If you're pursuing ICF credentials, you'll need to complete mentor coaching hours. The question many coaches face: should you invest in individual mentor coaching, group mentor coaching, or some combination of both?
Both formats meet ICF requirements when properly structured. Both can accelerate your development as a coach. But they offer distinctly different learning experiences, come at different price points, and serve different development needs.
And in 2027, the stakes of this choice change. The ICF is introducing the Mentor Coach Specialization (MCS) and, for Portfolio candidates, replacing the recorded performance evaluation with documentation your mentor coach produces across the engagement. That shifts real weight onto who runs your group and where your observed sessions happen. This guide covers the classic group-vs-individual decision first, then walks through exactly what the 2027 rules change.

Understanding ICF Mentor Coaching Requirements
Before comparing formats, let's clarify what ICF requires. For a thorough breakdown of hour counts, timelines, and documentation, see the ICF mentor coaching hours requirements guide.
ICF Requirements (Current Snapshot)
- 10 total hours of mentor coaching
- Minimum 3 hours one‑on‑one — the remaining 7 can be group
- Group ratio of at least one mentor coach per 10 participants
- Completed over a minimum of 3 months (12 full weeks between first and final session)
Source: ICF Mentor Coaching and the ICF Mentor Coach Handbook
Note the wording on group size: ICF frames it as a ratio (one mentor coach to every 10 participants), not a hard cap of 10 people in the room. In practice most groups stay at 10 or fewer with a single facilitator.
What Qualifies as Mentor Coaching?
ICF defines mentor coaching as feedback on observed coaching aligned to the Core Competencies. This includes:
- Observed coaching with feedback
- Discussion of coaching competencies
- Guidance on competency development
- Feedback on recorded sessions
Group hours qualify only when the sessions focus on developing the participants' coaching skills in alignment with the ICF Core Competencies — a group class about coaching topics doesn't count.
What Changes in 2027 — and Why It Reshapes This Choice
The 2027 credentialing changes don't touch the 10-hour total, the 3-hour individual floor, or the group ratio. What they change is who can deliver your hours and how your skills get validated. Three things matter for the group-vs-individual decision.
Who can run your group after January 1, 2027?
From January 1, 2027, all new mentor coaching hours counted toward an ICF credential must be delivered by a mentor coach holding the Mentor Coach Specialization at a qualifying level:
- ACC candidates may work with an MCS‑ACC or MCS‑PCC mentor coach
- PCC applicants need an MCS‑PCC mentor coach
- MCC applicants need an MCS‑MCC mentor coach
The full matching logic — including renewals — is in our MCS badge matching guide. For group programs the practical consequence is simple: before you commit to a cohort whose sessions run past December 31, 2026, confirm the facilitator's MCS status at your target level. A group led by a credentialed but non‑MCS mentor coach stops producing credit‑bearing hours at the cutover.
Where do the Session Observation Forms fit if I'm in a group?
This is the question we see most often in coaching communities right now, and it's worth being precise about what ICF has actually published.
Under the new model, your mentor coach must observe and review at least three of your own coaching sessions — recordings of (or live observation of) you coaching a real client, with the client's written permission. Each observed session produces a Session Observation Form; at the end of the engagement, the mentor coach completes a Competency Review Form summarizing your demonstrated skills across all observed sessions. From April 1, 2027, ACC and PCC Portfolio applicants submit that Competency Review Form instead of the old performance-evaluation recording and transcript, and keep the Session Observation Forms on file in case ICF requests them. (Details in our performance evaluation changes guide.)
Two implications for group formats:
- The observation attaches to your client sessions, not to the group meetings. Attending seven hours of group discussion is not, by itself, observed coaching. The ICF Mentor Coach Handbook anchors the Session Observation Form in the one‑to‑one track: the mentor coach reviews your recording as prep work, completes the form, and structures the individual session around it.
- Your three individual hours now carry structural weight. They're where the review of your observed sessions naturally lives. A group program that treats the 1:1 hours as an afterthought is a poor fit for the 2027 model.
The Handbook does list group review of a member's recording as an optional group activity, but ICF has not stated whether observation done that way can generate a Session Observation Form. Until it does, the safe assumption for Portfolio candidates is that your documented observations run through the individual track — ask any group provider how they handle this before you enroll.
Does timing change the math?
If you're mid-decision on when to do your hours, the short version: hours completed under current rules don't expire, but the mentor you can use changes on January 1, 2027, and what Portfolio applicants submit changes on April 1, 2027 (with a January–March window where either route works). The full decision guide is in Complete Your Mentor Coaching Before 2027 — or Wait?
Individual Mentor Coaching: Deep Personalized Development
What Individual Mentor Coaching Looks Like
In individual mentor coaching, you work one-on-one with a mentor coach who:
- Reviews your coaching recordings
- Provides detailed competency feedback
- Observes your live coaching (where applicable)
- Creates personalized development plans
- Addresses your specific challenges and questions
Sessions focus entirely on your development and the feedback your mentor coach provides. Under the 2027 model, this is also where your Session Observation Forms are reviewed with you.
Advantages of Individual Mentor Coaching
Personalized Attention Every moment is focused on your coaching. Your mentor can dive deep into your specific patterns, challenges, and growth edges. There's no sharing time with other participants.
Confidential Environment Some coaches feel more comfortable receiving feedback privately. You can discuss challenges, blind spots, and struggles without peer observation.
Flexible Scheduling Individual sessions can often be scheduled around your availability rather than finding times that work for a group.
Tailored Curriculum Your mentor can focus on exactly what you need most. If establishing agreements is your growth edge, the entire session can address that competency.
Deeper Relationship Working individually allows a stronger mentor relationship to develop, which some coaches find accelerates their learning and confidence.
Challenges of Individual Mentor Coaching
Higher Cost One‑on‑one mentoring is typically more expensive than group formats. Pricing varies by provider, credential level, and location.
Limited Perspectives You only receive one mentor's perspective on your coaching. Different mentors might notice different things or offer alternative viewpoints.
No Peer Learning You miss the opportunity to learn from watching others receive feedback or from hearing about other coaches' challenges and insights.
Self-Focus Can Be Limiting Sometimes hearing other coaches' sessions illuminates aspects of your own coaching you wouldn't have noticed otherwise.

What Group Mentor Coaching Looks Like
Group mentor coaching brings together multiple coaches with a mentor coach facilitator (at a ratio of at least one mentor coach per 10 participants). Typical activities include:
- Participants presenting coaching recordings
- Group observation and feedback
- Mentor coach competency guidance
- Peer discussion and reflection
- Collaborative learning exercises
Sessions are structured to allow time for multiple participants to receive feedback.
Advantages of Group Mentor Coaching
Cost Efficiency Group formats spread facilitator costs across participants, so per‑person costs are often lower than individual sessions.
Peer Learning Opportunities Watching other coaches receive feedback teaches you about your own coaching. You'll notice patterns, learn techniques, and gain insights you wouldn't access individually. A moment coaches describe again and again: hearing a peer's recording paused at a silence, and suddenly understanding what your own rushed transitions cost your clients.
Multiple Perspectives Group members offer diverse viewpoints on coaching demonstrations. This variety can surface observations a single mentor might not make.
Normalizing the Development Journey Hearing that other coaches struggle with similar challenges reduces isolation and self-criticism. Peer community provides emotional support.
Developing Feedback Skills Providing feedback to peers strengthens your ability to observe and articulate coaching competencies—a skill valuable for your own self-assessment.
Challenges of Group Mentor Coaching
Less Individual Attention Time is divided among participants, so your individual feedback window is smaller than in one‑on‑one sessions.
Fixed Scheduling Group sessions happen at set times. If you have an irregular schedule, finding compatible groups can be difficult.
Variable Participant Quality Your experience depends partly on who else is in the group. Participants at very different skill levels can make sessions less valuable.
Less Confidential You're receiving feedback in front of peers. Some coaches feel more vulnerable in this setting, which can limit what they're willing to explore.
Pace May Not Match Your Needs Group curriculum addresses common themes rather than your specific development priorities.
Comparing the Formats: Key Considerations
Learning Style Fit
Choose Individual If You:
- Process feedback better in private settings
- Have specific, unique development needs
- Want maximum scheduling flexibility
- Prefer deep focus over breadth of exposure
- Feel inhibited receiving feedback in groups
Choose Group If You:
- Learn well from observing others
- Value community and peer support
- Work well with fixed scheduling
- Appreciate diverse perspectives
- Are comfortable with public feedback
Budget Considerations
Pricing varies widely by provider and region. Compare what's included (session length, feedback depth, documentation, and mentor coach credential level) rather than focusing only on hourly rates. One 2027-era detail worth checking: time your mentor coach spends reviewing your recordings and completing Session Observation Forms does not count toward your 10 hours per the ICF Mentor Coach Handbook — so ask whether that review work is included in the price or billed separately.
Development Stage Considerations
Early in Your Coaching Journey Group settings can be particularly valuable early in development when you're still learning what good coaching looks like. Seeing multiple examples accelerates pattern recognition.
Advanced Development As you approach PCC or MCC level, individual attention becomes more valuable. Advanced development requires nuanced feedback on subtle coaching distinctions that groups may not have time to address.
Preparing for Skills Validation Individual sessions are most valuable when preparing the coaching that will be formally assessed — whether that's a performance-evaluation recording (Portfolio applications through March 31, 2027) or the observed sessions behind your Competency Review Form (from April 1, 2027). Either way, you need detailed feedback on your specific demonstration sessions.
The Hybrid Approach: Combining Both Formats
Many coaches find that combining formats optimizes their development:
Sample Hybrid Structure
Phase 1: Group Foundation (Months 1-2)
- 4-5 hours of group mentor coaching
- Focus: Understanding competencies, seeing diverse coaching styles
- Benefit: Cost-effective broad exposure
Phase 2: Individual Deep Dive (Months 3-4)
- 3 hours of individual mentor coaching
- Focus: Personal patterns, review of your observed client sessions
- Benefit: Tailored attention to your growth edges — and, under the 2027 model, the natural home of your Session Observation Form reviews
Phase 3: Group Integration (Month 5)
- 2-3 hours of group mentor coaching
- Focus: Testing new skills, receiving peer feedback
- Benefit: Validating development, community support
This structure meets ICF requirements while maximizing the benefits of each format. (The intake and closing sessions of a structured engagement count toward the 10 hours, per the ICF Mentor Coach Handbook.)
When to Prioritize Individual Sessions
Reserve your individual hours for:
- Observed-session review: Detailed feedback on the client sessions your mentor coach observes and documents
- Challenging growth edges: Issues that require deep exploration
- Credential-specific guidance: Navigation of the application process
- Confidential concerns: Topics you're not comfortable discussing in groups

Making Your Decision
Questions to Ask Yourself
- What's my learning style? Do I learn better from focused attention or diverse exposure?
- What's my budget? How much can I invest, and where do I want to allocate those funds?
- What's my schedule like? Can I commit to group times, or do I need individual flexibility?
- Where am I in my journey? Am I building foundations or refining advanced skills?
- When will my hours land? If any fall on or after January 1, 2027, my mentor coach's MCS status becomes a requirement, not a nice-to-have.
Questions to Ask Potential Providers
For Group Programs:
- What's the group size and mentor-coach-to-participant ratio?
- Does the facilitator hold (or have a plan to hold) the MCS at my target credential level?
- How are the 3 individual hours structured, and who delivers them?
- How do you handle Session Observation Forms and the Competency Review Form for Portfolio candidates?
- Is recording-review time included in the price, given it doesn't count toward the 10 hours?
For Individual Mentors:
- What credential level do you hold — and will you hold the MCS at my level in 2027?
- How do you structure feedback sessions?
- What's your approach to competency development?
- How many of my client sessions will you observe, and how do you document them?
- How do you handle preparation for skills validation?
Frequently Asked Questions
Can I fulfill all my mentor coaching hours with group sessions?
No. ICF requires at least 3 hours one‑on‑one; the remaining 7 hours can be group sessions (at a ratio of one mentor coach per 10 participants). Under the 2027 model those individual hours also anchor the observation and documentation of your own coaching. Source: ICF Mentor Coaching
Who qualifies to be my mentor coach?
Through December 31, 2026: a mentor coach holding a renewed ICF credential appropriate to your level. From January 1, 2027: a mentor coach holding the Mentor Coach Specialization at a qualifying level — MCS‑ACC or MCS‑PCC for ACC candidates, MCS‑PCC for PCC applicants, MCS‑MCC for MCC applicants. See the MCS badge matching rules. Source: ICF: Introducing the Mentor Coach Specialization
Do Session Observation Forms get completed during group sessions?
ICF anchors the Session Observation Form in the individual track: your mentor coach reviews a recording (or live observation) of you coaching a real client and completes the form as prep for your one-to-one session. Group review of a member's recording exists as an optional group activity in the ICF Mentor Coach Handbook, but ICF hasn't stated that it can generate observation documentation — ask your provider how they handle it. Source: ICF Mentor Coach Handbook
How do I find qualified mentor coaches?
Look for mentor coaches who hold ICF credentials at or above the level you're pursuing — and, for hours delivered from 2027 on, the MCS at your target level. See our detailed guide on how to find the right mentor coach for your ICF credentials for a vetting checklist and questions to ask.
Is online mentor coaching as effective as in-person?
ICF focuses on observed coaching sessions and competency‑based feedback; confirm your mentor coach's format and documentation practices. Source: ICF Mentor Coaching
How far in advance should I start mentor coaching?
ICF requires mentor coaching to span a minimum of three months — 12 full weeks between your first and final sessions — so plan early enough to meet that timeline. If you're weighing whether to finish before the 2027 cutover, see the timing decision guide. Source: ICF Mentor Coach Handbook
Can I use mentor coaching from my original training program?
If your ICF‑accredited training (e.g., Level 1/2) includes mentor coaching that meets ICF requirements, those hours can count. Verify with your provider and the current ICF guidelines — and for cohorts spanning January 1, 2027, confirm how the program handles the MCS requirement. Source: ICF Coaching Education Requirements
The choice between group and individual mentor coaching isn't either/or for most coaches—it's finding the right blend that serves your learning, budget, and development needs. The 2027 rules don't change that; they just raise the bar on vetting: an MCS-qualified facilitator, individual hours that do real observational work, and documentation handled properly. Both formats, properly utilized, will advance your coaching competence and prepare you for successful credentialing. The ultimate guide to mentor coaching for ICF credentials covers how to integrate both formats into a coherent development plan.
