The Graduate School of Architecture & Urban Design offers an accredited first professional degree to students with either an undergraduate degree in architectural studies, or an undergraduate degree in other disciplines. The duration of graduate studies varies according to prior preparation and course work in architecture, and the quality and complexity of work in an applicant's portfolio.

The six-semester MArch 3 program forms the overall basis for the graduate program. Students with strong backgrounds in architectural studies (a BS in Architecture, typically) are considered for selective entry into the four-semester MArch 2 program. All MArch programs at Washington University are STEM-designated.

The Graduate School reserves the right to place students at the level the Admissions Committee deems appropriate, on the basis of portfolio evaluation, transcript evaluation, and overall preparation for the intensity of the design curriculum.
