Scores are SchoolScope's analysis of public data, not official CDE ratings. They represent one way of interpreting test results and should not be the sole basis for school decisions.
Numbers tell you whether students are clearing the bar. A school visit tells you whether they're happy doing it. These metrics are intentionally missing from the Scope Score: class sizes and student-teacher interaction quality; arts, music, athletics, and enrichment programs; teacher experience and turnover; campus safety and social-emotional support; parent and community engagement; quality of special education and gifted programs; how resources are distributed across schools within the district.
