SAT vs ACT: Which Test to Take and When

Standardized testing remains one of the most stressful parts of college admissions. The good news is that you have choices, and most schools accept either the SAT or ACT without preference. Plan your testing around the rest of the process with our college application timeline.

Know the differences

• SAT: Emphasizes reading comprehension, algebra, and data analysis. Slower pacing. No science section.
• ACT: Emphasizes speed, grammar, and interpretation of charts and experiments. Includes a science reasoning section.
• Both: Offer optional essay sections that few schools require.

Take a practice test of each

The best way to choose is data, not intuition. Sit for a timed, full-length practice test of each under realistic conditions. Compare scores using the official concordance table. Pick the one where your percentile is higher.

When to take it

Plan your first official test for spring of junior year. This gives you time to retake in the summer or fall of senior year if needed. See the full junior year timeline for how testing fits with everything else. Avoid taking tests back to back without studying between attempts.

How many times is too many

Two to three attempts is the sweet spot. After that, score improvements usually plateau and the time is better spent on essays or extracurriculars. Some schools require you to send all scores. Others allow superscoring.

Superscoring and score choice

Superscoring combines your best section scores across test dates. Score Choice lets you select which dates to send. Know each school’s policy before you register.

Test-optional does not mean test-blind

If your scores are at or above a school’s middle 50%, submitting them usually helps. If they are well below, test-optional may be your friend. Research each school’s published data.
