This practical guide argues that both mentor coaching and supervision be mandated by the professional coaching bodies as part of coaches' continuous professional development. Mentor coaching is not just for those coaches seeking a credential: it is for lifelong professional development for every coach, at every level of the profession.You are the best coaching tool there is. Tools need to be oiled, sharpened, repaired and protected to keep them in tip top condition. That's what mentor coaching and supervision do - they keep coaches sharp and fit for purpose.The reader will learn how to develop as a coach using mentor coaching, as well as how to develop as a mentor coach, to support other coaches to develop. Clare Norman explains what mentor coaching is, why it is so important and the competencies for mentor coaching.How coaches show up in the room is more important than how much we know about the theory behind coaching. Clare Norman's concise book is important reading for all practising coaches, as well as coaches and mentor coaches in training.
