I have to disagree- our feeling has been that it is better to go to the public school if your child has a disability/something that can be addressed by an IEP. Private schools DO NOT have to offer the same services to you. It's just that simple. You can try to get the IEP set up there, but they don't have to do it.
Private schools also may have less experience, despite what they say, at taking care of children with disabilities. The public schools HAVE to deal with that- per the ADA laws.
My son is very bright and hearing impaired. We went through 2 private schools and finally came to our (excellent) public school, which has been fantastic for the hearing loss.
HTH.
