Mia-
My now-adult son had TERRIBLE fine motor skills when he entered school. He was instantly put on an OT plan, and had PT as well. I really cannot imagine your son's writing being worse. My son was still advanced a grade for math and reading (yeah, big whoop for a PG kid, but we were so ignorant!) and he really did not have any trouble keeping up with the amount of writing needed in lower elementary. IF the school tries to make it an issue, ask them if an "age appropriate" first or second grader would be held back for poor handwriting. I'll bet not- they'd just do their best to accommodate and support.
