Hoagies Gifted that's your first stop for browsing. What else you need will depend on what your concerns are, if any. You don't have to fix anything that isn't broken, and although we tend to spend most of our time talking about problems here, for obvious reasons, there are children with scores like your DD who don't need any intervention. It's great that she is happy, obviously. You probably should also ask yourself whether she's happily learning things at school, or being bored but having the disposition to cope with it without it making her miserable. If the former, congrats, you don't have a problem, although you should keep watching in case underchallenge becomes a problem later. If the latter, you may have a difficult situation as you'll have to weigh the importance to her development of learning to deal with challenges against the undesirability of rocking a boat in which she's happy. One option there is to make sure she has an extracurricular challenge of some kind - music, a language, whatever she's interested in.
