The Knowledge category embodied both noun and verb aspects. The noun
or subject matter aspect was specified in Knowledge’s extensive subcategories. The verb aspect was included in the definition given to Knowledge in that the student was expected to be able to recall or recognize knowledge.

One Dimension

The categories were ordered from simple to complex and from concrete to abstract. It is  represented a cumulative hierarchy.
- Knowledge
-  Comprehension
- Application
- Analysis
- SyNthesis
- Evaluation

A proposed hierarchy of understanding that can be used to evaluate a student's comprehension of a topic. From the highest level to the lowest level of understanding, they are:
- Creation / Create
- Evaluation / Evaluate
- Analysis / Analyze
- Application / Apply
- Comprehension / Understand
- Knowledge / Remember


Bloom's Taxonomy of Learning

Bloom's taxonomy comprises three hierarchical models used to classify educational learning objectives into levels of complexity and specificity:
- Cognitive domain (knowledge-based)
- Affective domain (emotion-based)
- Psychomotor domain (action-based)

A Revision of Bloom's Taxonomy: An Overview

The suggested formula can be used to control for  the difference in difficulty between different exams. This allows researchers to weigh courses and exams differently based on the perceived difficulty of the exam content. However, to assign a Weighted Bloom's Index to a exam or question, special training is needed.

Revised Bloom's Taxonomy

The affective domain is one of the three hierarchical models in Bloom's taxonomy. It is an emotion-based model used to classify educational learning objectives.

Affective Domain in Bloom's Taxonomy

The psychomotor domain is one of the three hierarchical models in Bloom's taxonomy. It is an action-based model used to classify educational learning objectives.
