Content validity coverage of domain – UGC NET Question

Content validity refers to how well the items in a test or questionnaire sample the full range of the content domain or syllabus that is of interest. Expert judgment is typically used to check whether important topics, cognitive levels and skills are proportionately represented. High content validity indicates that decisions based on test scores are grounded in comprehensive coverage rather than in a narrow subset of material. Since the stem emphasises adequate representation of the entire content domain, content validity is the correct term.

Option A:
Predictive validity concerns the extent to which test scores can forecast future performance on a relevant criterion, such as success in a later course. While important, it does not address whether the items themselves cover the domain sufficiently. Hence, predictive validity does not match the description in the question.

Option B:
Concurrent validity evaluates the degree to which test scores correlate with other measures of the same construct taken at the same time, indicating how well the test aligns with existing indicators. It focuses on agreement with current criteria rather than on syllabus coverage, so it is not the correct completion.

Option C:
Construct validity deals with the theoretical meaning of the test scores and how they relate to broader concepts and other variables, not specifically with the breadth of content coverage. Therefore, construct validity is not appropriate for the stem, which stresses representation of the content domain.

Option D:
Content validity is often ensured by preparing a table of specifications that maps items to objectives and content areas. This process ensures that no critical topic area is neglected, which is exactly what the question is about.
