My son was reading by the age of 2 also. He was rather social as a little boy, but then became QUITE introverted. His needs were met the best in Cheyenne, Wyoming. There, they had a school (public – Pioneer Park was the name), that has a seperate section of the school JUST for gifted kids. He was in a class of 3rd graders who were ALL gifted, which meant that they ALL learned at a quicker pace. And ALOT of them had social issues (my son was academically brilliant, but socially, a bit behind). Being in a class with similar kids, meant that if he had a meltdown (and he did several times in his early elementary years), the other kids related to it, and did NOT pick on him. They were teaching the kids spanish in kindergaren, because the kids were SO EAGER to learn. We moved from there after 3 years (military move). To supplement his education, I bought workbooks from Sam’s Club (or find a teacher supply store… they are all over the place), and you can get your own things to work on over the summer, or to aid what the school system is NOT giving.
We have never found another school system that had a gifted program as young as kindergarten, except in Wyoming. Incidently, it was a wonderful place to raise a child! Everyone was friendly. Not much to do there (although they have expanded alot since we lived there 10 years ago). But the quality of life was so peaceful! It’s a little bit of a drive to an outlet mall, and a larger city.
All that said… we put our son in the gifted program when we got there, and saw the need. Honestly, until the 3rd grade or so… there really wasn’t much of a need, because we wanted him to learn the necessary social skills. We knew we could adequately supplement his education at home, until the academics got beyond workbook assistance. Hope this helps!

We’ve toyed with homeschooling the oldest because of boredom issues. When you’re kid isn’t even hiding the book she’s reading during class and the teacher just watches her do it because she still passes the tests, the school district isn’t really teaching her much.
