ITA with mnmom23's post (as well as the other posts above). I also find it helpful to respond to comments such as "we have several children who are (whatever)" with "I'm not here to talk about the other children, I am here to discuss my ds' needs."
The other thing I'll add - you've been advocating for subject acceleration etc at this school for quite awhile and seem to continually run up against brick walls. When this happens it's possible that changing up your advocacy approach could help, but it's also possible you've hit THE brick wall and the school isn't going to flex no matter how you approach advocacy. When we were in the situation you are in now, we eventually switched schools - and after making that switch I *really* wished I'd spent less time trying to make the first school work. I don't know if that's the point you're truly at yet, but if you are feeling like you are spending tons of effort advocating and getting nowhere, that's a sign that maybe it's time to look into alternative school options.
Best wishes,
