Bloom's Taxonomy: A Complete Guide for Educators and Assessment Design

Bloom's Taxonomy is arguably the most influential framework in educational assessment design. Originally published in 1956 and revised in 2001, it provides educators with a structured way to think about what students should know, how deeply they should understand it, and how to design assessments that measure the right cognitive skills. If you have ever written a learning objective or chosen action verbs for an exam question, you have used Bloom's Taxonomy — whether you realized it or not.

What Is Bloom's Taxonomy?

Bloom's Taxonomy is a hierarchical classification of cognitive skills arranged from the simplest (remembering facts) to the most complex (creating original work). Developed by educational psychologist Benjamin Bloom and a committee of colleagues, the original framework defined six levels of cognitive complexity in the domain of knowledge.

The revised taxonomy (Anderson and Krathwohl, 2001) updated the original framework with two key changes: it renamed the levels using verb forms (to emphasize that cognition is an active process) and swapped the top two levels, placing "Create" above "Evaluate."

The six levels, from lowest to highest cognitive demand:

1. Remember — Retrieve relevant knowledge from long-term memory
2. Understand — Construct meaning from instructional messages
3. Apply — Carry out or use a procedure in a given situation
4. Analyze — Break material into parts, determine relationships
5. Evaluate — Make judgments based on criteria and standards
6. Create — Put elements together to form a coherent or functional whole

Each level builds on the ones below it. A student who can analyze an argument must first remember the content, understand its meaning, and know how to apply relevant frameworks.

Why Bloom's Taxonomy Matters

Bloom's Taxonomy matters because it prevents one of the most common assessment mistakes: testing students only at the lowest cognitive levels. A multiple-choice exam that asks students to recall definitions tests "Remember" — but if the course objectives require students to evaluate competing theories, that exam is misaligned.

For educators, Bloom's Taxonomy:

• Provides a shared vocabulary for discussing learning expectations
• Guides the writing of measurable learning objectives
• Ensures assessment alignment between what is taught and what is tested
• Supports the design of grading criteria that target appropriate cognitive levels
• Helps build rubrics with clear performance distinctions

For students, Bloom's Taxonomy:

• Clarifies what depth of understanding is expected
• Helps prioritize study strategies (memorization vs. analysis vs. synthesis)
• Makes assessment expectations transparent and predictable

The Six Cognitive Levels in Detail

Remember

Retrieving, recognizing, and recalling relevant knowledge from long-term memory.

Action verbs: Define, list, recall, identify, name, recognize, state, match

Assessment examples: Multiple-choice factual questions, fill-in-the-blank, labeling diagrams, vocabulary matching

Understand

Constructing meaning from oral, written, and graphic messages through interpreting, classifying, summarizing, comparing, and explaining.

Action verbs: Explain, summarize, paraphrase, classify, compare, describe, discuss, interpret

Assessment examples: "Explain the concept of X in your own words," summarize an article, compare two approaches

Apply

Carrying out or using a procedure in a familiar or new situation.

Action verbs: Apply, demonstrate, solve, use, implement, execute, calculate, illustrate

Assessment examples: Solve a problem using a formula, apply a framework to a case study, implement an algorithm

Analyze

Breaking material into constituent parts and determining how parts relate to one another and to an overall structure or purpose.

Action verbs: Analyze, differentiate, distinguish, examine, deconstruct, organize, compare, contrast

Assessment examples: Analyze a data set for patterns, compare theoretical frameworks, deconstruct an argument's logic

Evaluate

Making judgments based on criteria and standards through checking and critiquing.

Action verbs: Evaluate, assess, critique, judge, justify, defend, argue, prioritize

Assessment examples: Peer review, critique a research methodology, defend a thesis position, evaluate the quality of evidence

Create

Putting elements together to form a coherent or functional whole; reorganizing elements into a new pattern or structure.

Action verbs: Design, construct, develop, formulate, compose, produce, propose, synthesize

Assessment examples: Write an original research paper, design an experiment, create a business plan, compose a policy proposal

Bloom's Taxonomy in Practice

Writing Learning Objectives with Bloom's

Every well-written learning objective contains three elements: a condition, an action verb (from Bloom's), and a criterion. The action verb determines the cognitive level being targeted.

Aligning Assessments to Bloom's Levels

A common pitfall is designing course objectives at higher Bloom's levels but assessing at lower ones. If your objective says students should "analyze," your assessment must require analysis — not just recall.

This alignment between objectives and assessments is the core principle of assessment alignment.

Using Bloom's to Design Rubric Criteria

Bloom's verbs provide a natural foundation for writing rubric grading criteria. A proficiency scale can mirror cognitive progression — lower levels for applying knowledge correctly, higher levels for synthesizing and creating original insights.

For example, a research paper rubric might define its "Analysis" dimension as:

• Distinguished: Synthesizes multiple theoretical frameworks to construct an original argument
• Proficient: Analyzes evidence using an appropriate framework with clear reasoning
• Developing: Describes evidence but analysis remains superficial
• Novice: Lists evidence without meaningful analysis

Related Concepts

Bloom's Taxonomy intersects with nearly every aspect of assessment design. Well-defined grading criteria should specify which Bloom's level they target. Rubric design guidelines use Bloom's verbs to write clear performance descriptors. Assessment alignment is fundamentally about matching the Bloom's level of your learning objectives to the Bloom's level of your assessments. A well-constructed proficiency scale often mirrors Bloom's cognitive hierarchy, with lower levels capturing basic recall and application, and higher levels requiring evaluation and creation. The choice between analytic and holistic rubrics can also depend on whether you need to assess multiple Bloom's levels independently.

Frequently Asked Questions

Is Bloom's Taxonomy a strict hierarchy?

The revised taxonomy (2001) acknowledges that cognitive processes are not always strictly sequential. A student might create something novel (Create) that requires application but not deep evaluation. However, in most educational contexts, the hierarchy holds as a useful approximation: higher levels generally presume competence at lower levels.

How many Bloom's levels should an assignment target?

Most well-designed assignments target two to four Bloom's levels. An introductory course might focus on Remember through Apply, while an advanced seminar should target Analyze through Create. The key is matching the levels to your stated learning objectives — not trying to hit all six in every assignment.

Can Bloom's Taxonomy be used for non-cognitive skills?

The original taxonomy included three domains: cognitive (knowledge), affective (attitudes and values), and psychomotor (physical skills). The six-level framework most educators use applies specifically to the cognitive domain. Separate taxonomies exist for affective and psychomotor learning, though they are less widely adopted.
