You've had a lot of great advice (if you ignore Squads;-). I would wholeheartedly concur that the way forward is not to punish and seem disappointed but to support and find out why. Some kids do indeed grow so weary of school that they simply won't go ( didn't happen to us because ours were home educated), in which case wild horses won't drag them there. there are many alternative from home schooling to college to simply realissing that your son is not in a place where he will accept any more education at this point. that does not mean that he will be an underachiever, wastrel, drop out etc, it just means that he's at a very difficult time in his life for a boy and that he's feeling overwhelmed at the moment. Cut him some slack, get talking to him, don't rule out him being bullied or depressed or stressed just because it's not obvious and above all don't worry and panic, it's not the end of the world, just a temporary setback if handled right.
