The ACT produces a composite score on a 1-36 scale. That composite is the average of four section scores: English, Math, Reading, and Science. Each section is also scored on a 1-36 scale. According to ACT Inc.'s official score reporting system, ACT now reports two composite versions: the legacy composite uses the average of all four sections ((E+M+R+S)/4), while the enhanced composite uses three sections only ((E+M+R)/3), with Science reported separately as part of a STEM score. Check with your target colleges to confirm which version they accept.
Your raw score in each section is the total number of questions you answered correctly. There is no penalty for wrong answers on the ACT. Blank answers guarantee zero. On a four-choice question, a random guess gives you a 25% chance of a point.
ACT Inc. converts raw scores to scaled scores through a process called equating. The conversion table shifts slightly between test forms to account for difficulty differences. A 28 in English on one test date represents the same ability level as a 28 on another, even if the two forms had different question sets. This is why two students can get different numbers of questions right and still land at the same scaled score.
The optional ACT Writing test is scored separately on a 2-12 scale. It does not affect your composite. Most colleges that require writing evaluate it independently. The official ACT preparation guide includes a full-length practice test with scoring instructions and is the most reliable place to check current section structure before test day.
Your composite score is the average of your four section scores, rounded to the nearest whole number. A 26 in English, 28 in Math, 24 in Reading, and 30 in Science produces a 27 composite.
Score conversion tables are approximations. ACT Inc. releases the official conversion chart for each test form after the exam. Exact scaled scores vary slightly between administrations. For a breakdown of which ACT topics appear most often by section, our one-on-one ACT tutoring page covers the highest-yield content areas by question frequency.
The ACT allows calculators on the Math section only. You cannot use a calculator on English, Reading, or Science. No exceptions.
This is the biggest practical difference between ACT calculator policy and Digital SAT calculator policy. The Digital SAT built Desmos directly into its testing app for all Math questions. The paper ACT does not have a built-in calculator of any kind. You bring your own approved device, or you go without one.
What calculators are allowed on the ACT?
ACT Inc. publishes a full list of permitted and prohibited calculators. The general rule is: four-function, scientific, and graphing calculators are allowed, provided they do not have a built-in computer algebra system (CAS) that simplifies symbolic expressions. Prohibited models include the TI-89 Titanium, TI-Nspire CX CAS, HP Prime, and Casio ClassPad series. If your calculator has a CAS, leave it at home. Modifications are also regulated: tape must be removed, sounds must be off, infrared ports must be covered, and power cords must be removed before entering the test room.

What is the best calculator for the ACT?
The TI-84 Plus CE is the best calculator for the ACT. It handles graphing, statistics, matrices, and basic trigonometry. Most high school students already own one. If you're deciding between a TI-84 Plus and a TI-84 Plus CE, the CE is lighter and has a colour screen that makes graphs easier to read under test conditions.
Bring a backup calculator and fresh batteries. If your calculator malfunctions during the test, proctors do not provide replacements. Our one-on-one ACT tutoring sessions include calculator-specific drills so students know exactly which functions to use and how fast to access them.
Does the ACT have Desmos?
It depends on whether you're taking the paper or digital ACT. The digital ACT, available through ACT's online testing platform, includes a built-in Desmos graphing calculator for the Math section, along with digital scratch paper and accessibility tools. The paper ACT does not have any built-in calculator.
If you're registered for the paper-based ACT, you must bring your own approved handheld. If you're taking the digital ACT, Desmos will be available in the testing interface, but you may still bring a backup handheld calculator. Check your test registration confirmation to confirm which format applies to your session.
An ACT superscore is now calculated from three sections: English, Math, and Reading. As of ACT Inc.'s updated reporting policy, Science is no longer included in the superscore composite. Your superscore is the average of your best English, Math, and Reading scores across all test sittings, rounded to the nearest whole number.
Example:
The superscore (30) is higher than either single-sitting composite. This is why superscoring often changes application strategy for students who are strong in some sections but inconsistent across others. Science now feeds into a separate STEM score that some programmes review independently.
Uju has worked with 60+ students on ACT prep at NAT for over 5 years. Students consistently describe her sessions as "the first time the test actually clicked." We asked her about the state average confusion she sees in families. Here is how she puts it:
See Uju's full tutor profile for her background and the score improvement patterns she's seen across hundreds of ACT sessions.
Not every college accepts superscores. Always verify with each school directly or check its Common Data Set. The ACT-SAT concordance tables also include guidance on how superscores translate to equivalent SAT composites for schools that report both.
Your ACT percentile tells you the percentage of test-takers who scored at or below your composite. According to the ACT National Ranks report, which uses a norming sample of 2023-2025 graduates, the mean ACT composite is 19.2. A composite of 24 reaches roughly the 74th percentile. A 30 puts you at approximately the 93rd percentile.
Percentile rankings matter because admissions offices compare your score to their enrolled student body, not the national average. A 29 composite, while strong nationally, may sit below the 25th percentile at a highly selective school.
ACT score percentile table (2025-2026 norms)
To understand how your percentile translates to real admissions outcomes, our post on Ivy League ACT score requirements maps specific composites to the 25th and 75th percentile ranges at Harvard, Yale, Princeton, MIT, and the other Ivy League schools.
A good ACT score is the score your target schools want to see. The national average is 19.2. Statistically, any composite above 24 is above average. But for admissions purposes, the benchmark that actually matters is your target school's middle 50% ACT range.
To be competitive, your composite should be at or above the school's 25th percentile. Scoring above the 75th percentile strengthens your application considerably. Scoring below the 25th percentile is not a disqualifier, but other parts of your application need to carry more weight.
ACT Inc. also publishes College Readiness Benchmarks that represent the minimum scores associated with a 50% chance of earning a B or better (and a 75% chance of a C or better) in related first-year college courses. The benchmarks are: English 18, Math 22, Reading 22, and Science 23. The methodology behind these benchmarks, based on data from 98 institutions and more than 90,000 students, is detailed in the ACT College Readiness Benchmarks technical report. A composite at or above these thresholds indicates basic college readiness. Most four-year programmes expect scores materially above them for admission.
Research from the Brookings Institution on universal ACT testing and Education Next on statewide ACT access both identify a composite of 20 as a practical floor for college readiness, with meaningful gains in four-year enrollment rates appearing above that threshold.
ACT score requirements by university tier
Data compiled from individual institutions' Common Data Set disclosures, 2023-2024 cycle.
A score alone doesn't determine admission. Our article on what Ivy League admissions really weighs explains how test scores interact with GPA, essays, and extracurriculars in selective admissions decisions.
Most students focus entirely on composite. That's correct for most applications, but some programmes weight specific section scores more heavily.
Engineering programmes at schools like Georgia Tech and Carnegie Mellon pay close attention to Math. Pre-med tracks at schools that require ACT sometimes scrutinise Science separately. Programmes with strong humanities emphases look closely at English and Reading.
NAT tutor Kurtis has scored both a 36 on the ACT and a 1570 on the SAT. Over 5 years of one-on-one sessions with 112+ students, he has heard every variation of score section anxiety a parent can bring to an intake call. We asked him what he tells families who fixate on the national average. His take:
The three-section rule: why most ACT score gains come from one section
NAT tutors have worked with hundreds of students who retake the ACT chasing a higher composite. The pattern we see consistently: students who spread prep effort equally across all four sections rarely improve by more than 1 composite point. Students who concentrate 70% of their prep time on their single weakest section improve by an average of 2-3 composite points in 8-10 weeks.
Here's why. Composite score is an average of four sections rounded to the nearest whole number. A 3-point gain in one section (from a 26 to a 29) moves your composite by less than 1 full point on its own. A 3-point gain in your weakest section plus a 1-point gain in your second-weakest section produces a 1-point composite jump. But a 4-point gain concentrated entirely in one section moves your composite by 1 full point and improves your superscore potential across future test dates.
The most common mistake we see: a student with a 26 English, 30 Math, 27 Reading, and 28 Science studies Math because they like it. Math is already their strength. Improving from 30 to 32 in Math yields less composite movement than improving from 26 to 30 in English. Section selection, not total study hours, determines how much a composite moves.
Your score today is a data point. It is not a verdict.
The most useful question is not "is my score good enough?" It's "how far am I from my target school's 25th percentile ACT range?" That gap tells you how much work is actually required.
A well-structured prep plan can close a 3-4 composite point gap in 8-12 weeks. Most students who plateau are not studying the wrong amount. They're studying the wrong things.
Here is a practical three-step approach:
Find your gap. Use the university match table above to see where your composite sits against your target schools' 25th percentile ranges. If you're within 3-4 points of a school's 25th percentile, you're in the improvable zone.
Diagnose before you drill. Doing more practice tests without knowing why you're missing questions doesn't close the gap. A diagnostic session with an NAT tutor identifies whether your score loss is content-based (gaps in specific topics), strategic (time misallocation between question types), or process-based (pacing, question misreads, careless errors in familiar material).
Build a targeted plan. A free ACT score review with an NAT tutor gives you a specific breakdown of which topics and question types are costing you the most points, and a prep plan that addresses those first.
If you've taken both the ACT and SAT, our ACT to SAT score conversion chart helps you compare your results directly. The official equivalence tables are also published jointly by ACT Inc. and the College Board in the ACT-SAT concordance PDF, based on a study of 589,753 students with documented correlations of 0.885 for Math and 0.884 for Reading/Writing. Some students score materially higher on one test than the other, and knowing which to submit can change your application profile. Our Digital SAT Score Calculator runs the same raw-to-scaled conversion for the Digital SAT if you want to compare results side by side.
NAT tutors have taken the ACT. Every tutor scored in the 99th percentile on their own exam and graduated from a top-15 university. Tutors including Kurtis Lee (36 ACT, 1570 SAT, Duke), Uju (35 ACT, 1590 SAT, Northwestern), and Frances (35 ACT, Yale) bring session-specific, pattern-based tutoring that goes beyond what any prep book or algorithm can offer.
Research from the Brookings Institution on test prep effectiveness shows that private tutoring consistently outperforms self-study, but access and cost create gaps in who benefits. NAT addresses the access gap by matching students directly with tutors who have taken the exact test their student is preparing for.
The approach NAT uses is the sinking-ship method: identify exactly which question types and skill areas are pulling the score down, fix them systematically, and confirm the fix with practice data before test day. There are no long-term contracts and no group sessions. Every session is one-on-one, built around the student's specific score gaps and test timeline.
92% of NAT students improve by 3 or more ACT composite points. Read our success stories to see how students have closed 4-composite-point gaps in 10 weeks using targeted, section-specific prep with an NAT tutor.

FAQ’s
Frequently Asked Questions
How is the ACT composite score calculated?
The ACT composite score is the average of your four section scores (English, Math, Reading, and Science), each scored on a 1-36 scale. The four section scores are added together and divided by four, then rounded to the nearest whole number. ACT Inc. also now reports an enhanced composite using only English, Math, and Reading ((E+M+R)/3), with Science reported separately as a STEM score. The optional Writing test produces a separate 2-12 score that does not affect the composite.
What is a good ACT score?
A good ACT score depends on your target schools. The national average is 19.2. A score above 24 is above average nationally. For selective universities, the competitive threshold is typically 30 or above. For Ivy League schools, most enrolled students score between 34 and 36. ACT's College Readiness Benchmarks set minimum expectations at English 18, Math 22, Reading 22, and Science 23 for basic college readiness.
Can you use a calculator on the ACT?
You can use an approved calculator on the ACT Math section only. The paper ACT does not provide a built-in calculator. Students must bring their own approved handheld device. The TI-84 Plus CE is the most widely used choice. The digital ACT includes a built-in Desmos graphing calculator. Phones, tablets, laptops, smartwatches, and calculators with CAS functions are not allowed on either format. See the full ACT calculator policy for the complete approved and prohibited list.

ACT superscoring is now calculated from three sections: English, Math, and Reading. Your superscore is the average of your best English, Math, and Reading scores across all ACT sittings, rounded to the nearest whole number. Science is no longer included in the superscore composite. See the ACT superscore FAQ for full details. Many selective colleges accept superscores, but policies vary. Always confirm directly with each school.
How many times can you take the ACT?
ACT Inc. does not set a formal limit on how many times you can take the ACT. Most students take it two to four times. Some colleges note multiple attempts in applications, though there is no evidence this negatively affects admissions outcomes at most schools.
What is the highest ACT score possible?
The highest possible ACT score is 36 composite. A 36 requires a perfect or near-perfect score on all four sections. Fewer than 0.1% of test-takers score a 36.
