Wow, those are great scores! Maybe this was mentioned already - in addition to acceleration you probably want to consider asking for compression - not sure I'm getting that term right. Bascially the idea that you can put your ds in 7th grade math (or whatever level) and then proceed at the same pace as other 7th graders going forward doesn't make much sense. He'll probably need things speeded up - fewer repetitions, covering more in the same time as a regular 7th grade class. I think this is a major benefit of homeschooling. We don't hs and I am very jealous of that aspect, but at least our ps does 'talk' about compression!
Good luck and welcome
