Predictive Validity

Core Concept

What is Predictive Validity?

Predictive validity is the extent to which a test accurately predicts future performance or outcomes related to the construct being measured. We examine how well current measurements forecast future achievements.

Purpose and Utility

1

Forecasting Utility

Determines if test scores are useful forecasts of future behaviour or achievements.
2

Selection Contexts

Valuable in selection contexts (e.g., employment, education).

Practical Examples

Predictive validity is commonly sought in high-stakes entry and hiring processes.

✓

Job Aptitude Test

An aptitude test given to job applicants that predicts future job performance demonstrates predictive validity.
✓

Academic Entrance Exams

College entrance exams predicting university success.

Assessment Methodology

The methodology requires comparing the initial measure to the future outcome.

Current Test Score ↔ Criterion Measure (Future)
Involves correlating test scores with future criterion measures collected after some time interval.

Validity Benchmark

💡

Correlation Strength: Higher correlation indicates stronger predictive validity. Look for a significant positive relationship between the initial test and the future outcome.
