Thank you Indigo, for helping me clarify my concerns/pros and cons and for the helpful links.

I do have to say I can't see DS in a middle school for anything. He is a rather small 7 year old, only 45 pounds, and with no awareness of his surroundings. I think he would get trampled and not even notice it happening! The middle school is also a distance from the elementary school, so it would involve bussing and missing extra class time. I can't see it being a feasible option right now.

As far as his two friends go, they are both in K and will stay in the K-1 classroom for 1st grade next year. They will be in class together again the following year in the 2-3 class. The whole class was only 5 kids this year (later 6) and there was only one other boy in 1st grade and he and DS really clashed. The 2 girls are both the type who have no interest in a very adhd kid like my DS (quiet and studious types). But maybe some of the current 2nd graders or some new students would appeal to DS as friends next year? Right now the class size is looking like 6 again per 2/3 classroom, so out of 12 kids hopefully they group them so that DS is in with a likely friend.

As far as DYS application goes, I have been considering it, but I'm a little hesitant to send in the entire 36 page evaluation report including all of DS's medical information. I did ask the school psych if she would be able to type up a report with just the cognitive and academic testing for the purposes of applying to special programs and she said she will need to ask if that is permitted and get back to us. Otherwise I guess I just send in the book of DS? It says no pages can be missing, but can I ask them to only look at the relevant pages?
