Washington University in St. Louis SAT & ACT scores.
Washington University in St. Louis is among the most selective universities in the United States. In the latest admission cycle (for the Class of 2028), WashU received roughly 33,000 applications and offered admission to only about 4,290 students—an acceptance rate near 13%. That means just around 13 in 100 applicants earn a spot, underscoring WashU's high standards and competitive environment year after year.
About 25% of applicants submit an SAT score and 41% an ACT score.
WashU's Early Decision plan is binding. It admits a significant portion of each class (around half of enrolled students often come through ED). Applying Early Decision signals that WashU is your top choice and usually boosts admission chances. However, because ED is binding, students should only use it if WashU is absolutely their first choice.
Testing policy has evolved. WashU was test-optional in recent years, but for the 2025–26 admissions cycle (for fall 2026 entry), WashU will require SAT or ACT scores again (with hardship exceptions). In other words, applicants next year must submit test results. Even before this change, nearly all successful applicants who reported scores were at the very top of the national scale, reflecting WashU's rigorous academic profile.
SAT scores
For WashU's average SAT scores, admitted students' middle-50% composite SAT range is roughly 1490–1570. This elite band mirrors WashU's high academic expectations and means admitted students typically score near the top of the national distribution.
For section detail: the SAT Reading and Writing component (formerly called Evidence-Based Reading & Writing) for WashU's admitted students falls around 730–770 for the middle 50%. These scores reflect the critical reading, writing, and analytical skills WashU expects across all majors.
On the Math portion, WashU's middle-50% range is about 760–800. This upper-tier performance signals comfort with advanced algebra, data analysis, and precalculus—skills that WashU seeks in both STEM and quantitatively rigorous social science applicants.
If you're wondering about a WashU average SAT, aim for the mid-1500s. WashU evaluates applications holistically, so scores below 1490 don't automatically disqualify you. But in such a competitive pool, you'll need compensating strengths (like outstanding coursework, unique talents, or leadership impact) to remain viable.
Policy note: WashU superscores the SAT. They consider your highest Reading and Writing and Math section scores from all test dates. In practice, this means a weak section can be improved with a retake, boosting how your WashU SAT scores are evaluated.
ACT scores
Looking at WashU's ACT range, the middle 50% of composite scores is about 33–35. This implies most admitted students are scoring at or near the top percentile nationally. In other words, WashU ACT results cluster in the mid-30s, reflecting the school's competitive applicant pool.
By section, admitted students tend to excel in English (ACT Reading and Writing). The middle 50% for ACT English is approximately 34–36, meaning the average admitted student often scores a 34 or above on this section. These scores demonstrate the strong critical reading and communication skills WashU expects.
ACT Math scores at WashU are similarly high: the middle 50% falls around 31–35. While there's a bit more spread than English, competitive applicants still show very strong quantitative fluency. Many engineering or economics hopefuls, for example, hit scores in the mid-30s on ACT Math.
WashU superscores the ACT just as it does the SAT, taking the highest section scores across multiple test dates. The optional writing section is not required, but applicants may submit it if it strengthens their profile. Using superscoring, you can focus on improving any weaker sections in additional attempts.
If you're estimating a WashU average ACT, plan around 35. Given WashU's low admit rate, even moving from a 33 to 35 can enhance your profile. Pair high test scores with rigorous coursework, standout essays, and meaningful extracurriculars to maximize your chances.
Admission numbers
Here's the reality: WashU's admit rate is only about 13%, with roughly 33,000 applications for about 4,290 spots (around 1,800 students actually enroll). That's why understanding the WashU average SAT and WashU average ACT benchmarks matters—they align with the profile of those admitted. If your scores fall near or above WashU's 75th percentile (around a 1570 SAT or 35 ACT), you're in stronger territory.
That said, WashU emphasizes holistic review. Admissions officers weigh coursework rigor, grades, essays, recommendations, and personal qualities. In a pool full of near-perfect transcripts, however, top-tier SAT/ACT scores help confirm to WashU that you're ready for the academic rigor. In short, scores aren't everything, but they remain a key part of the competitive signal.
Strategy snapshot: If WashU is your clear first choice, applying Early Decision could improve your odds by signaling commitment. Take advantage of superscoring by retaking tests to shore up any weak section. Also balance test prep with maintaining strong senior-year classes and crafting compelling essays. Meet WashU's testing bar (target near the top of the WashU SAT and ACT ranges) and then win the admissions read with the rest of your profile.
