Which type of validity refers to how well a test predicts future performance?

• A. Content validity
• B. Construct validity
• C. Criterion-related validity
• D. Predictive validity

Answer: (D)

Predictive validity refers specifically to the extent to which a test accurately forecasts future performance or outcomes. This type of validity is crucial in testing scenarios where the purpose is to assess how well test results can be used to predict an individual's success in a certain context, such as education, employment, or other fields. For example, college entrance exams often aim to predict students' future academic performance based on their scores.

The other types of validity serve different purposes. Content validity focuses on how well a test measures the specific content it is intended to assess, ensuring it covers the subject matter comprehensively. Construct validity examines whether a test truly measures the theoretical construct it claims to measure, which can include traits or abilities. Criterion-related validity, while related to predictive validity, is broader and encompasses both predictive and concurrent validity, assessing how well one measure correlates with another established measure at the same time. However, in this particular context, it is predictive validity that directly correlates with predicting future performance.
