Christel: My son has an IEP and was retained in 3rd grade without my consent or any meeting. It has almost been two years since the retention. Do I have to file a due process hearing to get this revoked? I was unaware of all of the negative outcomes of holding a student back, and at the time I had so many other issues with the school that I did not proceed with filling a complaint against the school concerning this matter. What can I do?
