Is there an accepted rule of thumb, or something, for how much acceleration a child with a particular IQ might need, say, something like +1 grade level for 1 SD above the mean, +2 for 2 SD, +3 for 3 SD and so forth? I'm not talking about achievement as demonstrated on an achievement test, but where they fit comfortably in terms of actually doing the academic work (not necessarily in terms of classroom dynamics). I realize that children vary a lot, but still, there must some correlation to IQ.
Any ideas?
