The degree to which the content of a test is representative of the domain it's supposed to cover is known as?

• A. Face validity
• B. Content validity
• C. Concurrent validity
• D. Predictive validity

Answer: (B)

Content validity is about how well the test items cover the entire domain they’re meant to assess. It means the items collectively map onto the construct’s full range of content, so they sample the knowledge, skills, or behaviors that define the domain. Typically this is established through expert review and a careful specification of the content domain to ensure no important areas are omitted and no irrelevant items are included. This differs from appearance-based judgments of validity (face validity), which only consider whether the test looks like it measures what it should, not whether it truly represents the domain. It also differs from how well the test relates to other measures or future outcomes (concurrent and predictive validity), which are about relationships with external criteria rather than coverage of the content itself.
