Which type of test is typically written?

A knowledge-based test is primarily written because it is designed to assess a person's understanding of theories, concepts, and facts related to a particular subject. In the context of training like the Interservice Nonlethal Individual Weapons Instructor Course, this type of test evaluates the individual's grasp of knowledge necessary for instructing others and understanding nonlethal weaponry and tactics.

Knowledge-based tests usually consist of multiple-choice questions, true/false statements, or short answer questions that require the test-taker to reflect on the material learned during the course. Such tests are effective for measuring cognitive understanding, which is integral to mastering complex subjects.

Performance-based tests, in contrast, assess practical skills and the ability to apply knowledge in real-world scenarios, which isn't primarily gauged through written formats. Group tests might involve collaboration among participants and typically don't focus solely on individual written responses. Oral tests, while they can similarly gauge knowledge, rely on spoken responses rather than written format. Thus, the written format of a knowledge-based test is what makes it the appropriate choice for this question.
