Admission requirements and costs at a glance
Washington University in St. Louis is a private nonprofit university in St. Louis, Missouri, founded in 1853. It is a mid-sized institution with roughly 8,000 undergraduates on a suburban campus, a student-faculty ratio of 7:1 and a six-year graduation rate of about 94%.
Admission is highly selective: the university admits roughly one applicant in four or fewer, with a reported acceptance rate near 12%. Students who enrol typically present SAT scores in the 1500-1570 range or ACT results of 33-35. Those ranges describe the middle half of enrolled students, which means a quarter of them scored below the lower figure — a score outside the range does not by itself decide an application.
Published tuition is about $64,000 per year and applies to every student regardless of the state they live in, which is the normal pattern at private universities. The figure excludes housing, food, books and fees, and institutional aid frequently reduces it substantially — run the university's net price calculator before treating it as the price you would pay.
Test policy: Test-optional. Submit scores only if they sit at or above the enrolled range shown above; otherwise apply without them and let the transcript carry the file. Note that merit scholarships and honours colleges sometimes keep a score requirement the admission office has dropped.
The regular application deadline is January 2, with an early round on November 1 (Early Decision I, binding). The application fee is $75, and fee waivers are available for applicants with documented financial need.
Washington University in St. Louis is institutionally accredited by HLC, which is what makes its credits transferable and its students eligible for federal financial aid. Our guide to accreditation in the United States explains how to verify this independently and why programme-level accreditation matters separately for licensed fields.
