M ARCH The Master of Architecture (M.Arch.) is a professional degree in architecture, qualifying the graduate to move through the various stages of professional accreditation (internship, exams) that result in receiving a license.The degree is earned through several possible paths of study, depending on both a particular program's construction, and the candidate's previous academic experience and degrees. M.Arch. degrees vary in kind, so they are frequently given names such as "M.Arch. I" and "M.Arch. II" to distinguish them. All M.Arch. degrees are professional degrees in architecture. There are, however, other master's degrees offered by architecture schools that are not accredited in any way.
