You might want to contact your school board and ask them if they can do a inservice teaching session. They can invite professionals in to teach the teachers about autism, behavioral and teaching stratagies. Maybe do it on a supt. conference day? So you can reach the masses.
You really might get your voice out there if you do it a school board meeting. It would be hard to for them deny the need in front of the whole audience.
Really want it bad....organize it yourself....how could they say "no." Ask them for a date and time and make calls advocating the need for autism awareness in your district. I find that most professionals or any person that has great knowledge of autism has someone near and dear to them that has it. They probably have had the same issues you have had. Appeal to their humanity.
The only way we are going to get help for our kids is to fight for them.Be your child's advocate!!!!! Be their voice!!! Go get them girl!!!!
Good luck! I wish you all the best.
