Bloom's taxonomy is a set of three hierarchical models used for classification of educational learning objectives into levels of complexity and specificity. The three lists of Bloom’s Taxonomy cover the learning objectives in cognitive, affective and psychomotor domains. The cognitive domain list of Bloom’s Taxonomy has been the primary focus of most traditional education and is frequently used to structure curriculum learning objectives, assessments and activities.

The models of Bloom’s Taxonomy were named after Benjamin Bloom, who chaired the committee of educators that devised the taxonomy. He also edited the first volume of the standard text, Taxonomy of Educational Objectives: The Classification of Educational Goals.
