I downloaded the 2008 Normative Data. It only has means and medians but not standard deviations. That's why I was looking at the other information that had RIT blocks for grade.

Based on the 2008 Normative Data her RIT score puts her around 3rd grade middle of the year median and mean for reading. It puts her around 2nd grade middle of the year median and mean for math. This makes sense with the work we've seen her doing.

I'm going to ask to talk to the school MAP testing expert on Monday because I think the percentiles were for a different grade.
