Wow! I don't know if Martha is being serious or trying to be funny.
Anyway, my aspie daughter did go through a perfectionist phase back when she was 4. It's hard to tell from the limited amount you wrote about, but my aspie radar did NOT go up based on what you wrote.
The teacher feels he's fine. My question to you is, are these behaviors new or not? If they're new, it could be something situational. Is his school, or the teacher, pushing for perfection from the kids? Is your son having insecurity issues for some reason? Have you tried talking to your son about why he's getting so frustrated? One other person mentioned how gifted kids feel this type of pressure to be perfect. That may be the issue too,
I feel it never hurts to get a child assessed if you feel like something is going on. However, if these behaviors are totally new, then I think you might want to pursue other issues first.
I know NOTHING about ADD/ADHD, but I hear that some kids really need to be medicated. Those are pretty extreme cases though. I think some people have had great success with doing lots of sports activities, for example. Finding a problem doesn't necessarily mean the child has to be medicated. So far, my daughter doesn't need anything at all!
Good luck!
