Blatantly obvious for my 7yo. He's reading Dickens, taking Arabic and doing pre-algebra. He doesn't blend. :p
It might depend on levels of GTness here, since MG and closer to ND might manage to fit better, especially if they're GT in one subject and not across the board and get most of their intellectual stimulation at home instead of at school. They might slip past teachers unnoticed, sadly.
But I doubt HG+ kids are going to slow down.
I think how much challenge they get in school is a biggie, too. If GT kids are working at grade level between K and 3rd grade, yes, they might "level out" a bit because the GT kids really haven't learned much of anything for 4 years, while the ND kids have! That's hardly the kind of leveling out that I think is intended, however!
