Group B is "professional development", not "community service". My personal take is that to the extent that the HOA experience is the former, yes it could count. As you start your HOA journey it likely will teach you leadership strategies, conflict resolution, and team building, all of which I likely would submit because they would easily apply to a professional setting. As things start to get "routine" and my involvement became more about "serving" and less about "learning", I personally would cease claiming CPEs.
Of course, I am just your peer. An official verdict would come from the Auditors and/or Member Services.
