The International Coach Federation, ICF, provides a listing and explanation of their 11 Core Competencies of a Coach at https://www.coachfederation.org/corecompetencies and information on how they are evaluated. Visit www.CoachFederation.org and look for their updated information (changing at the time of this publication).
The yearly book series put out by the Center for Coaching Certification, Coaching Perspectives III chapter titled About Coaching explains the use of the 11 Core Competencies of a coach in coaching relationships. The chapter on Coaching to Increase Sales in the same book applies the competencies in a sales environment.
The gold standard in coaching is the ICF. The ICF has standards for approving coach training and the requirement of 60 hours of coach training to become a member. To earn a coaching credential with the ICF requires training, experience coaching, mentor coaching, taking their exam, plus a recording of a coaching session. Given this information about coaching as a profession, it makes sense that models and processes be built on or work with the 11 Core Competencies of a coach from the ICF.
Approaching the 11 Core Competencies of a Coach as both a model and process in coaching is smart.
This blog series provides a plan for a coach to develop and apply the 11 Core Competencies of a Coach in their model and process.
