Washington University in St. Louis asks for one required supplemental essay of 250 words: what you are interested in studying at college and why. The prompt never says WashU, and WashU reads it as its “Why WashU” essay anyway. It says so on its own “What We’re Looking For” page. Beyond Boundaries applicants and Signature Scholar applicants answer one more 250 word question each, and there is an optional 90 second video. For each prompt below, we offer expert guidance on what the question is really testing and how to answer it.
What is WashU’s acceptance rate?
WashU’s overall acceptance rate was 12.2% for the Class of 2030. It has not released acceptance rates by application round for that class.
- Overall: 12.2%
- ED: Not Reported
- EA: Not Reported
- RD: Not Reported
- SAT 25th percentile: 1500
- SAT 50th percentile: 1530
- SAT 75th percentile: 1550
What SAT score do you need for WashU?
WashU is test optional and lists scores among the things it calls truly optional, with no penalty for leaving them out. If you submit, the middle 50 percent of enrolled students scored 1500 to 1550. A score in that range gets your essay read. It does not get you in. More applicants have perfect scores than WashU has places, and WashU says it considers demonstrated interest as a small part of its review. The one essay is where that interest shows up in writing.
When are WashU’s application deadlines?
Early Action and Early Decision I: November 2nd. Early Decision II and Regular Decision: January 4th. Signature Scholar priority deadline: [SCHOLAR DEADLINE]. Early Action is not binding. Both Early Decision rounds are binding. You must select one of WashU’s five undergraduate schools when you apply: Architecture, Art, Arts and Sciences, Business or Engineering. You do not declare a major until your second year, but your essay should make sense next to the school you pick.
Does WashU have a “Why WashU” essay in 2026/27?
Yes, in disguise. The prompt asks what you want to study at college and why. WashU’s “What We’re Looking For” page says, under fit and engagement, that this is its one required essay specific to WashU, and that it hopes you will learn what makes a WashU experience great and reflect that in the why you share. So one 250 word answer does two jobs most schools split: the academic pull and WashU’s place in it. Guidance is below.
WashU supplemental essay prompts 2026/27 and how to answer them
Prompts are quoted from WashU’s first year applicants page and its program pages, linked at the bottom. The 250 word essay is required of every applicant. The Beyond Boundaries question is required only if you indicate interest in that program. The Signature Scholar questions appear in the WashU Pathway after you apply and are not published.
1. What you want to study at college and why (250 words, required)
The prompt. Please tell us what you are interested in studying at college and why.
What WashU is testing. Two things in one answer: whether your academic interest is real, and whether you have looked at how WashU would let you pursue it. Read alone, the prompt is a why major question. Read with WashU’s own explanation, it is also the “Why WashU.” The reader checks the answer against the undergraduate school you selected.
How to answer. Spend about half the words on the question you want to work on and where it came from: something you did, measured, built or argued about that left you with a better question. Spend the other half on how you would pursue it at WashU: name the school you chose and one or two concrete things inside it, a course sequence, a research setting, a cross school combination WashU makes possible, or St. Louis as a place to do the work. If you are undecided, name the two or three questions pulling at you and say why WashU’s structure lets you test them. That is an answer. “I do not know yet” is not.
Avoid. A generic why major that could go to any university, which meets the prompt and misses WashU’s reason for asking it. The opposite: 200 words of WashU programs with no reason you want them. An interest that does not fit the school you selected, with no explanation of the cross school plan. And reusing your Common App essay’s central story as the why. WashU already has that essay.
2. Beyond Boundaries, only if you indicate interest (250 words)
The prompt. The Beyond Boundaries Program equips students with a set of tools to critically understand and make a difference in a complicated world where challenges require varied perspectives and skill sets. What is the big societal issue you would like to tackle? Who would you need on your team? How would the Beyond Boundaries Program support you to work with collaborative teams to address this issue?
What WashU is testing. Whether you can think about a problem as a team effort. Three questions in 250 words: the issue, who you would need, and how the program would support the team. Most drafts answer the first well and skip the other two. “Who would you need” is another way of asking what you cannot do alone.
How to answer. Pick an issue narrow enough to picture. Then name the disciplines you would need by role, the public health student, the economist, the person who knows the tenants, and say what you bring and what you do not. End with how the program’s collaborative structure fits that team.
Avoid. Climate change as the issue. Casting yourself as the lone solver with a team of assistants. And skipping the program question.
Signature Scholar Programs
Applicants to the Rodriguez, Ervin and Danforth Scholars programs answer one 250 word question per program inside the WashU Pathway after applying. WashU posts the questions on each program’s page. Applicants submit a response of up to 250 words for each program they apply to through the WashU Pathway. Rodriguez recognizes community service and celebrating cultural differences, Ervin rests on academic excellence, leadership, community service and diversity, and Danforth honors a passion for helping others. Read your question with that description in mind. Submit your admission application by December 16, 2026, for priority consideration. Complete the Scholar application in Pathway by January 4, 2027.
The optional video
WashU invites a 90 second video telling it about something important to you and says, in its own emphasis, that it is optional and that applicants will not be penalized for skipping it. If you record one, show something not already in the application. Deadlines fall about a week after each application date.
Before you write: map the whole application
Your personal statement, activities list and the one WashU essay are read as one file. With a single supplement doing two jobs, it has to add something the personal statement does not. If your Common App essay already tells the origin story of your interest, give the WashU essay a different reason or a different angle. Think of the reader as someone who has already read everything else in your file before they reach the WashU question, and who is checking it against the school you selected.
Write down what the reader already knows about you from the Common App. Then give the WashU essay the one thing that list is missing, and make at least a third of it about WashU.
WashU publishes an AI policy that lists using AI to brainstorm, draft or write essays as unethical and treats grammar review of a completed essay as a sometimes use. Read it on the What We’re Looking For page before you use any tool.
Want help connecting the pieces? Dakota, in College CoPilot’s Application Coach, uses what you have already shared to spot repetition and ask the question you have not answered. The writing stays yours.
