We do have some high school threads. I will try to link to them in a bit.
I guess I think that in high school those aren't basic accommodations anymore.
It's not that a child's need suddenly goes away in high school.
I bet the high school hasn't had to make many accommodations for FAs. My son was the first in his high school to have a 504 dor FA, and he just graduated. I know the school had more of them in the grades that came up after him.
