map rit scale link?

I recall reading that MAP scores are some how less reliably valid way out in the last percentiles.

For those who are confused, or comparing a third grader's MAP scores with 10th or 11th grade RIT mean, etc.:

RIT scores are not meant to be compared across grade levels. RIT scores are a measure of the *level of item difficulty* that a student can handle compared to *others in the same norm group*. A third grader, irrespective of however well she does, will not be seeing the questions asked of a 10th grader. (Yes, the RIT scores have the same "meaning", the meaning being, "level of item difficulty a student can handle compared to others in the same norm group.")

Yeah, they really do not make it clear that you can't compare a 3rd grader and an 11th graders scores. It just gets very muddled up in everything they say. They say that a 2nd grander and an 11th grader with the same score are correctly answering questions "of the same level of difficulty" but then that means the 2nd grader is doing very difficult arithmetic and the 11th grader is doing very difficult algebra/statistics, etc. I think the easiest way to think of it is that there are 3-4 separate tests and you can probably compare within those tests, but not across them. This explains why we see a drop in scores at the beginning of 3rd grade. Because now instead of taking the K-2 test, they're taking the 2-5 test, and effectively being compared with 4th and 5th graders rather than K and 1st graders. They should just say, there are 3 different tests and you can only compare your score with the norms for kids who take the same version. And they should not put them all in one chart.

Really? In one of these links, there is an explicit example that uses scores of a 2nd grader and a 7th grader to describe why they should NOT be compared !!
