When to Take the SAT or ACT Test? 

Choosing the right test date for the SAT or ACT isn’t just a scheduling decision—it’s a strategy move. The timing of your exam affects how well you perform and how smoothly your college applications go. We will give you some recommendations to help you make the best decision.

What Are the Key SAT and ACT Test Dates for 2025?

Below is an at-a-glance calendar of confirmed and projected test dates for 2025 so you can map out your year strategically.

*August SAT is typically digital only and may not be offered internationally.

How to Choose Between the SAT and ACT?

Both tests are accepted by every major college in the U.S., so the choice comes down to your strengths. Key differences:

Legacy offers diagnostic assessments to help students figure out which test suits them better before they commit to one.

When Is the Best Time to Take the SAT or ACT?

For most students, the spring of junior year (11th grade) is the ideal time to take their first test. Why spring works:

• You’ve learned most of the tested content
• You still have time to retake if needed
• Scores arrive in time for early application deadlines

If you’re aiming for early action or early decision, testing by August or October of senior year is the latest you should wait.

“I strongly suggest taking at least one SAT during junior year. My preference is the March date because you’ve got a relatively easy 2-3 month runway leading up to it for studying, and you’re done with the test before APs and finals in April/May/June. That also leaves plenty of extra tests in the fall for retaking it, since most people will take the SAT more than once”

When to Start Prepping Based on Your Test Date?

The best time to start prepping for the SAT or ACT depends entirely on your test date—and your goals. If you’re aiming for a highly competitive score or applying to top-tier schools, starting early gives you a major advantage. Most students see the best results when they allow themselves at least three to six months of prep time.

Let’s say your test is in June. That means your ideal prep window starts in February or March. Starting this early gives you enough time to take a diagnostic test and set up a weekly study routine. On the other hand, if your schedule is packed with classes or extracurriculars, you may need to spread your prep across more weeks with fewer hours per session. That’s okay—just be consistent. Even 30-45 minutes a day can make a difference if you stick to it over time.

How to Prepare for the SAT or ACT Efficiently?

Efficiency isn’t about how long you study—it’s about how smart you study. Best practices:

• Use official practice tests to understand the format
• Focus on your weakest sections first for fastest gains
• Use tools like the Bluebook app (for SAT) and ACT’s online prep portal
• Work with a tutor if you’re plateauing or aiming for high scores
• Track your mistakes and create a log of error patterns

Legacy students often raise their scores by 100+ points on the SAT and 4-6 points on the ACT with structured, personalized prep.

“I did a practice section every day (starting 2 weeks before the test)… I would alternate between reading and writing, but really just drill your weak points till you have none!”

What If You Need to Retake the SAT or ACT?

If your first score didn’t reflect your actual ability—maybe you were sick or didn’t have time to prepare properly—the next attempt gives you a second chance. It also allows you to apply the strategies you’ve learned through practice and experience. Studies show that students often improve their scores on a second or third try, particularly if they spend time reviewing their results and targeting weak areas.

However, there are a few important things to consider. First, know the deadlines. If you’re retaking the test for a specific college or scholarship deadline, make sure there’s enough time for scores to be processed and sent. Also, keep an eye on test date availability—some dates fill up quickly, especially in major cities.

Finally, don’t rush into a retake just because you’re disappointed. Ask yourself: What will I do differently this time? Whether that means joining a test prep course or working with a tutor, make sure your next attempt builds on what you’ve already learned.
