Dude, were I in your shoes, I really would get a lawyer and send the principal and district superintendent a letter that shows how they are out of compliance with state law. Your DD deserves better than she is getting. These problems can be solved.
We have had some rocky times with our public school in the past, but we are on track for the best year ever for DS10. They are showing a huge commitment to making the scheduling and content challenges of DS's education work well. His math (subject-accelerated) is more appropriate than it's ever been, and he's happy with it. There are signs that he's going to get individualized and meaningful science education ths year, which means a serious investment on the part of the school, initiated by them. He is placed with a teacher who is equipped to deal with all his interesting and unusual needs. I have the feeling that this public school is really, truly making a heroic effort for my kid.
That's why I know it's possible.
