Which CAT was used? My DD's old school used the Scantron Performance Series, which tested out of grade level. DD ended up about 4 grade levels ahead on scoring for both reading and math. On testing days, she would come home with her eyes glazed over because it really forced her brain to work harder. (You should not worry about the number of items she missed. The adaptive process makes the questions harder with each corret answer until the program gets to a level where the student misses questions. You should receive a printout with a summary of the testing, a raw score, and/or a percentile rank. Once the student stalls out on the testing, the computer will begin the testing at that level the next time around.)
