External quality assurance for teaching and learning is a long-standing feature of medical education and is associated with registration as a professional. In many instances, these quality assurance processes result in formal accreditation of programmes. This chapter investigates quality assurance practices in three countries, two of which are formal accreditation processes, building on the survey of accreditation world-wide completed by van Zanten et al. (2008). The chapter explores the extent to which standards detail teaching methods. It also examines the standards for accreditation itself and the extent to which different agencies meet them.
