Now that you know about percentile rankings, it’s helpful to know what the ACT’s percentiles are, both for composite scores and individual subject area scores.
You can use the following score chart to find percentile rankings for your overall ACT composite score and for each section (English, Math, Reading, and Science).
To find your percentile, first find your score between 1 and 36 on the left-hand side, and then slide over to the correct subject area or composite to see your percentile ranking. For example, a composite score of 30 has a 95th percentile ranking, but a Reading section score of 30 has a 90th percentile ranking.
Here's the most recent data from the ACT:
