Test-Required vs Test-Optional: How US College Testing Policies Changed for 2026–27

For the 2026–27 admissions cycle (fall 2027 entry), US colleges fall into two camps. A test-required college won’t review an application without an SAT or ACT score. A test-optional college lets the applicant decide whether to send one. This cycle, six of the eight Ivy League schools require scores, and so do MIT, Caltech, Stanford and Georgetown. Princeton and Columbia stay test-optional for one final cycle. Across the country, FairTest’s August 2026 count puts 2,021 of 2,182 four-year colleges with confirmed policies (92.6%) as test-optional or test-free for fall 2027.

So does a Grade 12 student in Hanoi still need an SAT score? That depends on her college list. If even one college on it is test-required, she needs a score, unless that college grants her a hardship waiver. If every college is optional, sending a score is a strategic choice.

Start by listing each target college’s policy for your exact cycle. This guide gives you the policy map, the reasons behind it and a submit-or-skip decision table. It ends with the True North Testing Compass, a four-step checklist a family can fill in tonight, drawn from the university counseling work of True North International School in Hà Đông.

What do test-required, test-optional, test-flexible and test-blind mean in 2026–27?

Each label tells you what a college does with an SAT or ACT score: requires it, lets you choose, accepts a substitute, or ignores it. Four labels cover almost every US college in 2026–27. A college can switch labels from one cycle to the next, so always read the policy for your own cycle.

Each admissions cycle lines up with one entry term and one graduating class. The 2026–27 cycle means applying in fall 2026, starting college in fall 2027 and joining the Class of 2031. A policy announced “for fall 2028 entry” therefore applies to today’s Grade 11 students, not to Grade 12.

In True North International School’s counseling experience, selective US colleges read a score alongside the transcript, essays, recommendations and activities. The test policy simply decides whether the score is in that pile at all.

Which colleges are test-blind and ignore SAT scores entirely?

The University of California system is the best-known test-blind group. UC campuses do not consider SAT or ACT scores, even when an applicant sends them. In 2026, UC faculty members published an open letter urging the system to bring testing back for STEM admissions, citing gaps in incoming students’ math skills. The letter is a call for change, not a policy change, so UC stays test-blind until the system itself announces otherwise.

First step: write “2026–27 = fall 2027 = Class of 2031” at the top of your college list before you check a single policy.

Which US colleges require the SAT or ACT for the 2026–27 cycle?

For fall 2027 entry, Harvard, Yale, Dartmouth, Brown, Cornell and Penn require the SAT or ACT. MIT, Caltech, Stanford, Georgetown and Johns Hopkins require scores too, as do several public flagships, including UT Austin, Georgia Tech, the University of Florida and Ohio State (Columbus).

Two Southern publics join the required list this cycle: Auburn and LSU require scores from fall 2027 entry. Vanderbilt follows on a slower clock. It stays test-optional for students entering in fall 2027 and fall 2028, then requires scores beginning with its fall 2029 admissions cycle.

Is Princeton still test-optional for fall 2027 entry?

Yes. Princeton is test-optional for students applying in the 2026–27 cycle. On October 9, 2025, Princeton’s Office of Admission announced that SAT or ACT scores will be required again from the 2027–28 cycle, for fall 2028 entry. A Grade 12 student applying now can choose. A Grade 11 student won’t have that choice.

When does Columbia start requiring the SAT again?

Columbia College and Columbia Engineering require the SAT or ACT from August 2027, for the 2027–28 admissions cycle. Columbia announced the change on June 12, 2026, after a multi-year faculty review. Both schools stay test-optional for the 2026–27 cycle, so this year’s seniors can still apply without a score.

Can AP or IB scores still replace the SAT at Yale?

No. On May 27, 2026, Yale announced that every first-year and transfer applicant in the 2026–27 cycle must submit an SAT or ACT score. That ended Yale’s test-flexible policy, under which AP or IB results could meet the requirement. IB Diploma and AP students can still add those results to the academic record, but they no longer count toward the testing requirement on their own.

Bottom line: if your list includes Yale, Harvard, MIT, Stanford or Georgetown, an official SAT or ACT score is a deadline item, not an option.

Why did selective colleges bring testing back?

Two reasons are on the record. Columbia pointed to a multi-year faculty review, which described scores as a useful indicator of student success. Yale changed course after most of its applicants were already sending scores. Those are the reasons the colleges and their summaries give; they don’t rule out other factors behind the timing of each decision.

Yale’s case shows the second reason most clearly. Under its test-flexible policy, roughly 90% of Yale applicants submitted SAT or ACT scores, according to Oriel Admissions’ summary of Yale’s May 2026 announcement. Applicants and admission officers also found AP, IB, SAT and ACT results hard to compare side by side. At Yale, at least, “optional” worked more like “expected” for nine in ten applicants.

Dartmouth researchers reported a related finding in a January 2025 NBER working paper. Under test-optional rules, high-achieving applicants from less advantaged backgrounds submitted scores at too low a rate. The researchers estimated that these applicants’ admission probability at Dartmouth rose 3.6 times, from 2.9% to 10.2%, when they reported their scores. The study covers one college, and students who chose to submit may differ from those who didn’t in ways a score doesn’t capture.

Applicants have moved the same way. In Common App’s 2025–26 season report, 779,300 first-year applicants reported a score, up 11%, while 748,028 applied without one, down 5%. By March 1, 2026, about 52% of Common App applicants had submitted scores, the first majority since before the pandemic. These figures describe a change in reporting, not proof that reporting a score caused any admission.

Testing has come back mainly at the top. FairTest tracks national policy counts, and its August 2026 release shows about nine in ten US four-year colleges still do not require scores for fall 2027. Some research reports no meaningful change in graduation rates after colleges went test-optional [CẦN NGUỒN: named studies]. On FairTest’s count, the accurate headline is “the SAT is back at the most selective colleges”, not “the SAT is back”.

What this means for your list: if it’s built around Ivy Plus schools, plan for a strong score; if it centers on mid-selectivity colleges, treat the SAT as one option among several.

Does test-optional apply to international students from Vietnam?

Each college decides whether its test-optional policy covers international applicants, so read the international applicant page, not just the main admissions page.

For Vietnamese families, this is not a niche question. IIE Open Doors 2025 counts nearly 25,600 Vietnamese students at US higher education institutions in 2024–25, up 16% year on year and the highest number on record. That figure puts Vietnam fifth among source countries, up from 22,066 students in 2023–24.

A US admissions reader may not know how to weigh a transcript from a Vietnamese school. True North International School’s counselors see the SAT as a shared reference point: it sits next to a grading scale the reader may not know. Contextual review means the admissions office reads the score in light of the applicant’s school and background. That is why True North’s counselors often advise sending a strong but not perfect score from a Vietnamese applicant.

Do I still need IELTS or TOEFL if I submit an SAT score?

Plan for yes until a college’s international page says otherwise. An English test such as IELTS, TOEFL iBT or the Duolingo English Test is a separate requirement, and each college sets its own waiver rules . A high SAT Reading and Writing score doesn’t automatically replace the English test, so check each college’s waiver rules before dropping one. For a Vietnamese family, True North’s counselors frame the real decision as two tests or one, and that choice shapes the whole Grade 11–12 calendar.

[[EDITOR | LƯU Ý: Check each college’s English-test waiver rules on its international page before dropping IELTS, TOEFL or Duolingo from the plan.]]

The check that matters: before you cut the SAT from the plan, confirm that every college on the list will accept the English test alone.

Should you submit an SAT score below a college’s middle 50%?

Decide college by college, using each college’s published middle 50% range from its Common Data Set. True North International School’s approach is to skip any blanket “submit” or “don’t submit” rule, because one rule for the whole list can waste a good score at one college and expose a weak one at another.

Context can shift the last two rows. In the Dartmouth study, admissions officers read scores against each applicant’s background, so a score near the 25th percentile could still help an applicant from a less-resourced school. That finding comes from one college. Use it to inform your judgment, not as a rule for every college on your list.

What SAT score is competitive for the Ivy League in 2026?

Ivy League colleges publish their middle 50% SAT ranges in each year’s Common Data Set. One real benchmark comes from Hanoi: International Program students at True North International School scored 1550/1600 in 2023 and 1570/1600 in 2024. The school’s first Grade 12 class received offers from more than 30 international universities, including Cornell, and US$3,000,000 in US scholarships. These results describe one cohort and don’t show which score each admission required.

Does not submitting scores affect merit scholarships or financial aid?

It depends on each college’s scholarship policy. Some test-optional colleges state that non-submitters remain eligible for merit scholarships, while others use scores in scholarship review. Read the scholarship page as well as the admissions page before you decide to withhold a score.

The takeaway: put each college’s 25th and 75th percentile next to the student’s score, decide one college at a time, and check the scholarship page separately.

Is it too late for a Grade 12 student to take the SAT in December 2026?

Not necessarily. Whether a December 5, 2026 score counts depends on each college’s last accepted test date for Regular Decision, September 12, October 3, November 7 and December 5, 2026, then March 6, May 1 and June 5, 2027.

For a Grade 12 student in early November 2026, the squeeze is real: an Early Decision or Early Action deadline has just passed or is days away, and she has no score. At Princeton or Columbia this cycle, she can still apply test-optional. At Yale, Harvard or MIT, she needs a score that reaches the college before the relevant deadline.

[[EDITOR | PRO TIP: Book the next SAT sitting the same day you confirm each college’s last accepted test date and its deadline for receiving official scores.]]

Where can I take the SAT in Hanoi or Ho Chi Minh City, and how much does it cost?

IIG Việt Nam runs SAT sittings in Vietnam under College Board authorization, with test centers concentrated in Hanoi and Ho Chi Minh City. The test is the Digital SAT. Dates can move around public holidays: in 2026, IIG moved the May SAT in Vietnam to May 16, after the 30 April–1 May holiday. The fee for international test takers changes over time.

Is the SAT or the ACT better for Vietnamese students?

The colleges named in this guide accept either the SAT or the ACT to meet their requirement. What decides it is test center access in Vietnam and which format suits the student. Superscoring combines the best section scores across sittings, so a second sitting of the same test can raise the reported score at colleges that superscore.

Do this today: book the next available sitting, and check each college’s last accepted test date the same day.

Should a Grade 11 student take the SAT now, even if target colleges are optional?

Yes. A Grade 11 student applies in the 2027–28 cycle, and on announcements made as of November 2026, all eight Ivy League schools will require scores that cycle. True North International School recommends one official SAT or ACT sitting by the end of junior year, so the full US list stays open whether a college moves to test-required or stays optional.

2026–27 is a “split year”: siblings one grade apart face different rules at the same colleges.

Expat families moving to Hanoi mid-year face an extra timing problem, because a move can interrupt test prep, AP courses and test dates. True North International School covers this case in its guide to an SAT and AP testing plan for a mid-year move.

Cost and workload shape the plan as much as policy does. At True North International School, AP courses are included in International Program tuition, while the Bilingual Program charges 18 million VND per AP subject. That lets a family put AP exams, an English test and one SAT sitting on a single Grade 11 calendar.

The target: one official sitting before the end of junior year, with the fall of Grade 12 kept free for one retake.

The True North Testing Compass: a 4-step checklist for families

The True North Testing Compass is a college-by-college worksheet that tells a family whether to test, submit or skip. It turns the policy map above into four decisions, and a family can finish it in one evening with the college list open.

[[EDITOR | MODULE: True North Testing Compass worksheet — families enter each college’s policy, middle 50% range, student score and English-test rule to get a submit/skip suggestion.]]

Step 1 — Map the policy for your exact cycle.

• Write each college’s policy for 2026–27 or 2027–28.
• Flag any college that changes policy next cycle.
• Note any test-flexible substitutes.

Step 2 — Find the strictest requirement on the list.

• One test-required college means the student must test.
• Note that college’s last accepted SAT date.

Step 3 — Compare the score with each middle 50%.

• Pull the 25th and 75th percentile from each Common Data Set.
• Apply the decision table in the middle 50% section.

Step 4 — Check the non-negotiables.

• English test requirement and minimum score.
• Scholarship and merit-aid testing rules.
• Hardship waiver options, if test access is a problem.

In short: the strictest requirement on the list sets the testing plan, and the middle 50% decides submission at every other college.
