ACT Score Guide: How Scoring and the Composite Work
Understand ACT scoring. How each section becomes a 1 to 36, the EMR Composite on the redesigned ACT, the STEM score, superscoring, and what a good score means.
By James L., Test Prep Specialist
The direct answer: each ACT® section is scored on the 1 to 36 scale, and your Composite is the average of your English, math, and reading scores on the redesigned ACT. Science and writing are optional. If you take science you also receive a STEM score, and if you take writing you receive an ELA score. ACT also offers superscoring, which averages your best section results across test dates. This guide explains the scale, the Composite change, superscoring, and what a "good" score means for admissions.

ACT Scoring at a Glance
| Category | Details |
|---|---|
| Scale | 1 to 36 per section, maintained on the redesigned ACT. |
| Composite | Average of English, math, reading (EMR). |
| Optional science | Separate science score plus a STEM score if taken. |
| Optional writing | Separate ELA score if taken. |
| Superscoring | Average of your best section scores across dates. |
| Benchmark | Colleges set their own targets. None is universal. |
How a Section Score Is Made
Your raw score is the number of correct answers. There is no penalty for guessing, so never leave a bubble blank. ACT converts that raw count to the 1 to 36 scale through a process that keeps scores comparable across test forms. ACT states it kept the legacy 1 to 36 scale on the redesigned ACT so scores stay consistent year to year (ACT scoring and the 1 to 36 scale).
No wrong answer penalty
Because blanks and wrong answers score the same, an informed guess on the four choice redesigned ACT is always better than nothing. This is why pacing and elimination matter as much as knowledge. A student who guesses on three questions they cannot solve loses nothing, while a student who leaves them blank forfeits free chances.
The Composite Changed in 2025
On the redesigned ACT, the Composite is based on English, math, and reading only. ACT moved to this EMR calculation for all students from September 2025. Before that, the Composite used all four sections (ACT's official test information). The practical effect: your reading score now weighs more, and science cannot pull the Composite down.
What happens to science
If you take the optional science section, you still receive an individual science score and a STEM score, which combines math and science. Colleges that want to see science will look at those, not the Composite.
What happens to writing
The optional writing essay yields an ELA score when taken. Most colleges do not require it, so check each school's policy before registering.
Superscoring Explained
A superscore is the average of your best section scores from different test dates. ACT says starting with the April 2025 online administration, superscores use English, math, and reading, with the same transition to September 2025 for all students (ACT scores page). In plain terms, if you score 28 English in April and 30 math in July, your superscore can use the 28 and the 30.
Why it changes your plan
Superscoring rewards focused retakes. You can sit once to lift English, again to lift math, and let the best stand. Instead of chasing one perfect test day, you collect your best section from each attempt. This is why most students improve on a second or third sitting.
What Is a Good Score
"Good" is relative to the colleges you target. There is no universal bar. A score that clears a safety school's median may miss a reach school's. The honest move is to look up each school's published middle 50 percent range, the band of scores for the middle half of admitted students.
Use it as a retake rule
If your score already sits at or above a school's median, retaking has diminishing returns. If you are below, a focused section push can help. The decision is per school, not per test.
Pair with GPA context
Admissions couples test scores with GPA. A 30 ACT with a 4.0 tells a different story than a 30 with a 2.5, and readers read them together. Your score is one signal among several.
Common Misconceptions
- "Science is in my Composite." Not on the redesigned ACT. It is optional and separate.
- "A wrong answer costs points." There is no guessing penalty.
- "One test defines me." Superscoring rewards your best section across dates.
- "The scale changed." It stayed 1 to 36.
- "STEM score equals Composite." It is separate, from science plus math.
A Worked Example: Building a Superscore
Concrete numbers make the system clear. Suppose your two sittings are:
- April: English 26, math 24, reading 23. Composite = (26 + 24 + 23) divided by 3 = 24.3, reported 24.
- July: English 25, math 28, reading 24. Composite = (25 + 28 + 24) divided by 3 = 25.7, reported 26.
Your superscore takes the best of each: English 26 (April), math 28 (July), reading 24 (July). That averages (26 + 28 + 24) divided by 3 = 26. A college using superscores sees 26, higher than either single sitting.
The science caveat
If you also sat science, your STEM score comes from the best math and best science across dates, reported separately. It does not change the EMR Composite above.
Your Score Review Checklist
- Pull each section score from every sitting you have.
- Compute the single sitting Composite for each date.
- Take the best English, best math, best reading across dates and average them.
- Compare that superscore to each school's published middle 50 percent.
- If you are at or above a school's median, retaking has diminishing returns.
- Keep the science and STEM scores separate. They matter only where colleges ask for them.
Test Day and After: Using the Score
The score only helps if you act on it. A clear routine turns a number into a plan.
- After the test, pull each section score and compute the single sitting Composite.
- Build your superscore from the best English, math, and reading across dates.
- Compare that number to each school's published middle 50 percent, not to a friend's total.
- If you are at or above a school's median, a retake has diminishing returns. Spend time on essays instead.
- If you are below, attack the single weakest section.
- Keep the science and STEM scores separate. They matter only where colleges ask for them.
Frequently Asked Questions
What is the ACT scale?
Each section scores 1 to 36, maintained on the redesigned ACT (ACT scoring and the 1 to 36 scale).
What is the Composite now?
The average of English, math, and reading, from September 2025 (ACT's official test information).
What is superscoring?
The average of your best section scores across test dates, using English, math, and reading.
Does science affect my Composite?
No. It is optional and reported separately with a STEM score.
Is there a penalty for wrong answers?
No, so guess rather than leave blanks.
What is a good ACT score?
It depends on the colleges you target. Compare your score to each school's published middle 50 percent range.
