Benjamin Bloom proposed six hierarchical and cumulative levels of testing to measure different levels of student subject knowledge. A review of these levels would assist the business law teacher in developing tests to measure the desired level of student mastery of the subject. It might also prove to be a tool for the teacher to assist in instructional evaluation. The lowest of these levels is knowledge, the ability to remember material previously learned. This level is a prerequisite for all other levels as is each level to all higher levels. Comprehension is the next level, where one must go beyond knowledge by understanding what one knows. Application is the next highest level. At this level one must be able to apply what he/she has comprehended. Then comes analysis, in which the individual must be able to break down or separate into parts the knowledge comprehended and applied. At the higher level is synthesis, which requires the creative combination of knowledge analyze from several topics to create something which previously did not exist. Finally, evaluation, the highest level, requires critical appraisal of the knowledge one has analyzed and synthesized.
