Do I Need an MCS Mentor Coach for ACC Renewal in 2027?
Do I Need an MCS Mentor Coach for ACC Renewal in 2027?
Updated September 2026
If your ICF ACC credential is coming up for renewal in 2027, you may have started seeing a new acronym everywhere: MCS, or Mentor Coach Specialization.
And if you're wondering, Do I actually need an MCS mentor coach to renew my ACC in 2027? — the short answer is:
Yes, if you receive any new mentor coaching on or after January 1, 2027, your mentor coach must hold the appropriate ICF Mentor Coach Specialization (MCS).
But there are a few important nuances here, especially if you're starting your mentor coaching in 2026 or you've been hearing about new recording reviews, Session Observation Forms and Competency Review Forms.
Those changes are related — but they do not all apply to ACC renewal.
Here's what ACC coaches need to know.
What is changing for ACC renewal in 2027?
The biggest change is who is qualified to provide your mentor coaching.
Currently, an ACC renewal candidate can receive mentor coaching from an eligible ICF credential-holder at or above the appropriate level. An ACC mentor coach must have renewed their ACC at least once.
Beginning January 1, 2027, ICF is changing that requirement.
Any new mentor coaching completed on or after January 1, 2027 must be provided by a coach who holds an ICF Mentor Coach Specialization (MCS) at the level at which you are being mentored.
For someone renewing an ACC, that means you can work with an MCS-ACC and receive mentor coaching at the ACC level, or you can work with an MCS-PCC and receive mentor coaching at the PCC level.
So no — you don't necessarily need a PCC-level mentor coach simply because you're renewing an ACC.
You do need an appropriately specialized MCS mentor coach for mentor-coaching sessions received beginning January 1, 2027.
What is not changing about the ACC renewal mentor coaching requirement?
The basic structure of your mentor coaching stays the same.
ACC renewal still requires 10 hours of mentor coaching completed over at least three months, with a minimum of three hours of individual, one-to-one mentor coaching. The remaining seven hours can be individual or group mentor coaching, with ICF limiting mentor-coaching groups to no more than 10 participants.
And “three months” is worth paying attention to.
ICF's guidance specifies that 12 full weeks must pass between your first and final mentor-coaching sessions. This is one of the reasons I encourage ACC coaches not to leave mentor coaching until the month before their credential expires.
Your mentor coaching also needs to be about your coaching skills and your development in relation to the ICF Core Competencies. It isn't meant to become business coaching, marketing strategy, practice-building support or general life coaching. ICF describes mentor coaching as a process of receiving feedback based on observed coaching so you can refine your skills and develop greater alignment with the Core Competencies.
That part matters to me.
The goal isn't simply to collect 10 hours and check off another renewal requirement. Done well, mentor coaching gives you a structured opportunity to look closely at how you're actually coaching, identify patterns you may not be able to see yourself, and deliberately strengthen your practice.
What if I complete my mentor coaching in 2026 but renew my ACC in 2027?
This is probably the most important exception to understand.
You do not have to redo qualifying mentor coaching just because your ACC renewal happens in 2027.
ICF has explicitly confirmed that mentor coaching completed in 2026 or earlier under the current eligibility requirements can still be used toward an ACC renewal occurring in 2027 or later.
So, for example, if your ACC expires in March 2027 and you complete all 10 mentor-coaching hours with a currently eligible mentor coach before January 1, those hours can still count toward your 2027 renewal.
The important date is when you receive the mentor coaching, not simply the date you submit your renewal application.
If your mentor-coaching engagement will cross over into 2027, however, pay close attention to your mentor's qualifications. ICF states that mentor coaching received on or after January 1, 2027 must be provided by an appropriately specialized MCS mentor coach.
This is one reason it may be simpler to choose an MCS-qualified mentor coach now if your 10-hour engagement is likely to extend into 2027.
Do I need to submit coaching recordings to renew my ACC in 2027?
This is where much of the current confusion is coming from.
You may have heard that ICF is introducing a new process involving:
at least three observed coaching sessions, Session Observation Forms, a Competency Review Form, and a move away from the traditional Performance Evaluation process.
Those changes are real.
But they are primarily changes to the ACC and PCC credential application process — particularly the Portfolio pathway — not a new performance-evaluation requirement for ACC renewal.
ICF has stated specifically that ACC renewal candidates do not need to submit the MCS Session Observation Forms or Competency Review Form with their renewal application.
That distinction is important.
You still need your 10 hours of mentor coaching for ACC renewal.
Beginning January 1, 2027, those new mentor-coaching hours need to come from an eligible MCS mentor coach.
But you are not suddenly required to pass three recordings or submit a Competency Review Form to ICF simply because you are renewing your ACC.
So what's changing with recordings and the new ICF forms?
This is one of the biggest changes coming to ICF credentialing in 2027, and it's worth understanding even if you're currently focused on ACC renewal.
Historically, an ACC Portfolio applicant has submitted a coaching recording for a formal ICF Performance Evaluation. PCC Portfolio applicants have submitted two.
ICF is moving away from that model for ACC and PCC applications.
Instead of relying primarily on a final recorded performance evaluation, ICF is moving toward skill development and observation over time through enhanced mentor coaching.
Beginning January 1, 2027, ACC and PCC Portfolio applicants enter a transition period. Between January 1 and March 31, 2027, applicants can use either the existing Performance Evaluation route, submitting the required recording or recordings for assessment by ICF-trained assessors, or the new MCS Competency Review process.
Beginning April 1, 2027, the new process becomes required for ACC and PCC Portfolio applicants. The traditional ICF Performance Evaluation will no longer be available for those applications.
Under the new process, the coach works with an appropriately qualified MCS mentor coach who observes their coaching skills over the course of the mentor-coaching engagement.
ICF requires a minimum of three observed coaching sessions to inform that development and competency review. At the end of the engagement, the mentor coach completes a Competency Review Form documenting whether the coach has demonstrated proficiency in the relevant competencies.
For credential applicants using this pathway, the Competency Review Form is submitted to ICF. The individual Session Observation Forms associated with observed sessions are retained and may need to be provided if the credential application is selected for audit.
So when you hear someone say, “ICF is changing from one recording to three,” that's an oversimplification.
It's more accurate to say:
ICF is moving away from a single, end-stage ACC Performance Evaluation toward multiple observations across the mentor-coaching engagement, with a specialized mentor coach gathering evidence of the coach's development and competency over time.
Why is ICF changing the recording-review process?
This is one of the parts of the change I find particularly interesting as a mentor coach.
In my MCS training, we worked extensively with the new ICF Session Observation and Competency Review structure.
The philosophy is much more formative than a traditional one-and-done assessment.
Rather than listening to one “perfect” recording and asking whether a coach passes or fails, the mentor coach looks at coaching across multiple sessions, offers evidence-based feedback, helps the coach experiment and develop, and notices patterns over time.
The Session Observation Form captures what is happening within an individual observed coaching session.
The Competency Review Form takes a broader view across the mentor-coaching engagement.
In my training, we were encouraged not to wait until the final session to begin thinking about that cumulative review. The mentor coach is noticing development throughout the engagement: Where is the coach consistently demonstrating competency? Where is there growth? What patterns are emerging? And what still needs deliberate practice?
That's very different from treating mentor coaching as ten hours of conversation followed by one high-stakes recording at the end.
And although ACC renewal candidates aren't required to submit these forms to ICF, ICF explicitly says renewal candidates and their mentors may still choose to use them as tools for discussion and coaching-skill development.
I think that's an important distinction between what you have to submit and what can genuinely make the mentor-coaching experience valuable.
Does that mean recordings aren't important for ACC renewal?
Not at all.
A recording doesn't have to become an ICF submission in order to be useful.
Mentor coaching is designed around observed coaching. It's much easier for your mentor coach to give specific, evidence-based feedback when they're working with actual examples of you coaching rather than relying entirely on your description of how a session went.
That could mean reviewing a recorded coaching session together, examining a particular competency, noticing what happened at a specific moment, and then identifying something you want to experiment with in your next session.
One small but important technical detail: if your mentor coach listens to your recording outside your meeting and prepares feedback in advance, their private review and preparation time does not count toward your required 10 mentor-coaching hours. ICF only counts the interactive time spent in dialogue and feedback with your mentor coach.
For me, recording review is therefore less about “Can I produce a passing recording?” and more about, “What can this real piece of coaching show us about where my coaching is today — and where I want to take it next?”
Do I need an MCS-ACC or an MCS-PCC for my ACC renewal?
Either can work, depending on the level at which you want to be mentored.
Beginning January 1, 2027, ICF says an ACC candidate can receive ACC-level mentor coaching from an MCS-ACC or PCC-level mentor coaching from an MCS-PCC.
If your immediate goal is simply to strengthen your coaching at the ACC level and meet your ACC renewal requirement, ACC-level mentor coaching may be completely appropriate.
If you're already thinking about your eventual PCC and want your development to begin stretching toward PCC-level coaching, working with an MCS-PCC may make sense.
That doesn't mean mentor coaching should turn into an exercise in performing markers. The goal is still better coaching.
But your future credential plans are worth discussing when you choose your mentor coach.
What should I look for in an ACC renewal mentor coach for 2027?
First, make sure they're actually eligible to provide the hours you need.
Beginning January 1, 2027, that means verifying that they hold the appropriate ICF Mentor Coach Specialization. ICF has updated its Mentor Coach Registry to help coaches identify specialized mentor coaches.
Beyond the credential, I'd ask how they actually approach mentor coaching.
Will you work with real examples of your coaching?
Will you receive specific evidence-based feedback rather than vague advice?
Will you have opportunities to practice between sessions and return to areas you're developing?
Will the mentor coach help you understand the ICF competencies without turning every session into a test?
And does the relationship feel developmental rather than purely transactional?
Those questions matter because you're going to spend at least three months doing this work.
You might as well come out of it a stronger coach.
I'm renewing my ACC in 2027. When should I start?
Earlier than most coaches think.
Because the 10 required hours must span at least 12 full weeks, mentor coaching isn't something you can complete in a few intensive sessions right before your renewal deadline.
If your ACC expires in the first few months of 2027, starting in fall 2026 gives you much more breathing room.
And if your mentor coaching will continue beyond December 31, 2026, choosing an MCS-qualified mentor coach from the beginning can avoid having your eligibility requirements change partway through the engagement.
I've written more about this in When Should I Start My 10 Mentor Coaching Hours for ACC Renewal?, because timing is one of the most common — and most preventable — problems I see coaches encounter.
Need your 10 mentor coaching hours for ACC renewal?
I offer one-to-one ICF mentor coaching specifically for coaches renewing their ACC.
I'm an ICF Professional Certified Coach (PCC) and hold the ICF Mentor Coach Specialization at both the ACC and PCC levels. I also serve as a Mentor Coach at a coaching school. My approach combines the practical side of making sure you understand your renewal requirements with the part I care most about: using the process to actually strengthen your coaching.
We'll work with your real coaching, the ICF Core Competencies and specific feedback over time — without making the experience feel like ten hours of preparing for a test. You’re welcome to bring your “best” recordings…and your “messiest” - no judgement from me.
If your ACC renewal is coming up in 2027, you can learn more about my ACC Renewal Mentor Coaching program or book a consultation to talk through your timeline and what you still need.
And if you're not sure whether your existing mentor-coaching hours qualify under the 2027 rules, bring those dates with you. We can look at the timeline together.
