I just wanted to chime in that has not been our experience. 260/250 are definitely not the upper limits on the Math/Reading MAP 2-5. We have seen higher scores many times. In fact, DS has never scored below 260 on the Math MAP 2-5 but has scored substantially above that.
I will say though it may be difficult to break the 250 barrier on the Reading MAP 2-5 due to unfamiliarity with technical literary terms or formal literary analysis techniques. I think that DS was able to score above 250 on the Reading MAP only because he has an extensive vocabulary and is extremely strong in non-fiction reading.
