Sorry, I can't help with specific schools, but I found that our parochial pre-k school was the best bet for early entrance. They knew DD and her abilities better than any other school and our public flat out refused early entrance. Did your current school do the testing and what are their concerns about early entrance? What specific testing has your son done so far? Maybe getting a formal IQ and achievement testing done (if you haven't yet) would convince the school to do a trial in K and your son is likely to do just fine.
