GreatSchools Ratings for California
In calculating these ratings, GreatSchools analyzed the 2011-2012 California Standards Test (CST) English language arts, math, and science results and compared them to the CST results for all California schools with the same grade levels. Note that GreatSchools' ratings differ from California's Academic Performance Index (API) rankings.

If there are no GreatSchools Ratings for a school, the school's test results were either not reported or incomplete. The different student groups are identified by the California Department of Education. If there are fewer than 10 students in a particular group in a school, the state doesn't report test results for that group.

Keep in mind that when comparing schools using GreatSchools Ratings, it's important to factor in other information, including the quality of each school's teachers, the school culture, special programs, etc.

GreatSchools Ratings cannot be compared across states, because of differences in the states' standardized testing programs.
