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.
240 is the highest possible score on the PSAT. Your score, indicating you are in the 76th percentile, means that you received a higher score than 76% of the people who took the PSAT. Anything indicating you did better than half of them would be great.
