Not all coaches are the same. The difference is measurable.
The International Coaching Federation is the gold standard for coach accreditation. ICF credentials are the most rigorous, independently verified benchmark of coaching competency in the world.
The International Coaching Federation is the largest global organisation dedicated to advancing the coaching profession. With over 50,000 members across more than 160 countries, the ICF sets the standard for coach training, ethics, and credentialing.
A landmark 2012 study by PricewaterhouseCoopers, commissioned by the ICF, found that 86% of organisations that used coaching reported a positive return on investment, and that credentialled coaches consistently outperformed their non-credentialled peers on client satisfaction and measurable outcomes.
- 60+ hours training
- 100+ client hours
- Performance eval + written exam
Developing coaches — skilled, credentialled, and accountable
ACC coaches have completed rigorous, ICF-approved training and logged at least 100 hours of real client work. They have passed both a performance evaluation and a written examination. This is the entry credential, but it already places a coach in the top tier of the profession — most practicing "coaches" hold no credential at all.
Walnut ACC coaches are available on the Starter plan, giving every client access to a verified, accountable professional from day one.
- 125+ hours training
- 500+ client hours
- Performance eval + CKA exam
Mid-tier professionals — experienced, tested, and deeply skilled
PCC coaches have logged at least 500 hours of client coaching and passed the Coach Knowledge Assessment, a rigorous exam covering core competencies. Their experience base is five times that of an ACC coach, and their skills have been independently verified against ICF standards.
The 2012 PwC/ICF Global Coaching Study found that clients working with PCC-level coaches reported significantly higher satisfaction and measurable behaviour change compared to those working with non-credentialled coaches.
- 200+ hours training
- 2,500+ client hours
- Portfolio review + performance eval
Elite coaches — fewer than 4% of all credentialled coaches globally
MCC is the highest credential the ICF awards. Coaches at this level have logged a minimum of 2,500 client hours and undergone a rigorous portfolio review and live performance evaluation. They demonstrate mastery-level competency across all ICF core areas.
Fewer than 4% of ICF credential holders worldwide have achieved MCC status. Walnut MCC coaches are reserved for Executive and Enterprise programmes.
Why this matters more than it seems
Coaching is an unregulated industry. Anyone can call themselves a coach, launch a website, and start charging. Without credential verification, organisations and individuals have no reliable way to distinguish trained professionals from unqualified practitioners.
No verified competency standard
Without ICF accreditation, there is no independent verification that a coach has been trained to any recognised standard. Weekend certifications and self-awarded titles are common.
No professional ethics accountability
ICF credential holders are bound by the ICF Code of Ethics and subject to an independent complaints process. Unaccredited coaches operate without this safeguard.
Measurably lower ROI
The 2012 PwC/ICF Global Coaching Study found that organisations using credentialled coaches reported significantly higher ROI than those using non-credentialled practitioners.
Organisational liability for corporate programmes
Companies that deploy unaccredited coaches risk reputational damage, duty-of-care failures, and ineffective spend. Credential verification is a basic governance requirement.
ICF verification on every coach
Every Walnut coach is independently verified against the ICF credential database before they join the platform. No exceptions.
Credential-matched programme tiers
Starter, Professional, and Executive programmes are matched to ACC, PCC, and MCC coaches respectively — so you always get the right level of expertise.
Expiry monitoring
ICF credentials must be renewed every three years. Walnut monitors renewal status and suspends access for any coach whose credential lapses.
Every Walnut coach is ICF verified before you meet them.
