Which validity concerns whether a test instrument measures the entire content area it purports to measure?

• A. Internal Consistency
• B. Concurrent Validity
• C. Content Validity
• D. Predictive Validity

Answer: (C)

Content validity is about whether a test fully represents the content area it’s meant to assess. It asks if the items cover all the important topics and skills described in the intended domain, with tasks that reflect real-world expectations for the age group. For a preschool assessment, this means including items across language, early math, social-emotional development, and physical development as outlined by standards, not just a subset of topics. This focus helps ensure the test truly measures the intended content rather than a narrow slice. Internal consistency checks if the items relate to each other, concurrent validity compares the test to another measure at the same time, and predictive validity looks at how well scores predict future performance. These address different questions than coverage of the full content area.
