What is the ACT?

The ACT (American College Testing) is a standardized test used for college admissions in the United States. Administered by ACT, Inc., the test measures high school academic achievement and college readiness across four core areas: English, Mathematics, Reading, and Science.

First introduced in 1959 as a competitor to the SAT, the ACT has grown to become equally accepted by all U.S. colleges and universities. In recent years, the ACT has been taken by approximately 1.3 million students annually, making it one of the most important factors in college admissions decisions.

The test is offered seven times per year in the U.S. (September, October, December, February, April, June, and July) at designated testing centers. Students can also take the ACT online at certain locations.

ACT test structure

The ACT consists of four multiple-choice sections and an optional writing test:

SectionQuestionsTimeContent
English7545 minGrammar, punctuation, sentence structure, rhetorical skills
Math6060 minPre-algebra through trigonometry, no calculator section
Reading4035 minReading comprehension across four passage types
Science4035 minData interpretation, research summaries, conflicting viewpoints
Writing (Optional)1 essay40 minArgumentative essay on a given prompt

The total testing time is 2 hours and 55 minutes without the writing section, or 3 hours and 35 minutes with writing.

How ACT scoring works

The ACT uses a two-step scoring process to convert your performance into a final score.

Raw scores

Your raw score is simply the number of questions you answer correctly on each section. There is no penalty for wrong answers, so you should answer every question even if you need to guess.

  • English: 0-75 raw points
  • Math: 0-60 raw points
  • Reading: 0-40 raw points
  • Science: 0-40 raw points

Scaled scores

Raw scores are converted to scaled scores ranging from 1-36 for each section. This conversion process, called "equating," adjusts for slight variations in difficulty between different test dates, ensuring that a 30 on one test date represents the same ability level as a 30 on another date.

The conversion varies slightly from test to test, but the general pattern remains consistent. For example:

  • Getting all questions correct typically yields a 36
  • Missing just a few questions might still yield a 35 or 36
  • The middle range (18-24) has the most room for raw score variation

Composite score

Your composite score is the average of your four section scores, rounded to the nearest whole number. For example:

Composite=English+Math+Reading+Science4\text{Composite} = \frac{\text{English} + \text{Math} + \text{Reading} + \text{Science}}{4}

If your section scores are 28, 26, 30, and 28:

Composite=28+26+30+284=1124=28\begin{aligned} \text{Composite} &= \frac{28 + 26 + 30 + 28}{4} \\[0.5em] &= \frac{112}{4} = 28 \end{aligned}

ACT percentiles

Your percentile rank indicates the percentage of test-takers who scored at or below your score. Higher percentiles are more competitive:

Composite ScorePercentileInterpretation
3699+Top 1% of all test-takers
33-3598-99Highly competitive for elite universities
30-3293-97Competitive for selective universities
27-2983-90Above average, competitive for many schools
24-2668-79Average to above average
21-2349-62Average range
18-2029-42Below average
Below 18Below 29May limit college options

The national average ACT composite score is approximately 20-21, though this varies slightly from year to year.

College readiness benchmarks

ACT establishes College Readiness Benchmarks—minimum scores that indicate a 50% chance of earning a B or higher in corresponding first-year college courses:

SubjectBenchmarkCollege Course
English18English Composition
Math22College Algebra
Reading22Social Sciences
Science23Biology

Meeting these benchmarks suggests you're prepared for college-level work in that subject area. Students who meet all four benchmarks have a strong foundation for college success.

Score goals by college selectivity

Different colleges have different expectations for ACT scores. Here are typical ranges:

Highly selective universities (Top 20)

  • Target composite: 33-36
  • Examples: Ivy League, Stanford, MIT, Duke
  • Students in the 99th percentile have the strongest applications

Selective universities (Top 50)

  • Target composite: 30-33
  • Examples: UCLA, University of Michigan, NYU
  • 90th percentile and above is competitive

Competitive state universities

  • Target composite: 25-30
  • Examples: Penn State, University of Texas, Ohio State
  • Above-average scores strengthen applications

Less selective institutions

  • Target composite: 20-25
  • Many state schools and smaller colleges accept scores in this range
  • Meeting the national average is generally sufficient

Superscoring

Many colleges practice "superscoring," which means they consider only your highest section scores across multiple test dates. For example:

Test 1Test 2Superscore
English282628
Math242727
Reading302830
Science262929
Composite272829

If a college superscores, taking the ACT multiple times can improve your reported score even if your overall composite doesn't increase.

Strategies to improve your score

General test-taking tips

  1. Answer every question — No penalty for guessing means leaving blanks is never optimal
  2. Pace yourself — Know how much time you have per question in each section
  3. Process of elimination — Narrow down choices before guessing
  4. Read questions carefully — Many wrong answers come from misreading

Section-specific strategies

English:

  • Read the entire sentence before selecting an answer
  • "No change" is correct about 25% of the time
  • When in doubt, choose the most concise answer
  • Watch for subject-verb agreement and pronoun errors

Math:

  • Use your calculator strategically but don't over-rely on it
  • Plug in answer choices when stuck
  • Draw diagrams for geometry problems
  • Know the common formulas (they're not provided)

Reading:

  • Read the passage first, then answer questions
  • Focus on main ideas and author's purpose
  • Don't spend too long on any single question
  • Return to the passage to verify answers

Science:

  • You don't need to know science facts—it's about data interpretation
  • Focus on the figures, tables, and graphs
  • Read conflicting viewpoints passages carefully
  • Don't get bogged down in scientific jargon

ACT vs. SAT

Both tests are accepted equally by colleges, but they have different characteristics:

Sections4 + optional writing2 (Reading/Writing combined)
ScienceDedicated sectionIntegrated into other sections
MathCalculator allowed throughoutCalculator and no-calculator sections
TimingFaster pacedSlightly more time per question
Scoring1-36 composite400-1600 total

Some students perform better on one test than the other. Consider taking practice tests for both to see which format suits you better.

When to take the ACT

Most students take the ACT for the first time in the spring of junior year. This timing allows for:

  • Completing most relevant coursework (especially math through Algebra II)
  • Time to retake if needed in fall of senior year
  • Meeting early application deadlines

A typical testing timeline:

  • Fall junior year: Take diagnostic practice test
  • Winter junior year: Focused preparation
  • Spring junior year: First official ACT
  • Summer: Review results and continue prep if needed
  • Fall senior year: Final attempt if improving

Sending scores to colleges

When you register for the ACT, you can select up to four colleges to receive your scores for free. Additional score reports cost $18 each.

Key points about score reporting:

  • Most colleges accept self-reported scores for applications
  • Official scores are required upon enrollment
  • Some colleges require all scores; others allow score choice
  • Check each college's policy before sending

Frequently asked questions

How many times can I take the ACT?

You can take the ACT up to 12 times total, though most students take it 2-3 times. There's no penalty for multiple attempts, and many colleges only consider your highest scores.

Do wrong answers count against me?

No. Unlike some older standardized tests, the ACT has no penalty for wrong answers. Always guess rather than leave a question blank.

Should I take the writing section?

Check the requirements of your target colleges. Many no longer require it, but some still do. When in doubt, take it—it's better to have a score you don't need than to need one you don't have.

How long are ACT scores valid?

ACT scores are valid for five years. Colleges will accept scores from tests taken during high school.

Can I use a calculator on the ACT?

Yes, calculators are permitted on the entire math section. However, certain types (those with computer algebra systems, like the TI-89) are prohibited. Check ACT's official calculator policy before test day.

What's a good score?

A "good" score depends on your target colleges. For most students, scoring above the national average (21) is a reasonable goal. For selective colleges, aim for scores in the 28-32+ range. For highly selective schools, 33+ puts you in a competitive position.
