Test-Optional Is Not Test-Blind: What the Top 15 Actually Require in 2026

Yale just ended a two year admissions experiment with a single number.

92 percent.

Hold that figure in mind.

It is the share of Yale’s fall 2026 entering class who submitted SAT or ACT scores even though the policy did not require them to. On May 27, 2026, Yale’s admissions office published the number and, in the same release, announced that starting with the 2026-27 application cycle, scores will be required again. Not optional. Not flexible. Required.

If your child is applying to a top US university this year or next, that single number is a signal. And it is part of a larger shift that has rewritten the standardized testing landscape in the last 24 months while most families were focused on essays.

Here is what changed at every top 15 university, in plain English. And here is what “test optional” actually means at the five universities still using the label.

11 schools, 24 months, one direction

In March 2022, MIT became the first elite university to bring back its SAT and ACT requirement after the pandemic moratorium. For nearly two years, almost no one followed. Then the dam broke.

Between February 2024 and May 2026, every Ivy League school except Columbia, plus Stanford, MIT, Caltech, Duke, Chicago, Northwestern, and Johns Hopkins announced or implemented a policy change. The wave, in order:

• February 2024. Dartmouth reinstates the SAT/ACT requirement.
• February 2024. Yale introduces “test flexible,” allowing AP or IB results in lieu of SAT or ACT.
• March 2024. Brown reinstates the requirement.
• April 2024. Harvard reinstates the requirement.
• April 2024. Caltech ends a four year moratorium under which scores were not visible to readers at all.
• April 2024. Cornell reinstates testing across all eight undergraduate colleges, effective fall 2026.
• August 2024. Johns Hopkins reinstates the requirement.
• February 2025. Penn reinstates the requirement.
• August 2025. Stanford reinstates the requirement.
• October 2025. Princeton announces required beginning the 2027-28 cycle.
• May 2026. Yale drops “test flexible,” returns to strict SAT or ACT.

If your child is in 11th or 12th grade right now, more than half the universities they care about have changed testing policy in the last 24 months. The press coverage has been polite. The implications have not been.

Which top universities actually require the SAT in 2026

Here is the current state at the 15 most selective US universities for the 2025-26 application cycle that just closed (Class of 2030) and the 2026-27 cycle opening this fall (Class of 2031).

A note about Caltech worth catching. From 2020 through the 2024 cycle, Caltech was not merely test optional. Submitted scores were not visible to readers at all. That is a true moratorium, functionally test blind. The April 2024 reinstatement is a bigger pivot than the headline suggests, and Caltech’s new bucket review system (A, B, and C score tiers) deserves a direct read on the admissions office’s policy page before drawing inferences from older admit profiles.

By the 2026-27 cycle, only five schools on this list remain test optional. Princeton (for one more year). Columbia. Duke. Chicago. Northwestern. The Ivy League has functionally re-aligned around a testing requirement, and Columbia is the lone permanent holdout.

The number Yale stopped hiding

Back to the 92 percent.

Yale’s two year “test flexible” experiment allowed applicants to submit AP exams or IB results in place of SAT or ACT scores. The policy was widely understood to mean that strong applicants could compete without standardized testing. The data tell a different story.

In its May 27, 2026 release, Yale disclosed that 92 percent of the entering class of 2030 submitted SAT or ACT scores even though they were not required to. The year prior, the figure was 90 percent.

Read that again. When the rule was “your call,” almost every admitted student made the same call. They submitted a score. The 8 percent who did not are not random. They are the unhooked applicants whose rest of file was strong enough to carry the absence of a score, or the recruited athletes and legacies whose admissions calculus runs on a separate track entirely.

That is the lesson this post is named for. Test optional is not test blind. When a top university says scores are optional, it usually means that scores are not required to apply but are a substantial advantage in the file. The published submission rate among admitted enrollees is a better signal than the policy label.

What “test optional” really means at the schools still using the label

Now the schools that have not yet reinstated. Here is what the data show.

Duke. The admissions office publishes that 77 percent of the most recent enrolled class submitted SAT or ACT scores. A no-score application at Duke is a minority choice. It can work, but the rest of the file has to do more work to clear the bar that scores normally clear.

Columbia. Permanently test optional since March 2023. Recent Common Data Set summaries put the SAT submission rate among enrolled students near 43 percent. The lower share suggests that, of the five holdouts, Columbia is the school at which a strong rest of file most often survives the absence of a score. Note “most often.” Not always. Not by default.

Chicago. “No Harm” policy in place since 2018. Recent CDS submission rate near 49 percent. Long established holdout. No announced change for 2026-27.

Northwestern. Test optional. Recent CDS submission rate near 46 percent. No announced change.

Princeton. Test optional for the 2026-27 cycle (the last cycle under the optional policy). Required beginning 2027-28. Rising 11th graders applying for fall 2028 will face the new requirement. Rising 12th graders this fall still have one optional cycle remaining.

If you are wondering whether your child should submit SAT scores to a test optional school, the published submission rate among admitted students is the right benchmark. At Duke (77 percent), the answer is almost always yes if your child can score in band. At Columbia, Chicago, and Northwestern (43 to 49 percent), there is more room to decide based on what the score actually says about the file.

Should your child submit SAT scores to a test-optional school

This is the question we get the most. The honest answer depends on one factor most parents get backwards.

The decision is not “do we want to submit.” The decision is “what does the score say.” A 1480 at Duke, where the 25th percentile of recent admits sits near 1500, hurts more than not submitting. A 1520 helps. The order of operations matters. Take the test. See the score. Then decide.

Families who decide “we’ll go test optional” before the test is even taken are deciding without information, which is the most expensive way to decide anything in admissions.

Three operating principles.

1. Prepare for one test, not both. Pick the SAT or the ACT based on your child’s diagnostic on each. Prepare seriously for one. Take it early in 11th grade. Retake once if needed. Stop.
2. Target the band, not the median. The score that matters is the one at the 25th to 75th percentile band of admitted students at the schools your child is targeting. The MIT mid 50 SAT is roughly 1520 to 1570. The Penn mid 50 is roughly 1510 to 1570. “I just want a 1500” is not a target. “I want a 1520 or above for MIT” is.
3. Decide submission after the score is in hand. Never before.

What to do in the next 60 days

If your child is applying in the 2026-27 cycle, the policy environment is now settled enough to plan around. Four moves.

Move 1. If any school on your child’s list is in the required column above, your child needs an SAT or ACT score. There is no further decision to make. Pick the test, prepare seriously, take it early.

Move 2. If your child is applying to a test optional school (Duke, Columbia, Chicago, Northwestern, or Princeton), do not treat “optional” as a license to skip the test. Take it. Then decide submission based on the score in hand and the published submission rate at each school.

Move 3. Do not apply test optional as test avoidance. The argument for a no-score application is rare and specific. It requires a transcript and a profile so demonstrably rigorous (IB Diploma with multiple 7s in HL, the most rigorous schedule the high school will allow, two years of post-AP coursework, evidence-grade external work) that the score would not move the file. Most candidacies do not meet that bar. The honest move is to test.

Move 4. If your child is in 9th or 10th grade, plan for required. The policy environment for the 2027-28 cycle and beyond is still moving. Princeton’s transition is locked in. Columbia, Chicago, Duke, and Northwestern could move next. Plan around testing being required and be pleasantly surprised by the schools that hold the line.
