If a test adequately samples the domain of knowledge it intends to assess, this is an example of which validity?

• A. Content validity
• B. Face validity
• C. Construct validity
• D. Criterion validity

Answer: (A)

This question is about how well a test reflects the actual domain of knowledge it’s meant to measure. When a test adequately samples the domain, the items collectively cover the full range of topics and skills that define that domain. That alignment—mapping items to the content that should be tested—is what content validity is all about. If the test really represents the intended content, instructors and researchers can trust that the scores reflect learners’ true knowledge of that domain. In contrast, face validity is about whether the test appears to measure what it’s supposed to on the surface, which isn’t a guarantee of actual measurement accuracy. Construct validity concerns whether the test truly measures the theoretical trait or ability and how its results relate to other measures of that trait. Criterion validity looks at how well the test scores relate to external performance criteria, such as future performance or parallel assessments.
