Thanks so much to this forum - we have learned so much! Most importantly - ask questions ahead of time!
We brought my son to one camp and found out that day he would receive only a verbal evaluation, unless, of course, we spent more money. At another camp which listed many schools being "represented", we saw only a few people evaluating players. We thought that "represented" meant that the coaches/asst coaches would be there - they were not. Supposedly scouts for those schools were there but we have no way to confirm that. We are still hoping to receive at least a written evaluation. We should have contacted the schools we were interested in to confirm they would be at this camp or at least have a legitimate representative.
Though the camps didn't meet our expectations, my son had a good work out at both, got a sense of how these camps/showcases work (long days!), and saw how his skills compared to others his age who are also looking to play baseball in college. And we parents now know to do a better job doing our homework on camps before spending the money!
