Which term defines the degree to which a test specifically measures what it is intended to measure?

The term that defines the degree to which a test specifically measures what it is intended to measure is validity. Validity refers to the extent to which a test accurately reflects the concept or construct it is designed to assess. In the context of fitness assessments, for example, if a test is intended to measure cardiovascular endurance, it must effectively capture that variable rather than other unrelated factors.

When we assess validity, we look at various types such as content validity, criterion-related validity, and construct validity, which further refine our understanding of how well the test meets its intended purpose. A valid test ensures that the conclusions drawn from its results are sound and applicable to the intended population or condition.

In comparison to the other terms, reliability relates to the consistency of a test's results over repeated administrations, accuracy refers to how closely results align with the true value or benchmark, and feasibility relates to the practicality of implementing the test. While all these concepts are important in the context of assessments, validity is specifically focused on the relevance and appropriateness of the measurements being taken.
