I don’t disagree, and that’s the thing about the laws here - the law promises that disabled students will be provided with the resources needed to fully participate in schools. It does not specify what resources will be provided, because those resources will be different in different situations.

A student may be given a sign-language interpreter for live lecture classes, and then when the class watchs a movie, maybe closed-captioning is sufficient. If the class normally uses oral exams, maybe deaf students will be given a written exam instead as an accommodation.
