When Is Washington University Application Due?

Washington University in St. Louis offers three application options for first-year students: Early Decision I, Early Decision II, and Regular Decision. Both Early Decision plans are binding for applicants who already know WashU is their top choice. Regular Decision is non-binding and gives students more time to complete their applications.

Before we break down each pathway in detail, here’s a quick look at the key Washington University application deadlines you should know:

Transfer and financial aid deadlines follow their own separate timelines, which we’ll cover in later sections.

WashU Early Decision Deadline

If Washington University in St. Louis is your clear first choice and you’re ready to commit, applying through Early Decision might be the right path. This option is binding, meaning that if you’re admitted, you must enroll at WashU and withdraw your applications to other schools.

Below is the Washington University application deadline and timeline for Early Decision:

What is Washington University Early Decision?

Early Decision at WashU is a binding commitment. If you’re admitted, you must enroll and withdraw all other applications. Choose ED I or ED II only if you are confident that Washington University is your top choice, your application is strong by the deadline, and you’re comfortable committing once you see your financial aid package.

While you may apply to other schools through non-binding options before receiving your ED decision, you must commit to WashU if admitted in December (ED I) or February (ED II). This makes Early Decision best for students who are sure WashU is their first choice and ready to make the commitment.

WashU Early Decision acceptance rate

For the Fall 2024 entering class, Washington University in St. Louis reported 4,817 Early Decision applications and admitted 1,217 students. This results in an Early Decision acceptance rate of about 25.3%.

This dataset confirms that the Early Decision admit rate is significantly higher than the overall acceptance rate (12.1%) for the Class of 2028. Like at most selective universities, applying ED gives you access to a smaller pool and earlier notification, but the applicant group tends to be very strong.

If Washington University is your clear first choice and your application is polished by the ED I or ED II deadlines, then applying Early Decision can be a strategic choice. Still, it’s important to remember that ED is binding, and you should be confident both academically and financially before committing.

WashU Regular Decision Deadline

If you want more time to prepare your application or prefer to compare admission offers before committing, Regular Decision is the best route for you at WashU. This option is non-binding and open to all applicants, making it the most common application pathway for WashU students.

Below is the Washington University application deadline and timeline for Regular Decision:

What is Washington University Regular Decision?

Regular Decision at WashU is the standard application plan that most students choose. Unlike Early Decision, it is non-binding, meaning you can apply to multiple colleges and compare admissions offers before making your choice. This flexibility is especially helpful if you want extra time to polish your essays, improve grades, or take standardized tests later in the year.

The admissions team reviews applications holistically, evaluating academic achievements, extracurricular involvement, personal qualities, and the context of your background.

Applicants will receive one of three outcomes in late March: admission, denial, or placement on the waitlist. If admitted, you’ll need to confirm your enrollment by May 1. If waitlisted, you may still have the chance to be admitted after May 1 if space becomes available in the class.

WashU Regular Decision acceptance rate

Washington University in St. Louis does not release a separate breakdown of Regular Decision statistics. However, we can estimate the Regular Decision acceptance rate using the data available for the Fall 2024 entering class:

• Total applicants (overall): 32,754
• Total admits (overall): 3,951
• Early Decision applicants: 4,817
• Early Decision admits: 1,217

From this, we can estimate the Regular Decision pool:

• RD applicants = 32,754 – 4,817 = 27,937
• RD admits = 3,951 – 1,217 = 2,734

Therefore, the estimated Regular Decision acceptance rate is approximately 9.8%

This means that while WashU’s overall admit rate was about 12.1%, the Regular Decision acceptance rate is noticeably lower at around 9.8%. The difference reflects the fact that a significant portion of the incoming class is admitted through Early Decision, making the RD pool more competitive.

For students applying RD, this means you’ll be competing for fewer remaining spots. WashU evaluates applicants holistically, considering not only academics but also extracurricular involvement, personal qualities, and the context of your background. With a large number of strong applicants, standing out requires careful preparation and a strong application.

How to Apply to WashU

Once you know the Washington University application deadline, the next step is making sure you understand exactly what WashU expects from applicants. Preparing early will give you enough time to gather materials, write essays, and review everything before submission. Being organized is the best way to avoid last-minute stress and ensure a strong application.

Washington University admission requirements

Here is what you need to submit to apply to Washington University:

• Application platform. WashU accepts the Common Application or the Coalition Application (via Scoir). You only need to choose one of these platforms when applying by the Washington University application deadline.
• Washington University writing prompts. In addition to the personal essay, WashU requires several short-answer questions and essays. These prompts allow you to highlight your academic interests, personal goals, and why you believe Washington University is the right fit.
• Official high school transcript. Applicants must submit a transcript that includes all completed coursework from grades 9 through 12. A Mid-Year Report will also be required after your first semester of senior year to reflect updated grades.
• School report and counselor recommendation. Your counselor will submit a school report that includes important context about your school, along with a recommendation letter.
• One teacher recommendation. WashU requires one letter of recommendation from a teacher in a core academic subject such as English, math, science, history, or a foreign language. If you are applying to the McKelvey School of Engineering, the recommendation should come from a math or science teacher.
• Standardized testing. Washington University is test-optional. You may choose to submit SAT or ACT scores if you feel they strengthen your application. International applicants whose primary language of instruction is not English may need to submit TOEFL, IELTS, or Duolingo English Test scores.
• Mid-Year Report. Submit this after your first semester senior year once grades are available.
• Final Report. If admitted and enrolling, you will need to submit a final transcript after graduation.
• Application fee. The fee is $75, but fee waivers are available for applicants with financial need.
• Optional supplements. Students with outstanding achievements in areas like music, art, or research may submit an optional supplement. Only include these if they add meaningful depth to your application.

While strong grades and test scores (if submitted) matter, they are only one piece of the puzzle. The admissions team also carefully evaluates essays, recommendations, extracurricular involvement, and personal qualities. Because the Washington University application deadline is highly competitive, you’ll want to present the strongest application possible to stand out.

WashU application process

Applying to WashU requires careful planning and attention to the Washington University application deadline. Below is a step-by-step guide to help you stay organized and make sure that every part of your application is submitted on time.

1. Choose your application platform.

Washington University accepts the Common Application or the Coalition Application (Scoir). You only need to submit one of these platforms when applying by the Washington University application deadline. Many students use the Common App because of its popularity, but you should choose the platform that you’re most comfortable with.

2. Write your essays.

Washington University requires a personal essay as well as several school-specific short-answer prompts. These essays give the admissions team insight into your academic interests, values, and personal goals.

Quick tips for Washington University essays:

• Begin drafting your essays well before the Washington University application deadline, ideally during the summer before senior year.
• Write authentically in your own voice so the admissions committee understands who you are.
• Avoid overly generic topics and highlight meaningful personal experiences.
• Ask trusted mentors or teachers for feedback, but make sure the final draft reflects your true self.

3. Request recommendations.

You will need one teacher recommendation from a core subject such as English, math, science, history, or a foreign language, plus a counselor recommendation. If you’re applying to the McKelvey School of Engineering, the letter should come from a math or science teacher.

Ask your recommenders at least one month before the Washington University application deadline. Provide them with a brag sheet or list of activities so they can write detailed and personalized letters.

4. Submit your application on time.

The Washington University application deadline for Early Decision I is November 1, Early Decision II is January 3, and Regular Decision is also January 3. Submitting a few days early is recommended to avoid any last-minute technical issues. Double-check that all components—including essays, transcripts, and recommendations—are included before you hit submit.

5. Track your application portal.

After submitting, you will receive instructions on how to access your applicant portal. This portal allows you to confirm that all application materials have been received and to upload any missing documents. Be sure to check regularly so you can resolve issues quickly.

6. Wait for your decision.

Washington University releases Early Decision I results in mid-December, Early Decision II results in mid-February, and Regular Decision notifications in late March.

Possible outcomes include:

• Admit. Congratulations, you’ve been accepted to Washington University.
• Defer. If you applied Early Decision, your application may be moved to the Regular Decision pool for further review.
• Deny. Unfortunately, you were not admitted and cannot reapply in that cycle.
• Waitlist (RD only). You may be offered a spot on the waitlist and could receive a final decision after May 1 if space becomes available.

While waiting, focus on keeping your grades strong and continuing extracurricular commitments. If you are deferred, you may send updates in the spring to show new progress or achievements that could strengthen your application before the Washington University application deadline review cycle closes.

WashU Transfer Deadline

The Washington University application deadline for transfers is March 2 for fall entry and October 15 for spring entry. WashU accepts transfer students for both the fall and spring semesters, but the majority of students apply for fall admission. Here is a simple timeline of key dates for transfer applicants:

Transferring to Washington University is highly competitive. For the Fall 2024 transfer cycle, 1,706 students applied to transfer. Of those, 239 were admitted, resulting in an overall transfer acceptance rate of about 14%. Out of the admitted group, 99 students enrolled at WashU.

To be considered for transfer admission to Washington University, you must:

• Have completed at least one year of full-time college coursework by the time you enroll.
• Have no more than two years of full-time study completed before your intended start date.
• Be enrolled in a degree-granting program at another accredited institution.
• Not already hold a bachelor’s degree or its equivalent.

WashU requires several important documents from transfer applicants, including:

• Official transcripts from all colleges or universities you’ve attended.
• High school transcript verifying graduation or equivalent.
• Two professor recommendations from instructors who taught you in college-level courses.
• College Report completed by a dean, registrar, or school official verifying your academic and disciplinary standing.
• Standardized test scores (optional) if you think they add strength to your application.
• Application fee of $75, or a fee waiver if you qualify.
• Optional materials, such as an art portfolio or research supplement, if directly relevant to your academic goals.

Washington University expects transfer students to bring a strong academic record, evidence of leadership or extracurricular engagement, and clear reasons for transferring. Because space is so limited, small details like recommendation quality, essays, and timeliness of your application can make a big difference.

Washington University Financial Aid Deadline

Washington University’s financial aid is fully need-based—meaning the amount you receive depends entirely on your family’s financial situation, not on grades, test scores, or extracurriculars. WashU does not offer merit-based scholarships that replace need-based aid.

Missing a financial aid deadline won’t affect your admission decision, but it can delay or reduce your aid package. Staying on top of the Washington University application deadline for financial aid is just as crucial as meeting your application deadline.

Below is the breakdown of Washington University’s financial aid timeline for the 2025–2026 admissions cycle:

U.S. and international students are both eligible to apply for financial aid at WashU. Meeting every Washington University application deadline for financial aid is essential to make sure your award is processed on time.

WashU’s aid program is completely need-based and does not include loans. Most students from families with an annual income below $100,000 are not expected to pay tuition or fees. Even if you are uncertain about your eligibility, it is strongly recommended that you submit the required forms by the correct Washington University application deadline. There is no penalty for applying, and many students are surprised at how much support they receive.
