Measures test performance, attendance, and climate — not arts, community, or your kid. How we score →
Most rating sites would stop at “52% proficient” and call it done. Sierra deserves a closer read. The school sits in Manteca, where more than half of students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
The headline number: 64.9% of low-income students met the ELA standard — versus 38.2% for the same group statewide.

How does Sierra High rank in California?
Sierra High ranks #585 among California high schools by Scope Score, placing it in the 66th percentile. This ranking is based on a weighted composite of 2025 CAASPP test performance (exceeded and met rates), chronic absenteeism, and suspension rate. Unlike single-number ratings, the Scope Score shows what drives the ranking so parents can decide what matters most to their family. See full methodology.
