## Types of Scores Reported

Stanford 9
For each school, district, county and for the state, the following types of scores are reported by grade level and content area:

• NPR (national percentile rank) of the "average" student estimates the individual percentile rank of a hypothetical "average" student in this group.
• % (percent of students) scoring above the 75th NPR shows the percent of students in the group scoring in the top quarter nationally.
• % (percent of students) scoring at or above the 50th NPR shows the percent of students in the group scoring in the top half nationally.
• % (percent of students) scoring above the 25th NPR shows the percent of students in the group scoring in the top three-quarters nationally.
• Mean Scaled Score estimates the group average scaled score for each grade level.
California Content Standards (STAR Augmentation)
Average Number Correct out of Total Number Possible: The group scores reported for the California Content Standards are "raw scores" that are the average number correct out of the total number of items possible. The total number of items is the sum of the items created specifically for the California Content Standards plus selected items from the Stanford 9. For English/language arts the totals consist of 35 California Content Standards items plus 40 selected Stanford 9 items at grades two and three and 55 selected Stanford 9 items at grades four through eleven. For mathematics, 15 items from the Stanford 9 were identified as standards-based at grades two through seven and added to the 50 customized California standards-based items, for a total of 65 items.

At grades 8 through 10, 15 items at each level designated as appropriate to that grade level were selected from the Stanford 9 to be combined with the 50 customized California standards-based items. Thus the total number of items possible on the mathematics tests at grades 8 through 10 is also 65--15 Stanford 9 items plus the 50 customized California standards-based items. Students taking the algebra I California Content Standards test at grade 9, however, would not take any Stanford 9 items identified as contributing to the total score because the Stanford 9 items selected for use at grade 9 were chosen as foundation skills for geometry, not for algebra. No total score can be calculated for students who did not take both grade level components that contribute to the total score. While no augmentation scores will be reported at grades eight through ten for students tested with other than the test designated for that grade level, the number of students taking the test and the percent of enrollment are reported.

SABE/2
For each school, district, county and for the state, the following types of scores are reported by grade level and content area:

RPR (reference percentile rank) of the "average" student estimates the individual percentile rank of a hypothetical "average" student in this group.

• % (percent of students) scoring above the 75th RP shows the percent of students in the group scoring in the top quarter of the reference group.
• % (percent of students) scoring at or above the 50th RP shows the percent of students in the group scoring in the top half of the reference group.
• % (percent of students) scoring above the 25th RP shows the percent of students in the group scoring in the top three-quarters of the reference group.
• Mean Scaled Score estimates the group average scaled score for each grade level.
