Interesting question. I'd have to think that since SAT's measure achievement, they'd consider the grade the child is in, as the sliding scale presupposes a difference in what the child has been exposed to. Once you're accelerated, you're accelerated, right? On the other hand, I seem to recall that the WIAT type tests can be scored using either the child's grade or age (as our psych pointed out the difference in DS's report last year). I guess that's the difference in the differrent types of tests.
