Having taught autistic children in private schools around Toulouse, may I suggest you seriously consider your move to France. There are schools and institutions that accept children with autism however as well as your child having to deal with a new language you may find the treatment quite barbaric and attitudes positively medieval especially if you have come from outside of the continent.Many french professionals still see autism as an illness or brought on by over protective mothers. It was only last month educational authorites agreed that wrapping autistic children tightly in cold wet sheets, was no longer considered an effective form of treatment.
Some institutions are more receptive and enlightened than others however the final decision to accept a child with autism into the state eductional system rests with its classroom teacher, therefore this decision may change from year to year. I have only known of one autistic child to have stayed in France.The other parents have all left feeling that their children's needs could be met much better elsewhere. Speaking frankly, if it were my child, I would not move to France.
