Principles And Applications Of Assessment For Counseling Practice Test

Validity means the interpretations and uses of test scores are supported by evidence. Among the different forms, construct validity is the broadest framework because it brings together evidence from multiple sources—how well the content represents the construct, how the items relate to one another (internal structure), and how the test scores relate to other measures and theoretical expectations. This accumulation of diverse evidence across methods is what makes construct validity the most comprehensive way to demonstrate that a test measures the intended construct across its uses. While validity does involve measuring what you intend, that view is narrower; reliability is about consistency, not whether interpretations are warranted, and a test isn’t considered valid without the necessary supporting evidence.
