“Education must be increasingly concerned about the fullest development of all children and youth, and it will be the responsibility of the schools to seek learning conditions which will enable each individual to reach the highest
level of learning possible.”

Benjamin Bloom Handbook on Formative and Summative Evaluation of Student Learning


Bloom’s original taxonomy (developed in the 1950's) divided the way people learn into three domains: cognitive, affective, and psychomotor.

In the 1990's Lorin Anderson, a former student of Bloom revised the original cognitive domain. The original Bloom's taxonomy is still relevant, but under the new revisions the six major categories of the cognitive domain were changed from noun to verb format and some subcategories were reorganized.

The revised taxonomy is preferred by some educators as a more authentic tool for curriculum planning, instructional delivery, and assessment. Many educators also believe that the newer taxonomy is more applicable to all levels of schooling and better aligned to the 21st Century Skills we are seeking to instill in our students. In an effort to address the needs of all educators, I have included information on this site that will give you an opportunity to work with the original cognitive categories as well as the revised cognitive domain categories. Use the tabs found at the top of the page to explore the various domains and the levels identified by Bloom and his colleagues.
