What Your ACT Composite Score Means

The ACT is scored 1–36 composite, averaging four sections: English, Math, Reading, and Science. The national average is approximately 19–20. A score of 30+ puts you in the top 7% of all test-takers.

34–36

99th percentile

Exceptional

Top 1–2% nationally. Competitive at the most selective institutions: Ivy League, MIT, Stanford, and other elite schools. This range represents near-perfect performance across all four sections.

30–33

93rd–97th percentile

Excellent

Top 7–9% nationally. Strong at most top-25 universities. At or above the 75th percentile for most Ivy League and near-Ivy schools. SAT equivalent: roughly 1400–1520.

24–29

74th–88th percentile

Good

Top 18–26% nationally. Competitive at flagship state universities and many selective private schools. At or above the 25th percentile for most top-50 schools.

18–23

38th–63rd percentile

Average

Around the national average. Competitive at many 4-year colleges. Consider whether test-optional strategy suits your target schools if you are below their 25th percentile.

Below 18

Below 38th percentile

Below Average

Below the national average. You are competitive at less selective institutions. Many schools with test-optional policies allow applications without a score in this range.

Full ACT Score Percentile Table

Percentiles show the percentage of test-takers who scored at or below each composite score. A 30 at the 93rd percentile means you scored higher than 93% of ACT test-takers. This table covers every whole-number score from 12 to 36.

Section Score Breakdown

Each of the four ACT sections is also scored 1–36. Section scores can reveal specific strengths and weaknesses that the composite obscures.

Section Score	English	Math	Reading	Science
36 (perfect)	Top 1%	Top 1%	Top 1%	Top 1%
33–35	Top 1–3%	Top 3–5%	Top 3–5%	Top 3–5%
30–32	Top 5–10%	Top 7–12%	Top 7–12%	Top 7–10%
27–29	Top 12–20%	Top 14–22%	Top 15–22%	Top 13–20%
24–26	Top 22–30%	Top 24–32%	Top 23–31%	Top 21–30%
20–23	Average range	Average range	Average range	Average range
Below 20	Below average	Below average	Below average	Below average

What each section score reveals

English (grammar, rhetoric): Measures usage, mechanics, and rhetorical skills. Strong signal for writing-intensive majors. Engineering programs care less; English programs care most.
Math (pre-algebra through pre-calc): STEM programs focus here. A Math of 34+ is expected for competitive CS, Engineering, and Math programs. Math is the most improvable section with targeted practice.
Reading (passage comprehension): Tests inference and critical reading. Closely tied to general academic aptitude. Social Sciences and Humanities programs weight this section.
Science (data interpretation): Does not test science content knowledge — tests data analysis and reasoning. Pre-med and life science applicants benefit from a strong Science score.

Very uneven section scores

A composite of 27 with English 20, Math 34, Reading 27, Science 27 is very different from 27 across all sections. Admissions offices note section variation. For programs with specific section requirements or areas of emphasis, very low section scores can be a concern even with a strong composite.

ACT STEM Score and ELA Score

Your score report also includes a STEM Score (average of Math + Science) and an ELA Score (average of English + Reading + Writing). These are composite sub-scores that some STEM programs and education programs use as quick references. A STEM Score of 30+ is strong for engineering; an ELA Score of 30+ is strong for humanities applications.

Performance Level Descriptors

ACT describes college readiness in terms of what students at each score range can typically do in academic settings:

Score Range	Level	ACT College Readiness Description
28–36	Well-prepared	High likelihood of success in first-year college courses. Meets college readiness benchmarks in all four areas.
24–27	Likely prepared	Likely to succeed in most first-year courses. Meets benchmark in most areas; may need support in one or two.
20–23	Somewhat prepared	50% likelihood of success in first-year college courses. May benefit from placement assessments.
16–19	Borderline	Below college-ready threshold. Many students in this range benefit from developmental coursework.
Below 16	Underprepared	Significant academic development needed before college-level coursework. Not meeting ACT college readiness benchmarks.

ACT College Readiness Benchmarks are the section scores associated with a 50% probability of earning a B or better in a corresponding college course: English 18, Math 22, Reading 22, Science 23. Meeting all four benchmarks is a strong indicator of college preparedness.

How to Interpret Your ACT Score Report

ACT sends your official score report through your ACT account and directly to score recipients you designate. Understanding each component helps you diagnose strengths and weaknesses.

Composite Score (1–36)

The average of your four section scores, rounded to the nearest whole number. This is the number colleges cite in their middle-50% ranges.

Section Scores (1–36 each)

English, Mathematics, Reading, and Science separately. These appear on all score reports. Some programs specifically request these.

STEM Score (1–36)

Average of Math and Science section scores. Useful reference for STEM program applicants and for evaluating science and mathematical reasoning.

ELA Score (1–36)

Average of English, Reading, and Writing (if taken). Useful reference for writing-intensive programs and education majors.

Progress Toward Career Readiness

ACT maps scores to career readiness indicators across skill areas. Useful for understanding real-world skill gaps, though colleges rarely use this component.

ACT Writing Score (2–12) — if taken

Scored separately from the composite. A small number of colleges still require the Writing section; most do not. Check requirements before registering.

Score Choice

You can choose which test sittings to send. ACT Score Choice lets you send only your best sitting. Superscoring (sending best section scores across sittings) is supported by many schools.

What Score Improvement Is Realistic?

Understanding realistic improvement helps you plan test prep timelines and retake decisions effectively.

Starting Composite	Typical 1st Retake Gain	After 6–8 Weeks Study	Max Realistic (3–4 months)
14–18	1–3 points	2–5 points	4–8 points
18–22	1–3 points	2–4 points	4–7 points
22–26	1–2 points	2–4 points	3–6 points
26–30	1–2 points	1–3 points	2–5 points
30–33	0–2 points	1–2 points	1–4 points
33–36	0–1 point	0–2 points	0–2 points (ceiling)

The ACT's tighter time pressure means time management training is often the biggest driver of improvement. Many students score 2–3 points higher simply by practicing pacing strategies. Science is the most improvable section with practice because it tests a learnable skill (data interpretation), not biology or chemistry knowledge.

Superscoring: Many universities now superscore the ACT, taking the best composite from multiple sittings or the best section scores across all attempts. Check each school's policy. If superscoring is accepted, you can focus each retake on your weakest section.

Grad School vs. Undergraduate Context

The ACT is used almost exclusively for undergraduate admissions at US colleges. Graduate programs use the GRE or GMAT. However, there are specific contexts where ACT scores are relevant beyond high school applications:

Undergraduate (Primary Use)

Accepted at all major US 4-year colleges and universities
Interchangeable with SAT at most schools
ACT Writing (optional) required at very few schools now
Superscoring accepted at many schools post-2020
State-day ACT (11th grade) in many US states is free
Military academy applications (West Point, etc.) accept ACT

Other Contexts

Gifted/talent search programs (e.g., Duke TIP) use ACT for middle schoolers
Merit scholarship programs at many state universities use ACT cutoffs
Some community college programs use ACT for placement decisions
National Merit Scholarship uses PSAT (SAT family); ACT equivalent is the National Merit Scholar Qualifying Test (NMSQT)
Residency programs (medicine) do not use ACT; MCAT is required

What Admissions Officers Actually Care About

For most selective schools, ACT composite is evaluated alongside GPA, course rigor, and other application components. A few important nuances:

Internal consistency: High composite with unusual section imbalance (e.g., 36 Science, 22 English) can raise questions. Both are noted.
Multiple test attempts: ACT is transparent — most universities see how many times you took the test. Multiple attempts are normal and not penalized.
ACT Writing (optional essay): Few schools still require the ACT Writing section. Check specific requirements before registering with or without it.
First-generation students: Admissions offices increasingly contextualize ACT scores within socioeconomic background. A 28 from a underfunded school district may be evaluated differently than a 28 from a prep school.
Concordance with SAT: Most admissions offices use concordance tables to compare ACT and SAT scores. An ACT of 30 is approximately equivalent to SAT 1360–1390.
