Predictive Validity

Predictive validity focuses on the extent to which scores on a measure are related to scores from a criterion measure they administered at a later time. It is a type of criterion-related validity. There are two forms of criterion-related validity: predictive validity and concurrent validity. Concurrent-based validity is based on the accuracy of a test’s ability to estimate performance on some other measure that could be taken at the same time, while predictive validity uses the scores from the new measure to predict performance on a criterion measure that is usually administered at a later time.

Examples of contexts where predictive validity is relevant include the following:

• Scores on a foreign language aptitude measure given at the beginning of an immersion course are used to predict scores ...
