You are right, I wasn't including learning disabilities. The university has had students with learning disabilities taking online courses. I was referring to students with visual, auditory or physical issues that need W3C accessible courses. I've been out of the loop for several years and learning disabilities may now be included in those standards. Of course, some accessibility tools such as page readers apply to LD students.
My favourite high school LD story is a student who had a scribe for exams but wasn't allowed to use the scribe for computer-based exams because all the students had to be in the same computer room at the same time and talking wasn't allowed.
