I'm curious to know how your school uses the results.
Well, my school told me my oldest wasn't gifted because her beginning of 1st grade MAP results were less than 209 for reading and 211 for math.

Using the correct norms that's 91% 3rd grade reading and 95% 3rd grade math. After weeks of getting the run around, it turns out they were using bad normative data. When that was pointed out, they backed away saying MAP is not designed to determine placement in any sort of school program.
Our school based decision making council says MAP results are used as part of the school improvement plan for NCLB. I've attended the meetings but they've never discussed a meaningful report that includes means and standard deviations.
