It is common for professional qualification in the UK to require professional experience in addition to academic qualification. For Architecture, the standard route has a year of experience between the bachelor's and master's stages and a further year after the master's before the final examination; becoming a Chartered Engineer requires post-degree Initial Professional Development that typically takes four to six years; becoming a General Practitioner requires five years of study beyond the MBBS, while qualifying as a Consultant takes seven to nine more years.
