I think a lot of the good academic resources have been well covered, so I will not repeat them. I will say, we did run into a "hitch" if you will around the end of 3rd grade in which peers and sports played a larger role than I would have anticipated. As much as he wanted to continue to be extremely accelerated, he also wanted to be in class and play sports with peers. I will spare you the multi-year saga, but I would examine the personality of your child and determine whether he is a kid who is happily "defined by" engaging in academics alone or if he is into sports, peers, art etc. as well. This may play a role in how you continue to accelerate and decide whether to go "broader" or "deeper" in his academics.
