SAT or ACT? The Choice is Clear
February 17, 2026

For years, high school juniors have had to decide on which standardized college admissions test to take. For some, the choice is made by their states. More than 25 states require either the SAT or ACT as a part of their state-wide testing requirements or as a requirement for graduation. For others, it’s a question of access; one test may be administered by their district while the other is not. Many students have the option of taking either exam, and may take practice exams for both tests to see on which one they get the higher score.
The two tests have always been a little different. The SAT reading sections feature short paragraph readings while the ACT reading sections feature longer passages with more questions. The math sections differ as well. The SAT math section focuses more heavily on algebra, while the ACT exam features more geometry and trigonometry. The SAT requires students to work at a faster pace to complete all of the math questions than the ACT does.
In 2024, the College Board changed the structure of the SAT. The test is now digital and adaptive. Students complete a set of basic questions for each of the three core tests and then, depending on how they do, are shifted to one of two advanced sections. Students that scored higher on the basic questions get the harder advanced section and can achieve higher SAT scores. According to the College Board, this allows students to take a much shorter exam with equal predictive ability.
In 2025, ACT began to unroll their new, Enhanced ACT digital platform. This version features three core tests – English, Math and Reading, with two optional tests - Science and Writing.
But while the digital SAT is empirically equivalent to the old SAT, the Enhanced ACT is fundamentally different from the legacy ACT exam.
First, there are less questions (175 core questions vs 108 on the Enhanced ACT), but unlike the SAT where there is a predictive component, all students answer the same questions. The enhanced ACT test is longer than 108 questions, it’s actually 134 questions long. This is because each section has embedded field-test questions (FTs). These experimental questions do not count in the final scoring, instead they are being tested for future ACT exams.
There are two very important implications because of the FT questions. The first is a matter of numbers. There are so few questions for the core sections that there is no margin of error. Miss a question, you drop by at least one point on the section score. In fact, there aren’t enough questions to allow certain scores at all. If you miss two questions on the English section of the Enhanced ACT, you score a 35 for the section. Miss one more question, and your score drops to a 33. It’s simply not possible to get a 34. Or a 30. In the Reading section, you can’t score a 33, a 27 or a 19 and in the optional Science section, you can’t get a 13. Because there is such a premium on correctly answering each question, Compass Education recommends the following strategy for taking the ACT exam:
The takeaway for students opting for the ACT is clear: make sure that they are going into official exams with an airtight command of strategies and timing to avoid careless mistakes and excessive amounts of guessing. And plan on a retest or two as a safeguard against unlucky guessing.
The second problem occurs when students guess, especially if they don’t have enough time to complete all of the questions on the exam. There are four passages in the Reading section, each with 9 questions. One of those passages is an FT and won’t count. If a student runs out of time and chooses to guess at one of the passage questions, and it’s the FT passage, they get a really good score for the section. If it’s one of the other passages and they spent their time on the FT passage, they get a much lower score. Hint for students taking the ACT – the FT passages in English, Reading or Science is never the first or last; the FT questions in the Math sections are never at the beginning or the end of the test.
While both the SAT and ACT offer an optional Writing section, very few schools will look at it and only two schools require it. Most students elect not to take the section. The Science section, however, is unique to the ACT. Here’s were it gets confusing. A few schools (Boston University, Pomona and Georgetown) require it. A few other schools (Duke, Michigan State and the Rochester Institute of Technology) recommend students take it. And some schools (like Penn State or BYU) won’t even look at it if it’s included on the application. Just to complicate it further, some schools average Science into their ACT composite score and some do not. Some schools (like Swarthmore) insist that students who take the Science section include it on their applications, while other schools (like Kansas State) will look at the score only if it helps the students. Hint: Before taking the ACT Science section, go to each school’s website on your college list and see how they will use Science in your ACT score.
As you can see, I’ve spent a lot of time talking about the ACT exam, and just mentioned the SAT in passing. That’s not a slight to the College Board! But before students invest time studying for the ACT and taking hours of test prep, it’s important they know the dark side of the test. The ACT test has so many problems with variability, interpretation and scoring it’s hard to recommend it. I suggest to my students they take the SAT unless they feel much more comfortable with the ACT long-passage format and it translates to a noticeably better score on a practice test or two. I don’t recommend they take the Science test unless they have an overriding reason for doing so.
SAT or ACT? The answer is clear. Take the SAT unless you have a strong rationale for taking the ACT instead.
