Introduction
When your child’s ACT scores post in MyACT, the first thing you see is a Composite and a score for each section (1–36), along with a Superscore (if applicable). Each score’s percentile, which ACT labels US Rank, appears in the Detailed Results section. Depending on what your child took, that detailed report may also show STEM, ELA, and Writing scores.
This is Matter’s parent guide to what each number means and which ones actually matter. For the full orientation, start at our ACT Resource Hub.

ACT Scores
The MyACT summary shows your Superscore (if applicable) and single-test results. Each block lists Composite and section scores (each ranging 1–36), and a link to “View Score Details.”
Writing (ranging 2–12), if taken, appears as its own item and can read “Pending” until scored.

The Composite is the average of only English, Math, and Reading. The Superscore takes the best English, Math, and Reading scores across all test dates and averages them.
Percentiles can be viewed by clicking “View Score Details.” This section lists Your Score, a US Rank (the percentage of recent US students who scored at or below that score), and more.

STEM is the average of the Math and Science scores, shown only when Science is taken. If Writing is taken, an ELA score (English, Reading, Writing) and a Writing score on the 2–12 scale appear too, each with its own rank.
This score details report also breaks each section into categories (e.g. Algebra, Functions, Geometry, etc.). These flag strengths and weaknesses within a section and provide valuable insight on where your student has room to improve.
Illustrative example. Actual ACT score reports differ, and the numbers shown are fictional.
What you receive after the test
Scores are posted online in your child’s MyACT account, not mailed. ACT publishes a specific initial score-release date for each test date on its test dates schedule. Online results typically post a few days before paper results. Multiple-choice scores are reported within 2 to 8 weeks and Writing within 5 to 8 weeks. An optional My Answer Key is also available, so students can see which items they missed.
The scores at a glance
Composite (1–36): the average of English, Math, and Reading, rounded.
Section scores (1–36 each): English, Math, and Reading, plus Science if taken.
STEM (1–36): the average of Math and Science, shown only if Science is taken.
ELA (1–36): the average of English, Reading, and Writing, shown only if Writing is taken. ACT converts your Writing (2–12) score to a hidden 1–36 score before averaging.
Writing (2–12): the rounded average of four essay domains.
The Composite and section scores
Colleges look primarily at the Composite score which ranges from 1 to 36. It is the average of the English, Math, and Reading scores, rounded to the nearest whole number (e.g. 32.33 rounds down to 32, and 32.67 rounds up to 33).
Each of the three core sections is scored 1 to 36. If your child takes optional Science, it is reported as a standalone 1–36 score that does not enter the Composite (this is a change from the old ACT). For the full picture of what shifted, see our guide to the enhanced ACT.
There is no penalty for guessing, so students should answer every question.
STEM, ELA, and Writing scores
Two combined scores appear only when your child takes the matching optional section:
STEM: the average of the Math and Science scores. It appears only if Science is taken.
ELA: the average of the English, Reading, and Writing scores. ACT converts the reported 2–12 score into a hidden 1–36 score for this average. ELA appears only if Writing is taken.
Writing scores are the rounded average of four domain scores (2–12): Ideas and Analysis, Development and Support, Organization, and Language Use and Conventions. The Writing score does not affect the Composite.
Percentiles and National Ranks
Every score has a percentile, which ACT labels US Rank. It is not on the MyACT summary screen your child first sees. You can find it by clicking “View Score Details.” A percentile reflects the percentage of test-takers who scored at or below your score. A Composite at the 80th percentile means your child scored as well as or better than 80 percent of the comparison group.
ACT bases the current ranks on the graduating classes of 2023, 2024, and 2025 and applies them to tests taken September 2025 through August 2026 (ACT National Ranks).
How superscoring works
If your child tests more than once, ACT takes the highest English, Math, and Reading scores from across all your child’s test dates and averages them into a Superscore composite, which can exceed any individual sitting.
ACT calculates and provides the Superscore, but individual colleges decide whether to use it. Checking your target colleges’ Superscore policies can help you decide how many times to test.
What’s a “good” ACT score?
Matter perspective: There is no ACT “cutoff.” ACT reports the Composite, section scores, and percentiles, but it does not publish per-college target scores. What counts as a strong score depends entirely on the colleges your child is targeting and expectations vary widely from school to school.
In our experience, the useful question is not “what is a good ACT score” but “what Composite keeps my child competitive at their specific target schools.” Check each college’s own admissions or class profile page for the middle 50 percent ACT range of admitted students, and compare your child’s Composite against that.
Common questions about ACT scores
When will scores come out? ACT publishes a specific initial release date for each test date on its test-dates schedule. Multiple-choice scores usually post within two to eight weeks, and online results a few days before paper.
Is there a penalty for guessing? No. The ACT is scored on the number of correct answers, with no deduction for wrong ones so students should answer every question.
Does the Science score affect the Composite? No. Since the enhanced ACT was introduced in 2025, Science is reported as a standalone 1–36 score outside the Composite.
What is an ACT Superscore, exactly? Your child’s best section scores across multiple test dates, combined by ACT into one Composite superscore. Each college has their own policy on whether to use it.
Can we fix an error on the report? Students can request score verification up to 12 months after the test date. A $67 fee applies and is refunded if an error is found.
Where do we view and send scores? You’ll find these scores in your child’s MyACT account, where you can also send them to colleges as recipients.
Knowing what the numbers mean is one thing. Knowing what each section tested to produce them is another. For that and the full set of guides, return to the ACT Resource Hub.
