Something like EPGY also gives you access to above-grade work. It's a lot easier to show the school what a child is capable of if they're given access to harder work than it is if they only ever get to see material that's at-grade level. In the latter case, I think you tend to get a lot more nit-picky nonsense like a friend of mine got: the teacher came to the meeting with a (very small) pile containing every assignment he'd had in the previous months that contained any error--very few, in this child's case, and mostly of the "misplaced comma" sort of mistakes. The teacher's argument seemed to be "See, he's not perfect! Therefore he's not GT." <eye roll> (As the mom correctly noted, "If that's all the mistakes he'd made, and they were that insignificant, I think her pile supports my case better than hers!") :p
A child who has access to and excels at work that's above-grade level can sidestep a lot of this sort of nonsense.
