ICF Mentor Coach Specialization (MCS): What's Changing Before 2027

The ICF Mentor Coach Specialization (MCS) is a new credential for mentor coaches, announced by the International Coaching Federation in April 2026. Starting January 1, 2027, all new mentor coaching hours for ACC, PCC, and MCC candidates must come from a mentor coach who holds the MCS. Starting April 1, 2027, the Performance Evaluation (recorded coaching session) requirement is eliminated for ACC and PCC Portfolio applicants, replaced by an enhanced mentor coaching model with ongoing observation and feedback.

Key Takeaways

  • January 1, 2027: All new mentor coaching hours must be delivered by an MCS-qualified mentor coach, for every credential level (ACC, PCC, MCC).

  • April 1, 2027: The Performance Evaluation recording is removed for ACC and PCC Portfolio candidates. MCC Performance Evaluation remains unchanged.

  • What replaces it: Your MCS-qualified mentor coach will complete a Session Observation Form after each session and a cumulative Competency Review Form at the end of your mentoring engagement.

  • Hours completed before January 1, 2027 with a mentor coach who was properly qualified at the time still count. No credit is lost retroactively.

  • If you are looking for a mentor coach right now, ask whether they have earned or are actively pursuing their MCS before you commit to working together.

If you are working toward your ICF credential right now, or you are looking for a mentor coach to support that process, you have probably seen the letters "MCS" floating around. Maybe your coach training program mentioned it. Maybe a colleague forwarded a confusing email thread. Maybe you saw "MCQ" in one place and "MCS" in another and wondered whether you missed something.

You did not miss anything. The name changed early on. The requirement is real. And it affects you whether you are pursuing a credential or choosing a mentor coach.

Amy Magyar, owner of FromWithin Coaching, went through this confusion as well. She is an ICF Mentor Coach with over 20 years in the coaching community, and when ICF announced the MCS, she spent more time than she would like to admit trying to piece together what was actually required, what the deadlines meant, and what had changed from the original announcement. The information was scattered. The language kept shifting. It was not clear.

Once she found the path through it, she made a decision: she wanted to make this seamless for every coach who comes after her. That is what her prior post wass for.

What Is the ICF Mentor Coach Specialization (MCS)?

The MCS is a credential for mentor coaches themselves. It was announced by ICF in April 2026 and takes effect January 1, 2027.

Until now, any coach holding an active PCC, MCC, or renewed ACC could offer mentor coaching to a candidate working toward their own credential. There was no separate training requirement, no formal evaluation, and no standardized process for how mentor coaching was delivered. The quality of that mentoring varied widely.

The MCS changes that. It establishes a recognized standard for mentor coaching, built around a defined competency framework that ICF published in September 2024. Mentor coaches who earn the MCS have completed specific education in mentor coaching competencies, evaluation methods, and developmental feedback practices.

Two practical things happen when a mentor coach earns the MCS:

  1. They receive an MCS badge from ICF.

  2. They appear on ICF's public Mentor Coach Registry.

After January 1, 2027, only coaches holding the MCS will appear on that registry.

The Two Dates That Matter: January 1 and April 1, 2027

This is where most of the confusion lives, so we want to make this as clear as possible. There are two separate deadlines, and they address two different things.

January 1, 2027: Who Can Mentor You

Starting on this date, any new mentor coaching hours you complete toward an ACC, PCC, or MCC credential must be delivered by a mentor coach who holds the MCS. If you are renewing your ACC, or using mentor coaching as part of your continuing development for PCC or MCC renewal, the same rule applies.

One important note: Hours you completed before January 1, 2027, with a mentor coach who was properly qualified under the rules at that time, still count toward your credential. You do not lose credit retroactively. This applies only to new hours going forward.

April 1, 2027: How You Are Evaluated

On this date, the Performance Evaluation requirement, the recorded coaching session and transcript that ACC and PCC Portfolio candidates have submitted for years, is eliminated.

In its place, your MCS-qualified mentor coach will document your growth through two new forms:

  1. Session Observation Form: Completed after each one-on-one mentoring session, capturing what was observed about your coaching skills.

  2. Competency Review Form: A cumulative assessment completed at the end of your mentoring engagement, documenting your overall competency development.

This is a meaningful shift. Instead of demonstrating your coaching ability through a single recorded snapshot, your development is validated over time through real observation by a trained mentor coach.

For MCC candidates: The Performance Evaluation requirement (two recorded coaching sessions) remains in place. ICF has stated that any changes to the MCC process will be reviewed separately beginning in 2027.


Who Needs to Care About the MCS?

Coaches Pursuing ACC or PCC Credentials (or recredentialing every three years)

If you are actively working with a mentor coach in 2026, nothing changes yet. Your current mentor coach, if they hold an active PCC, MCC, or renewed ACC, is fully qualified under today's rules.

But if your mentoring engagement is going to stretch into 2027, or if you have not started your mentor coaching hours yet, this is the time to ask your prospective mentor coach directly: Have you earned your MCS? If not, when do you expect to have it?

If you are a Portfolio candidate for ACC or PCC and you are close to finishing before April 2027, you can likely still complete your credential through the Performance Evaluation pathway as it exists today. If your timeline pushes past that date, plan for the new formative evaluation process instead.


Coaches Pursuing MCC

The MCS still affects you. Starting January 1, 2027, your new mentor coaching hours must come from an MCS-qualified mentor coach. However, your Performance Evaluation requirement stays in place for now.


Coaches Looking to Hire a Mentor Coach

If you are searching for a mentor coach to support your credentialing work, the MCS gives you something you have not had before: a clear, verifiable way to know that your mentor coach has been trained in mentor-specific competencies.

Before the MCS, a mentor coach only needed to hold the right credential level. Now, the MCS tells you they have completed dedicated education in observing coaching, providing competency-based feedback, and evaluating coaching readiness according to ICF standards.

Here is what to look for:

  1. Ask whether they hold the MCS designation.

  2. Check the ICF Mentor Coach Registry (after January 1, 2027, only MCS holders will be listed).

  3. Confirm that their MCS level matches your target credential. The MCS is issued at three levels (ACC, PCC, MCC), and your mentor coach needs to hold the MCS at the level you are pursuing.

Coaches Pursuing Credentials Through a Level 1 or Level 2 Program

If you are going through an ICF-accredited coaching education program rather than the Portfolio path, your program is expected to incorporate the new mentor coaching requirements. You may not need to manage this separately. However, it is still worth confirming with your program how they are handling the transition.

What Happened to the "MCQ"?

If you saw the term "MCQ" (Mentor Coach Qualification) before seeing "MCS," you are not confused. ICF initially used the term MCQ and later updated the name to Mentor Coach Specialization (MCS). They are the same thing. The current, official name is MCS.

How Do Mentor Coaches Earn the MCS?

This section is for mentor coaches, or coaches considering becoming mentor coaches. ICF offers two application pathways:

FAQ

Do my existing mentor coaching hours still count?

Yes. Hours completed before January 1, 2027, with a mentor coach who was qualified under the rules at that time, are still accepted toward your credential application. You do not lose credit retroactively.


Can I still get my ACC or PCC if I submit my application before the deadlines?

If you complete your mentor coaching hours before January 1, 2027, under the current rules, and submit your application before the relevant deadlines, those hours and requirements still apply as they stand today.


What if my mentor coach does not have the MCS yet?

If you are completing mentor coaching hours after January 1, 2027, those hours need to come from an MCS-qualified mentor coach to count toward your credential. If your current mentor coach is working toward their MCS but does not hold it yet, ask them about their timeline and have a backup plan.


Does this affect coaches outside the United States?

Yes. The MCS is a global ICF requirement. It applies to all ICF credential candidates regardless of location.


What are the ICF Mentor Coaching Competencies?

ICF published a set of six mentor coaching competencies across four domains in September 2024: Foundation, Process Management, Client Development, and Group Mentor Coaching. These competencies form the basis of MCS education and evaluation.


The Bigger Picture

We understand the frustration. When ICF first announced this, the information was not easy to find, the terminology shifted, and the timeline had layers that were not immediately obvious. so many coaches lived that confusion.

But here is how we have come to see it after watching Amy go through the process: this change is not about adding hoops. It is about making sure that when you invest in a mentor coach, that person has been specifically trained to observe your coaching, give you competency-based feedback, and support your development over time. You deserve a mentor coach who was trained to mentor, not just someone who holds the right credential level.


If you are pursuing your ACC, PCC, or MCC, keep your eyes on those two dates: January 1, 2027, and April 1, 2027. Ask questions of whoever is mentoring you. And if the whole thing still feels confusing, you do not have to sort through it alone.


Amy Magyar holds a weekly Ask Me Anything for Coaches where she talks through exactly these kinds of questions in real time. No pitch, no agenda. Just straight answers from someone who has been in this community for over 20 years and just went through the MCS process herself.



Let's get ready for it together.
