An architect must earn a professional degree from an accredited university or college. They typically focus on curriculum in architectural history and theory, building design, computer-aided design and drafting (CADD), construction methods, math, physical sciences and other liberal arts courses. Upon completion of undergraduate or postgraduate programs, architects must complete a three-year internship before taking the Architect Registration Examination administered by the National Council of Architectural Registration Boards, or NCARB. This exam is designed to test the knowledge and skills regarding architecture to become a licensed architect. Most states require licensure and continued education to remain in compliance.
