The Taxonomy of Educational Objectives aka Bloom's Taxonomy is a classification system created by college examiners and led by Dr. Benjamin Bloom in 1956. Its purpose was to classify educational objectives for test items that can be exchangeable among educators. There were many forces that inspire Bloom's epiphany at the American Psychology Association Convention of 1948 to gather with colleagues and propose the idea. Turns out, illiteracy was rampant at the beginning of World War II, and teacher shortages were high due to the need of workers to support the war effort.
