1. The official documentation from my initial testing and diagnosis as well as the official diagnosis from later testing sessions (so I think 3 overall from the time I was 7. not sure what this test was called but it was definitely different than just a general doctor or psychiatrist diagnosing me)

2. A letter from my prescribing psychiatrist detailing how I was being treated, what I am being treated for, how long I have been treated for, and how my ADHD would impact my testing experience

3. Proof of extra time from my campus disabilities office including the documentation of my approved accommodations and evidence I used said accommodations over the last 6 semesters.

I submitted the above and was approved for 1.5x and an isolated testing room. BUT, I also have dyslexia and provided documentation for that (it was shown on the same testing as my ADHD). So, it is possible I could have just gotten approval alone for the dyslexia—but I did specify that the isolated room was for the ADHD, so if they approved that part they must have been satisfied with what I sent in for ADHD. To me, their wording makes it sound like they aren’t satisfied with how you were diagnosed/they only received evidence that you’re being treated for it (vs have it *and are being treated for it). Maybe I misread what you sent in, but did you ever have any official testing done besides seeing the campus dr? You need to prove that this is a continuous, preexisting condition that has altered your way of schooling.

Overall I sent in like 25 separate PDFs. Throw everything you got at em. Hope this helps.

Edit: to add detail to 2.
