My difficult child is not gifted (just a gift) but he is a smart kid when he doesn't allow his moods to interfere.
His standardized testing and his grades made him eligible for the IB program in our city school system (which in our district is offered only at one middle school) next year for middle school. While it was quite an honor to be asked to attend, it never was an option for difficult child.
I know, that while he is a smart little boy, the stress and anxiety of being in a highly competitive academic enviornment would not be a good fit for my son.
I think you need to look at each case individually and look hard at the needs and temprament of your child.
