Hey, guys, let's be careful not to fall into unhelpful stereotypes of ADD. My husband has ADD, is very high functioning, takes medication and is not scattered. He is in a high management postion in corporate finance.
My DH has a PhD and is incredibly successful in his job too. I apologize for overgeneralizing.
I am sure there are people with ADD who could handle a K class, but the thought of my DH in a K class was very scary and it does have
everything to do with his ADD! He is really great with children one-on-one, but even fully medicated, he does not do well when interrupted. Every interruption or distraction creates a startle reflex that increases each time he is interrupted. This would not be pretty in the case of 20-30 children who are learning to behave!
By the way, your comment about "highly focused and detail oriented" is true of my DH as well. It is one of the true positive aspects of ADD and a feature that is commonly overlooked. But the problem for my DH is that when he is in that highly focused state, it is almost physically painful for him to transition out of it. It is also hard for him to find the middle ground of lightly or moderately focused. It's the lightly and moderately focused state that is ideal for teaching--constantly scanning for problems and prepared to change gears at any moment. This is also very different than the chaos of unfocus in which things are changing gears without a clear reason.
