Becoming a general practice supervisor: A longitudinal multi-case study exploring key supportive factors.

Becoming a general practice supervisor is situated in the context of a workplace delivering clinical services, a training programme and personal life circumstances. It can be challenging and rewarding. Insufficient support may result in unintended attrition. Learning in this role is facilitated by enabling the new supervisor to find meaning in the role; structured allocation of time to engage effectively; a positive trainee-supervisor relationship; administrative support by practices; information, advice and remuneration from the training programme; and interactions with new and experienced supervisor peers.
