Validity in testing refers to what?

• A. How well a test measures what it is supposed to
• B. How consistent the scores are
• C. The length of the test
• D. The test administration time

Answer: (A)

Validity is about whether the test actually measures what it is intended to measure and whether the resulting scores support the intended interpretations and decisions about a learner’s ability. In other words, does the content align with the skill or knowledge being assessed, and do the scores meaningfully reflect that construct? The other options describe reliability (consistency of scores), test length, and administration time—factors that affect practicality or consistency, not the truthfulness of what the test claims to assess. For example, a reading test that includes unrelated trivia would undermine validity because the scores wouldn’t accurately reflect reading comprehension. A well-designed test, by contrast, yields results that truly represent the targeted skill.
