Validity is best described as...

• A. The consistency of test results across forms
• B. The degree to which evidence and theory support the interpretations of test scores entitled by the proposed tests
• C. The speed of test administration
• D. The fairness of scoring

Answer: (B)

Validity means the extent to which the interpretations of test scores are supported by evidence and theory for the test’s intended use. It’s about whether the test actually measures what it’s supposed to measure and whether the score meanings justify the decisions you’ll make from them. Different kinds of evidence help establish this: content validity checks if items cover the intended domain; criterion-related validity looks at how scores relate to other relevant measures or outcomes; and construct validity gathers evidence that the test truly taps the intended construct. Keep in mind that reliability is a separate idea—the test can give consistent results without necessarily providing valid interpretations for a given purpose. Fairness of scoring matters too, but validity specifically focuses on whether the score interpretations and uses are justified by evidence and theory.
