Gifted Issues Discussion homepage Forums Identification, Testing & Assessment Ceiling effect on NWEA MAP math section?

I agree that your DD has not reached the ceiling yet. Even for grade 2-5 test, I heard a kid got 290 at the end of 4th grade. My 4th grader got 284 during the spring test. Also the district office told me that it is very common to drop when switching from 2-5 to 6+ test based on all the data they have seen.

You need to be exposed to new and more advanced concepts if you want to keep the score growing. Your DD's 3rd grade score was very impressive. For 6+ test, I know that several kids got over 300 and one kid just run out of all the questions in the test bank.

NWEA themselves acknowledge MAP RIT scores in reading cap out around 245 even if the scale goes up to 300. I think I read on this site that MAP Math goes up to 320 and ceiling kicks in at 260.

"A ceiling effect exists when an assessment does not have sufficient range to accurately measure students at the highest performance levels. It has nothing to do with the actual numbers attached to the scale and everything to do with the position of students on it. For example, in reading, the RIT scale measures with relative accuracy up to about 245. This represents the 93rd percentile at grade 10, and the 95th percentile at grade 8." https://legacysupport.nwea.org/support/article/532

Not sure what alternatives exist, http://www.scholastic.com/education/assessment/literacy/sri-index.htm and they have one for math too.

EDIT: OK wait this may be the answer, the MAP 6+

So my question now is, does the "MAP 6+" still have a ceiling effect, and at what RIT score. I don't think NWEA is responsive to questions from parents, only from teachers.
