I dont know about the player profiling system,, I do know that GPS has a curriculum that they follow. The coaches (at least the paid coaches) have staff development on it weekly. Im not sure about the coaches who arent full-time employees,,, I would assume they have something though. As for evals,,, they have a evaluation template they use,,, it may be hit or miss though.. As one son received an evaluation and the other did not. My friends at CBSC have been impressed with what they have seen so far,, so that sounds like good stuff coming from them.
