Which type of validity is primarily assessed by expert judgment regarding test content?

Content validity is assessed by expert judgment regarding test content because it focuses on the extent to which a test measures what it is intended to measure. In this context, experts evaluate whether the items in the test are representative of the construct being assessed. This involves examining whether the test includes sufficient and relevant content to cover the topic at hand, ensuring that the assessment is comprehensive and appropriate for its intended use.

Experts typically have a deep understanding of the subject matter and can provide insights into whether the test content aligns well with the intended constructs. This judgment is crucial for validating that the test effectively captures the essence of the variable or construct being measured, thereby reinforcing its credibility and relevance in practice.
