ACT Score Calculator 2026
Enter how many questions you answered correctly in each ACT section to estimate your section scores (1 to 36 each) and composite score (1 to 36). The calculator uses approximate raw-to-scaled score conversion curves based on released ACT practice test data and shows your estimated national percentile alongside your composite.
Fill in all four sections above to see your estimated ACT composite score.
Score estimates use approximate ACT conversion curves. Actual scores vary by test form and administration.
How the ACT Is Scored
The ACT has four required sections: English (75 questions), Math (60 questions), Reading (40 questions), and Science (40 questions). Each section is scored independently on a scale of 1 to 36. Your raw score for each section is simply the number of questions you answer correctly. There is no penalty for wrong answers, so guessing always makes sense when you are unsure.
The raw score is then converted to a scaled score using a scoring table that ACT releases with each test form. This conversion accounts for small differences in question difficulty between test forms so that a 28 on one form reflects the same level of performance as a 28 on another form, even if the raw scores required were slightly different.
The composite score is the average of your four section scores, rounded to the nearest whole number. Section scores and composite scores all fall on the same 1 to 36 scale. There are no sub-scores or cross-section scores that affect the composite on the standard ACT.
ACT Score Percentiles: What Your Score Means Nationally
An ACT composite score tells you how you performed on the test, but a percentile tells you how that performance compares to other test-takers nationally. The average ACT composite across all test-takers is approximately 20 to 21, which sits around the 50th percentile.
| ACT Composite | Percentile | Rating | College Context |
|---|---|---|---|
| 33–36 | 98th to 99th+ | Exceptional | Competitive at Ivy League and top-20 schools |
| 28–32 | 88th to 97th | Competitive | Strong at most selective universities |
| 24–27 | 71st to 87th | Strong | Above average, competitive at many four-year schools |
| 20–23 | 46th to 65th | Average | Near the national average |
| 14–19 | 12th to 40th | Below Average | May need improvement for selective admissions |
| 1–13 | Below 12th | Low | Significant preparation recommended |
Percentiles shift slightly year to year as the test-taking population changes. The values above reflect approximate national averages based on recent College Board and ACT score release data.
What Each ACT Section Tests
Understanding what each section measures helps you target your preparation more efficiently and interpret your section scores in context.
The English section (75 questions, 45 minutes) tests grammar, punctuation, sentence structure, and rhetorical skills. Questions are embedded in passages and ask you to identify errors or improve phrasing. Strong English scores come from knowing the most common grammar rules and being able to work quickly through five passages.
The Math section (60 questions, 60 minutes) covers pre-algebra, elementary algebra, intermediate algebra, coordinate geometry, plane geometry, and trigonometry. Unlike the SAT, the ACT Math section tests a broader range of topics and moves through them more quickly. Calculators are permitted for the full section.
The Reading section (40 questions, 35 minutes) tests passage comprehension across literary narrative, social science, humanities, and natural science passages. Time management is one of the biggest challenges on this section because students have under one minute per question after accounting for reading time.
The Science section (40 questions, 35 minutes) does not require advanced science knowledge. It primarily tests data interpretation, the ability to read graphs and tables, and understanding of experimental design. Students who are comfortable interpreting data and charts can do well on this section even without strong science content knowledge.
How to Improve Your ACT Score
Targeted preparation is more effective than general studying for the ACT because each section tests a specific and identifiable set of skills. The most useful starting point is a full-length timed practice test to identify which sections and question types are costing you the most points.
For most students, the English section offers the quickest score gains because the grammar rules being tested are finite and repeatable. Learning the 15 to 20 most commonly tested grammar patterns and practicing them across multiple passages can raise an English section score by several points relatively quickly.
Reading and Science scores improve most with practice on time management and passage strategy. Developing a consistent approach to each passage type rather than reading every word at full speed is what helps most students stop running out of time. Practicing with a timer from the start is important.
Math requires content review for most students. Identifying which topic areas are weakest and drilling those specifically before practicing mixed sets is more efficient than working through every problem type in order.
Frequently Asked Questions
How is the ACT composite score calculated?
The composite is the average of your four section scores (English, Math, Reading, Science), rounded to the nearest whole number. Each section is scored 1 to 36. The composite is also 1 to 36.
What is a good ACT score?
The national average is around 20 to 21. A score of 24 or higher is above the 70th percentile. Highly selective colleges typically see admitted students with composites of 33 to 36. What is good depends on the schools you are targeting.
How many questions are on the ACT?
215 questions across four sections: English (75), Math (60), Reading (40), and Science (40). There is also an optional essay that does not affect your composite score.
Is there a penalty for guessing on the ACT?
No. The ACT scores only correct answers. Wrong answers do not reduce your score. Always guess rather than leaving any question blank.
How does the ACT raw score convert to a scaled score?
Your raw score is the number of correct answers per section. That number maps to a scaled score of 1 to 36 using a conversion table that adjusts for test form difficulty. The conversion varies slightly by test form, which is why this calculator uses approximate curves.
What ACT score do I need for a full scholarship?
Thresholds vary by school and scholarship. Merit scholarships at many state universities start around 25 to 28. Competitive full-ride scholarships often require 32 or higher. Check each scholarship's eligibility requirements directly.
Should I take the ACT or the SAT?
Both are accepted at essentially all US colleges. The ACT includes a Science section, tests a broader math range, and moves faster per question. Taking a full practice test for each is the most reliable way to find which format suits you better.
How long does it take to receive ACT scores?
Multiple-choice scores are typically available online 2 to 8 weeks after test day. Writing scores, if taken, arrive 2 to 3 weeks after the multiple-choice scores.
