Measures test performance, attendance, and climate — not arts, community, or your kid. How we score →
Most rating sites would stop at “30% proficient” and call it done. Excelsior Charter School Corona-Norco deserves a closer read. The school sits in Corona, 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: 12.8% chronic absenteeism — versus 30.2% statewide. Attendance is the quietest strong signal a school can post.
As a charter, Excelsior Charter School Corona-Norco enrolls by application, not address — the score reads the same, the enrollment path doesn't.
