A survey of all UK deaneries was carried out to identify the processes and procedures associated with the approval of GP clinical and educational supervisors and to document the current similarities and difference between deaneries. The results of the survey were placed in the context of recent literature. Results showed notable variation in some areas as well as relatively recent developments becoming established practice, such as the requirement for a certificate of medical education. Overall, results indicate a time of transition and the potential for practice to be aligned across deaneries and local education and training boards (LETBs).
