Concerning certifications. For the most part it was started to help the sport and educate its own. Not as a means to be exclusive but inclusive. The sport is such a great one that the players out paced the coaches.
Sometimes it is used to assist in a coaches resume, a standard that he can be measured by a perspective employer.
Some are overly concerned with the paper because it is something they can see. Someones abilities are not easily seen or understood.
I guess its like a drivers license. I have one and so did the butt head who cut me off the other day.
