One of the most common questions coaches have when pursuing ICF credentials is about mentor coaching hours. How many do you need? What counts as individual versus group hours? How do you track and document them? And — new for 2027 — who is qualified to deliver them? This guide explains the current ICF requirements for ACC, PCC, and MCC, plus the upcoming Mentor Coach Specialization (MCS) rule.
Quick answer: ICF requires 10 hours of mentor coaching for ACC, PCC, and MCC, with a minimum of 3 hours one-on-one, completed over at least 3 months. From January 1, 2027, any new mentor coaching hours that count toward an ACC, PCC, or MCC credential must be delivered by a Mentor Coach Specialization (MCS) mentor coach. Jump to the 2027 cutover →

Mentor Coach Credential Requirements (by Path)
Until January 1, 2027, ICF ties mentor coach qualifications to your application path:
- Level 1 / Level 2 / Portfolio (ACC or PCC): Mentor coach must hold a valid PCC or MCC credential. Source: ICF Mentor Coaching
- MCC Portfolio Path: Mentor coach must hold a valid MCC credential. Source: ICF Mentor Coaching
- ACC-specific exception: In some ACC paths, an ACC coach who has renewed at least once may qualify; check your exact path requirements. Source: ACC Credential Requirements

What changes from January 1, 2027: the MCS rule
ICF is introducing a Mentor Coach Specialization (MCS) and tightening who can deliver credential-bearing mentor coaching.
The new rule, plainly: From January 1, 2027, any new mentor coaching hours that count toward an ACC, PCC, or MCC credential must be delivered by an MCS mentor coach. Hours completed before that date with a then-qualified mentor coach are still accepted. Source: ICF — Mentor Coaching Requirement Replacing ACC & PCC Performance Evaluations
A separate but linked change: from April 1, 2027, ACC/PCC Portfolio candidates no longer submit a Performance Evaluation recording. Competence is demonstrated through enhanced mentor coaching, including a Competency Review Form completed by your MCS mentor coach. MCC Performance Evaluation is unaffected.
What this means for your hour planning:
- Hours you already banked are safe. If your mentor coach was qualified at the time, the hours count even after January 1, 2027.
- Don't book new hours past December 31, 2026 with a non-MCS coach if those hours are for credential evidence. Confirm MCS status before you commit.
- The 10-hour total and the 3-month minimum don't change. Only the who changes — and, for ACC/PCC Portfolio, what gets submitted at the end.
For the full timeline and submission package, see ACC & PCC Performance Evaluation Changes 2027 and the ICF MCS 2027 Readiness Checklist.
Individual vs. Group Mentor Coaching: What's the Difference?
Understanding the distinction between individual and group mentor coaching helps you plan your hours strategically. For a deeper dive into which format suits your situation, see our group vs. individual mentor coaching comparison.
Individual Mentor Coaching
Individual mentor coaching is a one-on-one session between you and your mentor coach. During these sessions:
- All attention is on you: Your mentor coach focuses exclusively on your development
- Deeper exploration: More time to unpack complex situations or competency challenges
- Personalized feedback: Feedback is tailored specifically to your coaching style and growth areas
- Confidentiality: You can share sensitive client situations without concern about group dynamics
- Flexibility: Sessions can be scheduled based on mutual availability
Best for:
- Initial assessment of your current competency level
- Working on specific, persistent challenges
- Preparing for credential assessment
- Discussing sensitive coaching situations
- Coaches who prefer dedicated attention
Group Mentor Coaching
Group mentor coaching involves one mentor coach working with multiple coaches simultaneously (ICF allows up to 10 participants). These sessions offer:
- Peer learning: Observe other coaches receive feedback and learn from their development
- Diverse perspectives: Multiple viewpoints on coaching approaches and challenges
- Cost efficiency: Generally less expensive per hour than individual sessions
- Community building: Connect with coaches at similar stages of development
- Normalized experience: Realize that others face similar challenges
Best for:
- Learning from diverse coaching styles
- Building a peer community
- Cost-conscious development planning
- Coaches who thrive in collaborative environments
- Ongoing practice between intensive individual sessions
Making the Choice
Most coaches benefit from a blend of both formats. Consider this approach:
- Start with individual sessions to establish your development baseline and build relationship with your mentor coach
- Use group sessions for ongoing practice, peer learning, and cost-effective development
- Return to individual sessions for targeted work on specific challenges and final credential preparation

Accurate tracking is essential for your ICF application. Here's how to document your hours effectively.
What to Record
For each mentor coaching session, document:
- Date of session
- Duration (in hours and minutes)
- Format: Individual or group
- Mentor coach name
- Mentor coach ICF credential (ACC, PCC, or MCC)
- Mentor coach credential number
- Brief description of what was covered
Documentation Methods
Spreadsheet Tracking
Create a simple spreadsheet with columns for each element above. This gives you a clear overview and easy totaling of hours.
Date | Duration | Type | Mentor Coach | Credential | Topics Covered
-----|----------|------|--------------|------------|---------------
1/15 | 1.0 hr | Ind | Jane Smith | PCC-12345 | Active listening
1/22 | 1.5 hr | Group| Jane Smith | PCC-12345 | Powerful questions
Mentor Coach Documentation
Your mentor coach should provide documentation of your hours. Most experienced mentor coaches have systems for this. Request:
- A log of all sessions with dates and durations
- Confirmation of their ICF credential status
- A summary letter if needed for your application
Platform Tracking
If you're using a mentor coaching platform or technology solution like Mentor Coaching AI, automated tracking features can document your hours, sessions, and development progress.
Verification Requirements
The ICF may verify your mentor coaching hours. Be prepared to provide:
- Contact information for your mentor coach(es)
- Documentation proving the mentor coach's credential was active during your sessions
- Records showing dates, durations, and format of each session
Keep your documentation for at least three years after receiving your credential, as it may be needed for renewal or audit purposes.
Common Questions About Mentor Coaching Hours
Can I Use Multiple Mentor Coaches?
Yes. You can work with different mentor coaches for your individual and group hours, or even split individual hours between coaches. Benefits of multiple mentor coaches include:
- Diverse feedback perspectives
- Different areas of expertise
- Schedule flexibility
Just ensure each mentor coach holds the appropriate credential level for your target path.
Do Hours Expire?
Mentor coaching must be completed over a minimum of three months. ICF updates requirements periodically, so always confirm your current path.

What About Hours from My Coach Training Program?
Many ICF-accredited coach training programs include mentor coaching as part of their curriculum. These hours typically count toward your requirement if:
- The mentor coach holds the appropriate ICF credential
- The sessions meet ICF mentor coaching definitions (focused on coaching competencies, includes observation)
- The program provides proper documentation
Check with your training program and review ICF requirements to confirm your training-included hours qualify.
Can I Get Mentor Coaching and Training Hours Simultaneously?
No. The ICF distinguishes between training (learning coaching skills) and mentor coaching (receiving feedback on your coaching practice). A single session cannot count for both. If you're in a training program, the mentor coaching component should be clearly separated from instructional time.
What If My Sessions Are Longer Than One Hour?
Log the exact duration of each mentor coaching interaction (for example, 60 or 90 minutes), and keep your documentation consistent across sessions.
Strategic Planning for Your Hours
For ACC Candidates
Recommended approach:
- Start with 2-3 individual sessions to assess your current level
- Complete 4-5 group sessions for peer learning and practice
- Finish with 2-3 individual sessions focused on your specific growth areas and assessment preparation
Timeline suggestion: Complete your hours over 3-6 months, allowing time to practice between sessions.
For PCC Candidates
Recommended approach:
- Begin with individual sessions to identify PCC-level development areas
- Use group sessions to refine your skills with peer feedback
- Focus final individual sessions on demonstrating consistent PCC-level competencies
Timeline suggestion: 4-8 months provides adequate time for the deeper development expected at PCC level.
For MCC Candidates
Recommended approach:
- Prioritize one‑on‑one sessions early to get deep feedback
- Use group sessions selectively for peer learning
- Work with an MCC‑credentialed mentor coach if you’re on the MCC Portfolio Path

Frequently Asked Questions
How quickly can I complete my 10 hours?
ICF requires the 10 hours to be completed over a minimum of three months.
Source: ICF Mentor Coaching
What happens if I don't complete all required hours?
Your credential application cannot be submitted until you've completed all mentor coaching hours. Ensure you have proper documentation before beginning your application.
Who is qualified to provide mentor coaching?
Until December 31, 2026, ICF requires a mentor coach with an active credential at or above the level you're applying for (ACC, PCC, or MCC), with an ACC exception for certain ACC applicants. Source: ICF Mentor Coaching
From January 1, 2027, any new mentor coaching hours that count toward an ACC, PCC, or MCC credential must be delivered by a mentor coach who holds the Mentor Coach Specialization (MCS). Source: ICF — Introducing the Mentor Coach Specialization
Do I need an MCS mentor coach for hours I already completed?
No. Hours completed before January 1, 2027 with a then-qualified mentor coach remain valid. Only new hours from that date onward need to be with an MCS mentor coach. If your engagement spans the cutover, talk to your mentor coach about which side of the line each session falls on.
Does group size affect whether hours count?
ICF limits group mentor coaching to no more than 10 participants.
Source: ICF Mentor Coaching
What if my mentor coach's credential lapses during our work together?
Hours completed while your mentor coach held an active credential remain valid. However, any subsequent hours would not count. Verify your mentor coach's credential status periodically, especially for longer engagements.
Can I count mentor coaching I received before deciding to pursue a credential?
Potentially, if the sessions meet all ICF requirements and fall within the acceptable timeframe. Review ICF policies and consult with your mentor coach about documentation.
Your Next Steps
Understanding mentor coaching hour requirements is the first step. Here's how to move forward:
- Determine your credential path. ICF requires 10 hours over 3+ months, with at least 3 hours one-on-one.
- Decide which side of the 2027 cutover your hours land on. Hours before January 1, 2027 use existing rules; hours from that date forward need an MCS mentor coach. See the MCS 2027 readiness checklist.
- Confirm mentor coach qualifications. Today: PCC/MCC depending on path. From 2027: MCS. See how to find the right mentor coach for your ICF journey for a practical vetting checklist.
- Create a timeline. Plan when you'll complete your hours relative to your target application date — and whether you submit a Performance Evaluation under the old rules or a Competency Review Form under the new ones. The ultimate guide to mentor coaching for ICF credentials has detailed planning advice for each stage.
- Set up tracking. Establish your documentation system before your first session.
- Maximize between-session development. Use tools like Mentor Coaching AI to practice between sessions so each mentor coaching hour is focused on growth, not gap discovery.
Your mentor coaching hours are among the most valuable investments in your coaching career. With proper planning and documentation, you'll meet ICF requirements while genuinely developing your coaching competencies.
