IEP for Aspergers

So this year at school, our son will have NO IEP for Aspergers. He is out of speech now, and his behavior is not severe enough at this point to qualify for an IEP. However, this makes me very nervous. Do any of you have IEP’s for your kiddos? How did you get the school to approve it? I requested an IEP evaluation last year and he qualified only on speech. Now he is out of speech, so the IEP has ended. They use something called the SIT program which still allows for interventions, but is not an official IEP.
