I can't see anything against him taking the AMC10 if he wants? There doesn't seem to be any rules of how many times you can take the test, you just have to be at most a 10th grade student. I am sure practice helps at taking tests like this.

What about the AMC8? (What is his grade level?) Has he done that already? I assume he is looking at the AMC10 because he already has algebra & geometry behind him? (OK.. I just re-read your message.. he has already done the ACM10.. for get this.)

I would take it on a case by case basis. I guess the trick is you don't want him to burn out or get discouraged if he tries them too early. But if he is excited and willing and doesn't get in the way of other activities I see nothing wrong with letting him participate. I would just make sure he knows before going in that he is competing against much older students.
