If you are preparing for the ACT in 2026, you have a decision that previous test-takers did not have: ACT Science is optional. Since the enhanced ACT, the Science section no longer contributes to the Composite score, which is now calculated using English, Math, and Reading.
But that does not automatically mean you should skip it. The answer depends on your college list, intended major, academic strengths, and testing strategy. This guide explains whether ACT Science is optional, who should take ACT Science, whether colleges require it, and when taking the extra section can still make sense.
Is ACT Science Optional in 2026?
Yes. ACT Science is optional on the enhanced ACT. Students can take the ACT with English, Math, and Reading only, or add the Science section.
The change began with enhanced ACT administrations in 2025 and has since become part of the standard ACT structure. The current ACT lists Science as an optional add-on consisting of 40 questions in 40 minutes.
The biggest change is scoring. Your ACT Composite is now based only on:
|
Required ACT section |
Time |
Questions |
|
English |
35 minutes |
50 |
|
Math |
50 minutes |
45 |
|
Reading |
40 minutes |
36 |
|
Science, optional |
40 minutes |
40 |
Science receives its own 1 to 36 score if you take it, but it is not included in the enhanced ACT Composite. That distinction is important. The question is no longer, "Can I handle ACT Science?" It is, "Does taking ACT Science add value to my application?"
What Does the ACT Science Section Actually Test?
One common misconception is that you need to be an exceptional biology, chemistry, or physics student to do well on the ACT Science test.
That is not quite how the section works. ACT describes Science as a test of interpretation, analysis, reasoning, evaluation, and problem-solving using scientific information. The section includes data interpretation, scientific investigations, and evaluation of scientific arguments and models. In practice, you may encounter:
- Graphs and tables
- Experimental results
- Research summaries
- Scientific models
- Relationships between variables
- Conflicting scientific viewpoints
So, the science portion of the ACT is optional, but the skills it measures can still be useful evidence of your ability to work with quantitative and scientific information. In fact, ACT's current Science College Readiness Benchmark is 23, representing its readiness benchmark for introductory biology coursework.
Do Colleges Require ACT Science?
Not necessarily. Colleges and universities set their own testing policies, and ACT specifically advises students to check each institution's requirements.
ACT Science being optional also doesn't mean every college will treat the section the same way. ACT has stated that colleges can continue to use ACT superscore data for admission, scholarships, and course placement after the testing changes. It also notes that some colleges or programs may require Science.
Therefore, before deciding not to take ACT Science, check the admissions pages for every college on your list.
A simple way to approach your college list:
|
Your Situation |
What to Consider |
|
Your colleges do not require or recommend Science |
You may choose to skip it |
|
A college or program requires Science |
Take it |
|
You plan to study STEM |
Taking Science may provide useful additional evidence |
|
You are undecided about your major |
Taking Science can keep more options open |
|
Science is one of your strongest subjects |
Consider taking it to showcase that strength |
|
You perform significantly better without Science |
Compare the value of the section against the additional testing time |
The important point is that there is no universal "always take it" or "always skip it" rule.
Who Should Take ACT Science?
Since ACT Science is optional, the answer varies by student.
1. Students Applying to STEM-Related Programs
If you are considering biology, engineering, chemistry, environmental Science, or another science-heavy field, taking ACT Science can give colleges an additional data point about your scientific reasoning.
ACT itself recommends considering the Science section for students interested in STEM. However, do not confuse "useful" with "universally required." A student's actual college list should determine whether the section is necessary.
2. Students Who Are Strong at Data Interpretation
You might not love your science classes and still do well on ACT Science. Why? Because ACT Science rewards skills such as reading graphs, identifying trends, comparing data, and understanding experimental setups.
If you naturally look at a chart and immediately ask, "What changed, and why?" the section may suit you.
3. Students With Strong Science Grades
A strong ACT Science score can provide another way to demonstrate scientific ability.
ACT specifically notes that a strong Science score can make an application more competitive and may be particularly useful when a student's science coursework does not fully reflect their abilities.
That does not mean ACT Science can replace strong grades, rigorous coursework, or other parts of an application. It is simply another piece of information.
4. Students Who Want to Keep Options Open
If you are a sophomore or junior who has not settled on a major, ACT Science may be worth taking.
Skipping the section saves time, but taking it gives you a reportable Science score that you can submit if it becomes useful later. ACT confirms that it reports Science scores separately for students who take the section.
Who Might Skip ACT Science?
Because ACT Science is optional, students can be strategic.
If none of your target colleges or programs requires or recommends Science, and your diagnostic testing shows that the section adds little value to your application, skipping it can be reasonable.
There is also a practical consideration: Science adds 40 minutes and 40 questions.
For a student who performs strongly on English, Math, and Reading but finds Science consistently draining, those additional 40 minutes may not be the best use of testing time.
Can ACT Science Still Help Your College Application?
Yes, potentially. ACT states that Science scores remain available to colleges and can be used for admission, scholarships, and course placement. This means students should think of Science as an additional credential, rather than a component of their primary Composite score.
For example, imagine two students with identical Composite scores:
- Student A has a strong Science score, indicating an interest in STEM.
- Student B chooses not to take Science.
Neither approach is automatically better. The relevance depends on the student's college list and overall academic profile.
Conclusion
ACT Science is optional, but that does not mean it has no value. Your decision should depend on your target colleges, intended major, academic strengths, and practice performance. Check each college's current testing policy before registering, especially if you are considering a STEM program.
If Science can strengthen your application, taking it may be worthwhile. If not, you can focus your preparation on the required ACT sections.

Frequently Asked Questions
Is ACT Science optional for all students?
Yes. On the enhanced ACT, students can choose whether to take the Science section. However, individual colleges or programs may have their own testing requirements, so always verify your target schools' policies.
Does ACT Science affect my ACT Superscore?
Science is reported separately under the enhanced ACT, and ACT's superscoring policies depend on how an institution uses ACT scores. Students should check both ACT's current policy and their target colleges' requirements.
Can ACT Science improve my college application?
It can give colleges an additional measure of scientific reasoning, especially for students interested in STEM. Whether it strengthens your application depends on the college, program, and the rest of your academic profile.
Is ACT Science harder than the other ACT sections?
Difficulty is subjective, and the section tests a different skill set. ACT Science can feel challenging because students must interpret unfamiliar experiments, graphs, and data quickly rather than recall information from a science textbook.
