PreACT Score Calculator
The PreACT is ACT’s official practice test. Most students take it in 10th grade, and a shorter PreACT 8/9 exists for grades 8 and 9. It follows the real ACT closely, so your score gives you an honest early look at where you stand and which subjects need work.
Type your section scores into the calculator above to get your composite. Because PreACT scoring recently changed, the calculator lets you pick the old or the new formula. Your official score always comes from your school’s score report. This is an unofficial estimator and isn’t affiliated with or endorsed by ACT, Inc.

Old vs. New PreACT Scoring: Which One Applies to You?
The PreACT is being redesigned to match the Enhanced ACT, and the biggest change is how the composite is calculated.
New scoring (fall 2026 onward): Your composite is the average of English, Math, and Reading only. Science becomes optional and is reported separately, so it no longer raises or lowers your composite. PreACT Secure and PreACT 9 Secure moved to the new blueprint in spring 2026.
Old scoring (earlier test dates): Your composite averaged all four sections: English, Math, Reading, and Science.
If you aren’t sure which one you got, look at the header of your score report or ask your school counselor. If you tested before fall 2026, use the old formula.
How to Calculate Your PreACT Composite
Each section gets a scale score. The standard PreACT runs from 1 to 35, and the PreACT 8/9 runs from 1 to 30.
New formula:
Composite = (English + Math + Reading) ÷ 3
Old formula:
Composite = (English + Math + Reading + Science) ÷ 4
Your STEM score, which appears on the report, is the average of your Math and Science scores: (Math + Science) ÷ 2.
Worked example
Say your scores are English 20, Math 22, Reading 21, Science 19.
- New formula: (20 + 22 + 21) ÷ 3 = 63 ÷ 3 = 21
- Old formula: (20 + 22 + 21 + 19) ÷ 4 = 82 ÷ 4 = 20.5, which rounds to 21
- STEM score: (22 + 19) ÷ 2 = 20.5, which rounds to 21
Here both formulas land on the same number. That’s common, but not guaranteed. If your Science score is much higher or lower than the rest, the two composites can end up a point or more apart.
How Is a PreACT Scored? From Raw Score to Scale Score
You get one raw point for every question you answer correctly. There’s no penalty for wrong answers, so never leave a question blank. Your raw score for each section is then converted to a scale score, and the conversion is slightly different on every test form. That’s why a raw-score guess can be off, and why this calculator asks for scale scores from your report.
PreACT Percentiles: How Do You Compare?
The average PreACT composite is around 16. The 90th percentile is roughly 22 on the standard PreACT and about 23 on the PreACT 8/9.
Keep in mind that the two tests are ranked separately. A 20 earned by a 9th grader on the PreACT 8/9 doesn’t mean the same thing as a 20 earned by a 10th grader on the standard PreACT. Compare yourself only to students who took your version.
What Is a Good PreACT Score?
The PreACT is practice, so “good” depends on where you’re headed rather than on one magic number. Three ways to judge your score:
- Against your grade level. A 9th grader and an 11th grader aren’t expected to score the same.
- Against the College Readiness Benchmarks. Your report shows which subjects already meet ACT’s benchmark for entry-level college courses and which don’t. This is more useful than the composite alone.
- As a starting line. The real value is having a baseline to improve from over the next year or two.
If a section is below the benchmark, that’s information, not a verdict. It simply tells you where your study time will pay off most.
Estimating Your ACT Score From Your PreACT
A rough rule of thumb is to add about one point to your PreACT composite to guess your future ACT composite. Please treat that as a ballpark only. It isn’t a validated conversion.
Real results vary a lot because:
- You’ll keep learning between the two tests, and the extra coursework shows up in your score.
- Practice and test familiarity usually matter more than any fixed point adjustment.
- Some students jump far more than one point, and some barely move, depending on how much they prepare.
A better way to use the PreACT is to find your weakest section and plan your prep around it.
PreACT vs. PreACT 8/9 vs. PreACT Secure
These names get mixed up a lot, but they’re different tests.
- PreACT: the standard version, usually taken by 10th graders at school.
- PreACT 8/9: a shorter version for grades 8 and 9, scored on a lower scale (1–30).
- PreACT Secure and PreACT 9 Secure: online versions used for higher-stakes purposes, such as some state or district testing and, in some cities, selective high school admissions.
Your score report names the exact test, and that tells you which scale and formula apply to you.
Frequently Asked Questions
How many questions are on the PreACT?
It depends on your version and on whether your school has moved to the new design. The older four-section PreACT had roughly 130 to 140 questions. Your school counselor or score report will give the exact numbers for your test.
Does Science count toward my PreACT composite?
Under the new scoring, no. The composite uses English, Math, and Reading only, and Science is optional and reported separately. If you took the PreACT before the change, Science was included in the average.
What is a good PreACT score for a freshman? For a sophomore?
There’s no single cutoff. Compare your section scores to the College Readiness Benchmarks on your report and to the percentiles for your own test version.
How accurate is a PreACT to ACT conversion?
Only roughly. Adding about one point is a common estimate, but your actual ACT score depends on how much you prepare and grow in between.
What’s the difference between PreACT and PreACT 8/9?
PreACT is for 10th graders and scored from 1 to 35. PreACT 8/9 is shorter, meant for grades 8 and 9, and scored from 1 to 30.
Is this PreACT calculator official?
No. It’s an unofficial estimator built from publicly available scoring information. Your school’s score report is the only official result.
