Maybe I am use to hearing a lot of the stories around here but the wait until fall is a very common approach. They (districts in our area) usually test during the first month and make their recommendations at that point. Also do to the reading and ABCs part they might not be willing to jump him a grade but rather offer a pull out option. But back to the wait til the fall equation ... a lot can happen in regards to reading and ABCs by the fall.
I agree with inky ... first step is to test him. It will give you a starting point and facts to back you up b/c schools are quick to make assumptions without it.
