The TRL learning system also supports Bloom’s Taxonomy of Learning. Bloom’s taxonomy delineates six distinct levels of knowledge acquisition within the cognitive domain, and identifies the attributes associated with each of the learning levels referenced.

The TRL learning system is focused on the first three levels of Bloom’s Taxonomy: knowledge, comprehension, and application, which build the gateway skills for learning any subject.

Benjamin Bloom created this taxonomy for categorizing levels of abstraction of questions that commonly occur in educational settings.

The taxonomy provides a useful structure in which to categorize test assessment questions.

Educators will characteristically ask questions associated with the particular
levels delineated by the taxonomy.

Evaluation is the highest level in Bloom’s Taxonomy and involves reviewing evidence, facts, and ideas, then making appropriate judgments.

Synthesis involves putting together ideas and knowledge in a new way. This is where innovations truly take place.

Analysis means breaking apart information and ideas into their component parts: dissect the subject matter, explain how the parts fit together, find gaps in your understanding, and seek additional information.

Application means using what you know in a concrete (real life) situation. This is the third stage TRL addresses.
