Here's the document about transitioning from math MAP 2-5 to MAP 6+, which indicates 231 on math as a point to move up, if being exposed to higher level material. Our school did not do this early switch, and one DC was in the 250s and saw a sizable drop once on the 6+ (consistent with the spring to fall drop in the document below), which I found concerning in that they use 253 as a flag for taking the Iowa Algrebraic Readiness Assessment. You'd think they'd want a more stable score as a baseline. Our school did utilize the MAP results, in conjunction with other assessments, for acceleration decisions. I did not know you could input results into Khan, though, that's very good to know.
