SAT and ACT Test Dates: The Calendar, Reverse Engineered From Application Deadlines
By Rona Aydin
TL;DR: The SAT is offered on eight national dates each cycle, typically in August, September, October, November, December, March, May, and June, with registration closing roughly four to five weeks before each sitting. The ACT runs its own seven date calendar, typically September, October, December, February, April, June, and July, and the redesigned ACT now treats the science section as an optional add on. For applicants at test required colleges, the working rule is simple: the October sitting is the last comfortable date for November 1 early deadlines, and December is the practical ceiling for Regular Decision. Exact dates are published by College Board and ACT each spring and should be confirmed there before registering.

The Testing Calendar, Reverse Engineered From Deadlines
Test dates only matter relative to two walls: November 1, when nearly every Early Decision and Early Action application closes, and the January Regular Decision deadlines. Work backward from those and the calendar plans itself. A first official sitting in the spring of junior year leaves room for a summer of targeted preparation; the August SAT or September ACT serves as the primary retake; October is the final sitting whose scores reliably reach early applications; and December exists as the last chance lane for Regular Decision, tight but workable at most schools that accept scores arriving shortly after the deadline.
The return of test requirements raised the stakes on this arithmetic. With Harvard, Yale, Brown, Dartmouth, Cornell, Penn, Stanford, MIT, Caltech, and Georgetown all requiring scores, a missed October sitting now closes early doors rather than merely weakening a file. Our full policy table in which colleges require the SAT and ACT maps the requirement landscape school by school.
Typical SAT and ACT National Test Dates
The pattern below has held across recent cycles; College Board and ACT publish the exact dates for each year on their official calendars, and international administrations follow a partially different schedule.
| Month | Test | Where It Fits in an Application Timeline |
|---|---|---|
| August | SAT | Primary senior retake before early deadlines |
| September | SAT and ACT | Primary senior retakes; the September SAT is the newest date on the calendar |
| October | SAT and ACT | Last comfortable sitting for November 1 applications |
| November | SAT | Scores generally too late for early rounds; fine for RD |
| December | SAT and ACT | Practical ceiling for Regular Decision scores |
| February | ACT | RD arrival varies; confirm per college |
| March | SAT | Ideal first official sitting for juniors |
| April | ACT | Junior year first sitting or spring retake |
| May | SAT | Junior spring sitting; watch AP exam collisions |
| June | SAT and ACT | End of junior year benchmark |
| July | ACT | Summer sitting before senior fall |
Registration Windows, Score Delivery, and the Details That Bite
Registration closes roughly four to five weeks before each sitting, with a short late window carrying an extra fee, and popular metropolitan test centers fill well before the deadline, which is its own reason to register the day plans firm up. Scores return in about two weeks for the digital SAT and two to eight weeks for the ACT, and score sends to colleges add processing days on top, which is why the October sitting sits so close to the November 1 edge: the math works, but only without accidents. Students using fee waivers should also note that the waiver bundles free score sends, an easy hundred dollars of savings left unclaimed every cycle.
Two collisions deserve advance planning. The May SAT lands inside AP exam season, a brutal week to add a four hour test, which is why March remains the cleaner junior sitting. And summer ACT and August SAT dates precede senior year course loads, making them the highest leverage retakes on the calendar: full preparation time, zero schoolwork competition.

Frequently Asked Questions About SAT and ACT Test Dates
The SAT is typically administered on national dates in August, October, November, December, March, May, and June each cycle. College Board publishes the exact Saturday dates on its official calendar, and international administrations follow a partially different schedule.
The October sitting is the last comfortable SAT for November 1 Early Decision and Early Action deadlines, since scores return in about two weeks. Some colleges accept November scores for early rounds, but that depends on each school’s stated policy and leaves no margin for error.
Regular registration closes roughly four to five weeks before each test date, with a late registration window carrying an additional fee. Popular test centers fill earlier than the deadline, so registering as soon as plans firm up protects both the date and the location.
March of junior year is the cleanest first official sitting: coursework has covered the content, AP season has not yet arrived, and the result leaves a full summer for targeted preparation before the high leverage August retake.
Two to three official sittings is the productive range for most strong applicants: a junior year baseline, a prepared summer or early fall retake, and an optional third sitting if a specific section target remains. Diminishing returns and application season workload argue against more.
Usually yes. December SAT and ACT scores return before most January deadlines, and many colleges accept scores that arrive shortly after the application deadline. The policy varies by school, so December testers should confirm each college’s latest accepted date directly.
