In addition to your final composite score, you'll also receive an SAT percentile rank. A percentile rank indicates the percentage of students with scores equal to or lower than your score, who also took the SAT in the past three graduating classes. For example, if you score in the 85th percentile, 85% of the comparison group achieved the same score or lower than you – higher scores equal higher percentiles. This information is helpful when researching schools because schools will often show a preference for students who rank in a high percentile on their SATs.
