I disagree with teachers publicly sharing scores (in most cases), but every kid in our district knows that your score flashes up on the screen at the end of your MAP test. Can't really hide the score from the kid. DD10 tells me her score after she tests - you don't need to wait until the scores come home.
Kids also know what percentile scores are needed for the advanced classes, so they pretty much know which kids did well on the MAP tests.
The only times I recall scores being shared with the whole class are when kids did really well (as in a perfect score on a national contest).
