Keep in mind that the MAP has a standard test error that runs approximately +/- 3 points. When kids get somewhere in the neighborhood of the high 220s, maybe low 230s, on their reading test that test error also matches their expected growth for the year. At that level, I tell parents that MAP is very helpful for knowing what a student is ready to learn and is less helpful about showing actual growth.
I would push teachers to see how they're using the data. I routinely used MAP to teach upper elementary kids allegory, allusion, extended metaphors, etc that just aren't in the curriculum for kids that young.
