The National Architectural Accrediting Board provides the following statement:

“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 US professional degree programs in architecture, recognizes two types of degrees; the Bachelor of Architecture and the Master of Architecture. A program may be granted a five-year, three-year, or two-year term of accreditation, depending on its degree of conformance with established educational standards.

“Masters degree programs may consist of a pre-professional undergraduate degree and a professional graduate degree, which, when earned sequentially, comprise an accredited professional education.  However, the pre-professional degree is not, by itself, recognized as an accredited degree.”
