Rio Vista High scores 52 of 100 on SchoolScope's Scope Score — the 57th percentile of 1,739 California high schools (CDE CAASPP 2025).

Most rating sites would stop at “25% proficient” and call it done. Rio Vista deserves a closer read. The school sits in Rio Vista, where two-thirds of students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
The headline number: 77.1% of students leave measurably college-ready, versus 35.5% statewide.
