My daughter is on the autism spectrum and spends a portion of her day in a special day class. However, due to the efforts of the teachers at LAUSD's Kennedy High School, she has several opportunities for mainstreaming including ROTC and choir. In this video, she had the opportunity to sing the National Anthem with a general education peer prior to a basketball game. This is what mainstreaming should look like.
I wrote about this program in this article.
