Predictive Validity

Predictive validity refers to the extent to which a test or assessment accurately predicts future performance or outcomes. In language testing, predictive validity is important for determining whether a test can reliably forecast a learner's ability to perform well in future language-related tasks or contexts, such as academic success or job performance. High predictive validity means that the test results are a good indicator of the skills and knowledge that will be required in real-world situations. Ensuring predictive validity involves correlating test scores with relevant future criteria and outcomes.
