I took the DAT at the Glastonbury CT testing center. I would recommend this place to take the DAT because the staff was super friendly, it was CLEAN (area, lockers, your cubicle, monitor, mouse), and it was a test-like atmosphere. Umm, even though there were maybe five or six other people there taking tests, it did not bother me. The staff would come and walk around periodically, but that didn't bother me either.
