The International Union of Architects (UIA) is a global organization made up of national architectural associations working together toward a common goal of uniting architects across the world. The UIA is comprised of professional architecture organizations from 124 countries and territories, representing over one million architects worldwide.

While the American Institute of Architects (AIA) is the official U.S. member of the UIA, NCARB maintains an active role in the UIA’s Professional Practice Commission and helps develop and implement international standards of architectural practice. You can find the current recommended standards in the UIA Accord on Recommended International Standards of Professionalism in Architectural Practice.
