AC Master Executive Coach: The Highest AC Individual Credential

What Is the AC Master Executive Coach?

The AC Master Executive Coach is the highest individual accreditation awarded by the Association for Coaching. It recognizes coaches who have demonstrated mastery in executive and leadership coaching at the most senior organizational levels, with extensive experience, deep supervision practice, and a significant contribution to the coaching profession.

Comparable to the ICF MCC or EMCC Master Practitioner in terms of what it signals, the AC Master Executive Coach is held by a small number of the most senior coaches in the UK coaching community.

AC Master Executive Coach Requirements

• Prerequisite credential: Typically requires AC Accredited Executive Coach or equivalent
• Extensive experience: Years of executive coaching practice at the highest organizational levels

Who Holds the AC Master Executive Coach?

This credential is held by coaches at the very top of the UK executive coaching market — those coaching boards, C-suites of FTSE companies, UK government ministers, and senior public sector leaders. It is not a credential early-career coaches should aim for; it represents decades of practice and professional contribution.
