23 Describe the overall assessment strategy and specific arrangements
which have been put in place to ensure that assessment is always valid,
reliable and fair and show that these are in line with the requirements of
the NSQF.
(1) Assessment process:
The assessment for the block-based qualification is carried out by conducting
formative assessments, and final examinations. The internal assessments for
theory subjects and practical are conducted by the concerned instructors for
evaluating the knowledge and skill acquired by trainees and the behavioural
transformation of the trainees. This internal assessment is primarily carried out
by collecting evidence of competence gained by the trainees by evaluating them
at work based on assessment criteria, asking questions and initiating formative
discussions to assess understanding and by evaluating records and reports,
and sessional marks are awarded to them. Theory is conducted in Trade theory,
Workshop Calculation & Science, Engineering Drawing and Employability Skills
along with practical examinations. The question papers for the theory
Examinations contain objective type questions. Trade practical examinations are

April 2018)
NSQC Approved 15
conducted by the local board constituted as the defined rule. However, the
question papers for the Trade practical are prepared by NCVT.
The marking pattern and distribution of marks for the qualification are as per
NCVT approved structure issued from time to time.
(2) Minimum pass marks:
The minimum pass percentage for Practical is 60% & minimum pass
percentage for Theory subjects is 40%.
(3) Testing and certifications for the course:
 Online examination conducted for all theory papers.
A panel of expert paper setters, who are graduates in the concerned field with
minimum 5-7 years experience, is prepared for setting question papers for the
Trade. The panel is vetted by the Member Secretary, NCVT.
 Paper setters are appointed from the panel after the approval of the
competent authority for setting the question paper.
 The question papers are then moderated by the Board of Moderation to see
if the paper is set as per the requirement and syllabus.
 An Examination Board consisting of representatives of
industry/Employer/State Government are set up to supervise and monitor the
conduct of Examinations at every Centre.
 Theory and practical Examinations are carried out with invigilators/examiners
with the overall supervision of the Examination Board.
 Examiners called for evaluation of practical should have minimum technical
qualification of a Diploma in the respective engineering field. However, when
diploma holders not available, the qualification is suitably relaxed.
 Examiners for practical Examinations are appointed preferably from
Polytechnics/ Engineering colleges/ expert from establishment/ Government
Departments or from retired qualified personnel possessing requisite
qualifications and sufficient experience in the trade/discipline.
Testing centre located in ITI
Local board of examiners will be constituted in respect of every centre by the
State Director in-charge of Training/State Apprenticeship Adviser in consultation
with the State council for Vocational Training for conducting and evaluating the
Trade test on the spot. The local Board of examiners will consist of the
following:
 State Director in-charge of Training/State Apprenticeship Adviser
(Secretary, State council for Vocational Training) or his nominees (who
must be a duly qualified technical person) as Chairman.

April 2018)
NSQC Approved 16
 Suitable Experts from various industries/Institutions depending on the
trades in which Test will be conducted at the Centre.

Testing centre located in the establishment coming under the purview of
Central Governments
Regional Directors (RDAT) in consultation for conducting and evaluating the
following:
 Chairman appointed by the employer in whose establishment Trade
Testing Centre is located
 Flying squads from State Governments as well as the Central Government
are constituted to check malpractices during the conduct of Examinations.
 Evaluation of every practical examination is carried out by the concerned
examiner (from industry/ polytechnics) with the overall supervision of the
Examination Board in a free and fair manner as per the assessment criteria.
 The marks compiled by the Regional Directors/State Apprenticeship
Advisers as per NCVT guidelines and the results were declared by the State
Governments and RDATs
 The successful trainees are awarded National Apprenticeship Certificates.
Overall assessment strategy:
Assessment of the qualification evaluates trainees to show that they can
integrate knowledge, skills and values for carrying out relevant tasks as per the

April 2018)
NSQC Approved 17
defined assessable outcomes and assessment criteria. The trainees may
choose the preferred language for assessment. The underlying principle of
assessment is fairness and transparency. While assessing the trainee, assessor
is directed to assess as per the defined assessment criteria against the
assessable outcomes. The evidence of the competence acquired by the
trainees can be obtained by conducting theory and practical examinations,
observing the trainees at work, asking questions and initiating formative
discussions to assess understanding and evaluating records and reports. The
ultimate objective of the assessment is to assess the candidates as per the
defined assessment criteria for the assessable/ learning outcomes.
Specific Arrangements for assessment:
• Assessment is outcome-based.
• There are formative and summative assessments in Theory and
Practical.
• Assessment is carried out in Trade theory, Trade Practical, Workshop
Calculation and Science, Engineering Drawing and Employability Skills.
 While Trade Theory and Trade Practical are used for assessing Trade-
related jobs, Workshop Calculation and Science is used to test trainee‟s
numerical skills, Drawing is used to test the ability of the trainee to draw
and read sketches and Employability skills is used to test the
communication and language skills of the trainee.
 In addition to demonstration of theory and practical knowledge, trainees
get a chance to present total personality.
Quality assurance activities:
• Question papers are set by external paper setters
• Evaluation of Theory Examinations is done online.
• Trade Practical is examined by External Examiner (as explained above).

are also generally consulted before finalizing the curricula.
28 What steps were taken to ensure that the qualification(s) does (do)
not duplicate already existing or planned qualifications in the NSQF?
Give justification for presenting a duplicate qualification
The qualification is originally designed and approved by NCVT for the
Apprenticeship Training Scheme and is in existence for more than 50
years. NCVT has been entrusted with the responsibilities of prescribing
standards and curricula for Apprenticeship training, advising the
Government of India on the overall policy and programmes, conducting All
India Trade Tests and awarding National Apprenticeship Certificates.

qualification(s)? What data will be used and at what point will the
qualification(s) be revised or updated? Specify the review process
here
 Mentor Council (MC) for the Production and Manufacturing sector
was formed in 2014 to review the curriculum of this qualification
under the sector.
 CSTARI, the research wing of DGT, reviews and updates the
qualification, in consultation with industries and other stakeholders,
on a regular basis by conducting trade committee meetings.
 DGT will keep on doing continuous comparative study in the trade
by referring to relevant upcoming qualifications in the National
Qualifications Register (NQR) and relevant sectors.
