One of the most common questions families face in high school is whether to take the SAT, the ACT, or both. The good news: every accredited college and university in the United States accepts both tests equally. There's no admissions advantage to one over the other.
The question isn't which test colleges prefer. The question is which test your student is more likely to score higher on — and the answer is different for every student.
Here's how to figure it out.
The Core Differences Between the SAT and ACT
Before choosing, it helps to understand what makes the two tests structurally different.
Format and Timing
The SAT has two sections — Math and Reading & Writing — plus an optional essay (which most colleges no longer require). Students have more time per question on the SAT than on the ACT, which matters for students who read carefully but work at a deliberate pace.
The ACT has four sections: English, Math, Reading, and Science, plus an optional Writing section. The ACT is notably faster-paced. There are more questions in less time, and the Science section — which doesn't appear on the SAT at all — adds a category that surprises many first-time test-takers.
Math Content
SAT Math puts heavy emphasis on Algebra and Advanced Math (quadratics, functions, exponential equations). About 35% of SAT Math questions fall into each of those two areas.
ACT Math covers a broader range, including trigonometry and some topics that students typically encounter in pre-calculus. It also permits a calculator on all math questions, whereas the SAT has a no-calculator module.
Students who are strong in Algebra and functions tend to do relatively well on SAT Math. Students who have covered more advanced math through pre-calc or beyond may find the ACT Math section more comfortable.
Reading Style
Both tests require reading comprehension, but they approach it differently.
SAT Reading & Writing questions are shorter and more focused — each question is tied to a shorter passage or paired passages, and the test asks very specific questions about evidence, word choice, and structure. The questions are precise.
ACT Reading presents four longer passages and asks broader comprehension questions. Students have about 52 seconds per question on the ACT Reading section, which rewards fast readers who can absorb a passage quickly.
The ACT Science Section
This is the biggest structural difference. The ACT Science section isn't really a science test — it's a data interpretation test. It presents graphs, tables, and experimental results and asks students to read and interpret them. Students with strong analytical reading skills often do well here regardless of their science background.
That said, students who don't expect this section can be caught off guard. If your student hasn't taken a practice ACT, the Science section is worth previewing before test day.
Which Students Tend to Prefer the SAT
The SAT tends to be a better fit for students who:
- Are strong in Algebra but haven't covered much pre-calculus or trigonometry yet
- Prefer working more carefully and methodically rather than quickly
- Are better at close reading of shorter, more specific passages than speed-reading longer ones
- Are in 10th or early 11th grade and haven't finished their full math sequence yet
The Digital SAT, which College Board rolled out in 2024, is also adaptive — the second module of each section adjusts in difficulty based on your first-module performance. Strong test-takers get harder questions in the second module, which allows them to demonstrate higher ability and earn higher scores. Students who test well under standard conditions often find this format rewards them.
Which Students Tend to Prefer the ACT
The ACT tends to be a better fit for students who:
- Are fast readers who can move through a 700-word passage in under two minutes
- Have completed or are taking pre-calculus or trigonometry
- Are comfortable interpreting graphs and experimental data quickly
- Find the SAT's very precise, evidence-based reading questions frustrating
Some students also simply find the ACT's structure more intuitive — four clearly labeled subject sections feel more familiar to students accustomed to taking subject-specific exams in school.
The Best Way to Decide: Take a Practice Test for Both
The most reliable way to determine which test is a better fit is to take one official practice test for each and compare the results — not the raw scores, but the score percentiles. A 1200 on the SAT and a 26 on the ACT are roughly equivalent (both around the 74th percentile), so comparing percentiles tells you which test your student is performing better on relative to other test-takers.
Free official practice tests are available from both College Board (for the SAT) and ACT.org. Schedule both on separate weekends, score them, and compare percentile rankings. Let the data make the decision for you.
If the percentiles are nearly identical, it doesn't matter much which test you choose. If one is clearly higher, that's your answer.
What About Taking Both?
Some students take both tests and submit whichever score is stronger to colleges. This strategy works, but it comes with a cost: preparing for two different tests splits your study time and can prevent you from reaching your full potential on either one.
A better approach for most students: take a diagnostic practice test for both, identify which test you're likely to score higher on, and then invest all of your prep time in that one test. A focused student who prepares seriously for one test will almost always outperform a student who prepares lightly for two.
If after your diagnostics the scores are genuinely tied, pick the SAT — not because it's better, but because your student's school likely offers the SAT as the state-required exam, making it easier to access official test dates and prep resources.
A Note on the PSAT
If your student is in 9th, 10th, or 11th grade and hasn't taken either test yet, the PSAT is a valuable first data point. The PSAT is structured like a shorter SAT and gives students their first look at their performance across the SAT's skill areas. It's also the qualifying test for the National Merit Scholarship Program for 11th graders. See our full PSAT vs SAT comparison for a detailed breakdown of how the two tests differ and what the PSAT can do for your student's college prep.
Students who take the PSAT in October of 11th grade and score in the top tier for their state become National Merit Semifinalists — a recognition that carries real weight in college applications and scholarship consideration.
The Bottom Line
There is no universally "easier" test. The right test is the one that plays to your student's specific strengths. A fast reader with strong science reasoning may score better on the ACT; a student who excels at algebra and careful reading may do better on the SAT.
Take the diagnostics, compare the percentiles, and let the data guide the decision. Then focus all prep time on one test and go after the best score possible.
