Most students should take the SAT or ACT for the first time in spring of junior year (March, May, or June). This provides results before summer, time to retake in the fall if needed, and a final opportunity in October (for EA/ED deadlines) or December (for Regular Decision). Take the PSAT/NMSQT in October of junior year for National Merit Scholarship eligibility.
Testing timing significantly affects both your scores and your options. Here is the optimal testing calendar.
Junior Year Testing Calendar
October junior year: PSAT/NMSQT — take this no matter what. It determines National Merit Scholarship Semifinalist eligibility. March/April junior year: First SAT attempt for most students. You'll have studied, have enough academic preparation to perform well, and can see results before summer. May/June junior year: Good for first ACT attempt or second SAT attempt. Results arrive before summer. Summer before senior year: Review results and decide whether to retake. Targeted preparation for fall retakes.
Senior Year Testing Calendar
August/September senior year: Optional retake if you want to improve scores. October senior year: Last test date that EA and ED applications can typically use. Scores usually available before November 1 deadlines. November/December senior year: Last dates for Regular Decision applications. Score availability depends on test date and school processing timelines — check each school's policy.
How Many Times to Take
2–3 times is typical. Most students see meaningful improvement from first to second attempt — the testing format itself is familiar. Improvement from second to third attempt is more variable and often smaller. More than 3–4 attempts produces diminishing returns and can raise questions about testing strategy.

Taking the SAT or ACT 2–3 times is normal and expected. Taking it 5+ times can raise eyebrows at some schools that require all scores — and diminishing returns on score improvement make multiple attempts less productive. 3 attempts is typically the maximum worth pursuing unless you have specific circumstances.
