Test-Required Is Back: MIT, Harvard, Yale, Brown, Dartmouth Reverse Course

The count is in for the 2026-27 admissions cycle, and the test-optional era is effectively over at the top of the pyramid. As of June 2026, the list of test required colleges 2026-27 covers MIT, Harvard, Yale, Brown, Dartmouth, Cornell, Penn, Stanford, and Caltech, with Princeton and Columbia set to follow for the 2027-28 cycle. That is nine of the eleven most-applied-to elite schools in the United States asking every first-year applicant for an SAT or ACT score by this fall. For students sitting Class of 2027 applications this summer, the message is simple: register for a test date, and submit the score.

The chronology of the reversal

MIT never really left. The Institute reinstated its SAT/ACT requirement in March 2022 and has held the line ever since, citing math-score predictive value for its curriculum. Dartmouth broke the Ivy dam on February 5, 2024, becoming the first Ivy League school to bring the requirement back for the Class of 2029. Yale followed within weeks with a "test-flexible" policy accepting SAT, ACT, AP, or IB. Brown and Harvard both announced in April 2024, with Harvard reversing an earlier extension of its optional policy. Caltech reinstated in April 2024 for Fall 2025 applicants.

What each school requires this cycle

For 2026-27 applications closing this fall, Harvard, Brown, Dartmouth, MIT, Caltech, and Cornell demand a straight SAT or ACT score. Yale accepts SAT or ACT (and previously allowed AP/IB under its flexible policy, which has now been tightened toward SAT/ACT specifically per its most recent update). Penn began requiring SAT or ACT for its 2025-26 cycle and continues for 2026-27. Stanford announced in June 2025 that it would reinstate SAT/ACT for applicants entering Fall 2026 onward. Cornell reinstated across its undergraduate colleges for Fall 2026 enrollment after a multiyear task-force study.

Why the test required colleges 2026 list grew so fast

The pandemic-era test-optional experiment produced five years of admissions data, and the internal reviews at Dartmouth, Yale, Brown, and Harvard reached similar conclusions. Test scores helped identify high-potential applicants from under-resourced high schools whose transcripts alone did not tell the full story. Dartmouth economists argued that going optional actually hurt access for some low-income students, because strong scores had been a credible signal admissions officers could weigh. Yale and Brown cited comparable findings. The framing changed from "tests are barriers" to "tests are one more data point that helps the reader."

What still counts as test-optional

Two Ivies remain test-optional for 2026-27 applications: Princeton and Columbia. Princeton confirmed in October 2025 that it will require SAT or ACT starting with the 2027-28 cycle, meaning current juniors applying next fall are the last cohort that can go without. Columbia Engineering and Columbia College have announced the same shift, effective August 2027. Beyond the Ivy Plus band, hundreds of liberal arts colleges and public flagships remain test-optional, but the top-ranked private research universities have converged.

How this changes application strategy for 2026-27

If you are applying to any of the nine schools above this cycle, you need a sitting on the calendar. The digital SAT runs multiple national dates through fall 2026, and the digital ACT is offered year-round in most testing centers. Register early to lock a slot before October deadlines. Aim for a submission around the 25th-percentile of your target school's admitted class as a floor; middle-50% ranges at MIT, Caltech, and Harvard sit well above 1500 SAT / 34 ACT. If you sit multiple times, most of these schools superscore, so retakes have upside. Do not skip prep on the theory that a strong GPA and rigor will carry you at these institutions in 2026-27. They will not.

Key Takeaways

• Nine of the top elite US colleges now require SAT or ACT for the 2026-27 admissions cycle, including all Ivies except Princeton and Columbia.
• Dartmouth was the first Ivy to reverse test-optional, announcing on February 5, 2024, effective Class of 2029.
• Harvard, Brown, and Yale followed with April 2024 announcements; Stanford confirmed in June 2025 for Fall 2026 applicants.
• Princeton and Columbia remain test-optional for 2026-27 but will require scores starting 2027-28.
• Applicants should register for a fall 2026 SAT or ACT sitting now and aim above the 25th-percentile of admitted class scores.

What's Next

Watch for the last few holdouts. Princeton and Columbia have already telegraphed their 2027-28 return to required testing, so current high-school juniors applying in fall 2026 are the last cohort with a genuine optional pathway at those two schools. Expect Duke, Northwestern, and Johns Hopkins to face pressure to align. For live policy pages, check each admissions office directly, since the language on "flexible," "required," and "recommended" continues to shift. The College Board's fall 2026 digital SAT calendar and ACT's year-round digital schedule are the two calendars every 2026-27 applicant should have open.
