Internal Coach Certification

Democratize Coaching through creating your organizational Internal Coaching Hub!


  • Practical capacity building coaching tools for coaching within ever-changing organisations.    
  • In-house executive coaching skills accelerating a culture of coaching.    
  • Coaching services with a high Return on Investment.
  • Empowered internal coaches with ΙCF accredited ACSTH learning and an all weather coaching kit. 
  • A growing impact of HR.    
  • A-Z Internal Coaching Framework to integrate internal coaching within the organisation.


Conceived and designed with the HR and/or Transformation leader in mind, this program envisions to deliver a state of the art coaching certification program that will address the full spectrum of coaching competencies, equip participants with in depth coaching skills as well as practical tools designed and tested to work within organisations. 

As Internal Coaching, we define a coaching process supported by the organisation and provided by internal coaches who are members of the same organisation and are trained in professional coaching.  Internal coaches undertake coaching assignments with coachees/clients within the same organisation, yet outside their own line management responsibilities.

Internal Coaching is amongst the most powerful interventions to build a coaching culture, to support transformation and agility of organisations.

The program is currently accredited as ACSTH program by the ICF and as of 2023 it is transitioning to cover the LEVEL 1 ICF requirements.


You will be able to coach with a  pragmatic and brief coaching methodology, the Solution Focus which is particularly fit for the business environment.

You will  learn how to use tested, practical coaching  tools tailored to leadership and performance  based on our experience of implementing coaching within organisations.

You will be able to design and manage an A-Z coaching assignment as you will be equipped with a full coaching KIT. Everything from the Coaching forms, to the detailed process steps, all the key factors to anticipate in communicating the program internally and educating the involved stakeholders (prospective coachees, coachees' bosses, top management).

As a coach you will feel empowered with a Solution Focused coaching mindset, your clients will get high ROI from a professional coaching service, and HR will grow its impact through supporting capacity building and transformation through coaching leaders through it.

Should you decide to work as an external coach, you will be even more equipped to handle executive coaching assignments as internal coaching is amongst the most complex forms of coaching offerings.

  • It is designed for experienced HR and other leaders who wish to undertake an Internal Coach role together with their existing tasks and have a strong interest in people development.

What do participants say about this course?

Maria Nikolakaki - ONLINE Internal Coach Certification Participant
Video Testimonial

"... in the past I was expert in solving problems, now I am an expert in finding solutions"

Maria Koniakou - ONLINE Internal Coach Certification Participant - Video Testimonial

"On a practical level, my colleagues and my manager noticed that I have changed the way I handle communications both orally and written. I am now focusing on what has worked and on strengths and I was told that this helps people "unlock" ..."

Using solution focus methodology helps you to delve deeper into a person's issue and shows the path for improvement/change without making any reference to the problem itself at all. As a coach you need to focus on the person's strengths & achievements, trigger the proper questions and the solution is there coming straight away from the coachee himself/herself it's amazing!

Our coaching methodology is based on the Solution Focus. The approach values practicality and is especially suited for working with leaders within organisations. The focus is on working with people strengths through defining the what is wanted, discovering the what is working and what contributed to that and on making practical progress. It leads to a positive and pragmatic way to work within organisations and beyond coaching it is helping instill a new culture of addressing people at their resources.

How do you define Internal Coaching?

An Internal Coach is an employee within an organisation who has been trained and qualified as a professional coach practitioner and has specific coaching responsibilities with colleagues outside own line of management responsibilities.

How much time would I need to invest to meet requirements of this program?

The program spans within a 6 month period and it has a 90 hour duration. Therefore, you could estimate an average of 15 -20 hours per month. Of course this varies according to each individual.

How can you tell whether coaching has been an investment worthwhile?

This is a very good question that is relevant not only for coaching but for most Leadership Development programs as well. Business Impact and measuring ROI is a core area of our own research about coaching and and as such we have incorporated in our ACSTH "Internal Coach Certification" program a simple yet effective methodology to calculate ROI of your internal coaching assignments.

Does ACSTH accredited training means I am an ICF credentialed coach?

ACSTH training stands for Accredited Coach Specific Training Hours and it is a term used by ICF to signify that a specific program has been assessed to meet all operational and quality standards to cover training requirements for credentialing via the ACSTH option. Minimum ACSTH for ACC credentialing are 60 hours and the Atom Wave "Internal Coach Certification" program is a 90 hour program with 70 ACSTH hours, so the 60 hours are more than covered. Additionally, in order to get credentialed as a coach at ACC level by the ICF, you would also need to:

  • 4 Hours of Mentor Coaching (within the program you get 6 mentoring hours and therefore only need 4 instead of 10)
  • Submit a Recorded Session & Transcript which will be assessed 
  • 100 client coaching hrs (not with Direct reports)
  • Pass the Coach Knowledge Assessment
  • Pay the respective application fee
