This publication aims to be a user-friendly resource for supervisors to develop their practice grounded in current theory and evidence. The publication extends beyond past notions of student supervision to include supervision of professionals in their work place and the emergent importance of professional mentoring for ongoing professional development. The publication is written from the perspective of a broad range of health science practitioners, including audiology, dietetics, nursing, occupational therapy, pharmacy, physiotherapy, podiatry, prosthetics and orthotics, radiography, and speech-language pathology. Acknowledging that health science professionals work in busy and often stressful environments, there is a deliberate intention to present complex theoretical material in a simple and person-centred format. Such a presentation aims to assist the reader to more easily integrate the material into their practice. The user-friendly style as previously utilized in Best and Rose (1996) continues to receive extremely positive feedback from readers and course developers. Written by multidisciplinary experts with academic and research backgrounds who also possess extensive practical experience in a variety of professional health fields. Reader-friendly, engaging material is grounded in current theory and evidence. Three distinct but interrelated fields - clinical education, professional supervision, and mentoring - are addressed together in one book for the first time. Supervision of professionals in their workplace is covered, as well as professional mentoring for ongoing professional development. Presents complex theoretical material in an engaging, "person-centered" approach. Acknowledges the importance of psychological well-being with chapters on the self in supervision and finding meaning and preventing burnout.
