ACT superscore calculator and retake planner

Your ACT superscore is the average of your best English, math and reading scores across every ACT you have taken, rounded to the nearest whole number. ACT calculates it for you once you have tested more than once. Science is not part of it, and each college decides whether it uses superscores.

How ACT builds your superscore

Four rules, each in act.org’s own words. The planner follows all four.

And you do not have to ask for it:

“ACT automatically calculates a Superscore for students who have tested more than once since September 2016.”

For Writing, STEM, ELA and how sending works, read the full guide: ACT superscore on the Enhanced ACT.

Science and the superscore

“The Superscore Composite now includes only English, Math, and Reading. Science is no longer part of the Composite calculation.”

act.org, ACT Superscore FAQs, read October 30, 2026.

Your best Science score still shows on your superscore report with the date you earned it, and act.org says it is combined with math for your STEM score. That is why the planner lists Science but leaves it out of the number.

How the right-answer estimate works

ACT turns right answers into a 1 to 36 section score with a conversion table, and every test form gets its own table. The planner uses the practice scale inside Prep36: the curve from an official released Enhanced ACT practice form, stretched across every question in each section. It counts from the bottom of your current score band, so it leans toward more questions, not fewer. Read every number as plus or minus a point, and as a direction, not a promise.

One rule from act.org makes every one of those questions worth an answer:

“Your scores will be based only on the number of questions that you answer correctly; there is no penalty for guessing.”
