Oddly, DD preferred testing in a group setting!! When she took the ACT there wasn't time to apply for accommodations, and she wound up doing slightly better on all the sections except writing. Go figure, right??
We just didn't tell anyone, and because they didn't know her at the testing site, it was fine. Nobody questioned it, and the proctor was fine with her having her meds UNDER her seat, and not in the pile of everyone else's junk at the side of the room. (We didn't want her epipens there since there was likely nut residue on at least some coats, backpacks, etc.)
