To become an architect in the United Kingdom, you must first complete a degree in architecture that is recognized by the Architects Registration Board (ARB). After completing a degree in architecture, the next step is to gain practical experience through a period of work-based learning known as the Part 3 qualification. Once you have completed your degree and the Part 3 qualification, you are eligible to apply for registration with the ARB. To register, you must pass an assessment of your professional competence, which includes a written examination and an interview.
