Professional requirements for architects
Professional requirements for architects vary from place to place, but usually consist of three elements: a university degree or advanced education, a period of internship or training in an office, and examination for registration with a jurisdiction. Professionals engaged in the design and supervision of construction projects prior to the late 19th century were not necessarily trained in a separate architecture program in an academic setting.
