Duke SAT & ACT Score Requirements: What You Need to Get In (2026)

Last Updated: April 22, 2026

Key Takeaways

• Duke's admitted Class of 2029 had an SAT middle 50 of 1500 to 1570 and an ACT middle 50 of 34 to 35. SAT Math alone ran 750 to 800 for the middle of the admitted pool.
• Duke is test-optional through the 2026-2027 admissions cycle. Applicants can choose whether to submit SAT or ACT scores, and Duke states explicitly that test-optional applicants are not at a disadvantage.
• Duke superscores both the SAT and the ACT across test dates, and the ACT Science subscore is still included in the composite when present.
• Overall acceptance rate for the Class of 2029 hit a record low of 4.8 percent. Regular Decision alone was 3.67 percent, while Early Decision ran 12.8 percent.
• Duke received a record 58,712 applications and admitted just 2,818 students. ED applicants, while fewer in number (6,627), accounted for roughly 30 percent of admits.

What SAT or ACT Score Do You Need for Duke?

Duke does not publish a minimum and uses one of the most deeply holistic reviews in American higher education. What it does publish, through the Duke Office of Undergraduate Admissions, are the middle 50 percent score ranges for the Class of 2029 admitted class:

Half of Duke's admitted Class of 2029 (among submitters) scored inside those ranges. Practical target: aim for a 1540 SAT or a 35 ACT to sit comfortably in the middle. A 1500 or 34 keeps you in range. A 1570 or 36 puts you at or above most admits.

These scores are elite-level. The SAT 25th percentile (1500) is higher than the 75th percentile of virtually every public university in the country. A 1400 SAT, which is a strong score for many flagship state schools, is well below Duke's 25th percentile and would be a net negative to submit.

Duke Is Test-Optional Through the 2026-2027 Cycle

Duke's current policy, reaffirmed for the 2026-2027 admissions cycle, is test-optional for both first-year and transfer applicants. Duke states that students who apply without scores "will not be at a disadvantage in our consideration of their applications." That is not just a marketing line. Duke has admitted roughly one in three applicants without test scores in recent cycles, consistent with their admit rate from submitters.

The practical decision for an applicant is not whether Duke will penalize a missing score (it will not) but whether your specific score strengthens or weakens your file:

• SAT 1500 or higher, or ACT 34 or higher. Submit. You are at or above the 25th percentile. Scores are a genuine positive.
• SAT 1450 to 1490, or ACT 33. Judgment call. You are below the admitted 25th percentile but not by much. If your GPA, rigor, and extracurriculars are exceptional, the score neither helps nor hurts meaningfully. If those other areas have any softness, go test-optional.
• SAT 1440 or lower, or ACT 32 or lower. Go test-optional. Submitting below the 25th percentile at Duke is almost always a net negative. Your admit odds depend on the strength of the rest of the file.

Duke Superscores Both SAT and ACT

Duke is one of the more generous schools on superscoring, and the details matter for retake planning:

• SAT superscore. Duke considers the highest Reading & Writing score and the highest Math score across all of your SAT sittings, then combines them into a new superscore. You do not need a single high sitting.
• ACT superscore. Duke builds a superscored ACT composite from your best English, Math, Reading, and (when available) Science scores across dates. The Science score is still factored into the composite when present, even though Science is no longer required on newer ACT administrations.
• Scores must be within five years. If you are a returning applicant, older scores may not be accepted.
• Self-reporting is acceptable. Official score reports are only required after you enroll. Self-reported scores through the Common App are sufficient at the application stage.

Practical implication: if you are a Duke applicant with a realistic shot at the middle 50, it is almost always worth a second sitting to boost your weakest section. Superscoring means you keep the upside with none of the downside.

Duke Class of 2029: By the Numbers

Duke's Class of 2029 is the most selective admitted class in the university's history. The headline numbers, per reporting from the Duke Chronicle and Duke's admissions office:

Note the 3.5x gap between the ED rate (12.8 percent) and the RD rate (3.67 percent). That gap is larger than the gap at most Ivy-peer institutions and reflects Duke's heavy reliance on ED yield to shape its class.

Early Decision at Duke: A Real Advantage, But Binding

Duke Early Decision is binding. If admitted, you commit to enroll and withdraw all other applications. For students for whom Duke is the clear first choice, the 12.8 percent ED rate versus 3.67 percent RD rate makes ED the obviously correct choice, statistically speaking.

A few important nuances on ED:

• Binding means binding. If admitted ED, you must withdraw all other applications. The one exception is if financial aid makes Duke unaffordable, in which case you can be released from the agreement.
• Financial aid is honored. Duke meets 100 percent of demonstrated financial need for admitted students and is no-loan for families earning under $150,000. The CSS Profile and FAFSA are due November 3 for ED.
• The ED boost is real but overstated by raw numbers. The ED pool is stronger on average (recruited athletes, QuestBridge match, legacies, the most genuinely Duke-committed students), so the 12.8 percent rate is partly a selection effect. The true "ED boost" for an otherwise identical applicant is probably closer to 2x, not 3.5x.
• Do not ED if you are not sure. ED at a school you are 80 percent on can be a bad trade, because it removes the chance to compare financial aid offers in April.

What Duke Actually Weighs in Admissions

At a 4.8 percent overall admit rate, Duke can reject applicants with perfect 1600s, straight-A transcripts, and state-level awards. The file that gets admitted is almost always distinguished by something beyond raw numbers. In rough order, Duke reads for:

1. Academic rigor and depth. Not just a strong GPA, but the hardest coursework available, with a clear intellectual direction. A student who took four APs in their interest area with genuine curiosity reads stronger than one with six APs of disconnected high scores.
2. Intellectual vitality. Duke's own language for "this student would enrich a seminar discussion." The Common App essay and Duke-specific supplement are the main vehicles.
3. Meaningful extracurricular depth. One or two areas of genuine, sustained, high-level commitment beats a long list of shallow participation every time. Leadership, impact, and growth over years.
4. Personal context and perspective. Duke weighs background, family circumstances, and unique life experience as part of the "who will contribute to Duke?" assessment.
5. Teacher and counselor recommendations. Duke requires two teacher letters. Strong letters from teachers who can speak specifically to your intellectual engagement carry real weight.
6. Test scores, if submitted. Inside the middle 50, scores confirm the academic profile. Outside it, they mostly hurt.

Duke Supplemental Essays Are Load-Bearing

Duke recently redesigned its supplemental essay prompts. The 2025-2026 supplement asked applicants to respond to one required and several optional shorter prompts covering topics like "what is your sense of Duke as a place?", sexual orientation and gender identity (optional), and racial or ethnic identity (optional). The prompts are short (typically 250 words or less) but each one is read carefully.

Two rules that hold year over year:

• The "why Duke" equivalent must be specific. Generic answers that could be copy-pasted to any Ivy-peer school are a signal that the applicant did not research Duke. Name specific courses, professors, programs, or traditions.
• The optional prompts are read. "Optional" at Duke does not mean "ignored if not submitted, but not weighed heavily either." Applicants who use the optional space well often stand out, especially in the increasingly crowded RD pool.

A Realistic Prep Plan for Duke-Level Scores

If Duke is on your list and your current practice SAT is 1350 or ACT is 30, here is a rough pathway to a competitive score:

1. Sophomore spring. Take one timed official SAT and one timed ACT (via Bluebook and ACT's official practice). Identify which is your higher-percentile test.
2. Junior fall. Structured prep. Four to five hours per week plus a full timed test every two weeks. For Duke, your weakest section is the one that drags the superscore, so target it first.
3. Junior spring. First official sitting. Do not worry about a single perfect date, because Duke superscores. Focus on maximizing each section across attempts.
4. Summer before senior year. Heavy prep window. Aim for mastery of the hardest question types in your weakest section. For SAT this often means the top 20 percent of Math or the densest passage-based Reading & Writing questions. For ACT, pacing on Reading and Science is usually the blocker.
5. Fall senior year. Second and possibly third sitting. Get scores back by early October for the Duke ED deadline on November 3, or by late November for the January 5 RD deadline.

Duke Versus Peer Institutions

Here is how Duke compares to a few Ivy-plus peers that applicants frequently cross-apply to, using the most recent available class data:

Duke's profile closely tracks the Ivy-plus cohort. A candidate competitive at Duke is typically competitive at the peer group, and vice versa. The meaningful differentiators across this tier are fit, essays, and ED strategy, not raw stats.

Should I submit test scores to Duke?

Submit if your SAT is 1500 or higher, or your ACT is 34 or higher. Below those thresholds, go test-optional. The sharpest distinction is for applicants below 1450 SAT or 32 ACT, where submitting is almost always a net negative at Duke's selectivity level.

What GPA do I need for Duke?

Duke does not publish a formal GPA minimum and reports GPAs in weighted and unweighted forms that vary across feeder high schools. Practically, admitted students generally have unweighted GPAs of 3.9 or higher in a schedule loaded with AP, IB, or dual-enrollment coursework. A 4.0 unweighted is common, not exceptional, in the admitted pool.

What is Duke's acceptance rate?

Approximately 4.8 percent overall for the Class of 2029, a record low. Early Decision is 12.8 percent and Regular Decision is 3.67 percent. The 3.5x gap between ED and RD is larger than at most peer schools.

Does Duke require letters of recommendation?

Yes. Duke requires two teacher letters of recommendation and a counselor recommendation as part of the Secondary School Report. Letters from teachers who can speak to your intellectual engagement, not just your grade, matter more than letters from famous or senior teachers.

How does Duke compare to Yale or Brown?

The admitted-student academic profiles are very similar: SAT middle 50s overlap heavily at 1500 to 1580 across Duke, Yale, and Brown. Yale and Brown are now test-required; Duke remains test-optional. Duke's ED/RD admit rate gap (12.8 vs 3.67 percent) is larger than either peer, which makes ED strategy a distinguishing decision at Duke.
