A groundbreaking resource for this burgeoning profession, this text presents several different coaching approaches along with the empirical and theoretical knowledge base supporting each. Recognizing the special character of coaching-that the coaching process is non-medical, collaborative, and highly contextual-the authors lay out an evidence-based coaching model that allows practitioners to integrate their own expertise and the needs of their individual clients with the best current knowledge. This gives coaches the ability to better understand and optimize their own coaching interventions, while not having to conform to a single, rigidly defined practice standard.
