I earned my CEC (Certified Enterprise Coach) certification with the Scrum Alliance in 2012. I’d applied in 2011, so it took me about a year to go through the process at the time. If my memory is right, I believe I was about the 43rd CEC at the time.
I did a search of CEC’s and CTC’s on May 26th and it showed 118 and 156 worldwide respectively. That’s ~300 coaches. The growth of CEC’s over an ~8-year period was ~10/year.
I had been serving in leadership and agile coaching roles for quite a few years prior to that. I’d also been part of a couple of fairly successful agile transformations at the organizational level. So, while I was confident in my coaching capabilities, I was excited to go through the process as a way of validating my journey, experiences, and skills.
Back then, the focus was on the breadth of your stances.
