Digital SAT Scoring Algorithm Explained: How Module 1 Mistakes Cap Your 1500

2026-09-06 5 min read
• Direct Answer / Key Takeaway

The Digital SAT uses Item Response Theory (IRT) where every question has an individual difficulty parameter. Missing an easy question in Module 1 penalizes your score more severely than missing a hard question in Module 2 because it damages your routing probability to the higher scoring curve.

Under College Board's new Item Response Theory (IRT) scoring engine, two students who both get 8 questions wrong can receive scores that differ by over 120 points.

Careless mistakes on easy Module 1 questions are devastating because they prevent you from accessing the top-tier scoring curve.
