Adequacy
A test is a systematic procedure for measuring an individual's behavior that follows specific guidelines to formally and systematically gather information about learners. For a test to be adequate, it must be sufficient for its intended purpose of measuring the knowledge and skills pupils have acquired. However, a test maker should not assume their instrument can measure all a pupil has learned, so they construct test items to representatively sample from the content areas based on a test blueprint to determine educational outcomes. A good test includes items covering different areas of the material assigned and the entire syllabus.
