Enhanced ACT Score Calculator
Last updated: September 2026
The ACT changed format starting in 2025. Under the Enhanced ACT, three required sections (English, Math, and Reading) make up your composite, and Science is now optional and reported separately. This calculator follows the current format.
Enter your English, Math, and Reading results for a predicted composite, or add an optional Science result to see your separate STEM score.
Note: This is an unofficial estimator built from publicly available exam-format and scoring data. It is not produced or endorsed by ACT, Inc.
ACT Enhanced Score Calculator (New for 2026!)
Based on the most recent Exam Scoring Guidelines — these scores may not be 100% accurate
How to Use the Calculator
- Enter your raw score (questions answered correctly) for English, Math, and Reading.
- Each raw score is converted to a scaled score on the 1–36 scale.
- Your composite is the average of the three, rounded to the nearest whole number.
- If you took Science, enter it too to get a separate STEM score.
The raw-to-scale conversion shifts slightly from one test date to another, because ACT adjusts each form for small differences in difficulty. This calculator uses a representative conversion, so your official score could differ by a point or so.
What Changed: Enhanced ACT vs. Legacy ACT
| Legacy ACT | Enhanced ACT (current) | |
|---|---|---|
| Required sections | 4 (English, Math, Reading, Science) | 3 (English, Math, Reading) |
| Core questions | 215 | 131 |
| Core testing time | ~2 hr 55 min | ~2 hr 5 min |
| Science | Mandatory, counted in composite | Optional, reported separately |
| Composite | Average of all 4 sections | Average of English, Math, Reading |
| Math answer choices | 5 | 4 |
The rollout happened in phases. Online national testing switched in April 2025, national paper and digital testing followed by September 2025, and school-day and state administrations finished the transition by spring 2026. If you are using prep material published before 2025, assume it describes the legacy format.
Exam Format
| Section | Questions | Time | Counts toward composite? |
|---|---|---|---|
| English | 50 | 35 min | Yes |
| Math | 45 | 50 min | Yes |
| Reading | 36 | 40 min | Yes |
| Science (optional) | 40 | 40 min | No, reported separately |
Without Science, that is 131 questions in about 2 hours 5 minutes. With Science, it is 171 questions in about 2 hours 45 minutes.
There is no penalty for wrong answers, so answer every question. Math now has four choices instead of five, which makes a blind guess slightly more likely to land.
How the Composite and STEM Scores Work
Composite = (English + Math + Reading) ÷ 3, rounded to the nearest whole number.
Example: English 24, Math 27, Reading 25. (24 + 27 + 25) ÷ 3 = 25.33, so the composite is 25.
Science never counts toward the composite. If you take it, you also receive a STEM score:
STEM = (Math + Science) ÷ 2, rounded to the nearest whole number.
Example: With the same Math 27 and a Science score of 29, STEM = (27 + 29) ÷ 2 = 28. It appears next to your composite of 25, not inside it.
Approximate Raw Score Conversion
Official conversion tables are published only with specific official practice tests and change from form to form. This table shows the general shape of the curve, not a precise lookup:
| Approximate % correct | Typical scaled score |
|---|---|
| ~95%+ | 33–36 |
| ~80–94% | 27–32 |
| ~60–79% | 20–26 |
| ~40–59% | 14–19 |
| Below 40% | 1–13 |
How to Calculate Your ACT Superscore
Many colleges consider a superscore: your best section scores across all your test dates.
- Collect the score reports from every date you tested.
- Pick your highest English, highest Math, and highest Reading score. They can come from different dates.
- Average those three and round to the nearest whole number.
Example: Attempt 1 was English 24, Math 26, Reading 28. Attempt 2 was English 27, Math 23, Reading 26. Your best scores are English 27, Math 26, Reading 28. (27 + 26 + 28) ÷ 3 = 27, higher than either attempt’s own composite.
Legacy and Enhanced ACT scores can reportedly be combined into one superscore, so an older attempt isn’t wasted because the format changed. Science can be superscored separately if a college asks, but it stays outside the main three-section superscore. Not every college superscores, so check each school’s policy.
What Is a Good ACT Score?
The national average composite for recent graduating classes is around 19.4. Rough benchmarks:
- 18–20: near the median
- 23–24: above roughly the 70th–80th percentile, competitive for many state universities
- 28–30: around the 90th percentile and up, competitive for selective colleges and many merit scholarships
- 33+: elite, generally 99th percentile or higher
Percentiles come from a rolling multi-year sample and shift slightly each year, so use them as a compass, not a cutoff.
Should You Take the Optional Science Section?
Even though Science is outside the composite, some colleges, including some selective schools and most military academies, still require or recommend a Science score. Policies are school-specific and can change.
A simple rule of thumb: take it if you are aiming for a STEM major, applying to a school that asks for it, or you are strong in science and want the STEM score on your report. If none of that applies, skipping it saves time and lets you focus on the three required sections.
Common Mistakes When Estimating Your ACT Score
- Using old prep material. Anything from before 2025 may include the four-section composite or five-choice Math.
- Adding Science into the composite. It is not part of it anymore.
- Treating one practice test as your score. Scores vary, so take two or three before judging.
- Forgetting that superscore policies differ. Some colleges superscore, some don’t, and some want all scores.
- Skipping timing practice. The sections are fast, especially Math at 45 questions in 50 minutes.
Frequently Asked Questions
What is the Enhanced ACT, and how is it different?
It has three required sections instead of four, 131 core questions instead of 215, and an optional Science section with its own STEM score.
Does Science count toward my composite?
No. The composite is the average of English, Math, and Reading only.
What is the STEM score?
The average of your Math and Science scaled scores. It appears only if you took Science.
How is the superscore calculated?
Take your highest English, Math, and Reading scores across all dates, average them, and round to the nearest whole number.
Can I combine legacy and Enhanced ACT scores?
According to ACT’s guidance, yes. Confirm on ACT’s official site and with your target colleges.
What is a good composite score?
The national average is around 19.4. High 20s to low 30s are generally competitive for selective colleges, and 33+ is elite.
Is this calculator official?
No. It is an unofficial estimator, and your official score may differ because of form-to-form equating.
