The diagnosis of a student wouldn't matter to me. My job is to teach the class and their job is to figure out how to negotiate their situation with the help of the accommodations office. I have to let them have whatever the law says they get -but other than that - I believe a large part is them figuring out what they have to do to get the job done - not me figuring out their particular diagnosis. I rarely even know what my students are diagnosed with and I really don't want them telling me even though some do tell me anyway.
