This document outlines three different taxonomies for classifying levels of knowledge, skills, and attitudes (KSA):
1. Silva's Cognitive Domain taxonomy describes 6 levels of knowledge - from remembering to creating.
2. Simpson's Psychomotor Domain taxonomy lists 7 levels of skills development - from perception to origination.
3. Harrow's 1972 taxonomy outlines 6 levels of psychomotor skills - from reflex movements to non-discursive communication.
The taxonomies provide examples of each level to illustrate the progression in complexity of knowledge, skills, and abilities.
