First, I'm very sorry you're having this problem. I totally agree your kid should be able to get what they need from school.
However, you seem to be somewhat informed about this issue, so I am wondering whether you have considered the alternative approach (or whether it is practical for you) of homeschooling/ afterschooling, etc. This has worked so far for our family and our DD9, with patched-together school attendance (meaning she was kicked out of two schools so far), and she is also accelerated in math (doing EPGY algebra for the past year, which is not too fast
) and IMO on the spectrum somewhere but on the very edge of being 'normal' at least by past standards--so has social issues but IMO not much else; we're still trying to figure that out but are pretty sure. Anyway, from mostly lurking on this site (which has been amazingly helpful), it seems like you can sometimes get a reluctant school to do what it should, but if you have the resources (mostly time and money) to DIY that seems more likely to have the desired results for your kid. We are going to have to re-integrate into the school system soon because I don't feel at all qualified to teach all the various high school subjects and plus both DH and I have outside jobs, but I am really wondering how that is going to work out. But in the meantime we have been working with afterschool programs (EPGY, IMACS) and so far it has been good.
So again, sorry you're having this trouble and I hope the school comes through for you, but I just wanted to mention these other possibilities in case you haven't considered them. Best of luck!
