How the ACT Is Scored: the 1–36 Composite

A clear walk-through of ACT scoring: the four 1–36 section scores, how the Composite is averaged and rounded, where Science and the essay fit, and when scores arrive.

Each core ACT section — English, Math and Reading — is scored 1–36, and your Composite is simply their average, rounded to the nearest whole number. Science, if you take it, is reported on its own 1–36 scale and forms a separate STEM score with Math; it does not count toward the Composite. The optional essay has its own scale. There's no wrong-answer penalty, and scores usually post about 2–4 weeks after the test.

The math behind it

From section scores to one Composite

Three numbers go in; one Composite comes out. Here's exactly how the average works.

What to know

Three scoring rules that change your strategy

Understanding how points are counted tells you where to spend effort — and what never to do.

Rounding

Every core section pulls equal weight.

Because the Composite is a simple average of three scores, raising your weakest core section moves the Composite as much as raising your strongest. Balance, then push your best.

No penalty

Always bubble in an answer.

Wrong answers and blanks count the same — zero. Even a random guess on a question you skip has a one-in-four chance, so fill in every bubble before time is called.

Separate scores

Science and the essay stand apart.

Science is its own 1–36 score (and feeds a STEM score with Math); the essay sits on its own scale. Neither changes your Composite, so plan them around what your colleges actually want.

When scores arrive

Roughly two to four weeks

After test day, multiple-choice scores — your section scores and Composite — typically post online about 2 to 4 weeks later, though some test dates take a little longer. If you took the optional essay, that score can lag the multiple-choice results by additional days. You'll also see your percentile ranks, which show how your scores compare with other recent test-takers. All timing and percentile figures are approximate and shift by administration — confirm on act.org.

Quick scoring checklist

  • Composite = average of English, Math, Reading, rounded.
  • Science is separate; it also forms a STEM score with Math.
  • The essay has its own scale and never touches the Composite.
  • No wrong-answer penalty — answer every single question.
  • Expect scores roughly 2–4 weeks after the test date.
FAQ

ACT scoring questions

How is the ACT Composite calculated?
The Composite is the average of your three core section scores — English, Math and Reading — each on a 1–36 scale, rounded to the nearest whole number. Science, if you take it, does not count toward the Composite. For example, scores of 28, 30 and 26 average to 28.
What is a STEM score on the ACT?
The STEM score is a reported average of your Math and Science section scores, on the same 1–36 scale. It is informational and separate from your Composite; some STEM-focused programs look at it. You only get one if you take the optional Science section.
Is there a penalty for wrong answers on the ACT?
No. The ACT has no wrong-answer penalty — your score is based only on the number of questions you answer correctly. Because blanks and wrong answers count the same, you should answer every question, even when you have to guess.
How is the ACT essay scored?
The optional Writing essay is scored on its own scale — approximately 2–12 — by readers across several writing domains, and is reported separately. It is not part of your 1–36 Composite and does not change it. Confirm the current essay scale on act.org.
How long does it take to get ACT scores?
Multiple-choice scores typically post online about 2 to 4 weeks after your test date, sometimes a little longer; essay scores can take additional time. Exact timing varies by test date — confirm on act.org.
