Predictive validity refers to what aspect of a test used in EC settings?

• A. The extent to which test results predict future real-life functioning.
• B. The degree of reliability over time.
• C. The cost-effectiveness of the test.
• D. The test's ability to measure only cognitive skills.

Answer: (B)

Predictive validity is about how well a test score forecasts future outcomes in real life. In early childhood settings, this means seeing whether a measurement taken now can predict later things like academic progress, classroom behavior, or functional skills as the child grows. The stronger the predictive validity, the more confident teachers and specialists can be that the assessment will provide useful information for planning interventions or supports.

Reliability over time, in contrast, asks whether the test yields consistent results if you administer it again or use a different form. It’s about consistency, not about forecasting. Cost-effectiveness relates to practicality and value, not accuracy of prediction. Measuring only cognitive skills touches on what the test covers or its construct, not its ability to predict future functioning.
