I couldn't understand: AE: 8-3, Easy to DIFF 7-10 8-10, RPI: 100/90, PR: >99.9%.
What does that mean? 7yr old-10 yr old? 8 yrs old - 10 yrs old?
What does RPI 100/90 mean?
AE stands for "age equivalency" or something like that, so she performed on par with a typical 8yr 3month old child. I believe that the DIFF 7-10 8-10 means something about the range in which her score falls accounting for a margin of error. Her "true" score could be as low as that of a 7yr 10month old to as high as a 8yr 10month old child. I'm not sure on the RPI #.
