My son just graduated Kindergarten last week and I did have a full time aide written into his IEP. In my case, we were fortunate that the school district didn't argue, but I made sure ahead of time that I was very prepared. He did not need the aide for anything academic, but I was very concerned about the playground, getting to and from school activities and PE. Although it was not part of her job description, during the times that he didn't need her assistance or watchful eye, the aide worked with other children in the class and assisted the teacher with class projects, etc. My son NEVER knew that she was there to help him and for me it created peace of mind knowing that there was someone there to help and watch out for him.
