The short answer: for most students, the spring of Grade 11 — March, May, or June — is the right first sitting. By then the coursework has done most of the preparation, there is still a full summer and a fall sitting in reserve, and the score arrives early enough to shape the school list instead of chasing it.
Very often I get the question from families with a Grade 10 or early Grade 11 student: should we get the first test out of the way now, or wait? The instinct to start early is understandable. Testing feels like the one part of the application with a fixed date on it, and an early score feels like progress. But a first sitting taken too early usually measures the wrong thing. It measures how much of the tested material the student has not covered yet, and it burns a Saturday that could have been spent on the coursework that actually raises the score.
Why does the spring of Grade 11 work best?
The coursework is the preparation. The SAT and ACT test reading, writing, and math that students are learning in school. By the spring of Grade 11, a student has covered most of the algebra and geometry the math sections draw on, and a year of serious reading and writing has done more for the verbal sections than any amount of drilling. A first sitting in Grade 10 tests a student on material they have not been taught yet, and the score reflects that gap.
One sitting in reserve changes the whole feeling of the test. A student who sits the test for the first time in March or May of Grade 11 still has June, the summer, and the fall of Grade 12 for a retake if the first score understates them. A student whose first sitting is the fall of Grade 12 has no room at all. The retake is not a failure plan. It is the reason the first sitting can be taken calmly, as a baseline.
The score arrives in time to shape the list. A spring Grade 11 score tells a family which schools are realistic reaches and which are solid matches before the school list is built in the summer. That is the order that works: score first, then list. A first score that arrives in the fall of Grade 12 lands after the list is already set, and it can only confirm or complicate a plan that is already in motion.
Which sitting should we pick?
March is the cleanest first date. The March SAT (March 6, 2027; register by February 19) and the February ACT (February 27, 2027; register by January 22) sit early in the spring, leave the whole rest of the year open, and fall before the heaviest stretch of the school year. A student who prepares over the winter can walk in ready and still have May and June in hand.
May works if the calendar allows it. The May SAT (May 1, 2027; register by April 16) and the April ACT (April 10, 2027; register by March 5) suit students who need the extra months of preparation. The one thing to check is the AP calendar. May is AP exam season, and a student sitting two or three AP exams in the same weeks as a first SAT or ACT is carrying two heavy loads at once. If APs fill May, take March instead and keep May for the exams.
June is the backup that still counts. The June SAT (June 5, 2027; register by May 21) and the June ACT (June 12, 2027; register by May 7) fall after most school exams, when a student can prepare without competing with coursework. June also works as a first sitting for a student who started preparation late, and as a retake date for a student whose March or May score needs one more attempt. The July ACT (July 10, 2027; register by June 4) is a further option, though it is offered at fewer test centres.
December is an option, not the default. The December SAT (December 5, 2026; register by November 20, late registration by November 24) and the December ACT (December 12, 2026; late registration closes November 29) suit a Grade 11 student whose preparation is already done and who wants a score before the winter break. For most students, December comes too soon. The preparation that would have made December a good sitting is the same preparation that makes March a better one, with more of the school year behind it.
What if my child is ahead in math and aiming for the Ivy League?
There is one exception to the spring of Grade 11 rule. It is for students aiming for Ivy League and Top 20 schools who are a year or two ahead in their math courses. Their math is already at the level the test draws on, so a first sitting in Grade 10 measures something real instead of a gap. For everyone else, the spring of Grade 11 still stands.
Take the June SAT in Grade 10 as the baseline. The June SAT (June 5, 2027; register by May 21) falls after the school year, when the student can sit it without competing with coursework. Treat the score as a baseline: it shows where the student stands before serious preparation, and it tells the family exactly which sections the summer work should target.
Then prepare intensively over the summer and sit the August test. A summer of focused preparation is the most concentrated preparation a student will ever get: no school, no other exams. The August SAT (August 28, 2027, anticipated — College Board has not yet confirmed the fall 2027 dates or posted registration deadlines) is the target sitting, and the goal is the score the student's schools expect. The August score arrives at the start of Grade 11, leaving the whole of Grade 11 and the fall of Grade 12 for a further retake if one is needed. This path is the SAT's; the ACT has no August sitting, so an ACT student in the same position would use the July test instead.
How do we choose between the SAT and the ACT?
Take a full practice test of each, under timed conditions. That is the whole method. A diagnostic taken properly — full length, timed, in one sitting — tells a family more than any description of the two tests ever will. Some students finish the ACT's faster sections comfortably and prefer its pace. Others prefer the SAT's longer time per question and its adaptive format. The right test is the one the student scores higher on and finishes with less strain, and the only way to know is to try both.
Choose by the diagnostic, then commit. Once the diagnostic points to one test, prepare for that test and sit that test. Switching late means starting preparation over for a gain that is usually imaginary. The one exception is a diagnostic that clearly favours the other test, taken early enough to prepare properly — which is another reason to run the diagnostics in Grade 10 or the fall of Grade 11, well before the first real sitting.
The ACT has changed recently. The ACT is shorter than it used to be, and science is now optional rather than a required section. That matters for a student whose strength is reading and math rather than science, and it is one more reason the diagnostic matters more than the reputation of either test.
How much preparation does a first sitting need?
Two to three months of steady work. A first sitting deserves real preparation, not a cold attempt. Eight to twelve weeks, a few hours a week, with full practice tests spaced through it, is enough for most students to walk in knowing the format, the pacing, and their own weak sections. A cold first sitting wastes the sitting and teaches the family almost nothing a practice test would not have shown for free.
Prepare for the test you are taking. SAT preparation and ACT preparation overlap, but they are different tests with different pacing. Once the diagnostic has chosen the test, the preparation should match it: timed sections, the same question types, and the same calculator and timing rules as the real thing.
Book the centre early. Test centres in Vancouver fill up, and a date on the calendar is not a seat in a room. Register as soon as the date is chosen, and check the centre list rather than assuming the nearest school will have space. A student who waits until the late registration window can find the convenient centres full and the remaining ones an hour away.
What should the first score be used for?
Treat it as a baseline. The first score answers one question: where does this student stand, with this much preparation, right now? It is the starting point for the decision about whether a retake would change anything, and it is the number the school list gets built around. It is not a verdict on the student, and it is not a prediction of where the score will end up after one more sitting.
Most schools superscore. Most universities take the best section scores across sittings, which means a retake can lift the superscore even if the total barely moves. That is the practical reason a spring first sitting works: a strong section from March and a strong section from June combine into a better score than either sitting alone.
Know the submit-or-withhold rule before the score arrives. For Canadian applicants, the rule I use is simple: submit at or above the 75th percentile of a school's published range, withhold below the 50th. A 1550 is enough, and it is no different from a 1580 in an admissions office. The full reasoning, and the score bands that decide a retake, are in the retake post linked below — the point here is that the first sitting should be judged against the schools on the list, not against a perfect score.

In summary: run the diagnostics in Grade 10 or the fall of Grade 11, choose the test by the diagnostic, prepare for two to three months, and sit the test for the first time in the spring of Grade 11 — March or May, with June in reserve. That order gives the student the coursework behind them, a retake in front of them, and a score that arrives while the plan can still use it. The one exception is the student aiming at the Ivy League who is a year or two ahead in math: June of Grade 10 as a baseline, then August after a summer of intensive preparation.
