I really havent been keeping up with it all. I figured the NSCA will contact me if I need to take a National board test. I think it's a good idea, and from the people who I have talked to on the NSCA forums, they all do to. There's just way too many bad trainers out there, making a bad reputation to the Personal Training field.
Perhaps this new exam will weed out trainers who take an at-home test, pass, and then never due anything to continue educating themselves; just simply train people the way people trained in the 80's. (let alone having passed without neccessarily ever having seen a client!)
