We have gone through two years of preschool and could put him into private kindergarten at the age of five, or wait until he is six. He is a very tall and big kid, I don't want the other kids to make fun of him. I think there are pros and cons. Please give me some advice.
Your son may be ready for kindergarten and just sail through school even though he misses the cut-off date. Readiness for kindergarten is not an exact science. It depends on the child's physical, social, intellectual, and emotional development. Nevertheless, solid research shows that chronologically older children do better in kindergarten and the primary grades and are less likely to fail a grade or be classified as learning disabled. There is no agreement on how long the effects of youngness last. Some believe it diminishes as grade level increases and disappears by third or fourth grade.
You need to think beyond the start of school when your child may be the largest student in his class. Will size or age be more important when he enters high school or even college? Will he be able to handle social situations with his older classmates? Here's another factor to consider. If you enroll your child in a private kindergarten because the public schools will not accept him, when will he be able to enroll in public school? Many public schools will not accept young transfer students in first grade.
