It is my understanding that IDEA is a federal law and that the school has to provide your child the minimum education free of cost. It should also include transportation (as it does for our state KS). Secondly, your principal (unless a competent doctor) cannot undiagnose your child to pacify other parents. I had to go to our school unannounced to ensure that my child was receiving her services that are written in the IEP. We were deliberately lied to and found that she was not receiving the services and that the teacher did not want her in the classroom. You need to know what you and your childs rights are and get to know the education system that is how you can help your child the best. To become the advocate that no one else can do as well as you.

I know that the best way to get the teacher to follow the IEP is to get her a copy and highlight the things that she needs to do. I spend as much time in the classroom as possible and I do stop by unannounced to see his IEP team and talk to them about their last visit with my son and what they accomplished. It is a lot of work but if I am not babysitting my IEP team they will stop doing what the accommodation's that are listed in the IEP. I transferred my son to a new teacher because his other teacher kept saying he does not have any problems. If there are no problems then she does not have to do any more work. Switching teachers has helped my son a lot. He was feeling very anxious about going to school with the other teacher because she was to negative and loud. His new teacher is softer spoken and far more organized. He is much less anxious.

I have a soon to be 21 year old son, diagnosed with Asperger in 5th grade. If I could have afforded it and lived in New York, there is a school just for the Aspies.
We had a HORRID time in the public school system. My son was bullied every day in highschool.
First of all, a principal can not legally 'un-diagnose' anything. The IEP's are generally not followed unless you are constantly on top of it. It was exhausting trying to get him through school.
The main issue is lack of education on the part of the teachers! Because Asperger/PDD, NOS is not a physical deformity, most people simply think the child is just disobedient!!
Public school was terrible for us. I wish I had some helpful information for you, but just keep advocating for your child. If you can afford a specialized school, DO IT!! We couldn't, unfortunately.
I wish you the best of luck.

Wow, thanks slot. i have tried to find things before but I guess didnt know what to search for because I didnt find these at all. Thanks a bunch!!

Do you have any organizations or people who could advocate for your son, as a second person? In Utah, we have parent advocates at the Utah Parent Center who will attend an IEP to help you for free. If you don't have something like this available, does he have any therapists or "professionals" who can help you work with the school? I agree with TerriN above, that you need to push the issue if they are not following the IEP. Sometimes individual teachers vary in how well they do with a particular child and how well they follow the IEP, but the special ed coordinator should be helping with that issue, so I would bring it to their attention. Approach the District if you need to, especially if the principal is not supportive. Good luck! That is frustrating. I work with kids every day who have been pushed out the door and know they don't feel welcome at school. It is by some miracle they are still trying when they hit the high school I work for, and we are so fortunate to have an awesome special ed coordinator who advocates for them and understands the laws.
