The two largest coaching associations, the ICF and EMCC are both offering such designations: The Master Certified Coach for ICF and the Master Practitioner for EMCC. The author has run Coaching Masterclasses for the preparation for ICF MCC since 2018.

This book is aimed at coaches who would like to celebrate their lifetime achievement by receiving a mastery level certification. Both certifications are described in detail: the requirements, how to meet them, the process, your mindset etc. The book is intended to answer all questions about these potentially daunting certification processes.
