Being said friend of Jbgmom above, yes, I am very happy with my daughter's placement. But please know that it would be prudent to hire an advocate to get the best services, no matter where you move to. And it may come down to hiring a lawyer, but I wouldn't necessarily go that route to begin with. Once you decide where you're moving to, get involved with local support groups as quickly as you can. They will probably be your best source for deciding exactly which school system would be the best fit for you. You'll probably find that many people won't want to share their particular school district over the internet because it's there for everyone to see and they'll be afraid that their school district could be inundated with special needs kids and the costs that come with them. But, in a support group meeting, people are much more open.
We were happy with the public school initially. But our daughter's behavior became more severe and we knew she needed an outplacement. Here in CT, there are MANY state-approved special education schools. Please be sure to visit the ones you think might work before deciding you want your child to go there. They are not equal, by any means. Here is the link for the list for CT:

The other thing you need to keep in mind is that, where there are better services, the cost of living will almost definitely be higher.
