What Is WashU’s Waitlist Acceptance Rate?
WashU’s waitlist is defined by its inconsistency. The university admitted zero students from the waitlist in four recent cycles (Classes of 2026, 2019, 2017, and 2015). In years when the waitlist is used, WashU can admit up to several hundred students. The 61% ED fill rate structurally limits waitlist availability: with most of the class locked in through binding early rounds, fewer RD spots exist, and therefore fewer spots can open through the waitlist. For WashU acceptance rate data, see our analysis. For how this compares, see our waitlist rates comparison and Ivy League waitlist comparison.
| Class | Waitlisted | Admitted | Notable |
|---|---|---|---|
| Class of 2028 | ~3,000 | ~100 | Moderately active |
| Class of 2027 | ~2,500 | ~150 | Active year |
| Class of 2026 | ~2,000 | 0 | Zero admits |
| Class of 2025 | ~2,000 | ~200 | Active (COVID yield) |
| Class of 2019 | ~1,800 | 0 | Zero admits |

Why Does WashU Skip the Waitlist Some Years?
WashU’s 61% ED fill rate gives it strong yield predictability. When ED yield is high and RD yield meets expectations, the class fills without needing the waitlist. The four zero-admit years all coincided with strong yield cycles. As WashU’s ED percentage continues to climb, zero-admit years may become more common.
When Does WashU Notify Waitlisted Students?
WashU typically releases waitlist decisions between mid-May and late June, after the May 1 deposit deadline. In years when WashU does not use its waitlist, students may not receive formal notification until summer. Commit to your best alternative by May 1.
How to Write a WashU LOCI That Works
WashU values intellectual curiosity, cross-disciplinary exploration, and community engagement. Your LOCI should reference specific programs (Olin Business School, the Brown School for social work, the interdisciplinary “Boundless” curriculum), campus culture, or research opportunities. Include one meaningful update. State clearly that WashU is your first choice. For a template, see our LOCI guide. For essay strategy, see our Common App essay guide. For broader waitlist strategy, see our complete waitlist guide.
How Does WashU’s Waitlist Compare to Peer Schools?
| School | WL Pattern | Zero-Admit Years? |
|---|---|---|
| WashU | 0 to ~200 | Yes (4 recent years) |
| Vanderbilt | 5-10% | No |
| Rice | 0 to 150+ | Yes (1 year) |
| Notre Dame | 0-48% | Yes (4 years) |
| Tufts | 35.72% | No (uses it 7/10 years) |

Final Thoughts: Your WashU Waitlist Action Plan
Accept your waitlist spot. Write a cross-disciplinary LOCI referencing WashU’s unique programs. Commit to your alternative by May 1. Be realistic: WashU has admitted zero students from the waitlist in 4 recent years. But when it does move, it can move significantly.

Frequently Asked Questions
WashU’s waitlist is among the least active in the top 20. With 61% of the class filled through ED, WashU’s yield prediction is exceptionally accurate, leaving little reason to turn to the waitlist. In four recent cycles, WashU admitted zero students from the waitlist. The practical advice: stay on the list if WashU was your top choice (it costs nothing), but plan and commit fully to your best alternative. Do not allow the WashU waitlist to prevent your child from engaging with the school they will actually attend.
In many cases, yes. WashU’s RD acceptance rate (approximately 5-7%) is dramatically lower than its ED rate. A student who would have been admitted through ED may be waitlisted in the RD round simply because fewer spots remain. This is not a reflection of your child’s qualifications – it is a structural consequence of WashU’s ED-heavy admissions model. For families with younger children or future applicants, WashU is the strongest case study for why ED matters at schools that fill the majority of their class through binding early commitment.
Write one, but keep expectations realistic. A brief, specific LOCI (under 300 words) that states WashU is your first choice, provides one meaningful update, and references a specific WashU program does not hurt and positions you if the rare waitlist offer occurs. However, do not invest significant emotional energy drafting multiple versions or sending follow-up materials. One concise letter is sufficient. If WashU admits from the waitlist (which is increasingly rare), they will draw from students who have confirmed continued interest.
Yes. Emory (11% acceptance rate) and Tufts (10%) are peer institutions with comparable academic quality and career outcomes. For pre-med, Emory may actually be stronger than WashU for undergraduate clinical access due to Emory Hospital proximity (versus WashU’s medical campus being separate from the undergraduate campus). For business, WashU’s Olin School is stronger than either Emory’s Goizueta or Tufts. For liberal arts broadly, all three are excellent. Committing to Emory or Tufts is not settling – it is enrolling at a school that would have been considered exceptional by any measure a decade ago.
In the rare years when WashU uses its waitlist, activity occurs between mid-May and late June, concentrated in the first two weeks after May 1. Given the zero-admit trend, any movement is a positive surprise rather than an expected outcome. WashU does not rank its waitlist, so all waitlisted students are reconsidered holistically if spots open. If you have not heard by June 15 in a typical year, the waitlist has not moved and your chances are zero.
The zero-admit pattern reflects WashU’s successful yield prediction rather than manipulation. With 61% of the class locked in through ED, WashU accurately projects how many RD admits will enroll. The waitlist exists as a genuine safeguard in case yield comes in lower than expected, but WashU’s ED-heavy model produces consistent yield, making the safeguard unnecessary in most years. It is not a marketing tool – it is an unused backup plan at a school that has perfected its enrollment management through binding early commitments.
WashU is need-aware, which means ability to pay can factor into admissions and potentially waitlist decisions. Being full-pay removes one friction point: your enrollment does not draw from WashU’s financial aid budget. In theory, this could provide a modest advantage if the waitlist activates. In practice, WashU’s waitlist has admitted zero students in four recent years regardless of financial status, so the full-pay advantage is theoretical rather than practical. The need-aware benefit is most impactful during the initial admissions review (another reason ED is critical), not during a waitlist process that rarely moves.
The three schools target different student profiles. WashU (St. Louis) is strongest for pre-med (Barnes-Jewish Hospital, top-5 medical school), architecture, and social work. Vanderbilt (Nashville) has the strongest campus social life, Greek system, and Southern culture with growing tech and healthcare industries. Emory (Atlanta) offers the CDC and Fortune 500 proximity, plus the unique Oxford College backdoor. For ED strategy: WashU’s 61% ED fill gives it the largest ED advantage. Vanderbilt and Emory both fill approximately 50% through ED with comparable rate gaps. Apply ED to the school whose specific academic strengths and campus culture best match your child. All three reward authentic demonstrated interest and punish generic applications.
