Another thing that occurs to me is that the parents need to realise that just because their child counts as Gifted in the context of their small school, they're still very unlikely to end up ruling the country/winning a Nobel prize/earning a million a year. Many of them won't want to, and will be perfectly content with a non glamorous job. Many of these children will go on to university to find that everyone they meet was classed a Gifted at school, and that many of them are actually far more "gifted" than they are.

I don't mean that the parents should keep telling their child that their gifts aren't all that impressive, and keep on undermining their confidence. But I've read memoirs by people who were effortlessly top of their class in a tiny school, and were therefore encouraged to think that the world was theirs was their taking. Then they went to university and found that they ranked as pretty average, really, and it was such a terrible crushing blow to realise that they weren't actually the number 1 brain in the world that they never quite recovered.
