Choosing between the SAT and ACT is one of the first major decisions in the college admissions process. Both tests are widely accepted by U.S. colleges, but they have different formats, pacing, and content emphasis. Here's how to determine which test is the best fit for your child.
Key Differences Between SAT and ACT
| Feature | SAT | ACT |
|---|---|---|
| Total Time | 3 hours (without essay) | 2 hours 55 minutes (without essay) |
| Sections | Reading, Writing & Language, Math (2 parts) | English, Math, Reading, Science |
| Score Range | 400-1600 | 1-36 |
| Math Content | Algebra, geometry, trigonometry, data analysis | Same, plus more trigonometry |
| Science Section | No dedicated section | Yes (35 minutes) |
| Calculator Use | Allowed on one math section only | Allowed on entire math section |
| Pacing | More time per question | Faster pacing required |
Who Should Take the SAT?
The SAT may be a better fit if your child:
- Prefers more time per question: The SAT allows slightly more time to think through problems
- Excels at vocabulary and reading comprehension: The SAT emphasizes evidence-based reading
- Is strong in algebra and data analysis: Math focuses heavily on these areas
- Prefers working without a calculator: One math section prohibits calculator use
- Likes analyzing passages and finding evidence: Reading questions often ask for textual support
Who Should Take the ACT?
The ACT may be a better fit if your child:
- Works well under time pressure: The ACT requires faster pacing throughout
- Is comfortable with science reasoning: The science section tests data interpretation and analysis
- Prefers straightforward questions: ACT questions tend to be more direct
- Is strong in trigonometry: The ACT includes more advanced math topics
- Likes having a calculator available: Calculators are allowed for all math questions
Important Note: The ACT Science section doesn't require extensive science knowledge—it tests the ability to read charts, graphs, and experimental data. Students strong in data analysis often do well.
How to Decide: Take Practice Tests
The best way to determine which test suits your child is to take full-length practice tests for both:
- Take official practice tests: Use College Board's SAT practice and ACT's official tests
- Simulate real testing conditions: Timed, quiet environment, no breaks beyond what's allowed
- Compare scores using concordance tables: Convert scores to see which test yields better results
- Consider comfort level: Which test felt more natural? Which sections were less stressful?
Can Students Take Both Tests?
Yes, and many students do. However, it's generally more effective to:
- Take diagnostic tests for both early (sophomore or early junior year)
- Choose one test to focus on based on results and comfort
- Dedicate prep time to mastering that test
- Consider taking the other test only if the first doesn't go as planned
Splitting prep time between both tests can dilute focus and reduce score improvement. Most students benefit from concentrating on one test.
Do Colleges Prefer One Test Over the Other?
No. All U.S. colleges and universities accept both the SAT and ACT equally. Admissions officers use concordance tables to compare scores, so there's no advantage to taking one test over the other from an admissions perspective.
Choose the test where your child can achieve their highest score—that's what matters most.
When Should Students Start Preparing?
- Sophomore year: Take diagnostic tests to identify strengths and weaknesses
- Junior year (fall): Begin focused test prep (3-6 months before first official test)
- Junior year (spring): Take the official test for the first time
- Summer before senior year: Retake if needed to improve scores
Tip: Most students improve their scores on a second attempt, especially with targeted preparation between tests.
Test-Optional Policies: Should Students Still Take the SAT or ACT?
Many colleges have adopted test-optional policies, but submitting strong test scores can still benefit students by:
- Strengthening applications, especially for competitive programs
- Qualifying for merit-based scholarships
- Demonstrating academic readiness
- Providing additional data points for admissions review
If your child's test scores are at or above the college's median range, submitting them is generally advantageous.
Final Recommendations
- Start with practice tests for both SAT and ACT to identify the best fit
- Focus preparation on one test for maximum score improvement
- Begin prep 3-6 months before the first official test date
- Plan to take the test at least twice (spring junior year and fall senior year)
- Work with an experienced test prep instructor to develop targeted strategies
Choosing the right test and preparing strategically can make a significant difference in college admissions outcomes. If you're unsure which test is best for your child, consider working with an experienced educator who can assess strengths, identify the best fit, and create a personalized prep plan.
