The bottom line with preschool is that children go for the fun and socialization (which any kid can always benefit from). If they are advanced, just about everything they are learning comes from "homeschooling" anyhow. At this age, it doesn't necessarily mean that you have to go out and buy workbooks, but they'll get much more from us with playdough, cutting/pasting/painting/writing at home as they would in just about any 2-4 year old classroom.
This was pretty much our conclusion. He gets stuff at school he does not get at home.
Mr W (2y7m) will be moved to true Pre-K in a few days with 4 year olds, skipping the 3 year olds. He needed a transition time with his peers and now he is ready.
