Summary
This paper analyzes the semantics of test validity. First, a simple definition of validity is given: Test X is valid for the measurement of attribute Y, if and only if the proposition ‘Scores on test X measure attribute Y’ is true. We analyze the meaning of validity by examining the truth conditions of the proposition. These truth conditions depend on the interpretation of the term ‘measures’. Three measurement systems that may provide such an interpretation are examined: Fundamental measurement theory, classical test theory, and latent variable theory. It is argued that the semantics of validity depend on the choice of measurement system. Because there is no logically or empirically compelling argument for or against any particular theory, the meaning of validity is to a certain extent indeterminate.
