River Valley Charter scores 81 of 100 on SchoolScope's Scope Score — the 99th percentile of 2,160 California high schools (CDE CAASPP 2025).
Measures test performance, attendance, and climate — not arts, community, or your kid. How we score →
Most rating sites would stop at “76% proficient” and call it done. River Valley Charter deserves a closer read. It sits at the 99th percentile of 2,160 California high schools — but the ranking is the least interesting thing on this page.
The headline number: 48.6% of students scored in the top band on the state test. The California average is 15.8%.
As a charter, River Valley Charter enrolls by application, not address — the score reads the same, the enrollment path doesn't.
