We were checked for ACE Certification at ASA/USA-A and at the Eastern A last year, background check ID's as well. Valley Extreme asked for it last year as well.
For a first time coach, ACE isn't too bad if you actually listened to it. I think all beginner coaches could actually get something from all of the videos but since they can be found on youtube and it appears to be money grab the process won't ever get a fair shake.
