The ACT Core 2026: Should You Take the New Optional Science Section?

For many decades, the ACT (American College Testing) has served as one of the primary college entrance examinations in the U.S. The ACT, which is recognized for assessing what students learn during high school to gauge college preparedness, has traditionally included four main components: English, Math, Reading, and Science. However, with the launch of the ACT Core 2026 and an additional optional science section, candidates are wondering: Is it worth taking? Will it improve my chances of being admitted? Is the extra preparation worth it?

This all-inclusive guide will break down everything essential regarding the new science section: its format, how it varies from the conventional ACT Science Reasoning test, who should consider taking it, and how to prepare strategically if you opt for it.

What Is the ACT Core 2026 and What’s New?

The ACT Core 2026 represents the most recent development of the ACT exam. The traditional ACT included a science reasoning section, but this new optional science section goes further by evaluating not only data interpretation but also deeper scientific thinking and the real-world application of scientific concepts.

The key changes include:

A stronger emphasis on scientific literacy, instead of evaluating disconnected facts
Passage-related queries that mimic actual scientific inquiry
Reasoning that encompasses various fields such as biology, chemistry, physics, and Earth/space sciences
A non-mandatory status, indicating that students have the choice to add it to their test score

This new optional science section provides students with an extra score report that can enhance competitiveness — if used wisely, in contrast to the mandatory sections that nearly all colleges take into account.

The big question is: Should you accept it?

Prior to providing a response, let’s clarify what this section actually involves.

Understanding the New Optional Science Section

To decide whether to take the new science section, you need to know:

1. Section Format and Structure

While the official ACT organization hasn’t released every detail publicly, the new science section is reported to include:

Several science passages with data sets, experiments, graphs, and tables
Questions that test interpretation, evaluation, reasoning, and problem-solving
Integration of concepts across scientific disciplines
A format that encourages scientific literacy, not memorization

This is a departure from the traditional ACT Science Reasoning, which often tested interpretation but included more isolated data sets and straightforward scientific reasoning.

2. Time and Pacing

Like other sections of the ACT, pacing remains crucial. You will face numerous questions under timed conditions, and since science tends to involve reading complex graphs and setups, effective time management is key.

3. Scoring

Your results on this non-mandatory science part will produce an independent score, akin to the subject-level scores provided by the SAT. As a result, colleges will have access to both your composite ACT score and your science section score.

Your application can be bolstered by this dual reporting, but only if your performance is robust.

Why This Matters: The College Admissions Angle

As more universities adopt test-optional or test-flexible policies, standardized tests are no longer the only determining factor, but they can still affect admissions decisions, particularly for competitive programs.

Here’s why the new science section can matter:

1. It Shows Depth in Scientific Thinking

For STEM aspirants — especially those applying to programs like biology, chemistry, engineering, or environmental science — a strong science score demonstrates:

Ability to analyze scientific data
Interpretation of complex information
Critical thinking skills relevant to real-world science

This can be a differentiator when your overall ACT score is similar to another candidate’s.

2. It Can Bolster Your Application Even Outside STEM

Some colleges may view a strong science score as evidence of academic rigor and analytical ability, traits that matter across disciplines.

3. It Offers More Score Reporting Options

If you’re testing multiple times, or aiming to maximize your score mix, the optional science score provides another metric to showcase your strengths — especially if you excel in science.

Should You Take the Optional Science Section?

The answer isn’t the same for every student. But here’s how you can decide based on your goals:

If You’re a STEM-Focused Applicant

YES, strongly consider it.

If you’re planning to pursue:

Biology
Chemistry
Physics
Engineering
Medicine
Computer science
Environmental science

then a strong optional science score can give you an edge — particularly at competitive schools where small score differences can affect admissions decisions.

STEM programs want students who think scientifically and reason with data. This optional section is designed to measure those very skills.

If You Excel in Science

Even if you’re not applying to STEM majors, but you perform well in science, taking this section could be advantageous.

Why?

It allows you to highlight a strength
It adds depth to your academic profile
You can outshine other applicants with similar general ACT scores

Bottom line: A strong optional science score strengthens your candidacy.

If You Struggle With Science or Don’t Enjoy It

Then the answer may be NO — unless you improve your science skills first.

If science is your weakest area — and boosting this score could hurt your overall confidence or performance — then skip it.

However, if you have time to prepare effectively, you may decide that improving scientifically is worthwhile.

If Your Target Colleges Don’t Emphasize Test Scores

Some colleges are test-optional or even test-blind, meaning standardized tests play a lesser role or aren’t considered at all.

Before you decide to take the optional science section, research the admissions policies of your target schools.

If the schools don’t consider the ACT score seriously, or place minimal weight on test scores, then:

The science section may not benefit you

But it won’t harm your score either (as long as you do reasonably well)

If You’re Applying to Competitive Programs

In highly competitive programs, even non-STEM majors can benefit from metrics like science reasoning to add depth to their application.

In these situations, taking the science section (and doing well) can be beneficial, even though it’s not required.

How to Prepare for the Optional Science Section

If you decide to take it, preparation is key.

Here’s a practical, realistic strategy:

1. Build a Strong Foundation in Science Fundamentals

You don’t need to memorize loads of facts — focus on:

Scientific reasoning
Interpreting graphs and data
Understanding experimental designs
Making logical inferences

Books like AP Science review guides, SAT/ACT Science prep materials, and science textbooks can help.

2. Practice With Realistic Passage-Based Questions

Since the new section emphasizes reading and reasoning:

Solve passages with graphs
Interpret results and hypotheses
Draw conclusions based on data

Look for sample tests, science reasoning practice books, and online resources that simulate ACT Core question styles.

3. Hone Your Data Interpretation Skills

A huge part of this section is being able to:

Analyze trends
Compare data sets
Interpret charts and tables
Evaluate experimental outcomes

The more you practice with real data, the faster and more confident you’ll become.

4. Time Yourself

Because timing is limited, practice under timed conditions to simulate real test day pressure.

This improves:

Speed
Decision-making
Confidence

5. Identify Your Weaknesses Early

As you practice:

Track wrong answers
Understand why you got them wrong
Revisit the concepts

This targeted review is far more effective than blind study.

6. Join Science-Focused Prep Programs if Necessary

If science really isn’t your strength, consider:

ACT coaching
Online science reasoning courses
Tutoring focused on data analysis

The goal isn’t memorizing science facts — it’s mastering the thinking behind science.
