I had the same problem with my child last year. It was her first year in preschool and I was so excited to watch her progress but unfortunately she made none. she would have melt downs and the school even though they claimed to be a school for children on the spectrum asked me what to do. I changed schools and now she is doing much better. I am proud to say she has made most of her goals. You may want to change schools. I dont know if you do or not but I have learned in order to get your child the treatment they deserve you need to be loud. unfortunately schools will take advantage and pay most attention to the children who's parents know what it available to them and make the most noise.

IEPs should be monitored every 4.5 weeks. If your child received more than one not progressing or emerging skill the IEP should be evaluated and goals/objectives should be changed to meet-able goals. With that being said if you feel his goals are meet-able but he is not being given the proper instruction or accommodations which would allow him to meet those goals you should meet and add accommodations to ensure he gets what he needs. I understand schools busting at the seems our school went from 3 children on the spectrum to 40 children on the spectrum in just 1 years time. We are a very small school and I've got to say despite the stress of all the new kids we have learned how to accommodate everyone. It is an ever changing battle.
