IASSC Lean Six Sigma Black Belt Study Guide

The IASSC Lean Six Sigma Black Belt Study Guide is a free, quick-reference list of essential materials to prepare for and pass the certification exam. It is derived from the IASSC Universally Accepted Lean Six Sigma Body of Knowledge for Black Belts. In other words, this is what they say you need to know to pass their exam.

Speaking of passing their exam, did you know that 100% of the people who pass my Black Belt practice exams report passing their exam (IASSC, ASQ, Villanova, etc) on the first try? Sign up here. 100% refund within the first 30 days.

Levels of Cognition based on Bloom’s Taxonomy – Revised (2001)

These levels are from “Levels of Cognition” (from Bloom’s Taxonomy – Revised, 2001). They are listed in order from the least complex to the most complex.

Remember: Recall or recognize terms, definitions, facts, ideas, materials, patterns, sequences, methods, principles, etc.

Understand: 
Read and understand descriptions, communications, reports, tables, diagrams, directions, regulations, etc.

Apply: 
Know when and how to use ideas, procedures, methods, formulas, principles, theories, etc.

Analyze: 
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: 
Make judgments about the value of proposed ideas, solutions, etc., by comparing the proposal to specific criteria or standards.

Create: Put parts or elements together in such a way as to reveal a pattern or structure not clearly there before; identify which data or information from a complex set is appropriate to examine further or from which supported conclusions can be drawn.
