Every student learns differently, and test prep is no exception. A teen who’s a strong, confident reader might need less runway than a teen who struggles with math anxiety or test-taking stress. The goal isn’t to hit a specific grade — it’s to give your teen enough time to build both the skills and the confidence to do their best, without prep taking over their life.

That said, here’s a general timeline that works well for most families.

You don’t need to think about the SAT or ACT specifically this early — but what your teen does now still matters. Strong reading habits, solid math fundamentals, and good study routines in freshman and sophomore year all pay off later. If your teen is already struggling in core subjects like math or reading comprehension, this is the time to address it, not junior year when the pressure is on.

Think of this stage as strengthening the skills the tests will eventually measure, without the pressure of a test looming.

Many schools offer the PSAT to sophomores, and it’s a great low-stakes way to get a baseline. A practice test at this stage isn’t about the score — it’s information. It tells you and your teen:

• Which sections feel comfortable and which feel shaky
• Whether the SAT or ACT format is a better fit for how your teen thinks
• How much runway you’ll realistically want before the real test

There’s no reason to stress about this test. Treat it as a diagnostic, not a verdict.

This is when most students benefit from beginning real, structured test prep — typically 4 to 6 months before their first official test date. Junior year is the sweet spot because:

• Students have covered most of the math and grammar content the tests cover
• There’s still enough time to build skills gradually, without cramming
• It leaves room for a retake in the spring or summer if needed, without bumping into senior year application deadlines

At this stage, prep should be personalized — not just generic practice tests, but a plan built around your teen’s specific strengths and gaps. A student who’s strong in reading but nervous about the math section needs a very different plan than one who’s the opposite.

Many students take their first official SAT or ACT in the spring of junior year. This timing gives them:

• A full school year of content under their belt
• Enough prep time to walk in feeling prepared, not scrambling
• The option to retake in the summer or fall of senior year if they want a higher score — before college applications are due

If your teen wants to improve their score, the summer before senior year is an ideal window. There’s no schoolwork competing for their time, and a retake here still leaves plenty of room before early application deadlines in the fall.

By senior fall, most students are wrapping up testing and shifting focus to applications, essays, and finalizing their college list. If your teen still needs a test date at this point, it’s absolutely doable — but the runway for prep is much shorter, which is why starting the process during junior year is so valuable.

Take a breath — plenty of students start prep later than the “ideal” timeline and still do well. What matters most at any starting point is a plan that’s realistic for the time available and tailored to your teen, rather than a generic one-size-fits-all study guide. A focused, personalized approach can accomplish in a few months what an unfocused one might not accomplish in a year.

Test prep isn’t just about content review — it’s about helping your teen walk into the testing room feeling calm, capable, and prepared. Test anxiety can undo months of content review if a student doesn’t also build comfort with the format, pacing, and pressure of the actual exam. That’s why the best prep plans build in practice under realistic conditions, not just content drills.
