SAT and ACT 2026-2027: What You Need to Know

If you are applying to US universities for Fall 2027, two dates matter this week: registration for the October 3, 2026 SAT closes tomorrow, on September 18, 2026, and late registration for the October 17, 2026 ACT is still open until September 29. Here is the full, officially verified SAT and ACT calendar for the 2026-2027 school year.

Why the SAT and ACT calendar matters this early in the year

An increasing number of US universities have reinstated standardized testing requirements after the test-optional years, and most expect a score before the Early Decision or Early Action deadline of November 1, or before the Regular Decision deadline of January 1 through the Common App. For applicants targeting Early Decision, the October sitting is often the last comfortable option: SAT scores are released within 2 to 4 weeks, ACT scores on a similar timeline, which leaves just enough room to finalize the application before November 1.

The official College Board calendar for 2026-2027, international sittings included:

• October 3, 2026: register by September 18, 2026; changes and late registration by September 22, 2026
• November 7, 2026: register by October 23, 2026
• December 5, 2026: register by November 20, 2026
• March 6, 2027: register by February 19, 2027
• May 1, 2027: register by April 16, 2027
• June 5, 2027: register by May 21, 2027

The August 22 and September 12 sittings are already closed for standard registration. For a 2027 application, the October or November sitting is the one most international applicants still use.

The official ACT.org calendar for the same year:

• September 19, 2026: registration closed (regular deadline was August 14, late deadline September 1)
• October 17, 2026: late registration still open until September 29, 2026 (regular deadline of September 11 has passed)
• December 12, 2026: register by November 6, 2026
• February 27, 2027: register by January 22, 2027
• April 10, 2027: register by March 5, 2027
• June 12, 2027: register by May 7, 2027

Late registration comes with an extra fee, but it is often the only way to catch a sitting you nearly missed, which is exactly the situation this week for the October 17 ACT.

SAT or ACT: which one should you take?

Both tests carry equal weight with almost every US university, which use official concordance tables to compare the two scales. The real difference is format: the SAT, fully digital since 2024 on the Bluebook platform, is adaptive and shorter; the ACT still offers a paper or digital option and includes a dedicated science section that tends to suit math and science-oriented students better. The most reliable way to choose is a full practice test on each side, not reputation.

How to plan your test dates properly

Three simple rules to build a safe calendar:

• Plan for at least two sittings before your application deadline, so you can retake the test if the first score is not where you want it. Most universities accept superscoring, combining your best section scores across multiple sittings.
• Allow 2 to 4 weeks for score release before you can send results to universities.
• Check that your chosen test center still has open seats: the most popular international centers fill up weeks before the registration deadline.

Structured SAT preparation helps build a realistic study plan around these dates instead of registering under time pressure.

Is the SAT required for every US application?

No. A number of universities, including several Ivy League schools, remain test-optional or test-blind depending on the program, while others, notably the most selective public universities and several engineering programs, reinstated the requirement starting in 2024. The exact policy must be checked school by school and program by program on each university’s official admissions page, since it can change from one cycle to the next.

Can you retake the SAT or ACT more than once?

Yes, there is no official limit on attempts, though most applicants cap it at two or three sittings to stay credible with admissions offices. That is exactly why planning ahead matters: locking in your sittings early avoids the scramble some students are facing this week to still catch the October 17 ACT.

Do you need to take both the SAT and the ACT?

In most cases, no. Universities give no extra credit for submitting both scores instead of one. It is far more effective to focus preparation on a single, well-chosen test than to split study time across two different formats.
