My daughter missed the cutoff by a couple of weeks but we early-tested her into Kindergarten and, although she's one of the youngest in her class, she is doing great, both academically and socially. She now goes to Happy Valley charter school in the Northwest Valley and we love it there. They have a very advanced curriculum and bunch kids in classes according to their academic level. I know they just started having a Kindergarten class for kids in the September - December birthday group (the ones who normally miss the cutoff for the year). They do fill up very early though. You might be able to find a similar program at a charter school in your area. Good Luck!
