Membership of the Royal Colleges of Surgeons (MRCS) is a postgraduate diploma for surgeons in the UK and Ireland. Obtaining this qualification allows a doctor to become a member of one of the four surgical colleges in the UK and Ireland, namely the Royal College of Surgeons of Edinburgh, the Royal College of Surgeons of England, the Royal College of Physicians and Surgeons of Glasgow and the Royal College of Surgeons in Ireland. The examination, currently organised on an intercollegiate basis, is required to enter higher surgical training (ST 3+) in one of the Royal colleges.[1] Thus today's MRCS has replaced the former MRCS(Eng), MRCS(Ed), MRCS(Glas), and MRCS(I). (Similarly, the MRCP is also now intercollegiate.)
