How ACT figures the multiple-choice test scores and the Composite score
- First we count the number of questions on each test that you answered correctly. We do not deduct any points for incorrect answers. (There is no penalty for guessing.)
- Then we convert your raw scores (number of correct answers on each test) to "scale scores." Scale scores have the same meaning for all the different forms of the ACT, no matter which test date a test was taken.
- Your Composite score and each test score (English, Mathematics, Reading, Science) range from 1 (low) to 36 (high). The Composite Score is the average of your four test scores, rounded to the nearest whole number. Fractions less than one-half are rounded down; fractions one-half or more are rounded up.
- We compute your seven subscores (Usage/Mechanics, Rhetorical Skills, etc.) in the same way, but subscores range from 1 (low) to 18 (high). There is no direct, arithmetic relationship between your subscores and your test scores—this means your subscores don't add up to your test score.
