Thanks everybody for your thoughts.
Regarding accommodations, I don't think private/public would make much difference. In our public system, if your child has an LD you can get a "code" that allows certain accommodations. For example, my DS7 (dyspraxia/dysgraphia) has a "motor impairment" code that allows him things like extra time, a scribe, a computer, time with a specialist, etc. There isn't a code for ADHD, and I haven't pursued getting any accommodations for DS11; I don't think I'd get too far with the school since he is an above average student without any extra help. Of course, this might change next year when the organizational expectations will be much higher . . .
Aculady, you make a good point about the stress level. DS is somewhat anxious and I think being able to walk to school is a real advantage. He won't be rushing for the bus after school, and hopefully would have time to get the books he needs out of his locker. He could also eat at home -- he doesn't like eating at school (and doesn't eat much lunch most days) because its crowded and smells like other people's lunches. His stress level would also be lower because he would know lots of other kids from the outset.
I did a bit more research and found out that the IB program is the certificate, not the diploma, program. So the intense writing, etc of the last two years won't be an issue.
I would say that right now I am leaning towards the IB public program. However, my DH is still strongly in the private school camp. The private school is clearly more rigorous academically. DH thinks that we shouldn't let DS decide as he doesn't have the life experience or perspective to make this kind of choice. I understand this point of view, but my DS is *very* stubborn and opinionated, and I think forcing him to go to a school he doesn't want to go to could backfire.
nmmom -- no I wouldn't call my DS very introspective. However, I do think he is aware of what situations he feels comfortable in, and he seems to think strongly that the private school atmosphere is not for him. I think the IB program is a bit reminiscent of the Montessori school he went to for 7 years.
He could switch from one of these programs to another after a year, although I'd like to get it right the first time. His biggest issues are social, so changing schools wouldn't be ideal.
