The extent to which a test score predicts future performance in a relevant area.

Explanation:
Predictive validity is about how well a test score forecasts future performance in a relevant area. This matters when a test is used to choose people or anticipate how they’ll perform later, because a stronger link between scores and future outcomes shows the test is truly useful for predicting what matters. It’s typically measured by correlating test results with a criterion judged in the future; a higher correlation indicates better predictive validity. This concept is distinct from reliability, which is about consistency, and from broad validity, which covers all aspects of whether a test measures what it’s supposed to measure.
