One of the reasons I was so hesitant about a grade skip with my own DC is consistent with momoffour above. I graduated from high school at 16 and left for college. While I was fine academically (university honors program etc) I was not ready in many ways. As a middle aged woman I still can't help but feel like I missed out on some experiences because I was a few years younger than my peers. I simply was not ready to deal with some of the social stuff. Academics are not the only thing that matters and sometimes dealing with peers that are having sex, drinking etc when you are much younger than them can put pressure on a child that they are simply not ready for. Also, how are you going to structure rules? Will your child have freedoms that are consistent with their age or that of their peers? It can get tricky:).
