When Should My Child Start SAT Prep? (2026-27 Test Dates)
The short answer: pick the test date first, then count backwards. Most families do it the other way round, start preparing at some vague point, and end up booking whichever date happens to be next.
Here is the calendar, then the method.
SAT dates and registration deadlines, 2026–27
Registration deadlines are the part people miss. All deadlines close at 11:59 p.m. Eastern.
November 7, 2026 — register by October 23 (late registration October 27)
December 5, 2026 — register by November 20 (late registration November 24)
March 6, 2027 — register by February 19 (late registration February 23)
May 1, 2027 — register by April 16 (late registration April 20)
June 5, 2027 — register by May 21 (late registration May 25)
The August, September and October 2026 dates have already passed.
Note the gap. There is no SAT in January, February or April. Between December 5 and March 6 there is a three-month stretch with no test at all. Families who assume they can "just take the next one" in January are often surprised.
Schools also run SAT School Day administrations, where the school registers students directly. Spring 2027 School Day testing runs March 1 to April 30. Ask your counsellor whether your school participates, because it can be a free additional sitting.
Work backwards, not forwards
Choose the date your child will sit, then count back.
Twelve weeks out: take a real diagnostic. Not a guess at a score, an actual timed test. You cannot plan preparation for a number you do not have, and most students are somewhere other than where they assume.
Ten to twelve weeks out: start structured work. This is the sweet spot for most students. Long enough to fix genuine weaknesses, short enough that the student stays engaged. Preparation that drags on for six months usually produces three months of effort and three months of resentment.
Four weeks out: shift to full timed sections. Content work gives way to pacing, stamina and decision-making under pressure.
Two weeks out: stop learning new material. Review errors, hold the routine, protect sleep.
So when in high school?
For most students aiming at competitive colleges:
Sophomore year is for the PSAT and for building the underlying maths and reading skills. Formal SAT prep this early tends to waste effort, because the content has not all been taught yet.
Junior year is the main event. Most students sit the SAT for the first time in the spring of junior year, often March or May, with a second attempt in the summer or early autumn. That timing leaves room to improve without colliding with application deadlines.
Senior autumn is the backstop, not the plan. The November and December dates work if a student needs one more attempt, but by then applications are in motion and the schedule is unforgiving.
How long does improvement actually take?
Honest version: it depends on the gap between where a student is and where they want to be, and on how consistently they work.
A student moving from 1300 to 1400 is doing something very different from a student moving from 1450 to 1550. The first is usually fixing recurring errors. The second is eliminating rare ones, which takes longer per point.
Across our students, meaningful improvement typically comes from ten to twelve weeks of consistent weekly work, and many see gains of 100 to 200 points. Results vary by student, and anyone promising you a specific number is selling rather than teaching.
The mistake worth avoiding
Sitting the test cold "to see what happens."
It sounds sensible and it usually is not, for two reasons. The score goes on a record your child may later have to decide whether to report. And the information you get is no better than a free practice test taken at home, which costs nothing and carries no consequences.
If you want a baseline, take a diagnostic. If you want a score, prepare first.
What to do this week
Pick the target date from the calendar above and check its registration deadline. If November 7 is the plan, that deadline is imminent.
Get a baseline. Our free 30-minute Mini SAT Diagnostic returns an instant score report broken down by question type, so you can see where the points actually are.
Count backwards from the test date using the twelve-week structure above and put it in the calendar properly, around sport, exams and everything else competing for the same hours.
