I did homeschool Michael for 1 yr (he's my oldest with Asperger's) but he really missed the interaction with all of his friends from school, and he's the one that wanted to go back.
I'm just very pushy when it comes to his IEP and getting things set up for him the way he needs it to be.
Admittedly, he is very high functioning, and does not need a lot of special accomodations. He uses an alphasmart for typing (no-one can read his handwriting, it is on par with a 1st grader - but he can type faster than I can), and if he is feeling overwhelmed he can pull out his MP3 player to listen to music to soothe him, or if it is really bad - let the teacher know and he can go to the special ed office and there's a room that he can work quietly by himself in order to pull himself together.
The thing that has most frustrated him in the past has been bullying from other students - people assuming and teasing him about being "slow" or "something wrong" with him. The problem is he is strong - and he has no compunctions about punching somebody out if they insult him (NOT the way I want him to handle things!) But he has been in regular classes up until now.
I think being in the gifted classes will actually help out with this, because I remember from my school days, all of us in the gifted program stuck together. Yes, we might have been called the geeks by the other kids - but we didn't insult each other, and we didn't pick on kids that were less intelligent. Gifted kids for the most part are above bullying (there are always a few exceptions). So I think he will be much better off in the gifted classes this year all the way around. Plus it will move more at his rate.
