I just want to chime in to say our ADHD-acting DD5 was tested and, in a quiet, focussed testing room without any other stimuli, and with lots of interesting, challenging tests to take, has laser focus. And we are laughed out of the testing office. When she went to the jungle-gym-looking, primary colored, fun house that was the occupational therapist's testing environment, she went berserk and took nearly three one hour sessions to be able to focus on a test that normally takes (other kids with sensory processing disorders) one hour to complete. I have no answers for you, just wanted to sympathize with regard to testing. :-/
