The accreditation of medical school programmes and the licensing and revalidation (or recertification) of doctors are thought to be important for ensuring the quality of health care. Whereas regulation of the medical profession is mandated in most jurisdictions around the world, the processes by which doctors become licensed, and maintain their licences, are quite varied. With respect to educational programmes, there has been a recent push to expand accreditation activities. Here too, the quality standards on which medical schools are judged can vary from one region to another.
