Measures test performance, attendance, and climate — not arts, community, or your kid. How we score →
Most rating sites would stop at “48% proficient” and call it done. Centennial deserves a closer read. The school sits in Corona, where four in five students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
The headline number: 60.9% of low-income students met the ELA standard — versus 38.2% for the same group statewide.
