The New ACT Saga Continues: What You Need to Know About the Changes 

News about changes to the ACT exam has been slowly emerging, and much of it feels unclear—or even concerning. This post dives deep into the details, providing a clear explanation of the ACT changes coming in 2025.

For decades, the ACT and SAT have been staples of college admissions, designed to predict students' future academic performance and how they might fare in higher education. These tests are known for their reliability, meaning a student’s results remain consistent regardless of when or where they take the exam.

But now, the ACT is undergoing significant changes, and the implications are causing confusion among educators, parents, and students alike.

Let’s break down what’s happening and how it could impact you or your student’s testing plans. 

Reliability and Myths of Standardized Testing 

First, let’s revisit what makes standardized tests like the ACT valuable in the first place.

• Their reliability ensures that external factors—such as who else is testing on the same day or the location of the testing center—don’t affect results.
• The tests are scaled before administration, ensuring that scores remain fair regardless of the testing date.
• This scaling dispels myths, like the idea that testing on a "popular date" with a large number of seniors will make the test easier due to a curve. That simply isn’t true.

However, while these exams have been reliable, the distinction between a “popular test” and a “good test” remains important.

• A popular test may feel more approachable or “easier,” but that doesn’t necessarily mean it provides the rigor needed to accurately assess a student’s abilities.
• The recent changes to the ACT are raising questions about whether it will remain a “good test” as it attempts to compete with the SAT.

The SAT’s Modernization Push
Over recent years, the SAT has gained ground on the ACT by modernizing its format and making it more appealing to students.

The ACT’s Response
Feeling the pressure to adapt, the ACT is introducing a new version of its exam—shortened and updated in several ways.

What’s Changing?

• Starting in September 2025, the "classic" ACT will be replaced by the "core" ACT.
• While these updates aim to keep the ACT relevant, they have also introduced new challenges and confusion for test-takers and educators.

The Practical Challenges of the New ACT 

One major shift is the move toward a digital format.

• The new ACT Core version is designed to be taken on computers, which raises significant logistical hurdles.
• Schools will need to provide adequate computer labs, manage network requirements, and ensure smooth integration with the ACT’s platform.
• Unfortunately, the ACT’s digital infrastructure doesn’t seem ready for this transition, leaving many schools struggling to accommodate the new format.

Private equity funding behind the ACT hasn’t solved these issues.

• The digital ACT feels like vaporware—announced but not fully functional.
• For students in schools that lack the resources to implement the new format, a paper version will still be available—but only as a backup option.

For now, some schools may still offer the classic ACT for weekday testing through the fall, but this will likely be the last opportunity for students to take the traditional version. 

Should You Stick with the ACT? 

Advice for Current Juniors

• If the ACT aligns with your strengths and you can take the classic version, go for it.
• Diagnostic tests are an excellent tool to determine whether the ACT or SAT is the better fit for you.
• If your diagnostic results show no clear preference, defaulting to the SAT might help you avoid the complications of transitioning to the new ACT format.

When the ACT is the Better Option

• For students who find the ACT better suited to their strengths, it remains a valid choice.
• Even if you need to transition to the core version after July, preparation with the classic format can still provide a strong foundation.
• Plan to take the optional science section of the new ACT—unless you’re certain it won’t be required for your college applications.

What About the Science Section? 

What About the Science Section?

The changes to the ACT include making the science section optional, but this decision introduces even more uncertainty:

• Will colleges still expect students to complete the science section?
• Will it factor into composite scores or super scores across the classic and core versions?

These questions remain unanswered, adding to the complexity of deciding whether to pursue the ACT.

Err on the Side of Caution

• Taking the science section ensures you’re prepared for colleges that might still require it.
• Skipping it could unnecessarily limit your options and close doors to certain schools.

Why the SAT Might Be a Better Choice 

While the ACT grapples with its transition, the SAT has established itself as a stable and modern option. For students who find the SAT format a better fit, it’s an excellent choice. Historically:

• About one-third of students are better suited to the SAT.
• Another third to the ACT.
• The remaining third fall somewhere in the middle.

Having a choice allows students to play to their strengths, which is crucial in maximizing their scores.

Advice for Sophomores

Starting testing too early isn’t advisable. While it may seem proactive, early testing:

• Compresses the preparation timeline.
• Often doesn’t yield the best results.

Waiting until 11th grade provides a developmentally appropriate window for taking these high-stakes exams.

Looking Ahead: Advice for Sophomores and Juniors 

• For the class of 2025, the classic ACT remains a solid option if you can complete testing before the transition to the core version.
• For the class of 2026, however, the testing landscape will likely look very different.

The new ACT will be in full effect, possibly with further adjustments to its format:

• Prep materials for the new version may lag in quality.
• Colleges’ testing policies may still be evolving.

As these changes unfold, staying informed will be critical. Follow updates from testing organizations and colleges to ensure you’re prepared for whatever comes next.

Final Thoughts: ACT Changes Explained 2025

The changes to the ACT bring uncertainty, but with the right preparation and strategy, students can navigate these shifts effectively:

• Diagnostic tests are the first step in identifying which test—ACT or SAT—is the better fit.
• From there, focus on preparing thoroughly for the chosen exam and aim to complete testing within a reasonable timeline.

For students transitioning to the new ACT format, don’t be discouraged:

• While the changes may seem daunting, careful planning and practice can help you adapt.
• For those leaning toward the SAT, rest assured that it remains a stable and reliable choice.

In this evolving landscape, the best approach is to stay informed, flexible, and focused on your long-term academic goals.

Key Takeaways About the New ACT 

• The Classic ACT is Phasing Out: The last chance to take the classic ACT is in July for most students. After that, the new "core" ACT will be the default. 

• Digital Format Challenges: The new ACT core is designed for computers, but many schools lack the infrastructure to administer it seamlessly. A paper version will still be available as a backup. 

• Science Section Changes: The science section is now optional, but students should take it unless certain it won’t be required by their colleges. 

• Reliability Remains Constant: The ACT’s scaling process ensures consistent scoring across testing dates, locations, and formats. 

• Diagnostic Tests Are Essential: Use diagnostics to determine whether the ACT or SAT is a better fit for your strengths and academic goals. 

• Preparation Is Key: Early testing in 9th or 10th grade isn’t necessary; focus on a developmentally appropriate timeline in 11th grade. 

• Consider the SAT: For students who prefer stability, the SAT offers a modern and consistent testing experience and may be the better option during the ACT's transitional period. 

• Stay Informed: College testing policies regarding the new ACT format, optional sections, and super scoring are still evolving. Keep up-to-date with these changes. 

• Plan Ahead: If you’re a junior, aim to finish testing before the transition to the new ACT. For sophomores, prepare for a different testing landscape by the time you’re ready to take these exams. 

• Strategic Flexibility: The best test is the one that aligns with your strengths. Choose wisely and commit to thorough preparation.
