Which concept explains that a test measures what it is supposed to measure?

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

Answer: (A)

Content validity focuses on whether the test items accurately represent the content domain it’s meant to assess. In other words, it asks if the questions sample the right material so the test truly covers what it’s supposed to measure. When a test aligns well with the curriculum or domain it targets, it’s demonstrating content validity, showing it measures the intended content rather than something else. Reliability is about consistency, construct validity about the underlying trait being measured, and face validity is about appearance at first glance, which doesn’t guarantee actual measurement accuracy. So this choice best captures the idea of measuring what it’s supposed to measure through proper content coverage.
