Abstract: The purpose of this paper is to shed some light on the concept of clinical supervision specifically in relation to mental health nursing. The author talks briefly about the naming and history of clinical supervision and aims to provide some clarity around defining the concept. There is discussion around the role, value and objectives of clinical supervision before critical examination of two models of clinical supervision within two different contexts. Finally the strengths and weaknesses of each model are discussed, and the differences illustrate some of the contextual factors of clinical supervision.
