I don't think I could be more certified. I've taken the course and the test for the Positive Coaching Alliance, the Coaching for Character course and book, plenty of regular clinics that discussed these issues, PAV and CPR certification that all school coaches must have, etc, etc., etc.
Having said all of that, I'm pretty leery of ethics classes being mandated or any necessary certification beyond basic first aid and CPR. The overwhelming majority of the stuff is pure common sense and anyone dumb enough to need a class to learn it is going to be too dumb to gain anything from the class. Further, not much is worse than listening to the ethics police preach about how the entire (coaching, legal, medical, etc.) field is unethical and "we must do better or our profession is headed for disaster."
