What Is the ACT? Format, Scores, and How the Test Works (2026)
By Makon AI Team · Updated July 15, 2026
The ACT is a standardized college-readiness test used for purposes that can include admission, scholarships, course placement, and academic planning. The current enhanced ACT has three core multiple-choice sections—English, Math, and Reading—with Science and Writing available as optional sections in national testing. State and district programs can make different contract-level choices about Science and Writing.
ACT reports section scores on a 1–36 scale. Since September 2025, the ACT Composite is calculated from English, Math, and Reading rather than from four sections. A student who takes optional Science still receives a college-reportable Science score and can receive a STEM score; optional Writing is reported separately and does not change the Composite.
Current ACT section structure
ACT’s official section page lists this standard-time design:
| Section | Questions | Time | Main focus |
|---|---|---|---|
| English | 50 | 35 minutes | Grammar, usage, organization, and rhetoric |
| Math | 45 | 50 minutes | Mathematical reasoning through trigonometry |
| Reading | 36 | 40 minutes | Comprehension and analysis |
| Science (optional) | 40 | 40 minutes | Data interpretation and scientific reasoning |
| Writing (optional) | 1 essay | 40 minutes | Developing and supporting a position |
Some questions are field-test items and are not scored, but students are not told which ones. Treat every question as scored.
Use ACT’s official test-section page for the current blueprint. Students testing with approved accommodations may have different timing or break arrangements.
What the English section asks you to do
English questions appear within passages and test decisions about sentence structure, punctuation, usage, style, organization, and rhetorical effectiveness.
Example:
The museum extended its hours, it expected more evening visitors.
The text contains two independent clauses. A comma alone creates a comma splice. Valid repairs include a period, semicolon, or comma plus a coordinating conjunction:
The museum extended its hours because it expected more evening visitors.
The best answer depends on the available choices and intended relationship. English is not just a list of grammar rules; some questions ask whether a sentence belongs, where it should be placed, or which wording best supports the author’s purpose.
What the Math section asks you to do
Math covers number and quantity, algebra, functions, geometry, statistics and probability, and modeling. Calculator use follows ACT’s current calculator policy, but many questions still reward efficient reasoning.
Example:
A streaming service charges 8 per month plus 2 per downloaded film. If a customer’s bill is $22, how many films were downloaded?
Model the bill: 8 + 2f = 22. Subtract 8 to get 2f=14, so f=7.
The calculation is simple; the tested skill is translating the context into an equation and answering the requested quantity.
What the Reading section asks you to do
Reading measures key ideas and details, craft and structure, and integration of knowledge and ideas. You may need to locate evidence, infer a supported conclusion, analyze an author’s purpose, or connect information across a passage and graphic.
A strong reading answer is supported by the text—not merely reasonable in real life. If a passage says a pilot program helped three participating schools, an answer claiming the program will help every school is too broad.
Time management matters because Reading includes several passages and a fixed section clock. Our ACT section-timing guide helps students assign checkpoints without forcing identical time on every question.
What the optional Science section measures
ACT Science is primarily a reasoning test built around data and research descriptions. Questions can ask you to read graphs and tables, compare experimental conditions, identify variables, evaluate hypotheses, or analyze conflicting viewpoints. Extensive outside science knowledge is not the main requirement, though some questions can rely on commonly taught foundational concepts.
Example: a graph shows reaction rate rising from 10°C to 30°C and falling at 40°C. A supported conclusion is that the highest measured rate occurred at 30°C. The graph alone does not prove every possible temperature above 30°C produces a lower rate unless those values were tested or the model supports that extrapolation.
For national testing, students decide whether to add Science. For State and District testing, the school or contract determines whether Science is included. Check the expectations of colleges, STEM programs, scholarships, and your school before registering.
What the optional Writing section measures
Writing gives a prompt about a complex issue and three perspectives. Students develop their own position and analyze its relationship to one or more of the provided perspectives. ACT evaluates Ideas and Analysis, Development and Support, Organization, and Language Use and Conventions.
The Writing score does not affect the ACT Composite. Take it only after checking the policies of the programs you care about; requirements are not uniform.
How ACT scoring works
ACT converts raw performance into section scores on the 1–36 scale. The current Composite is based on English, Math, and Reading. Science and Writing have separate reporting, and students who take Science can receive a STEM score based on Math and Science.
ACT superscoring can combine a student’s highest eligible section results across test dates. The current Superscore Composite also uses English, Math, and Reading. Not every college uses superscores, so institutional policy remains important.
Do not interpret a 25 as simply “25 questions right” or a fixed percentage. Use official score reports and current ACT conversion information for the specific practice form.
Online versus paper ACT
Students may encounter paper or online testing, depending on administration and availability. ACT’s national registration page describes paper, online, and bring-your-own-device options at testing sites. Online does not mean at home: secure online testing occurs at an authorized test center or school under supervision.
The content standards are aligned, but the experience differs. Online testers should practice navigation, the secure testing system, and device readiness. Paper testers should rehearse bubbling and page turns. Both need the same underlying English, Math, and Reading skills.
Who takes the ACT?
Many students test in junior or senior year after completing much of their core coursework, but ACT can also be taken earlier or after high school. Some students take it through a state or district school-day program; others register for national testing.
The appropriate date depends on coursework, deadlines, target score, retake time, and other responsibilities. Plan backward from the earliest college or scholarship deadline and allow time for score release.
What colleges do with ACT scores
College testing policies vary. An institution may require scores, be test optional, use scores for placement or scholarships, or apply different rules to certain applicants or programs. “Test optional” for admission does not automatically mean scores are irrelevant to merit aid or placement.
Check the official policy for your entry year. Record whether self-reporting is allowed, whether superscores are accepted, whether Science or Writing matters, and when an official report is due.
ACT versus SAT
Both tests can serve similar college-planning purposes, but their pacing, structure, and question styles differ. The ACT currently has three core sections with optional Science and Writing; the SAT has Reading and Writing plus Math in a multistage adaptive digital format.
Do not choose from reputation alone. Take one current official diagnostic for each under realistic timing, compare score context and experience, and then select the test that offers the clearer improvement path. Our ACT versus SAT guide provides a feature-by-feature comparison.
First steps for a new ACT student
- Open the current ACT section and timing pages.
- Decide whether your administration includes or offers Science and Writing.
- Complete a current official practice set or test.
- Review misses by section, skill, and cause.
- Select two foundational targets for the first week.
- Practice those skills untimed, then in mixed timed sets.
- Retest on fresh questions before taking another full form.
