Hmmm. Snowgirl, what grades are in your school? I wonder if they appropriately used the 2-5 and transitioned to the 6+ early. Or maybe the 2-5 does go up that high.
It definitely goes that high. My ds has always scored well above the cutoff for the 99th percentile, so that wasn't his first math MAP over 260. I actually heard that there's a much younger student in the school who scored higher (but still under 300). In other words, the test doesn't stop just because you hit the 99th percentile - it keeps going - which is one of the things I like about it.
Eta, I don't know what the ceiling is, but the 270-something score was when he was part-way thorough algebra 1.
