To emphasize what others have said, don’t fixate too much on particular schools or camps just yet.
I do think it might be helpful to attend a camp or two now, to get a better idea of what to expect if he wants to go down the recruiting road later. From that perspective, it might be better to go to a camp that is not at any likely top-choice schools — for practice.
One of the best things he can practice at this point is learning good communication skills with the coaches: eye contact, handshakes, more than one-word answers, ready with questions and thank-yous at the end of each session.
