PSAT Scoring and Average Scores PSAT scores are reported on a scale that runs from 20 to 80, 20 being the lowest and 80 the highest. This is a parallel to the SAT, which scores between 200 and 800 on each test part.
The new SAT, on the other hand, will have a range of 200 to 800 for each section and a range of 400 to 1600 for your composite score. Your PSAT scores help predict your SAT scores, but the scale is shifted slightly lower to account for the fact that the PSAT is an easier test than the SAT.
