predictive validity

evidence that a test score or other measurement correlates with a variable that can only be assessed at some point after the test has been administered or the measurement made. For example, the predictive validity of a test designed to predict the onset of a disease would be strong if high test scores were associated with individuals who later developed that disease. It is one of three types of criterion validity. Also called predictive criterion-related validity; prospective validity. See also concurrent validity; retrospective validity.
