Hello Bobbie!  Thank you for asking this important question.  Please note that if you feel that services are not be conducted as outlined and agreed upon with your son's IEP then you can request another review meeting prior to his annual review.

There are steps to help you with this request.

First, make your request in writing.  Date the letter.  Make and keep a copy.

Second, It sounds that you are having a hard time "wading " through a lot of the  IEP process and could use some support. Call your school district and ask for the names of parent advocates.  If they don't have any then please contact your state level office for special education or a local chapter of an autism society.  Ask other parents too, if they have used parent advocates to help them decipher the complexities of the IEP process.

Third, write out specifically what you think is working and not working with your son's IEP.  Please bring two copies to the meeting.  One for you to keep in a file and the second to submit.  

I am including some helpful websites.  Of course, Education.com has many resources to assist you as well.

Good luck!
