What an interesting story. Thanks for sharing it. Years ago my deaf daughter was also diagnosed as autistic, by people who were “observing” her. The whole write up by the teacher was contradictory. I had to go to Gallaudet and speak with a professor there, and found a specialist near my home then (So CA) who had worked with mentally disabled or criminally insane deaf individuals to get this “diagnoses” refuted.
I'm so glad you were able to get solid refutation, and by a credentialed and respected expert. There were either none such entities in the SF Bay Area; or any willing to fight the state on my behalf. No sooner, had I won the first battle for my son, when the state went after my other children. It was one loooong, nightmarish battle after another. They began the practice, legally, of teachers as "facilitators". Pulling my kids out of class asking them if I abused them at home, had guns in the home, what kinds of foods did I have in the home.
And this, in the geographic locale-central of "Say No To War". ha.
