WashU Early Decision Acceptance Rate: 27.0% Through Two Binding Rounds, Plus a New Early Action Path
By Rona Aydin
TL;DR: The WashU Early Decision acceptance rate was 27.0% for the Class of 2029, with 1,333 students admitted from 4,934 binding applications across ED I and ED II, against 9.3% for applicants outside the binding rounds and an 11.9% overall rate (Washington University in St. Louis Common Data Set 2025-2026). That 2.9x edge can fill up to two thirds of the 1,961 enrolled seats. WashU now runs the most complete early menu among top 25 privates: binding ED I (November 2, decisions December 11), binding ED II (January 4, decisions February 12), and a new nonbinding, nonrestrictive Early Action round (November 2, decisions December 23). Testing is optional, and WashU packages aid without loans for every student. For families weighing the early paths at WashU, Oriel Admissions builds the round strategy around your student’s specific position: schedule a consultation.
What Is the WashU Early Decision Acceptance Rate?
The WashU Early Decision acceptance rate for the Class of 2029 was 27.0%: 4,934 students applied through the two binding rounds and 1,333 received offers, per the university’s Common Data Set 2025-2026. Applicants outside the binding rounds were admitted at 9.3%, with 2,635 offers from 28,349 applications, and the blended overall rate was 11.9% on 33,283 total applications. Nearly three of every ten binding applicants received an offer, one of the widest published gaps between early and regular odds among top 25 private universities, and every figure in this guide comes from the audited filing.
| Round (Class of 2029) | Applications | Admits | Acceptance Rate |
|---|---|---|---|
| Early Decision (I + II combined) | 4,934 | 1,333 | 27.0% |
| Outside binding rounds | 28,349 | 2,635 | 9.3% |
| Overall | 33,283 | 3,968 | 11.9% |
WashU has not released Class of 2030 round data, so the current cycle’s rate will only be computable when the next Common Data Set is filed.

Three Early Paths, Two of Them Binding: The New WashU Calendar
The structural news in the 2025-2026 filing is a third early path. Alongside its two binding rounds, WashU now reports a nonbinding Early Action plan, closing November 2 with decisions on December 23, and the filing states explicitly that the plan is not restrictive, so students may apply to other early programs at the same time. Binding ED I closes November 2 with decisions on December 11, binding ED II closes January 4 with decisions on February 12, and Regular Decision closes January 4 with notification by April 1 and a May 1 reply date. The strategic split is clean: Early Action buys a December answer without commitment, while Early Decision converts commitment into the 27.0% rate, and WashU lists applicant interest as a considered factor, so the binding signal carries real weight. Choosing between the second binding window and the regular pool is a calculus we map in our Early Decision II strategy guide.
| Round | Application Deadline | Notification | Binding |
|---|---|---|---|
| Early Decision I | November 2 | December 11 | Yes |
| Early Action (new, nonrestrictive) | November 2 | December 23 | No |
| Early Decision II | January 4 | February 12 | Yes |
| Regular Decision | January 4 | By April 1 | No |
A 2.9x Multiplier That Can Fill Two Thirds of the Class
At 27.0% against 9.3%, the WashU Early Decision acceptance rate runs about 2.9 times the rate outside the binding rounds, and the seat arithmetic is even more aggressive than the multiple. The 1,333 binding admits, nearly all of whom enroll by definition, can account for up to 68% of the 1,961 enrolled first year seats, which would leave the Regular and Early Action pools competing for roughly a third of the class at 9.3% odds. Unlike Rice, WashU does not disclose how many binding admits actually enrolled, so the true share sits somewhat below that ceiling after aid releases and melt, but the direction is unambiguous: the class is substantially built in the binding rounds. The usual caveats apply, recruited athletes and institutional priorities concentrate in the early pool, so the true like for like advantage for an unhooked applicant is smaller than the raw numbers; our Early Decision versus Regular Decision guide covers how to discount published gaps, our ED versus RD acceptance rate comparison shows where WashU’s 2.9x sits among peers, and our ED versus RD advantage calculator lets you model the arithmetic for a specific profile.
Testing, the No Loan Policy, and the Binding Commitment
Two policy facts should shape any early application to WashU. First, testing: the filing states that WashU has adopted a test optional policy and that all applicants receive full consideration whether or not they submit scores. The submission math is elite even by top 25 standards: 32% of enrolled first years submitted an SAT with a middle 50% of 1500 to 1550, and 29% submitted an ACT at a 33 to 35 middle 50%, so a score inside those bands strengthens a binding file and a score below them is usually better withheld. Second, money: WashU meets 100% of demonstrated need and has eliminated loans from every undergraduate aid package, not only for low income families. The WashU Pledge makes attendance free for first year students from Missouri and southern Illinois families earning $75,000 or less, home equity is excluded from the need analysis, and the average first year aid package was $81,871. The aid calendar is built for the binding rounds: ED I aid materials are due November 17 with the aid decision arriving alongside admission on December 11 and a January 4 reply date, so a family sees its full price before committing, and WashU’s own net price calculator lets you model it before November 2. The recognized release from an ED agreement remains an aid award that does not make attendance feasible, mechanics we cover in Early Decision and financial aid.

Frequently Asked Questions About the WashU Early Decision Acceptance Rate
The WashU Early Decision acceptance rate was 27.0% for the Class of 2029, with 1,333 students admitted from 4,934 applications across the ED I and ED II rounds, per the Washington University in St. Louis Common Data Set 2025-2026. Applicants outside the binding rounds were admitted at 9.3%, against an 11.9% overall rate.
Yes, by one of the widest margins among top 25 privates: 27.0% in the binding rounds against 9.3% outside them, roughly 2.9x. The 1,333 binding admits can fill up to 68% of the 1,961 enrolled seats, leaving the remaining pools to compete for roughly a third of the class. Recruited athletes and institutional priorities concentrate in the early pool, so an unhooked applicant should discount the raw multiple, but the structural advantage at WashU is unusually large.
Yes, and it is new. The 2025-2026 Common Data Set reports a nonbinding Early Action plan closing November 2 with decisions on December 23, and states that the plan is not restrictive, so students may apply to other early programs simultaneously. Early Action buys a December answer without commitment; the binding Early Decision rounds remain the path that converts commitment into a materially higher admit rate.
ED I if WashU is the clear first choice and the file is complete at a competitive level by November 2, since the December 11 decision arrives with time to regroup. Early Action fits a student who wants WashU in the December mix without a binding commitment, at ordinary rather than binding round odds. ED II serves a student whose fall semester materially strengthened the record, or one released from a binding round elsewhere in December who is certain WashU is next. Both ED rounds carry the identical binding commitment; only the calendar differs.
No. The Common Data Set states that WashU has adopted a test optional policy and that all applicants receive full consideration with or without scores. Among enrolled first years, 32% submitted an SAT with a middle 50% of 1500 to 1550 and 29% submitted an ACT with a middle 50% of 33 to 35, so a score inside those bands strengthens a binding application while a score below them can be withheld.
Better than the binding label suggests. WashU meets 100% of demonstrated need, has eliminated loans from every undergraduate aid package, and excludes home equity from its need analysis; the average first year package was $81,871. The aid calendar tracks the admission calendar, with ED I aid materials due November 17 and the aid decision arriving with admission on December 11 ahead of a January 4 reply date, so a family sees its complete price before committing. The recognized release from an ED agreement remains an aid award that does not make attendance feasible.
Yield certainty drives it. Every binding admit enrolls by definition, so WashU can build most of its class from a pool one seventh the size of the regular pool, and applicant interest is a considered factor in the file review. Self selection also plays a role, since binding applicants tend to be well matched and well prepared. The raw 2.9x gap therefore overstates the edge for an unhooked applicant, but even after discounting, the binding rounds at WashU carry one of the largest structural advantages among top 25 privates.
The January 4 deadlines mean the rest of the list must be ready before the December 11 decision arrives. A deferred applicant moves into the later pool with the binding obligation released and should submit midyear grades plus a focused update. A denied applicant is done at WashU for the cycle, and the productive January move is a binding ED II application at another university, or at WashU itself for a student originally denied elsewhere, but only if those essays and materials are already drafted.
