No college in the United States prefers one test over the other. Both the SAT and ACT are accepted equally at every school that requires standardized testing. So when parents ask which test their child should take, the real answer is: whichever one they score higher on.
What makes that decision difficult is that both tests look similar on the surface but reward different strengths. The SAT and ACT changed significantly in 2024 and 2025 respectively, so the comparison your older friend or sibling made years ago no longer applies.
What Both Tests Look Like Right Now
The SAT went fully digital in March 2024. It runs 2 hours and 14 minutes, covers 98 questions, and scores on a 400 to 1600 scale. Math makes up exactly 50% of the total score. A built-in Desmos graphing calculator is available for all math questions, so students do not need to bring their own. The test is adaptive: how you perform in the first module determines the difficulty level of the second, which means a strong start matters more than it used to.
The ACT launched its Enhanced format in April 2025, with the new version becoming standard for both digital and paper tests in September 2025. The test now runs 2 hours and 5 minutes, covers 171 questions (reduced from the old format's 215), and scores on a 1 to 36 scale. The biggest structural change: the Science section is now optional. Math accounts for only 25% of the composite score. Students can still bring an approved calculator for the math section, but not for science.
The ACT is offered in both paper and digital formats. The digital SAT is taken on the student's own device or a school-issued Chromebook. Students taking the ACT digitally on a weekend are assigned a device they may not be familiar with.
Key Differences Side by Side
Math weight: The SAT puts math at 50% of the total score. If your child is strong in math, the SAT gives that strength room to raise their overall score significantly. On the ACT, math carries less weight, which helps students whose verbal and science skills are stronger.
Time pressure: The SAT gives students more time per question. The ACT moves faster even with the reduced question count. Students who process information quickly and perform well under time pressure tend to do better on the ACT. Students who prefer to think through problems carefully typically favor the SAT.
Science: The SAT does not have a dedicated science section, but it does include data interpretation questions embedded in reading and math. The ACT science section, now optional, tests data analysis and scientific reasoning rather than memorized facts. Students who are strong in analyzing charts, graphs, and experimental results may benefit from sitting the ACT science section, especially if they are applying to STEM-focused programs.
Practice materials: The College Board offers seven free full-length digital SAT practice tests through its Bluebook app, the same platform used on test day. The ACT offers one free downloadable practice test and two web-based practice tests, on platforms different from the actual testing environment.
Does Your Child's College List Matter?
In 2026, over 2,000 four-year institutions maintain test-optional or test-blind policies. However, a number of highly selective schools have reinstated standardized testing requirements. For students applying in fall 2026, Harvard, Yale, MIT, Brown, and Dartmouth all require test scores. Cornell reinstated its requirement for students enrolling in fall 2026.
Even at test-optional schools, submitting a strong score tends to strengthen an application. Research from Ivy League admissions cycles found that most applicants to highly selective schools submitted scores even when they were not required, because scores remain a meaningful signal in a holistic review. If your child's score is at or above the middle 50% range for admitted students at their target schools, submitting it is almost always the right call.
One exception: some states mandate a specific test for high school juniors. Colorado, Illinois, and Michigan require the SAT as part of statewide testing. Alabama, Kentucky, and Tennessee require the ACT. Even so, students in those states can take the other test separately for college admissions purposes.
How to Actually Decide
The single most reliable way to choose is to have your child take a full-length, timed practice test for both. One afternoon on each diagnostic will reveal more about which test fits them than any comparison chart can. Students consistently find that one test feels more natural than the other, even when they cannot initially explain why.
After running the diagnostics, look at where the practice scores land relative to the target schools' middle 50% ranges for each test. If the scores are roughly equivalent, consider which format your child preferred working in. Preparation is easier and more effective when students are not fighting the test format every session.
A few patterns worth knowing: students who struggle with math anxiety often do better on the ACT, where math carries less weight and cannot pull down the total score as severely. Students who are strong readers and thinkers but slower test-takers often score better on the SAT, where the additional time per question removes some of the pressure. Students heading toward science or engineering programs who have strong data analysis skills may want to sit the ACT with the optional science section to show that strength directly.
For a detailed prep plan, once the test is chosen, how to prepare your child for standardized tests covers the full preparation cycle. And if math is the section your child is most anxious about, overcoming math anxiety is worth reading before test prep begins — working on the anxiety itself often improves scores more efficiently than drilling practice problems.
Test Dates in 2025 to 2026
SAT test dates (2025 to 2026 school year): August 23, September 13, October 4, November 8, December 6, March 14, May 2, and June 6.
ACT test dates (2025 to 2026 school year): September 6, October 18, December 13, February 14, April 11, June 13, and July 11.
Students aiming for early decision or early action deadlines should plan to finish testing by October or November at the latest, with an earlier backup attempt in case a retest is needed.
The Bottom Line
Both tests measure the same thing — college readiness — through different lenses. The SAT rewards deliberate, math-heavy thinkers who perform better with slightly more time. The ACT rewards fast processors with balanced subject strengths and an edge in data interpretation.
Take the diagnostic. Check the target schools. Choose the test that plays to your child's strengths. Then prepare with enough time to actually improve, not just familiarize.
