What is the term for the degree to which a test measures what it claims to measure?

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

Answer: (A)

Validity concerns whether a test measures what it’s supposed to measure. When a test is designed to assess a theoretical concept, the idea you’re checking is construct validity: does the test truly tap the intended construct? This differs from content validity, which looks at whether the test covers the relevant domain of tasks; reliability, which is about consistency of scores; and predictive validity, which concerns how well the test forecasts future outcomes. So, the degree to which the test measures the intended construct is construct validity.
