That is the same link I have for the ceilings. My daughters math score did go down when she went from 2-5 to 6 plus this past year. I did not see a dip when either child went from primary to the 2-5 test.

According to the ceilings chart my rising 4th grader (2-5 MAP) is close to ceiling in math with a 255 and still a little wiggle room in reading with a 237 .
