SAT vs ACT: Which Test Should My Child Take?
Here is the most important thing to know upfront: virtually all colleges and universities in the United States accept both the SAT and ACT equally. No school prefers one over the other. Admissions officers have confirmed this repeatedly. So the question is not which test colleges want - it is which test plays to your child's strengths.

The Science Section Question
The ACT's science section scares a lot of families, but here is what it actually tests: data interpretation and scientific reasoning, not science knowledge. Your child does not need to memorize the periodic table or know biology facts. The section presents graphs, charts, experiment descriptions, and conflicting viewpoints, then asks students to analyze them.
Students who are good at reading charts and making logical inferences tend to do well on ACT Science - even if they do not consider themselves "science people." Students who struggle with data interpretation or get overwhelmed by unfamiliar graphs may find this section challenging.
The Pacing Difference
This is often the deciding factor. The ACT gives you less time per question across every section. Students who work quickly and trust their first instinct tend to prefer the ACT. Students who like to think carefully, re-read passages, and double-check work tend to prefer the SAT, which allows more time per question.
A simple test: have your child take a timed practice section of each test. If they run out of time on the ACT but finish the SAT comfortably, the SAT is likely a better fit. If they breeze through both, the ACT may yield a higher score since speed is rewarded.
Which Student Profile Fits Which Test?
Your child may score higher on the SAT if they:
- Are strong in algebra and data analysis but weaker in geometry
- Prefer working at a measured pace with time to think
- Excel at evidence-based reasoning ("which line in the passage supports your answer?")
- Are comfortable with digital, adaptive test formats
- Do not want a science section
Your child may score higher on the ACT if they:
- Work quickly and accurately under time pressure
- Are strong across all math topics including geometry and trigonometry
- Are good at reading graphs and interpreting data
- Prefer straightforward questions over tricky wording
- Have strong science grades (even though the section tests reasoning, not knowledge)
The Best Way to Decide
Take a full-length, timed practice test of each. This is the single most reliable way to determine which test suits your child better. Both the College Board (SAT) and ACT offer free official practice tests.
Compare the scores using a concordance table (available on both organizations' websites) to see which test yielded a stronger result. Many students score comparably on both - in that case, go with whichever felt more comfortable.
The ideal timeline:
- Fall of sophomore year or spring of junior year: Take diagnostic practice tests of both
- Choose your test based on results and comfort
- Prep for 8-12 weeks before your target test date
- Take the test in spring of junior year, with a retake option in fall of senior year if needed
Prep Costs
Test prep ranges from free to very expensive:
- Free: Khan Academy (official SAT prep partner), ACT Academy, free practice tests from both organizations
- Self-study books: $20-$40 (Princeton Review, Barron's, official guides)
- Online courses: $100-$500 (Magoosh, PrepScholar, Kaplan online)
- Group prep classes: $500-$1,500 for 6-10 week programs
- Private tutoring: $75-$200 per hour, with most students needing 10-20 hours
Research consistently shows that consistent practice matters more than expensive prep. A student who works through free Khan Academy materials for 20 hours will likely improve more than one who attends a few expensive tutoring sessions without practicing between them.
Test-Optional Schools - Does It Even Matter?
Many colleges went test-optional during the pandemic, and some have stayed that way. However, the trend is shifting back toward requiring scores - several elite universities have reinstated test requirements. Even at test-optional schools, submitting a strong score can help your application.
The practical advice: prepare for and take one of the tests. If the score is strong, submit it. If it is not, apply test-optional where you can. Having the option is better than not.
The Verdict
There is no universally "better" test. Colleges accept both equally. The right test is whichever one your child scores higher on and feels more comfortable taking.
Take a practice test of each. Compare scores. Choose the one that plays to your child's strengths. Then invest prep time into that single test rather than splitting focus between both.
If scores are similar on both, lean toward the SAT for students who like to work carefully, and the ACT for students who work quickly and are comfortable with the science section.
Frequently Asked Questions
Do colleges prefer the SAT or ACT?
No. Virtually all U.S. colleges and universities accept both tests equally and have no preference. This includes Ivy League schools, state universities, and everything in between. Admissions officers evaluate SAT and ACT scores using concordance tables that make them directly comparable. Submit whichever score is stronger.
When should my child start preparing?
Most students benefit from taking a diagnostic practice test in fall of sophomore year or early junior year to choose between the SAT and ACT. Focused prep should begin 8 to 12 weeks before the target test date, with the first official attempt in spring of junior year. This leaves time for a retake in fall of senior year if needed.
Can my child take both the SAT and ACT?
Yes, and some students do. However, most test prep experts recommend focusing on one test and preparing thoroughly rather than splitting time between both. Take a practice test of each to identify the stronger option, then dedicate all your prep time to that one test. Preparing for both simultaneously dilutes effort and rarely produces better results.
