Learn about the major changes coming to the ACT in 2025, including a shorter test time, optional science section, and other key updates to help you succeed.
The ACT is undergoing its biggest transformation in decades. Starting in 2025, students will experience a shorter, more flexible exam that aims to reduce test anxiety while maintaining its value for college admissions. These changes reflect both evolving educational needs and technological advances in testing.
Why the ACT Is Evolving
The ACT's mission has always been to help students succeed in their journey to higher education. These upcoming updates reflect that mission through:
Student-Centered Approach: By offering a shorter test, fewer total questions, and the option to skip the science section, test takers can tailor the exam to their own strengths and college goals.
Better Access: Online testing will adopt these changes first, making it easier for students to schedule and take the exam in a way that suits them.
Meaningful Scores: Colleges continue to rely on the ACT as a reliable assessment, and now there will be an even sharper focus on the key academic areas of English, math, and reading.
Key Updates Coming to the ACT
1. Shorter Exam, Fewer Questions
The revised format removes a total of 44 questions, offering a more streamlined experience:

2. Flexible Science Section
One of the biggest changes is that the science section will now be optional for most testers. If you are aiming for a STEM degree, you will want to consider including science for a more robust score profile. Students who skip it will still get a composite score based on English, math, and reading.
3. Revised Composite Score
Beginning in April 2025 for online tests and September 2025 for paper tests, the Composite score will only factor in English, math, and reading. Science results (when taken) will still appear separately and will continue to be valuable for college admissions and scholarships, especially in STEM fields.
4. More Time per Question
With the total number of questions reduced, you will have slightly more time to think through each one. This can lower stress levels and help you focus on providing the best possible answer for every prompt.
5. Four Answer Choices in Math
The mathematics section now has four answer choices instead of five. This update can help you work through problems more efficiently and potentially improve your chances of identifying the correct response.
6. No Fifth Test (Field Test Section)
Starting April 2025 for online testers, you will not see the additional "Test 5" section that was used for field-testing questions. This means less overall time spent testing.
What Remains the Same
Despite these adjustments, the ACT is holding on to many of its foundational elements:
1-36 Scale: The ACT scoring scale is not changing, so scores remain familiar and comparable.
College Predictive Power: The ACT will continue to provide a trustworthy measure of your ability to succeed in first-year college courses.
Writing Option: The optional Writing test still exists.
Score Reporting: Past ACT scores remain valid and unchanged, and superscoring will continue.
When Do These Changes Happen?
Date
Change
April 2025
Online-only ACT test-takers in the U.S. experience the updated format
September 2025
Paper-based ACT tests in the U.S. and the international ACT test adopt the new structure
Spring 2026
Schools and districts that administer the ACT on statewide/district test dates roll out enhancements
How to Prepare
Tip: Current study tools are still helpful because the skills tested in English, math, reading, and science remain the same. Focus on building strong foundational knowledge.
Stay Informed: Keep tabs on official ACT announcements. Practice tests and updated prep materials are available.
Use Existing Resources: Current study tools remain helpful because the skills tested remain the same.
Pick Your Sections Wisely: If you are set on a STEM path, consider taking the optional science portion.
Plan Your Testing Timeline: With shorter sessions, you can schedule your test around other commitments more efficiently.
The ACT's commitment to supporting students has driven these important updates. By 2025, you will have a chance to sit for a more flexible, shorter test while still showcasing your academic abilities in all the areas colleges care about.
Online ACT tests in the U.S. adopt the new format in April 2025. Paper-based and international tests follow in September 2025. Schools and districts using statewide ACT testing will roll out changes in Spring 2026.
The new ACT has 131 core questions: 50 English (35 min), 45 Math (50 min), and 36 Reading (40 min). The optional Science section adds 40 questions in 40 minutes.
No. Starting in 2025, the Science section is optional. Your composite score is calculated from English, Math, and Reading only. Science scores are reported separately if you take that section.
No. The 1-36 scoring scale remains the same. The composite is now the average of three sections instead of four. Superscoring across test dates also continues.
