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.
From section scores to one Composite
Three numbers go in; one Composite comes out. Here's exactly how the average works.
| Score | Scale | How it's built | In the Composite? |
|---|---|---|---|
| English | 1–36 | Raw correct answers, converted to a scaled score | Yes |
| Mathematics | 1–36 | Raw correct answers, converted to a scaled score | Yes |
| Reading | 1–36 | Raw correct answers, converted to a scaled score | Yes |
| Composite | 1–36 | Average of English, Math & Reading, rounded | — |
| Science (optional) | 1–36 | Scored like the core sections, reported on its own | No |
| STEM (if Science taken) | 1–36 | Average of Math and Science | No |
| Writing essay (optional) | ~2–12 | Reader scores across writing domains | No |
Three scoring rules that change your strategy
Understanding how points are counted tells you where to spend effort — and what never to do.
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.
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.
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.

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.
