Modernising Medical Careers (MMC) is a programme for postgraduate medical training introduced in the United Kingdom in 2005. The programme replaced the traditional grades of medical career before the level of Consultant. The different stages of the programme contribute towards a "Certificate of Completion of Training" (CCT). It has been dogged by criticism within and outside the medical profession, and an independent review of MMC led by Professor Sir John Tooke criticised many aspects of it.
MMC refers to both the programme itself, and also to the temporary organization, formed in 2003, responsible for its nationwide implementation.
