Highly gifted at that age, I'd think it is time for a serious life goal discussion. He should be of a mind to discuss what things drive him, what he enjoys learning. What sort of experiences he wants. When in school has he been excited to go, etc. As well as planning on how he can take control of turning thngs around, asking himself why he ats as he does. Are there other avenues/approaches to get the same positive results without the negative. Also, might be a good time to find a semi-academic summer camp that will let him stretch and explore his capabilities like robotics or game programming, etc.
