Sorry OP. Sucks to see our kids disappointed, even if part of life. A bit late, but if your whole team was moving up, I would have asked the coach if he/she could use a waiver on your son. If he said yes, I wouldn't have even told my son that he didn't make it. At this point, agree with PPs advice. Also, tell your son that the assessors only had an hour to observe everyone and so maybe didn't get a real sense of what you're capable of. Also, if he's into professional sports, you could give examples of players who were cut when they played youth sports. For my generation, I always heard how Michael Jordan was cut from his high school team. Good luck.
