We are in talks with the school for DS5, who is to start kindy next year. My hope is that he will be able to do things with the kindergartners in areas where his skill is age level (handwriting, fun stuff), but that he'll get to go to other grades for reading/math. Kindergarten itself will be a huge shock for DS in terms of how long it is, and I know they have more breaks/fun stuff than in 1st, so I really can't imagine him going straight to 1st. And DS is pretty little compared to his agemates. But we're doing WJ-III with the school next week, and then they'll have all the info they want so they can come up with a plan.

It sounds like most of the successful kindy-skippers here have been girls; perhaps they're ready to sit down and be good a bit earlier than boys? Obviously it depends on the kid, but the girls in DS's preschool sure seem to cooperate a bit better.
