WashU Supplemental Essays 2025-26 Prompts and Tips

August 27, 2025

For the Class of 2028, the WashU acceptance rate remained low at just 12%. As Washington University in St. Louis continues marching toward the single-digit admit rate club, it’s critical that prospective applicants realize the need to make a uniquely compelling case for admission, even if they already possess elite academic credentials. After all, the average SAT for an incoming freshman is well above a 1500, and 86% placed in the top 10% of their high school class–incredibly, such credentials are necessary but not sufficient in this hypercompetitive environment. This brings us to the topic of the moment – the WashU supplemental essays.

2025-2026 WashU Supplemental Essays

1) Please tell us what you are interested in studying at college and why. (250 words)

Undecided about your academic interest(s)? Don’t worry—tell us what excites you about the academic division you selected. Remember that all of our first-year students enter officially “undeclared” and work closely with their team of academic advisors to discover their academic passions. You can explore all of our majors and programs on our website.

Washington University in St. Louis wants to know about the academic discipline(s) in which you are most interested (or current leanings, if you’re undecided). They also want to know why you desire to pursue your studies at their institution. Answering both components of this question in less than 200 words is no easy task. This one is going to require a fair amount of school-specific research and a good deal of editing in order to tighten up your essay enough to stay under the word count.

For a deeper dive, let’s examine the questions you’ll want to consider in your quest to writing a winning WashU “Why Us?” essay:

How did your interest in your major of choice begin and how has it matured over the years?
While pursuing your majors(s)/interest(s) of choice, how will you take advantage of the university’s immense resources both inside and outside of the classroom? Be sure to cite specific academic programs, professors, research opportunities, centers & institutes, and study abroad programs. Discuss why they pique your interest.
Are there specific student-run organizations related to your field of study that you would like to join?

As you enter the prewriting stage, you’ll want to avoid some common pitfalls that we observe applicants fall into when attacking the WashU “Why Us?” essay. We don’t want to label these as “mistakes” (there is nothing inherently wrong with them); they just don’t add any needle-moving value, which is the only goal here!

Common components of a generic “Why WashU?” essay:

According to US News, Washington University in St. Louis is a top-15 school.
Too much attention to the prestige/reputation of the Olin School of Business or McKelvey School of Engineering.
Recycled statements from your other “Why Us?” essays that come across as stale, impersonal, or worst of all–irrelevant/inaccurate.
An itinerary of all the things you plan to do in St. Louis.
Statements about how WUSTL feels like home, you know it’s the right place for you, or you’ve wanted to attend since kindergarten. Show your excitement about the school through well-researched specifics instead.

Big-picture thoughts on the “Why Us” essay:

In any “Why Us?” composition, you need to show that you’ve done your homework on a given school, but you don’t want it to read like a rote list of items that you Googled an hour prior to writing the essay (even if the timing of the Google search is roughly accurate).

In addition to the pure research element, a lot of the time and skill required in creating a stellar WashU essay will involve connecting the classes, professors, opportunities, etc. of interest that you have uncovered to your distinct values, talents, aims, proficiencies, and future goals.

2) This optional question allows you to add another dimension to your application – something that the admissions committee might not learn by reading your transcript or your personal statement. If you plan to apply for one of the Signature Scholar Programs, we highly recommend you complete this supplement.

WashU is a place that values diversity of perspectives. We believe those perspectives come from a variety of experiences and identities. Respond to one of the following prompts to help us understand “Who are you?”: (250 words)

WashU supports engagement in the St. Louis community by considering the university as “In St. Louis, For St. Louis.” What is a community you are a part of and your place or impact within it?
WashU strives to know every undergraduate student “By Name & Story.” How have your life experiences shaped your story?

While this essay is technically “optional,” we advise every single applicant to WashU to opt in. Remember, WashU is one of those rare schools that rejects students with near-perfect (or even perfect) academic credentials. It is essential that you showcase the characteristics and skills that make you one-of-a-kind.

Keep scrolling for a breakdown of each prompt:

1) WashU supports engagement in the St. Louis community by considering the university as “In St. Louis, For St. Louis.” What is a community you are a part of and your place or impact within it?

“Community” can be defined in myriad ways: it could be large-scale, like an ethnic, religious, or neighborhood community, or small-scale, like a group of individuals who gather for a club, sport, or service project.

Most applicants to WashU are involved in at least one “community.” You may be the captain of a team, the editor-in-chief of your school paper, a member of your town’s trail clean-up team… but don’t just rest on those laurels—instead, bring your involvement to life. Use your writing ability to show what type of community member you are rather than merely telling. What is your role within your chosen community? Within that role, how do you lead, guide, or interact with others? What have you learned and how have you grown? Strive for personal detail here rather than re-hashing your resume.

Finally, draw on past evidence of your commitment to being a positive force in your community and speculate how that is likely to manifest on WashU’s campus. It’s a great idea to research and cite WashU student-run organizations and/or local nonprofit groups.

2) WashU strives to know every undergraduate student “By Name & Story.” How have your life experiences shaped your story?

Take note of the wide-open nature of this prompt. “Life experiences” could mean anything: your upbringing, your cultural background, your family, an aspect of your personal identity, your involvement in a particular activity or community, a challenge you’ve faced, a moment that changed your perspective…the list goes on.

Although this prompt’s open floor plan may feel daunting, a good tactic is to first consider what has already been communicated within your Common App personal statement, activities list, and “Why Us?” WashU essay. What important aspects of yourself have not been shared (or sufficiently discussed)? The admissions officer reading your essay is hoping to connect with you through your written words, so—within your essay’s reflection—be open, humble, thoughtful, inquisitive, emotionally honest, mature, and/or insightful about what you learned and how the experience you chose has impacted your life. No matter what type of story you tell, the goal is to have the reader come away saying, “I can definitely see this applicant as a contributing member of our talented and engaged student community.”

How important are the WashU supplemental essays?

WashU designated 8 factors as “very important” to their applicant evaluation process. These are: essays, recommendations, talent/ability, character/personal qualities, GPA, test scores, class rank, and the rigor of one’s curriculum. Clearly, the essays are among the most important factors in this holistic process.
