Here they would not let DS skip INTO Kindergarten, but they let him skip OVER it into first grade, so he had two years of preschool and then first grade.

I wouldn't worry about missing out on the experience of Kindergarten--but then, I myself didn't go to anything before first grade! They didn't have preschool back then, and my mom said I already knew anything that they might teach in Kindergarten, so she didn't send me. I don't think it scarred me for life or anything.

Good luck!
