GreatSchools Rating

The GreatSchools rating is a simple tool for parents to compare schools based on test scores. It compares schools across the state, where the highest rated schools in the state are designated as “Above Average” and the lowest “Below Average.” It is designed to be a starting point to help parents make baseline comparisons. We always advise parents to visit the school and consider other information on school performance and programs, as well as consider their child's and family's needs as part of the school selection process.

About the test

In 2014-2015 California tested students using the California Assessment of Student Performance and Progress (CAASPP), administered through the online Smarter Balanced Summative Assessments. These are comprehensive, end-of-year assessments of grade-level learning that measure progress toward college and career readiness. Each test, English language arts/literacy (ELA) and mathematics is comprised of two parts: (1) a computer adaptive test and (2) a performance task; administered within a 12-week window beginning at 66 percent of the instructional year for grades three through eight, or within in a 7-week window beginning at 80 percent of the instructional year for grade eleven.

The summative assessments are aligned with the Common Core State Standards (CCSS) for ELA and mathematics. The tests capitalize on the strengths of computer adaptive testing—efficient and precise measurement across the full range of achievement and timely turnaround of results.
