ACT Superscore Calculator

Calculate your ACT superscore from multiple test dates

Enter your English, Math, Reading, and Science scores from up to four ACT test dates; the tool takes the highest section from any date and averages them to compute your best possible ACT superscore composite.

What is an ACT superscore?

A superscore is a new composite built from your best score in each section across all the dates you tested, rather than the best single sitting. The four highest section scores are averaged and rounded to give a composite from 1 to 36.

If you have taken the ACT more than once, a superscore combines your best section results across all dates into a single, higher composite. This calculator does that math for up to four test dates, picking your strongest English, Math, Reading, and Science scores and averaging them.

How it works

For each of the four sections, the tool scans every test date you entered and keeps the highest score. It then averages those four bests and rounds to the nearest whole number:

superscore = round( (bestEnglish + bestMath + bestReading + bestScience) / 4 )

Rounding uses standard half-up rounding, so an average of 28.5 becomes a composite of 29. Each section is treated independently, which is why a superscore can never be lower than your best single sitting.

Example and tips

Suppose date one is 30 English, 26 Math, 28 Reading, 24 Science (composite 27), and date two is 27, 31, 25, 29 (composite 28). The superscore takes 30, 31, 28, and 29, averaging to 29.5, which rounds to 30 — better than either single date. Confirm each college accepts superscores, and consider retaking only the sections where you have the most room to improve.
