Professional Practice is a RIBA Part 3 course and examination that allows successful candidates to register as architects with the Architects Registration Board (ARB). The course is open to AA RIBA Part 2 graduates and eligible non-graduates. It is also available to registered professionals who may wish to refresh their knowledge of architectural practice through Continuous Professional Development. The course is offered in two formats: in autumn as a full-time two-week course and in spring as a part-time ten-week course taking place on Saturdays, beginning in January.
