What does content validity measure in selection tests?

• A. The reliability of test results across time.
• B. The extent to which a selection test measures the knowledge and abilities truly relevant to the job.
• C. The test's fairness across groups.
• D. The test's ability to predict long-term career success independent of the job.

Answer: (B)

Content validity measures how well the test content reflects the actual knowledge, skills, and abilities that the job requires. To establish it, you base the test on a thorough job analysis, involve subject-matter experts to review and approve items, and map each item to essential job tasks or competencies. This alignment ensures the test truly assesses what matters for job performance, rather than unrelated abilities. Reliability across time is about score consistency, not whether the content is job-relevant. Fairness across groups concerns potential bias or unequal impact on different groups, which is about equity rather than how representative the content is. Predicting long-term career success beyond the job focuses on broader outcomes and different types of validity (predictive/criterion-related validity) rather than how well the test content matches the job itself.
