I submitted my MCC performance evaluation recordings in April 2026 and I am in the review window right now.
That means I have spent a lot of the last year in the mentor coaching relationship. Being mentored. Being calibrated. Sitting with the discomfort of hearing myself on a recording and realizing that the coach I thought I was and the coach the assessors are going to see are two slightly different people.
Mentor coaching is the part of ICF credentialing that saved me. I do not think I would be in this review window without it.
Which is why the change ICF just made to who is allowed to be a mentor coach matters so much. If you are a PCC or an MCC who has been mentoring credential candidates, or you are thinking about becoming a mentor coach, this affects you directly.
TL;DR
- Starting January 1, 2027, only mentor coaches holding the Mentor Coach Specialization (MCS) can provide the mentor coaching required for ACC, PCC, and MCC credential applications.
- The MCS comes in three levels: MCS-ACC, MCS-PCC, MCS-MCC. You mentor at or below your level.
- There are two application paths. Most mentor coaches only know about one of them.
- The Credit for Prior Learning path exists specifically for coaches who have been mentoring credential candidates informally, outside of a school engagement. If that is you, read on.
- Applications are open now. The handbook is live on coachingfederation.org.
What the January 1, 2027 change says
Beginning January 1, 2027, mentor coaching that counts toward an ICF credential (ACC, PCC, or MCC) must be delivered by a coach who holds the Mentor Coach Specialization at the corresponding level. The three levels are MCS-ACC, MCS-PCC, and MCS-MCC. An MCS-PCC can mentor ACC and PCC candidates. An MCS-MCC can mentor at all three levels.
This is a significant departure from how mentor coaching has worked for most of ICF's history. Until now, being an active PCC or MCC in good standing was enough to qualify you as a mentor coach. That is changing. Under the new model, holding the credential is the floor, not the ceiling. The MCS is the credential that says you are trained specifically in how to mentor, how to give calibrated feedback against the markers, and how to guide a candidate through the credentialing process.
The reason ICF gave for this change is worth reading. They are also replacing the performance evaluation for ACC and PCC Portfolio path candidates in April 2027, so mentor coaches are about to hold significantly more weight in whether a candidate advances. A recording sent off to a distant assessor is being replaced by a mentor coach who observes over time, calibrates against markers, and signs off when the candidate is ready. That is a serious responsibility. ICF wants the people carrying it to be trained for it.
The two paths, and the one most people miss
There are two ways to earn the MCS.
The Standard Path is what most coaches are hearing about. You hold an active PCC, MCC, or renewed ACC. You complete at least 41 hours of mentor coaching education aligned with the ICF Mentor Coaching Competencies, with at least 50% delivered synchronously (live instruction). Then you apply.
Straightforward. Expensive and time-consuming, but the requirements are clear.
The other path is Credit for Prior Learning. And this is the one I want to spend a minute on, because I saw a post from Daniela Baur in the ICF Facebook group a few weeks ago that made me realize how many mentor coaches do not know this path exists.
Daniela wrote something like: I have mentored a few coaches who had already completed their official 10 hours of mentor coaching through their training program. I gave them additional mentoring outside of that engagement, helped them prepare for the exam, sat with them through the process. When they submitted their applications, there was no way to list me as their mentor coach. Does that mentoring count toward anything?
I read that and thought: this is exactly the person the Credit for Prior Learning path was built for.
The path is designed for mentor coaches who have already accumulated substantial mentor coaching experience and have supported multiple candidates through the credentialing process. It recognizes that a lot of real mentor coaching happens outside of the formal school-assigned engagement. Peer-to-peer mentoring. Post-training support. Preparation coaching that ran for months after the official hours ended. That work is real. ICF is now saying it should count.
If you are Daniela, or someone like her, read the MCS handbook carefully. Document your mentoring history. The candidates you supported, when, at what level, what you helped them work on. That documentation is what the Credit for Prior Learning path evaluates. It is not automatic, but it is a real pathway.
What to do right now
If you are a PCC or MCC who intends to keep mentoring credential candidates after January 1, 2027, here is where I would start.
First, read the MCS handbook end to end. It is on coachingfederation.org under the Credentialing section. It is not a short document, but it is the actual source. Do not rely on Facebook summaries, including this one.
Second, figure out which path fits you. If you have been doing informal mentoring for years and have candidates who can vouch for it, the Credit for Prior Learning path might save you 41 hours of new training. If you have not, the Standard Path is probably faster than trying to reconstruct evidence from memory.
Third, if you go the Standard Path, start looking at MCS-aligned training programs now. The 41 hours has to align with the ICF Mentor Coaching Competencies specifically. Not every mentor coach training program will qualify. Ask directly whether the program's curriculum is designed to meet the MCS requirements.
Fourth, if you already have a mentee in progress, decide whether to complete the engagement before the January 1, 2027 cutoff or transition them to an MCS-holder. The hours you deliver before that date still count under the old rules. Hours you deliver after that date only count if you hold the MCS.
Fifth, do not wait. The application takes time. The Standard Path takes months of training. If you want to be mentoring credential candidates in 2027, the work starts now.
Why this matters for the profession
I want to end with something that took me a while to appreciate.
The old mentor coaching model asked mentors to hold two roles at once. Support the candidate through the process. Also evaluate whether they are ready. Those are different jobs. A lot of mentor coaches, especially the ones who were also the candidate's training school instructor, felt pulled between them.
The MCS does not resolve that tension entirely, but it does say clearly what the job is. You are the person who holds the standard. You calibrate. You give feedback the candidate can use. When the ACC and PCC Portfolio performance evaluation goes away in April 2027, you are the person who says whether the candidate is ready.
That is a real credential. It should be earned.
If you want to keep doing this work, the path is open. If you have already been doing this work, the Credit for Prior Learning path is worth reading before you spend 41 hours on new training you may not need.
I am cheering for the mentor coaches. This profession does not work without you.
