Content Validity refers to the extent to which a test or measurement accurately represents the specific concept it aims to assess. It ensures that the items included in the test cover all relevant aspects of the subject matter, making it a crucial factor in evaluating the quality of assessments in fields like education and psychology. To establish Content Validity, experts often review the test items to determine if they align with the intended content. This process may involve creating a blueprint that outlines the key areas to be measured, ensuring that the test comprehensively reflects the construct being evaluated.
