A: PeerPower is the exclusive provider of percentile scores for California, Virginia, Maryland, and Massachusetts. All states release the percentage of students who pass the test, but the percent who passed is not the same as a percentile score. Other states provide the average score for a test so you can know if you / your student is below, at, or above average. But percentile scores are better measures of whether your student is on track to be college and career ready.
