Content validity coverage check – UGC NET Question

Content validity concerns whether the items in a test or questionnaire are representative of the entire domain of content they are supposed to measure, such as a course syllabus or topic area. Subject experts often review the instrument to judge whether important areas are adequately sampled. High content validity reduces the chance that important facets of the construct are omitted. Therefore, the coverage-focused validity described in the stem is correctly called content validity.

Option A:
Option A, content validity, is especially important in achievement tests where missing topics can bias scores. When an instrument aligns well with specified learning outcomes or a blueprint, it demonstrates strong content validity, matching the stem exactly.

Option B:
Construct validity addresses whether the instrument truly measures the underlying theoretical construct, based on patterns of relationships with other variables and factor structure. It goes beyond simple content coverage, so it is not the best fit for this question.

Option C:
Criterion-related validity evaluates how well test scores correlate with an external criterion, such as job performance or future grades. It deals with predictive or concurrent accuracy rather than domain coverage. Hence, it is not appropriate here.

Option D:
Face validity refers to the extent to which a test appears to measure what it claims to, based on superficial inspection by users. It does not involve systematic analysis of content coverage, so it is not the correct answer.
