My son is in a GT program, 4th grade. He is scoring in the high 250s on the MAP-M with only a half year acceleration (all that is available even at GT). End of third grade was similar score.

I read on another thread that ideally kids should be taught at the 90% score for a grade, so this would be 8th grade if I am interpreting correctly. How much stock should we be putting in these scores? He also scored very well on the SCAT math test 97% percent for two grades up while in second grade.
