It is a great thing, and you don't have to be affiliated with the school system to get things going. My wife and I got the ball rolling in our county last year (neither of us are school employees). Kids started shooting this year, and one local middle school that we worked with won state, shattered the state record, and competed in KY for the National title (nerves got them, they didn't shoot nearly as well at KY as they had been at home, but did ok). This tiny school hadn't won a sports title since the 80's and had never won a state championship before.
Our club (traditional only) has become NASP friendly. We're figureing it out as we go, but hopefully we'll have more kids coming out to shoot with us since they will be allowed to use their NASP bows.
Good luck!
