My son has an IEP for his hearing impairment. I think that, in some cases, if your child is at grade level for the condition that the IEP is there for, the school could possibly remove the services being given for that. My understanding is that they don't have to give an IEP so your child is above grade level.
It doesn't mean obviously that your child doesn't have a disability but it might mean that the school doesn't have to provide services anymore.
