold as: speech-generating AAC devices. Not so with
the iPad! It is just as easy (and perhaps easier and even more desirable?) to boot up a fun game such as
Angry Birds as it is to open up Proloquo2Go or Touch Chat or one of the other AAC apps. The difficulty
now becomes one of distractibility – is the iPad an AAC device (a “voice prosthesis” to help the student
communicate), an educational tool, a toy, or all of the above? Why should the student want to boot up
an AAC app when Angry Birds is more fun? Should we close off ALL other apps except the AAC app of
choice so that we have a “dedicated” speech-generating device? (This type of lock-out is possible with
the “Guided Access” feature in iOS 6: Settings > General > Accessibility > Guided Access) Or will this type
of approach be counter-productive, spoil the multifunctional appeal of the iPad, and ignore its “insanely
great” power and versatility? An informal email poll we did of about a dozen or so international AAC

24
experts produced answers across the spectrum: a few suggested that the iPad, if used as an AAC device,
should be a DEDICATED device—close off all other apps as distractions (or else have TWO iPads with
different color cases—one for educational/entertainment purposes, and one for JUST communication).
Several experts responded that there should be NO restrictions—a tool is a tool is a tool and why deny
the power and range of the iPad’s full capability? Finally, several of the responses held to a middle
ground of sorts, echoing the sentiments that we have expressed throughout this manual: “it all
depends.” It all depends on the student (whether s/he is distractible), the context, the communication
partners, and the overall goals—the who, what, when where, how, and WHY of the situation.
Ultimately, iPads and apps are TOOLS (“cool gizmos,” but tools, nevertheless). Some possible basic
questions to ask might be:
o What is it that you want the student using the iDevice to do, learn, examine, discuss, and
think about? (What do you want the iDevice and app to do?)
o Create a list of what you want to do first so that you don’t get distracted by the extra bells
and whistles.
o How will the technology help to accomplish the student’s communication goals?
o Do the features meet the needs of the student?
o Do the iDevice features work in this environment?
o Does the iDevice address the tasks which the student is expected to perform?
o Does this tool align with curriculum, teaching method, IEP goals, etc.?
 A BRIEF DISCUSSION OF USING FACILITATED COMMUNICATION AS AAC
Facilitated communication (FC) is a technique in which a “facilitator” (a therapist, teacher, or
caregiver) gives a student consistent direct or indirect physical (and other) supports in an attempt to
promote communication: pointing to pictures or objects, pointing to printed letters or words, or typing
on a computer keyboard. According to personal anecdotal accounts and descriptions, this type of
technique may reveal previously undetected literacy and communication skills in students with autism
and other severe disabilities.15
Although publicized FC success stories are both dramatic and impressive, it should be noted that
this strategy is considered “controversial” by both the American Psychological Association (APA) and the
American Speech-Language-Hearing Association (ASHA) in their 1994 and 1995 Position Statements,
respectively.16
In their view, in many cases it can be unclear who is really doing the communicating and
how much help the communicator is really obtaining from the facilitator. Numerous studies that have
been conducted have failed to show that this technique is in fact a consistent and dependable means for
expressive communication (i.e., it is not repeatable across settings and facilitators). Because of this, we
cannot ethically or professionally recommend it as a general AAC strategy, especially since we run the
risk (especially with an inexperienced or insensitive facilitator who might have a “heavy-handed”
approach) that we might actually disempower or discourage our student’s communication attempts
rather than facilitating them.

 A BRIEF DISCUSSION OF “AAC IN THE IEP” (GENERAL SUGGESTIONS)
In Section 7 (Consideration of Special Factors), letter G. “Does the student need Assistive Technology
devices or services?” The “Yes” box can be checked, and a description of the specific assistive
technology can be given after the prompt “If yes, please specify.” When describing assistive technology,
avoid brand names. Naming a particular device or software program only locks a student in to using that
specific product, which may become obsolete or may not be appropriate in a given situation. Flexibility
in the IEP allows the student’s team to find and use the most appropriate tool for each task. Rather,
describe the necessary assistive technology and the function it performs. For example:
 Rather than “DynaVox” write “dynamic screen speech-generating communication device.”
 Rather than “Big Mack,” write “Message recording communication device.”
 Rather than “AbleNet Control Unit,” or “Big Red Switch,” write “Switch access for environmental
controls, communication, and computer access.”
In Section 10 (Accommodations and Modifications), the AAC strategy or system can be included under
“Accommodations-- What type(s) of accommodation(s) if any is (are) necessary for the student to access
the general curriculum and/or appropriate activities to make effective progress?” Answers can vary
depending on the technology in question—several examples are:
 Access to a picture communication book.
 Access to a text-to-speech AAC device for communication.
 Access to a speech-generating communication device.
In Section 9 Annual Goals and/or Objectives, the assistive technology can be included as a part of the
goal or objective—NOT as the main focus of the goal, but as a TOOL to accomplish that goal. Focus on
the desired outcome or skill, the “essential learning” and/or the communicative function --what does
the student need to do? “The student will *read, write, speak, etc.+...” Describe in detail the
criteria/evaluation and necessary accommodation. Use of equipment/devices as accommodations or
levels of assistance can be included in goals and objectives in much the same way as assistance by an
adult would be described. Here are some specific examples:
SIMPLE MESSAGES:
Goal: By his/her next annual review date [the student] will independently greet peers and staff using a
single-message recording device (e.g. “Big Mack”, “One Step,” “Step-by-Step”, etc.) in at least 4 of 5
opportunities.
Baseline: Student greets peers and staff in 1 out of 4 opportunities.

26
COMPLEX COMMUNICATION DEVICES:
Goal: By his/her next annual review date, [the student] will demonstrate appropriate conversational
turn taking techniques using a multiple-message communication device (e.g. “Supertalker,” “DynaVox
V,” “iPad with Proloquo2Go app) for 3 or more conversational turns with peers and/or staff in at least 3
out of 4 opportunities.
Baseline: Student takes 1-2 conversational turns in 2 out of 4 opportunities.
CHOICE MAKING:
Goal: By his/her next annual review date, [the student] will initiate interactions and make appropriate
requests using stylized line drawings depicting desired objects and/or actions from a field of two given
choices in at least 4 of 5 opportunities with verbal prompting.
Baseline: Student makes requests using stylized line drawings from a field of two in 1 out of 4
opportunities with verbal and gestural prompting.

LEVELS OF COMMUNICATIVE ABILITIES
Our own three-level schema is compared with Rowland and Schweigert’s in the diagram above. This is
further expanded in their books and website at www.designtolearn.com
There are a number of developmental schemas for language acquisition, and they vary slightly
from case to case; some overlap, some emphasize one skill over another, some are sequenced
somewhat unevenly and to compare them or to reconcile them with each other is really “splitting hairs.”
Many of them are based on the original proposed by language researcher Elizabeth Bates— this schema
has been used many times17
(She revised some of the categories used by philosophers John Searle and
John Austin in their “speech act” theory):
Perlocutionary--reflexive behavior by the individual is interpreted by the caregiver as meaningful and
communicative and then acted upon,
Illocutionary--intentional communication but does not use symbols,
Locutionary--The individual is able to intentionally use words or another symbol system.
17

SPECIFIC EXAMPLES OF LIGHT TECH AND HIGH TECH AAC STRATEGIES (PARTIAL LIST)
LIGHT TECH:
 A single-message speech-generating device such as a “Big Mack” or “One Step” with a static
display--these are versatile and can be used in many different situations; they are quick-to-program and
use digitized speech (you record a message); and they can easily be fitted with pictures (photos or
picture symbols) velcroed onto the device.
• A two message speech-generating device such as a “Rocking Plate Talker” or “iTalk2” with a
static display—these are versatile and allow for the possibility of choice-making or a sequenced message
of some kind; they are quick-to-program and use digitized speech (you record messages); and they can
be easily “fitted” with pictures (photos or picture symbols) velcroed onto the device.
• A wearable message recording device such as a “Hip Talk” (a message recording device that can
be worn around the waist like a “fanny pack”) with a static display—these are versatile and very
portable and can be used in many different situations. They are relatively easy to program, use digitized
speech (you record messages) and they can be easily “fitted” with pictures (photos or picture symbols)
velcroed onto the device.
• A single button message sequencing device (digital speech—the actual human voice) with a
static display such as a “Step-by-Step.” This type of device offers the possibility of sequencing a
message: telling a joke, singing a song, relating a longer narrative or parts in a play, etc.
• A multiple-message (single level) voice output device with a static display such as a Cheaptalk-4
or Cheaptalk-8 (using digital speech—the actual human voice). These devices have a relatively limited
range, but they are quick and easy to program and extremely versatile. They can be easily “fitted” with
pictures (photos or picture symbols) velcroed onto the device.
• A multiple-message (multiple level) voice output device with a static display such as a 7-Level
Communication Builder or Supertalker (using digital speech—the actual human voice). These devices
have a relatively limited range, but they are quick and easy to program and extremely versatile. They
have multiple levels (or pages) that can be programmed with 1, 2, 4, 8, (or 16, with the 7-level)
messages. They can also be easily “fitted” with pictures (photos or picture symbols) velcroed onto the
device.
HIGH TECH:
• A computerized, voice output device with a dynamic display (an LCD touch screen) and digitized
(recorded) speech such as a MiniMo or an M3. These devices are DynaVox devices and use a “leveling”
approach to organizing vocabulary: you press one button and a whole phrase or sentence like “I need to
go to the bathroom” will be spoken. Hit another button, say for “school” and another page or level
opens up. Once one navigates to the proper level (levels are usually organized by category), the total
message is related quickly.

37
• A computerized, voice output device with a dynamic display (an LCD touch screen) such as an
Alt-Chat or Nova Chat (Saltillo), a DynaVox V+, Maestro, or Xpress (DynaVox), a Springboard Lite, a
Vantage Lite, an ECO2 or one of the newer Accent series devices (Prentke Romich), or a Say-It! SAM or
TuffTalker (Words Plus). These high-end devices have communication software which features high-
quality synthesized speech (computer voices) and the possibility of accommodating communicators at
different skill levels, from beginner to advanced. Although all of these devices are extremely versatile,
several devices (e.g., the DynaVox models) primarily emphasize a phrase-based leveling or visual scene
approach, whereas others (e.g., the Prentke Romich models) primarily emphasize a word-based or
generative language approach.18
• A computerized text-to-voice device with a dynamic screen (an LCD touch screen) such as a
DynaWrite 2.0 (DynaVox) or a Lightwriter (Toby Churchill) or else less expensive voice output portable
word processors such as the Fusion (Writer Learning Systems) or the Neo (Renaissance Learning). There
are text-to-voice features on most of the high-tech AAC devices as well, so that displayed text can be
combined with pictures/icons, as needed.
• Computerized, voice output apps loaded onto the iPod Touch or iPhone or iPad. This type of
system is the latest for portability and functionality and there are various AAC apps which can
accommodate leveling (e.g., Proloquo2Go), generative language (Proloquo2Go, SonoFlex, LAMP Words
for Life, or the Word Power add-on app to the Touch Chat suite), or text-to-speech strategies
(TextToSpeech, TTS, Speak It!, Speak It To Me, Speak Bot, Write&Say, Easy Speak, iSayIt, iSpeakIt, Voice
Generator, etc.). There are hundreds of AAC apps available as of this writing, with additional ones being
added every day
With apps featuring the “leveling” approach to organizing vocabulary you press one button and
a whole phrase or sentence like “I need to go to the bathroom” will be spoken. Hit another button, say
for “school” and another page or level opens up. Once one navigates to the proper level (levels are
usually organized by category), the total message is related quickly. You can usually customize the
software very easily to accommodate communicators at different skill levels, from beginner to
advanced.
With apps featuring the “generative language” strategy to organizing vocabulary, you build up
sentences word-by-word by pressing the appropriate pictures/icons (usually organized in terms of parts
of speech). Apps which feature this approach usually have accommodations for communicators at
various skill levels, from beginner to advanced.
18
The lines have blurred significantly, especially in recent years, as the DynaVox devices also feature easy access to
the “Gateway” User Areas (very much word-based and generative), and the Prentke Romich Unity-based devices
allow for limited phrase-based statements.

Tracking Device Use
by Caroline Musselwhite
WHAT AND WHY?
This form was developed to support teachers, parents, and
therapists in building accountability, and observing when .
. . and how . . . devices and communication displays are
used. I have tried to keep it simple, so that it is more likely to
be implemented.
HOW DO YOU USE IT??
1) First, be sure to get a baseline! Use this form at the beginning of the school year,
when introducing a new communication device, when
implementing a new training approach, etc.
2) Study the prompting and cueing hierarchy, to increase your familiarity with
terminology. It is fine to make up your own prompting and cueing key, to meet the needs
of YOUR classroom and teaching style!
3) Plan ahead for how long you will wait before repeating assessment using the
checklist.
4) Set goals to be met for the next assessment such as:
a) Will increase availability of appropriate device / vocabulary across
daily activities
b) Will provide appropriate modeling, using aided language stimulation,
for at least three activities
c) Will reduce prompt dependency by offering less intrusive prompts (e.g.,
moving from hand over hand to use of light cues)
DESCRIPTION OF CATEGORIES
Time of Day: track at least 5 activities during the day. Consider picking them at
random (write activities on pieces of paper & pull from bowl) so you don't 'cheat' and
observe activities that are the 'best' or 'worst'!!
Activity: be as specific as necessary to allow comparison with future checks
Device: list all light & high tech devices the student can actually use for the activity
Vocabulary / Overlay: check whether the student has available vocabulary or the
appropriate vocabulary to accomplish the task.

AAC SETT WORKSHEET
(©2008, Minneapolis Public Schools Assistive Technology Center, used by permission)
The following worksheet is a useful tool for taking data and evaluating the efficacy of an AAC strategy, and
can also serve as a quick protocol for an initial evaluation or a re-evaluation of a student who may need
assistance with his/her current method(s) of communication. It is based on the “SETT” Framework
pioneered by Joy Zabala and takes into account: Student, Environments, Tasks, and Tools. (see
http://www.joyzabala.com/). The third and fourth pages of the worksheet (reproduced also in the previous
section—Appendix B) can be adapted and can be particularly useful for periodic “probes” during classroom
implementation of AAC strategies.

ASSISTIVE TECHNOLOGY & COMMUNICATION:
Encouraging Your Students in the Classroom
“Augmentative or Alternative Communication (AAC) is any device, system, or method that improves the
ability of a child with a communication impairment to communicate effectively.” Encouraging these
students to use augmentative/alternative communication (AAC) strategies in the classroom can be
challenging. The following are some general and more specific suggestions and ideas...
General Suggestions
 Collaborate and strategize with all staff and parents: teachers, SLPs, OTs, PTs, paras, etc.
 Make sure all staff are trained on AAC device usage (if necessary)
 “Think multimodal”—a speech generating device can be used in one context, picture symbols in
another. We all communicate in multiple modes (speech, gesture, smiles, etc.)
 Program age- and peer-appropriate vocabulary—“gross,” “cool,” “what’s up?”
 Include appropriate negative comments on the student's AAC system
 Use sabotage and temptations for increased communication opportunities. For example, give your
student a fork to eat his/her cereal with or skip a student’s turn in a fun activity and see how s/he
problem solves this "mistake."
 “Engineer the Environment”:
o Identify and prioritize communication activities that occur throughout the day. The best
teaching moments occur during “real life” activities in context.
o Develop message sets for each activity using the student’s AAC system.
 Plan and use scripted routines for longer turn-taking (two-three-four exchanges)
 Organize the AAC user’s physical environment
o Access: Appropriate positioning of the AAC
o Access: Appropriate organization of the symbols for fast retrieval
o If the student is using a dynamic screen device, does s/he know where to find the
information? Has s/he had time to explore and practice the pages?
o Does s/he have something s/he wants to talk about?
o Set the AAC user up for success!!!
 Communication strategies for facilitators:
o Encourage peers to figure out messages from the AAC user.
o Expect a response every time.
o Respond to any attempt by the student to communicate as you would any other child.
o Confirm the intended message; clarify if unsure.
o Have a shared focus—confirm the same topic.
o Vary meaningful activities and provide choice making and opportunities for comments,
greetings and other interactions throughout the day.
o Do not talk for or respond for the student
o Learn to “Wait” 20 or 30 seconds—It seems like a long time to wait. It’s not!
o Model--Adult shows how to interact using the talker: “You do it” “You try”
o PROMPT only when REQUIRED: Wait, don’t hover--aim for independence.

o Possible prompts can include:
 telling your student to "use his/her words" (e.g., verbal reminders)
 illustrating the correct symbol choice using sign language or other visual
representation without pointing to your student's actual communication board
(e.g., visual prompts)
 modeling pointing to the correct symbol (e.g., gestural prompts)
 verbally stating the correct response (e.g., verbal model)
 physically helping your student point to the correct symbol (e.g., physical
assistance)
 REMEMBER TO ALLOW ADEQUATE WAIT TIME!
Specific Ideas for Younger Students
Arrival
 Yes/No questioning-regarding hot or cold lunch option for the day.
 Live voice scan regarding who student wants to be his/her "helper" for the day or who s/he wants to
sit by at circle time.
 Single message devices can be used to greet staff or peers.
 A Step-by-Step (message sequencer) can be used to allow for communication regarding arrival
topics, such as requesting assistance with removal of outerwear or items in a backpack.
 The student can use a multiple location device to make comments or respond to questions.
Literature Activity
 A two-choice communication system can allow the student to participate in pre-reading activities
such as choosing books, selecting a reader, or selecting the type of voice used to read the story.
 A single message device can be used for the student to request that the page of a book be turned or
the repetitive line of a story be read.
 The student can use eye gaze to identify vocabulary words upon request.
Post-Literature Activity
 A picture communication board can be used for the student to comment on a story or to make
requests. For example, "That's scary," "That's funny," "Read it again."
 Yes/no questions or live voice scan can be used to assess the student's comprehension of the book.
Social Studies
 The student can activate a Step-by-Step (message sequencer) to call on peers or identify a state and
have a peer name the corresponding capital.
 The student can use a switch-activated spinner to select a picture symbol of a state and activate a
single message device to request the name of the state.
 Picture symbols can be sequenced to represent events of a trip.
 A multiple location overlay can be used on a voice output device to direct peers to move from
location to location on a map.

Math
 The student can use a switch-activated spinner to select numerals to create math calculation
problems for their classmates to compute.
 A multiple location overlay can be used on a voice output device for the student to identify values of
mixed groups of coins.
Sharing
 Velcro can be used to attach a souvenir onto a single message device. The student can activate a
prerecorded message to give details about his/her souvenir to the class.
 The student can demonstrate an electrically powered toy with a switch, activated with an AAC
device.
 The student can demonstrate a battery-operated toy using a switch with a battery device adapter.
 A multiple location overlay on a voice output device can be used for the student to direct peers in a
multiple step recipe or experiment.
 The student can ask peers questions or make comments using a multiple location communication
device.
Lunch
 The student can use a customized lunch tray, lunchbox, or placemat with picture symbols to make
comments or requests in the lunchroom setting.
 The student can use any multiple location voice output device to order lunch items.
Recess
 Wristbands can be created with digital photos for choice making between recess activities (e.g.,
swing, slide).
 The student can wear a fanny pack or a janitor key ring with photos or picture symbols representing
choices for recess activities, peers to play with, or general comments/requests.
 The student can use a play mat for indoor recess. For example, place picture symbols on a placemat
for a bubble-blowing activity (pop it, blow a big bubble, and blow a small bubble).
 A Step-by-Step message sequencer can be used to direct peers during a game situation (Simon
Says).
Departure
 The student can use a single-message device to relay a message about events of the school day to
the home setting.
 Live voice scan can be used to have the student select whom they want to sit by on the bus.

Specific Ideas for Older Students
 Participate in specific events that require contextual messages (e.g., singing a song that is pre-
programmed, e.g., “Happy Birthday” or “For He’s a Jolly Good Fellow”)
 Say (or lead) the Pledge of Allegiance
 Cheer or boo a favorite sports team
 Converse on the telephone
 Greetings and departures
 Comment on things (“This food is disgusting”) and activities (“Yeah—this is cool!”)
 Indicate enthusiasm (“I want more”) or the need to discontinue an activity (“I need a break”)
 Ask questions (“What’s your name?” “What’s your favorite music?”)
 Maintain the conversation with optional comments like “Really?” or “Uh-huh.”
 Make requests in predictable situations (“I’d like a cheeseburger”)
 Initiate conversations or introducing topics (“How was your weekend?”)
 Make introductions between people
 Tell a knock-knock joke (e.g., using a Step-by-Step message sequencer)
 Recite a scripted series of lines in a class play
 Relate pre-programmed academic information to the class during a classroom presentation
 Dictate the words in a spelling test to the rest of the class
 Engage in simple, predictable conversations that involve turn-taking
 Participate in a predictable song with repeated lines (“We all live in a Yellow Submarine”)
 Discuss the season and weather in a structured classroom routine
 Relate the day of the week and the date in a structured classroom routine
 Discuss upcoming events of interest to the class

 Discuss what s/he did over the weekend/summer break in a structured classroom or conversational
routine
 Relate daily “school news to home” and “home news to school”
 Converse about personal information: family members, address, phone number, pets, favorite
music, favorite sports, etc. in structured and unstructured discourse
 Give information about personal preferences (“I like Hip Hop music.” “My favorite movie is Pirates
of the Caribbean.”)
 Give information about emotions (“I’m happy”) and physical status (“I feel tired.” “I feel sick.”)
 Participate in an educational “game” played by the class or group of students
 Interface the AAC device with a computer to participate in literacy activities:
o Reading—using text readers such as WYNN
o Writing—using onscreen keyboards, word prediction (e.g., Co:Writer), using email
 Interface the AAC device with a computer to surf the web for information.

AUGMENTATIVE AND ALTERNATIVE COMMUNICATION (AAC):
AN INTRODUCTION
WHAT IS AAC?
For students with complex communication needs (i.e., those unable to meet their daily communication
needs through “natural” modes such as speech) speech-language services can be helpful, as well as
some form of assistive technology accommodation: “Augmentative and Alternative Communication”
(AAC) can be defined as any device, system, or method that improves the ability of a child with a
communication impairment to communicate effectively. It can include sophisticated devices and
systems (sign language, communication boards, or speech-generating devices) as well as less
sophisticated means (pictures or objects used as symbols, etc.) AAC is introduced when the student
does not develop communication in the typical fashion, or experiences significant delays, and is used to
AUGMENT or add to (not replace!) whatever communication the student possesses, as part of a
“multimodal” system. A few indicators for introducing some form of AAC might include: a moderate to
severe expressive speech/language disorder, an expressive/receptive language gap (the student
understands more than s/he can say), limited speech or expressive language improvement with therapy,
and/or the student’s frustration at his/her inability to communicate messages effectively.
SOME TYPES OF AAC
 No Tech: These are “unaided” systems an individual uses with no additional tools or technology
such as motor behaviors, gestures, vocalizations, verbalizations (or verbal approximations),
proxemics (approach or avoidance of a communication partner), eye gaze, and facial expressions.
 Low Tech: These are “aided” communication strategies (i.e., requiring some type of external
assistance for the symbols) which do not run from a power source. Examples: picture or object
communication, the Picture Exchange Communication System (PECS), partner assisted scanning, etc.
 Light Tech: voice output communication systems which are typically battery operated and have a
static (non-changing) display such as the Big Mac, Rocker Plate Talker, Step by Step, Cheaptalk, Tech
Talk, Go Talk, Supertalker, or 7-Level Communication Builder.
 High Tech: Systems typically requiring an electronic power source and having a dynamic (changing—
i.e., computerized LCD screen) display such as a DynaVox Maestro, a Prentke Romich Accent, a
Saltillo Nova-Chat or an iPad (with an appropriate AAC app).
AAC (speech generating) devices may have digitized speech output: a time-sampled replication of actual
human speech. You speak, and it records what you say so that the student can use that utterance in the
context of a communicative interaction. AAC devices with synthesized speech output translate the
user’s input (choosing letters, words, or symbols) into computer-generated speech. Generally speaking,
digitized speech is more natural sounding than synthesized speech in terms of pitch, resonance, and
prosody.

AN INTRODUCTION
WILL USING AAC PREVENT A STUDENT FROM USING OR DEVELOPING NATURAL SPEECH?
The research says: NO! It may actually improve speech.
Two recent articles (Millar, Light, & Schlosser, 2006, and Schlosser & Wendt, 2008) reviewed all of the
previously-published research that had investigated speech production before, during, and after AAC
intervention. NONE of the individuals involved in any of the studies demonstrated decreases in speech
production as a result of AAC intervention. The majority demonstrated at least modest gains in speech
(a small percentage showed no change).
AAC is sometimes viewed as a “last resort,” to be considered only after years of speech language
therapy have proven unsuccessful. In reality, AAC can be used very effectively in conjunction with
therapy, and may enable the student to immediately participate in communicative interactions with
peers and others in school, at home, and in the community. While speech is always the most natural
way to communicate, there are definitely other excellent possibilities, and it is essential that a student
has SOME means of consistent control over his/her environment. AAC can be a useful TOOL, to be used
when it is most appropriate: AAC strategies can be customized and upgraded over the lifetime of an
individual (e.g., introducing different or more sophisticated devices, if warranted), or else faded
completely if other natural modes (such as speech) improve.
***There have been NO published studies that show decreased speech production as a result of AAC.
WHY MIGHT AAC INTERVENTION (e.g., SPEECH GENERATING DEVICES) IMPROVE SPEECH?
Consider the following:
 AAC can encourage the student to be less of a passive observer during communicative interactions
and more of an active participant.
 AAC may increase the number of messages that are possible and increase the length of the student’s
utterance.
 AAC produces immediate acoustic output (the message), is effective across many environments, and
offers a consistently-produced “speech model” for the student to listen to and imitate.
 The acoustic output can be paired with the visual symbol (word, picture, or icon), thereby
strengthening the connection between the spoken word, graphic symbol, and the referent (what the
symbol refers to).
 Hearing oneself produce speech via a speech-generating device may help stimulate and develop the
brain mechanisms utilized for speech production (“internal phonology”)

AN INTRODUCTION
ARE THERE ANY “PREREQUISITES” (e.g., AGE OR COGNITION) FOR USING AAC?
The current research says: NO! If needed, AAC interventions can be introduced at ANY time.
Chronological age is sometimes mentioned as an argument against the provision of AAC services: “The
student is too young to benefit.” However, there is absolutely no evidence to verify this position!
Current research clearly documents the efficacy of AAC for infants, toddlers, and preschoolers.
In addition, in years past, clinicians had hesitated to recommend AAC interventions until the student had
attained a certain cognitive level (“cognition” is the ability to think, solve problems, remember, etc.)—
This position has been shown in many studies to be totally unfounded: while cognition and
communication skills are related, they can (and in many cases do) operate independently.
Experts agree: there is no reason to delay the start of AAC programs for individuals with severe
disabilities and, in fact, there are many compelling reasons for beginning communication intervention at
a young age even if certain cognitive skills have not been attained.
MULTIMODAL COMMUNICATION: AN EXPLANATION
What is it? Multimodal communication is the use of more than one type of communication method or
mode during an interaction. It can include speech (verbalizations), verbal approximations, vocalizations
(and voice inflection), gestures (e.g., pointing), manual sign or sign approximations, facial expressions,
eye gaze, body orientation or movement, proxemics (approach/avoidance to a communication partner),
as well as the use of aided AAC strategies (pictures, objects, speech generating devices, etc.). Basically,
it includes anything that an individual can do in order to communicate a message.
Multimodal communication is natural. Multimodal communication is our natural means of
expression—all of us use different modes of expression constantly and are able to “read body
language” when we are interacting with others. Much more additional information is conveyed in this
manner than would be possible through single modes.
Multimodal communication is flexible. People need to be able to use different communication modes
in different social circumstances—what might seem appropriate with friends in an informal interaction
might be totally out of place interacting with your teacher, or with your new relatives at a wedding, for
example. Similarly, a student who communicates with his/her paraprofessional with manual sign
language would need to have the flexibility to communicate via a different mode in the community with
individuals who do not understand sign.

AN INTRODUCTION
Multimodal communication is easy. Students will always rely on the easiest and simplest means of
expression, as long as it is effective. If they can point, they will point; if they can smile, they will smile to
let you know they are happy; if they can guide you by the hand to get a snack, that is the way they will
naturally let you know they are hungry.
High tech is not always “best tech.” Using a complex, high-tech, speech-generating device is a powerful
and versatile means of communication for students with complex communication needs, but it might
actually be cumbersome in certain circumstances. It is unnatural to expect anyone to choose a more
complicated method of communication over an easier and more efficient one! For example, if the
student can wave a hand to greet you, why make him/her scramble to find the “hello” button on the
DynaVox or PRC Accent? High tech definitely has its place, but it is most important to be flexible,
especially for times when the high tech device may not available for some reason.
CONCLUSIONS?
1. AAC strategies encompass a range of possibilities, from “no tech” and “low tech” to “high tech”
and can be used effectively as part of a student’s “multimodal” system of communication.
2. AAC strategies are meant to augment (add to) and not replace, a student’s natural means of
communication.
3. The introduction of AAC intervention will NOT impede natural speech. In some cases AAC may in
fact improve speech production, but this will vary from person to person.
4. There are specific advantages (and NO disadvantages) to using AAC strategies.
5. There are no prerequisites for introducing AAC.

Communication Bill of Rights
(1992 Joint Committee for the Communication Needs for Persons with Severe Disabilities)
All persons, regardless of the extent or severity of their disabilities, have a basic right to
affect, through communication, the conditions of their own existence. Beyond this general
right, a number of specific communication rights should be ensured in all daily interactions
and interventions involving persons who have severe disabilities. These basic communication
rights are as follows:
1. Request desired objects, actions, events, and person, and to express personal
preferences or feelings.
2. Be offered choices and alternatives.
3. Reject or refuse undesired objects, events, or actions, including the right to decline or
reject all preferred choices.
4. Request and be given attention from and interaction with another person.
5. Request feedback or information about a state, an object, a person, or an event of
interest.
6. Active treatment and intervention efforts to enable people with severe disabilities to
communicate messages in whatever modes, and as effectively and efficiently as their
specific abilities will allow.
7. Have communicative acts acknowledged and responded to, even when the intent of
these acts cannot be fulfilled by the responder.
8. Have access at all times to any needed augmentative and alternative communication
devices and other assistive technology devices, to have those devices in good working
order.
9. Environmental contexts, interactions, and opportunities that expect and encourage
participation as full communicative partners with other people including peers.
10. Be informed about the people, things, and events in one’s immediate environment.
11. Be communicated with in a manner that recognizes and acknowledges the inherent
dignity of the person being addressed, including the right to be a part of communication
exchanges about individuals that are conducted in his or her presence.
12. Be communicated with in ways that are meaningful, understandable, and culturally and
linguistically appropriate communications.
