What term describes test material that serves as a reference to what cadets studied?

The term that best describes test material serving as a reference to what cadets studied is "relevant." Relevant materials are closely linked to the subject matter that has been taught, providing a direct connection to the concepts and skills learned during training. This ensures that assessments accurately reflect the knowledge and competencies that cadets are expected to demonstrate.

While terms like "valid," "reliable," and "current" are important in the context of assessments, they do not specifically capture the essence of referring directly to what cadets have studied. Valid refers to how well a test measures what it is supposed to measure; reliable denotes the consistency of a test's results over time; and current indicates information that is up-to-date. However, “relevant” encompasses the idea that the test material aligns well with the cadets' learning, making it the most appropriate choice.
