Which statement best defines validity in educational assessments?

• A. Reliability
• B. Validity refers to how accurately a test measures what it is intended to measure.
• C. Generalizability
• D. Consistency across items

Answer: (B)

Validity is the degree to which evidence supports the interpretations of test scores for their intended purpose. In other words, it asks whether the test actually measures the construct it claims to measure. This makes the statement the best definition because it centers on the accuracy of what the test assesses and the inferences drawn from the results. Reliability is about consistency of scores, not whether the test measures the right thing. Generalizability concerns applying findings to other groups or settings, not the accuracy of the measurement itself. So focusing on whether the test measures what it is supposed to measure captures the essential idea of validity.
