Work out a superscore

How an ACT superscore is worked out

Average the best, then round.

The worked example: the best of each test, averagedBest English30AprilBest math31JuneBest reading30FebruaryComposite3091 ÷ 3 = 30.33, roundedThe worked example: the best of each test, averagedBest English30AprilBest math31JuneBest reading30FebruaryComposite3091 ÷ 3 = 30.33, rounded
Each test is taken at its best across the three dates; the three are averaged and rounded. No single sitting reached 30: the best was 29.

The arithmetic

Each ACT test is scored from 1 to 36. The composite is the average of the tests that count, rounded to the nearest whole number, with .5 rounding up. On the ACT given from 2025 the composite counts English, math and reading, and science is optional and reported on its own; on the earlier format all four tests counted. A superscore averages the best score in each test from any sitting.

Policies differ by college

Some colleges superscore the ACT, some use only the highest composite from one date, and some do not require scores. When your sittings span both formats, a college may treat them differently; its admission testing page says which rule it uses.

  2. ACT. The enhanced ACT (act.org, 2025): English, math and reading make up the composite; science is optional.
  3. ACT. Superscoring (act.org): the superscore as the average of your best test scores across attempts.
  4. College Board BigFuture and college admission pages: colleges set their own superscore and test-optional policies.
