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.
Raw scores are then converted to scaled scores ranging between 160 and 760 (760 is the highest possible score for each section). The raw scores are added together for the total PSAT score, or Selection Index, which ranges between 320 and 1520.Unlike the SAT, the PSAT does not contain a scored essay portion. However, the College Board will provide high schools with the option of administering a practice essay portion, called ScoreWrite.SAT/NMSQTÂ® is a trademark jointly owned by the College Board and the National Merit Scholarship Corporation, which were not involved in the production of, and does not endorse this product.
