I just got my CSP from https://www.scrumalliance.org/, so this topic is fresh in my mind. I’m excited as it is another phase in my Agile / Scrum journey. What I find interesting is the number people with CSM’s and other equivalent Scrum Master level don’t go to local Agile community events. I’m really disappointed in a number of “agile” companies in downtown Wilmington that don’t have like a minimum of 20 Scrum Master attend their local agile networking events. Most don’t charge

To get my CSP I had to earn 70 SEUs to apply, so it was a great excuse to go out, attend and learn so much from smart people. Know I’m one of those sick people that love to learn, so I go anyway. Professional Certs that require one to get involved are I think are the best. I know the dreaded PMI organization does this also, but it does help people stay up on new ideas or even rekindle old ones.
Now that I have my CSP, I have to stay engaged to retain it. It is not like you take a test and you are certified forever.
I guess if I was to interview someone I would ask two questions (1) what was the last Agile or Scrum event you went to (here I know if you are a CSP or a PMI-ACP you had to do something) and (2) Did you apply anything you may have learned to a scrum team?
If you really want to get me all active ask me about qualifications on being a real Project Manager or Program Manager. I have done that to, but I also worked in just about every functional area there is over my career. However, I love the Agile Dynamic.
