The camp is very good for inexperienced/new officials. In fact, I attended it my first two years of officiating and it gave me a very solid foundation (I was able to get a couple Varsity Games in my third year, which I accredit in some degree to the fundamentals I learned in this camp). It concentrates mainly on two man mechanics and fundamentals of officiating. However, he does touch on 3 whistle since this is the direction the game is going.
Steve Ellinger is top drawer and has a very good teaching approach. He is the Houston Chapter rules interpreter and serves as a rep on a State Board, although the capacity that he serves in escapes me right now. I have the utmost respect for Steve as I have also worked a few games with him and learned alot during those games.
It is run in conjunction with Willis Wilson's (Rice University- Head Basketball Coach) youth basketball camp. Therefore if you are looking for high end, athletic competition to call, it won't be found here. However, these lesser skilled youth players will test your rules knowledge and skills. If you can ref this level, you can ref anything

. Guest speakers usually include Willis Wilson, Local 5A Coaches (to give you a perspective of what the coaches look for) as well as D1 officials, who in some cases got their roots from Ellinger. Hope this helps, and good luck....
