Look in the upper left corner of the report. Important parts of the report will include an entry for the number of questions or the total number of questions on that particular part of the test; the national percentile, the percentage rank of your child's score relative to other children who took the test; and the grade equivalent, the average grade of children who would have matched your child's grade on the test.
Examine the upper right corner of the report. This part reflects banded cores, the range of scores that your child could reasonably be expected to score if she retook the test.
Look at the bottom part of the report, which usually will contain either a narrative or content cluster summary of your child's performance in each test. The content cluster, if used, will show the number of questions on the test, the number answered correctly, the number that your child answered and didn't leave blank, and a box checked for "below average," "average" or "above average performance."
