What is coach supervision?

Coach supervision is NOT coaching the coach!

Coach supervision is:

  • reflective practice for learning and development. In partnership with me as a coach supervisor, you as a coach will examine the coaching work within evolving systems, focusing on patterns, thinking models, and relationship dynamics.
  • the formal process of professional supervision support ensures continuing development of you as a coach and the effectiveness of your coaching work, through interactive reflection, interpretative evaluation, and the sharing of expertise in our supervisory sessions. (I as your supervisor have no direct contact with your client)
  • the process by which you as the coach, and with my support in the role of your coach supervisor, can attend to understanding both the client-system and yourself as part of the client-coach system, and transform your work.

Coach supervision  benefits the coach, the clients of the coach, and their organizations and serves as a cornerstone for the integrity and quality of coaching through:

  • Coaching skill-building and increased awareness and understanding of how the coach reacts to the dynamics of client interventions
  • Support for the emotional well-being of the coach the working with  clients and the client-system affected by the changes of COVID and the VUCA environment
  • Attention to sustaining a professional caliber of services offered by the coach, including adherence to the Global Code of Ethics.
