Quick Reference

The ACT at a Glance

The ACT is a college admissions test that measures academic readiness in English, Math, and Reading, with optional Science and Writing sections. Here is the quick version.


Scoring:

Each section is scored 1 to 36. The Composite is the average of English, Math, and Reading, rounded to the nearest whole number.

Length:

Approximately 2 hours and 5 minutes of testing time for English, Math, and Reading. Optional Science and Writing each add 40 minutes.

Format:

Offered on paper and online for U.S. national testing, although availability varies by testing location and administration. Unlike the digital SAT, the ACT is linear rather than adaptive, so the test does not change based on a student’s performance.

Guessing:

There is no penalty for a wrong answer, so it is always worth answering every question.

When:

offered several times a year, typically September, October, December, February, April, June, and July. Most students test in junior or senior year.


What Changed with the Enhanced ACT

The ACT has changed. Here is what students need to know.

The enhanced ACT began rolling out in 2025 and is now used for national testing and state- and district-administered testing. The updated exam is shorter, allows more time per question, and gives students greater flexibility around its optional sections.

  • The required test consists of English, Math, and Reading, and the Composite score is calculated from those three sections. Students who take Science receive separate Science and STEM scores, but Science does not affect the Composite. For national testing, students choose whether to add Science; in school-day testing, that decision may be made by the state, district, or school.
  • The core exam now takes approximately 2 hours and 5 minutes. Math questions have four answer choices rather than five, the English section includes shorter passages, and Reading includes fewer questions and passages with more time per question.
  • For U.S. national testing, paper and online formats are available where offered. The ACT remains linear rather than adaptive, meaning the test does not adjust based on a student’s performance.
  • One of the most important planning questions is whether to take the optional Science section. That decision should reflect the student’s strengths, academic interests, testing context, and the current policies of the colleges they are considering.

Your ACT questions, answered.

What is the ACT?

The ACT is a standardized college admissions test that measures academic readiness for college. Its core sections are English, Math, and Reading, with an optional Science section and an optional Writing section.

What sections are on the ACT?

Three core sections: English, Math, and Reading. There is also an optional Science section and an optional Writing section.

How is the ACT scored?

Each section is scored on a scale of 1 to 36. Your Composite score is the average of English, Math, and Reading, rounded to the nearest whole number. Science is no longer part of the Composite. Students who take it receive a separate Science score and a STEM score that averages Math and Science.

What is the enhanced ACT, and what changed?

In 2025 the ACT was redesigned. The Science section became optional, the Composite is now based on English, Math, and Reading, the test is shorter with more time per question, Math questions have four answer choices instead of five, and passages are shorter. As of 2026 this format applies to all national and school-day testing.

Is the Science section required?

For national ACT testing, students can choose whether to add the Science section. In state- and district-administered testing, the school or testing program determines whether Science is included. Science does not factor into the current Composite score, but students who take it receive separate Science and STEM scores. Students should also review the current policies of the colleges they are considering.

How long is the ACT?

The core sections, English, Math, and Reading, take about two hours. The optional Science and Writing sections add roughly 40 minutes each.

What is the difference between the ACT and the SAT?

Both are widely accepted college-admissions tests, but their structures differ. The SAT is fully digital and adapts between modules based on a student’s performance. The ACT is linear, may be offered on paper or online depending on the administration, and includes optional Science and Writing sections. Many students complete a practice version of each before deciding where to focus.

When can my student take the ACT, and when should they?

The U.S. national ACT is generally offered seven times each year, typically in September, October, December, February, April, June, and July. Many students first test during junior year, leaving time for another sitting if appropriate. Always consult ACT’s current calendar when planning.

How do I register?

Register online through the official ACT website. Create an account, choose a test date and location, select whether to add the optional Science and Writing sections, and pay the fee.

Can my student retake the ACT?

Yes. There is no overall limit on how many times a student may take the ACT, although retesting should be purposeful. Another sitting is most valuable when there is time for targeted preparation and a reasonable opportunity for improvement.

Do colleges see all of my ACT scores?

It depends on the college. Many superscore the ACT, taking your best section scores across test dates. Others ask you to send all your scores. Policies vary, so confirm for each school on your list.

Is the ACT required for admissions?

Testing policies vary by college and can change from one admissions cycle to the next. Some institutions require test scores, others are test-optional, and some do not consider them. Always confirm the current policy directly with every college on your list.

Can my student use a calculator?

Yes on the Math section, using a calculator from the ACT’s approved list. Calculators are not permitted on the Science section.

What is the Writing (essay) section?

The optional Writing section is a 40-minute essay in which students develop a position on a complex issue and respond to multiple perspectives. It does not affect the Composite score. Requirements vary, so students should check the policies of their schools and testing programs before registering.

How do I send scores to colleges?

You can send scores to up to four colleges for free when you register. Additional score reports can be sent later for a fee.

How can my student improve their ACT score?

Meaningful improvement begins with understanding the current format, practicing under realistic timing, and focusing on the skills and question types that need the most attention. One-on-one tutoring can provide individualized feedback, structure, and accountability. Our tutors build each preparation plan around the student’s existing scores, practice work, goals, and areas for growth.
