Bloom’s taxonomy is a hierarchical model used for classifying learning objectives by levels of complexity and specificity. Bloom’s Taxonomy was created to outline and clarify how learners acquire new knowledge and skills. Though the original intention of the taxonomy was to serve as an assessment tool, Bloom’s taxonomy is effective in helping instructors identify clear learning objectives as well as create purposeful learning activities and instructional materials.
Bloom’s taxonomy emerged from a 1948 meeting of university educators – chaired by Benjamin Bloom – who brainstormed a theoretical model of learning that identified educational objectives to aid in the creation of testing items. The committee later expanded its initial framework to three learning domains:
Bloom’s Taxonomy consists of three learning domains: cognitive, affective and psychomotor.
The cognitive domain went through numerous revisions before a finalized version was published (Bloom 1956).
The cognitive domain has been the primary focus in education and has become shorthand for Bloom’s Taxonomy as a result. The cognitive domain is made up of six levels of objectives. These levels are organized by hierarchy, moving from foundational skills to higher-order thinking skills.
In 2001 Anderson and Krathwohl revised Bloom’s levels from nouns to verbs, and this is the version of the taxonomy used today.

Anderson and Krathwohl’s Two-Dimensional Taxonomy
When revising Bloom’s Taxonomy in 2001, Anderson and Krathwohl also added the knowledge dimension to the taxonomy. The knowledge dimension consists of four dimensions, which are:
Based on this two-dimensional taxonomy, Anderson and Krathwohl developed a matrix for combining cognitive processes and knowledge dimensions which is shown to the left.
See the “How” section of this teaching guide to learn more about using the cognitive domain to craft learning objectives, assessments, and instructional materials and learning activities for your courses as well as how to implement the cognitive domain/knowledge dimension matrix when using Bloom’s Taxonomy in the classroom.
The affective domain was first published in 1964 (Krathwohl et al, 1964). The affective domain outlines skills and behaviors that correspond to attitudes and values and as the learner progresses through the levels of the affective domain, they become self-reliant and internally motivated. Learning objectives aligned to the affective domain tend to be the hardest to articulate initially and often appear difficult to assess at first glance. However, affective outcomes often represent the outcomes most closely related to deeper thinking and lifelong learning.
The affective domain contains five levels, from lowest to highest:
See the “How” section of this teaching guide to learn more about using the affective domain to craft learning objectives, assessments, and instructional materials and learning activities for your courses.
(Krathwohl et al., 1964)
Bloom and his colleagues did not create subcategories for skills in the psychomotor domain, but other educators did (Simpson 1966, 1972; Dave, 1970; Harrow, 1972). The psychomotor domain includes physical movement, coordination, and motor skills. Development of these skills requires practice and is measured in terms of speed, precision, distance, procedures, or technical execution. For the purpose of this teaching guide, we will explore Simpson’s version of the psychomotor domain, which has the following seven levels:
Simpson’s seven levels of the psychomotor domain.
See the “How” section of this teaching guide to learn more about using the psychomotor domain to craft learning objectives, assessments, and instructional materials and learning activities for your courses.
Bloom’s Taxonomy can help you write clear learning objectives, which are a description of what the learner must be able to do upon completion of an educational activity. A well-written learning objective outlines the knowledge, skills, and/or attitude the learners will gain from the educational activity and does so in an observable and measurable way.
More specifically, Bloom’s can help you identify the level, criteria, or standards for the knowledge, skills, abilities, competencies, attitudes, or values that your students are expected to be able to demonstrate.
For the cognitive, affective, and psychomotor domains, there are action verbs that align with each level. These action verbs are invaluable in crafting effective learning objectives.
Use the following steps to craft learning objectives using Bloom’s taxonomy:
Consult the tables below to view action verbs that align with each level of the cognitive, affective, and psychomotor domains, as well as examples for each of the levels.
Cognitive domain
This domain is focused on intellectual skills such as critical thinking, problem-solving, and creating a knowledge base. The cognitive hierarchy consists of six levels, which span from simple memorization designed to build the knowledge of learners, to creating something new based on previously-learned information.

Adapted in part from Bloom’s Taxonomy Learning Activities and Assessments, Centre for Teaching Excellence, University of Waterloo.
There are many ways that Bloom’s can be applied to course planning to ensure effective instruction and student learning is occurring. Several approaches to lesson planning that build on Bloom’s Taxonomy are described below.
Expertise pathwaysRemember the names and relationships of a cast of characters in a play | A multiple-choice test designed to test the memory of learners. |
Explain the main ideas of a play | Write a short (1 page) paper summarizing the plot and most important events in the play. |
Apply the main ideas/themes in the play to another context | Write an advice column responding to one of the characters. |
Analyze the roles of each character in the play and their relationships to each other. | Write an analytical paper comparing the antagonists and protagonists of the play. |
Evaluate the decisions of characters in the play, and support your evaluation with textual evidence. | Write a response to one of the events in the play, either supporting or rejecting their actions on the basis of evidence from the play as well as personal opinion and projected/actual consequences of action. |
Create a new and unique piece of writing using similar plot devices. | Create a short story using similar plot devices in a new time or setting. |
Differentiated instruction is the process of tailoring lessons to meet the needs, interests, strengths, and ability levels of individual students in the classroom. Gershon (2013, 2019) builds differentiation into instruction by splitting up a lesson objective into three outcomes as follows:
Gershon uses different levels of Bloom’s Taxonomy to define the all/most/some outcomes.
Alternatively, you can select a keyword from one of the top two levels of the taxonomy and then modify these to create increasingly complex learning objectives.
Another technique Gershon suggests is to divide the taxonomy into sections. For example, he splits the levels of the cognitive domain into three sections: remember and understand, apply and analyze, and evaluate and create. Then, he divides the lesson into three segments and focuses on one of the three sections of the domains in that lesson segment.
To implement Gershon’s technique, divide your lesson into three segments. Assign “remember and understand” to the first segment, “apply and analyze” to the second segment, and “evaluate and create” to the third segment of the lesson.
Below are example activities that can be used for each section of the lesson:
Section One: Remember and Understand
Section Two: Apply and Analyze
Section Three: Evaluate and Create
Alternatively, Crowe et al (2008) divide Bloom’s taxonomy into two sections referred to as lower order cognitive skills (LOCS) and higher order cognitive skills (HOCS) to better align assessments with learning activities in college-level Biology classes. LOCS comprise the first three cognitive levels of Bloom’s Taxonomy (remember, understand, and apply) whereas HOCS include the second three levels (analyze, evaluate, and create).
