Well, if you look at a bell curve it should really just be a no brainer, right? The middle 40% or 50 %so, in the average +/- 10 IQ range, correctly placed with a "grade level" (ie average) curriculum. About 25% to 30%on each side of the curve, give or take a few, a year up or down from "grade level". (Sorry about the passive aggressive quotation marks, can't help myself). And a few percentage points on each side who could do with a curriculum 2 or more years further out, if not necessarily with the acceleration or demotion into a higher or lower age group.
You'd think it's a no brainer, but of course one could frame it into a scandal JUST being uncovered. Wait, they could write a book about it and call it, umm...a nation deceived or something? Like it might really get educators' and politicians' attention?
