EPPP Score Converter

The EPPP is scored on a scaled system from 200 to 800. Most jurisdictions require a scaled score of 500 to pass. This tool estimates the raw percentage needed based on historical ASPPB equating formulas.

Estimated Scaled Score

Assumptions: Uses a simplified linear equating model where 70% raw equals 500 scaled. Actual ASPPB scoring uses complex Item Response Theory (IRT) where questions are weighted differently based on difficulty.
