Which term describes whether an assessment actually measures the intended construct?

• A. Validity
• B. Equity
• C. Reliability
• D. Practicality

Answer: (A)

Validity is about whether the assessment measures what it’s actually intended to measure. If a test is designed to gauge a specific construct, like mathematical problem-solving, validity asks whether the items really tap that construct rather than something else (for example, reading speed or general test-taking skill). A valid test yields scores that meaningfully reflect the intended ability, and the evidence supports that interpretation for the intended use. There are nuances, such as content validity (do the items cover the domain?), construct validity (do the scores relate to other measures of the same construct as expected?), and criterion validity (do scores predict relevant outcomes). If a test ends up measuring something different, its validity is compromised, even if it’s reliable or easy to administer. Equity, reliability, and practicality describe fairness, consistency, and feasibility, respectively, and don’t directly answer whether the test measures the intended construct.
