Mentor coaching is one of the most misunderstood requirements on the path to the ICF ACC credential. Coaches who have completed their training hours and are ready to apply often discover they still need 10 hours of mentor coaching -- and they are not sure what that means, where to find it, or whether what they already have qualifies. This guide explains the mentor coaching requirement clearly: what it is, how group and individual hours differ, how to find a qualified mentor coach, what sessions actually look like, and how much you should expect to pay.
ICF requires 10 hours of mentor coaching to earn the ACC credential. At least 3 of those hours must be individual (1:1) sessions with a qualified mentor coach. The remaining hours can be completed in group settings. Sessions focus on observing your coaching and giving feedback on how well you demonstrate the ICF Core Competencies -- not on coaching you personally or teaching coaching techniques.
What Is ICF Mentor Coaching?
Mentor coaching is a formal process in which an experienced, ICF-credentialed coach observes your coaching practice and gives you structured feedback on how effectively you demonstrate the ICF Core Competencies. It is not coaching on your personal goals, therapy, or additional skills training. The focus is entirely on your coaching -- how you show up with clients, how you listen, how you evoke awareness, how you establish agreements.
ICF defines mentor coaching as "the provision of professional assistance in achieving and demonstrating the coaching competencies and skills appropriate for the desired ICF credential level." In practice, this means a mentor coach will either observe you coaching a live client or review a recorded session, then provide detailed, competency-specific feedback.
The purpose is two-fold. First, it ensures that coaches earning the ACC credential have been observed and evaluated by someone more experienced. Second, it accelerates your development in ways that peer practice alone cannot -- because you receive expert feedback tied to specific competency markers rather than general impressions.
Mentor coaching should not be confused with coaching supervision, which is a separate reflective practice focused on your overall professional development and wellbeing as a coach. Supervision is valuable but does not count toward the ICF mentor coaching requirement.
The 10-Hour Requirement: What Qualifies
To meet ICF's mentor coaching requirement for the ACC credential, you need a minimum of 10 hours completed over at least 3 months. At least 3 of those 10 hours must be individual (1:1) sessions. The remaining 7 hours can be completed in a group setting, typically with 5-10 coaches working with one mentor coach.
Your mentor coach must hold an ICF credential at the PCC or MCC level, or be a faculty member of an ICF-accredited Level 1 or Level 2 coaching program. A fellow ACC-credentialed coach cannot serve as your mentor coach, even if they are highly experienced.
A few things that do not count toward the requirement:
- Peer coaching (coaching each other with classmates)
- Coaching practice without qualified mentor feedback
- Supervision sessions focused on your wellbeing rather than competency demonstration
- Feedback from coaches who hold only an ACC credential
If you completed an ICF-accredited Level 1 or Level 2 program, your mentor coaching hours may already be built into your training. Check your program documentation carefully and confirm with your training provider which hours qualify and which do not. ICF sometimes audits applications and asks for documentation, so it is worth getting clarity before you apply.
Group vs. Individual Mentor Coaching: What to Expect
Both group and individual sessions count toward the 10-hour requirement, but they offer different experiences and serve different purposes in your development.
Individual Mentor Coaching (Minimum 3 Hours Required)
In a 1:1 session, you typically coach a volunteer client for 20-30 minutes while the mentor coach observes silently. Afterward, the mentor coach gives you detailed, competency-specific feedback -- what you did well, where you missed an opportunity, and what the ICF markers look like in practice. Some mentor coaches review recordings between sessions; others observe live. Either approach qualifies as long as the feedback is grounded in ICF competencies.
Individual sessions tend to be more intensive. Your mentor coach's full attention is on your coaching, so you receive more specific feedback and can ask follow-up questions tailored to your particular development edges. This is where most coaches report the largest leaps in self-awareness.
Group Mentor Coaching Sessions
Group sessions typically bring together 5-10 coaches under one mentor coach. One or two coaches demonstrate coaching during each session -- often with a volunteer client or in a fishbowl format -- and the whole group participates in the debrief. You learn from observing others and from hearing the mentor coach's analysis applied across different scenarios.
Group sessions are often more affordable and can be equally valuable, particularly for hearing how the same competency shows up differently across multiple coaches. The trade-off is less individual airtime: you may not coach in every session, and feedback is less personalized.
Many coaches find the most effective approach is to complete the required 3 individual hours alongside a group program that covers the remaining 7, gaining both personalized feedback and the perspective that comes from observing peers.
How to Find a Qualified Mentor Coach
Finding the right mentor coach is one of the decisions that most affects the quality of your mentor coaching experience. Here is where to look and what to evaluate.
Where to Search
The ICF Coach Finder at coachingfederation.org is the most reliable starting point. You can filter by credential level (PCC or MCC), specialty, and whether the coach offers mentor coaching services. Most coaches who offer mentor coaching say so in their profile.
Your coaching school is another natural first stop, particularly if you completed an ICF-accredited program. Many programs have established relationships with approved mentor coaches or faculty who offer standalone packages to alumni.
Coaching communities on LinkedIn and through ICF chapter networks often surface mentor coaches who are actively working with ACC candidates. Word of mouth from coaches who recently earned their ACC credential tends to be the most reliable source -- they can speak to whether the feedback was genuinely competency-specific or more general encouragement.
What to Ask Before Committing
Before signing on with a mentor coach, ask these questions:
- What credential do you hold? (Must be PCC or MCC, or faculty of an ICF-accredited program.)
- How many ACC candidates have you worked with?
- How do you structure feedback? (Look for explicit reference to ICF competency markers, not just general impressions.)
- Do you observe live sessions, recorded sessions, or both?
- What is your group session format? (Session length, group size, how coaching demonstrations are structured.)
Red Flags to Watch For
Be cautious of mentor coaches who cannot specify which ICF credential they hold, who offer "mentor coaching" that is primarily skills instruction rather than observation and feedback, or who cannot describe how their feedback connects to specific ICF Core Competencies. Unusually low-cost packages that pad hour counts with webinars or pre-recorded content rather than observed coaching practice are also worth scrutinizing.
The credential matters, but equally important is the mentor coach's ability to articulate competency markers clearly and give feedback you can act on.
What Happens in a Mentor Coaching Session
If you have never been observed as a coach, the first session can feel exposing. That vulnerability is part of the process -- and most coaches report that receiving expert feedback on their practice is one of the more valuable professional development experiences they have had.
A typical individual session runs 60-90 minutes. You coach for 20-30 minutes while your mentor coach observes (live or via recording). The remaining time is the debrief: your mentor coach shares specific observations tied to competency markers, asks you reflective questions about your choices, and highlights both strengths and areas to develop.
Group sessions are usually 90-120 minutes. One or two coaches in the group coach for the observation portion; the rest observe. The debrief involves the whole group, with the mentor coach inviting observations from participants before offering their own analysis.
In both formats, feedback is grounded in the 2019 ICF Core Competencies -- the same framework the ACC exam tests. You will hear language like "in this moment, you missed an opportunity to Evoke Awareness by staying curious rather than leading" or "your response here demonstrated strong Active Listening." That specificity is what makes mentor coaching fundamentally different from peer feedback.
How Much Does ICF Mentor Coaching Cost?
Mentor coaching represents a real investment, and costs vary significantly depending on format and the mentor coach's experience level.
Individual mentor coaching: $100-$300 per hour is a typical range, though highly experienced MCC-level mentor coaches may charge more. For the minimum 3 required individual hours, budget at least $300-$900.
Group mentor coaching programs: Structured programs designed to deliver the full 10-hour requirement range from $500 to $2,000+. These programs often bundle group and individual hours together, which can offer better value than sourcing each separately.
Bundled through a training program: If your coaching school includes mentor coaching as part of its curriculum, you may have already paid for it within your program tuition. Confirm how many hours are included and whether they meet ICF's qualification standards before purchasing additional hours.
If cost is a constraint, a group program that covers the full 10-hour requirement -- supplemented with just the minimum 3 individual hours -- is a practical approach. Group mentor coaching is substantive, not a second-tier option.

How Mentor Coaching Connects to the ACC Exam
Mentor coaching and the ACC exam serve different purposes, but they reinforce each other in an important way.
Mentor coaching develops your practical application of the ICF Core Competencies -- your ability to demonstrate them in a live session with a real client. The ACC exam tests your knowledge of those same competencies: what they mean, how to recognize them in a coaching transcript, and how to distinguish coaching from therapy, consulting, or advice-giving.
Coaches who complete mentor coaching before their exam often report that the feedback they received gives them a clearer mental model of what each competency looks like in practice -- which makes the knowledge-based exam questions easier to interpret. When you have heard your mentor coach explain what Cultivates Trust and Safety looks like in a real exchange -- and what undermines it -- the exam scenarios feel grounded in experience rather than abstract theory.
The competency areas covered in your ACC exam study plan map directly to the feedback you receive in mentor coaching: the 8 core competencies, the 2020 ICF Code of Ethics, and the boundaries of coaching practice. Treating mentor coaching and exam prep as parallel tracks -- not sequential steps -- is the most efficient path through the credentialing process.
If you want to reinforce your competency knowledge while working through your mentor coaching hours, CoachCertify's practice quizzes are organized by competency area, so you can deepen your understanding of the same frameworks your mentor coach is developing in your practice.

Frequently Asked Questions
How many mentor coaching hours are required for the ICF ACC credential?
ICF requires a minimum of 10 hours of mentor coaching, with at least 3 hours in individual (1:1) sessions. The remaining hours can be completed in group settings with up to 10 coaches per group. Hours must be completed over a minimum of 3 months.
What is the difference between group and individual mentor coaching?
Individual mentor coaching is a 1:1 session in which a qualified mentor coach observes your coaching and gives you competency-specific feedback. Group mentor coaching involves multiple coaches (typically 5-10) working with one mentor coach -- one or two coaches demonstrate coaching while the group observes, followed by a group debrief.
How much does ICF mentor coaching cost?
Individual sessions typically cost $100-$300 per hour. Group programs that cover the full 10-hour requirement range from $500-$2,000+. Costs vary based on the mentor coach's credential level, experience, and program structure.
Does my coach training program count toward my mentor coaching hours?
Possibly. If you completed an ICF-accredited Level 1 or Level 2 program, mentor coaching is often built into the curriculum. Verify with your program that the hours were delivered by a qualified mentor coach (PCC or MCC credentialed) and that they meet ICF's documentation requirements.
Does mentor coaching help with the ICF ACC exam?
Yes, indirectly. Mentor coaching deepens your understanding of the ICF Core Competencies through application and feedback -- the same knowledge the ACC exam tests. Pairing mentor coaching with structured exam practice is the most effective approach to preparing for both.
Conclusion
The 10-hour mentor coaching requirement is not an administrative hurdle -- it is one of the more substantive developmental experiences on the path to the ACC credential. Understanding what qualifies, choosing a mentor coach who gives genuinely competency-specific feedback, and approaching your sessions as an opportunity to internalize the ICF frameworks will make the process both more valuable and more efficient.
As you work through your mentor coaching hours, treat the same competency frameworks as your foundation for exam preparation. The two reinforce each other more than most candidates expect. Review the full ICF ACC credential requirements to make sure every piece is in place before you submit your application.
