content validity

the extent to which a test measures a representative sample of the subject matter or behavior under investigation. For example, if a test is designed to survey arithmetic skills at a third-grade level, content validity indicates how well it represents the range of arithmetic operations possible at that level. Modern approaches to determining content validity involve the use of exploratory factor analysis and other multivariate statistical procedures.
