In the United States, most state registration boards require a degree from an accredited professional degree program as a prerequisite for licensure. The National Architectural Accrediting Board (NAAB), which is the sole agency authorized to accredit U.S. professional degree programs in architecture, recognizes three types of degrees: the Bachelor of Architecture, the Master of Architecture, and the Doctor of Architecture. A program may be granted a 6-year, 3-year, or 2-year term of accreditation, depending on the extent of its conformance with established educational standards.
Doctor of Architecture and Master of Architecture degree programs may consist of a pre-professional undergraduate degree and a professional graduate degree that, when earned sequentially, constitute an accredited professional education. However, the pre- professional degree is not, by itself, recognized as an accredited degree.
The University of Washington offers the following NAAB-accredited degree programs:
2+year Master of Architecture (pre-professional degree + 91 credits)
3+year Master of Architecture (non pre-professional degree + 145 credits)
Both programs were granted full 6-year terms of accreditation in 2008. The next accreditation visit for both programs is in 2014.
