Levels of Cognition

Based on Bloom’s Taxonomy – Revised (2001)  In addition to content specifics, the subtext for  each topic in this BOK also indicates the intended complexity level of the test questions for that  topic. These levels are based on “Levels of  Cognition” (from Bloom’s (from  Bloom’s Taxonomy – Revised, 2001) and are presented below in rank order, from least complex to most complex. Remember (Knowledge Level) Recall or recognize terms, definitions, facts, ideas, materials, patterns, sequences, methods, principles, etc. Understand (Comprehension Level)  Read and understand descriptions, communications, reports, tables, diagrams, directions, regulations, etc.  Apply (Application Level) Know when and how  to use ideas, procedures, methods, formulas, principles, theories, etc.  Analyze (Analysis Level) Break down information into its constituent parts and recognize their  relationship to one another and how they are organized; identify sublevel factors or salient  data from a complex scenario. Evaluate (Evaluation Level)  Make judgments about the value of proposed ideas, solutions, etc., by comparing the proposal to specific criteria or standards. Create (Synthesis Level)  Put parts or elements together togeth er in such a way as to reveal a patte pattern rn or  structure not clearly there before; identify which data or information from a complex set are appropriate to examine further or from which supported conclusions can be drawn.
