Content validity is primarily evaluated by whom?
Psychometricians
The test takers
Subject matter experts
Government officials
The correct answer is: Subject matter experts
Content validity is primarily concerned with the extent to which a test measures what it is supposed to measure, and it focuses on the relevance and representativeness of the test content. Subject matter experts play a crucial role in evaluating content validity because they possess in-depth knowledge of the field or domain being tested. They ensure that the test items align with the theoretical constructs and that the content adequately covers the necessary knowledge and skills required for the specific purpose of the assessment. These experts analyze whether the items are appropriate and relevant to the construct being assessed, helping to establish that the test is indeed reflecting the area of interest. Their expertise allows them to judge if the test content is comprehensive and if it represents the characteristics of the population for which the test is intended. In contrast, psychometricians generally focus on statistical properties such as reliability and construct validity rather than the content itself. Test takers may provide feedback on their experiences with the test but do not have the specialized knowledge needed to assess content validity accurately. Government officials may oversee testing processes, but they are not typically involved in the specialized evaluation of the test content, which is best suited for subject matter experts.
