Of course, I see the boys in the evening when the short acting drug has worn off. All of their teachers have commented that they tend to pay attention and focus better. The dramatic drop in GPA in the 4th grade may coincide with the switch from verbal to written instruction and response. They responded well to verbal, highly interactive teaching environments. They don't do so well when the teacher tells them to turn to page 15 and work problems 1-25.
Fourth grade is also the time in which teachers refuse to take late assignments.
I am working in technical service. The most obvious ADHD child I've met is the son of an obviously ADHD father. Amway seems to be a career path which doesn't require focus, and instead rewards those who can jump from task to task each time the phone rings. It is helping them cope with the public school system. I also wonder if a better education system might produce different results.
