Thanks for the responses--

the private school would only be for kindergarten, then to first grade the following yr (district said this could be done)

socially, I think he's fine--gravitates to older kids anyway. BUT, there is still some maturity issues (basically, he acts like a four yr old boy at times--in other words, a big goof ball! But over the next several months, this may no longer be an issue.

His dexterity (fine motor skills) not so great; it was recommended to get him assessed to see if he qualifies for OT through the school district (not sure how bad it is either.)
