Admission requirements and costs at a glance
University of Colorado Boulder is a public university in Boulder, Colorado, founded in 1876. It is a very large institution with roughly 31,000 undergraduates on a college town campus, a student-faculty ratio of 18:1 and a six-year graduation rate of about 73%.
Admission is broadly accessible: the university admits most applicants who meet its published requirements, with a reported acceptance rate near 80%. Students who enrol typically present SAT scores in the 1150-1370 range or ACT results of 25-31. 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 $13,000 for residents of Colorado and $41,000 for non-residents, a difference of $28,000 per year. Residency rules are set by the state and are applied strictly; read our guide to in-state and out-of-state tuition before assuming you can qualify after moving.
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 15, with an early round on November 15 (Early Action). The application fee is $70, and fee waivers are available for applicants with documented financial need.
University of Colorado Boulder 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.
