Measures test performance, attendance, and climate — not arts, community, or your kid. How we score →
Most rating sites would stop at “61% proficient” and call it done. Connecting Waters Charter - East Bay deserves a closer read. The school sits in Union City, where one in four students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
The headline number: 2.7% chronic absenteeism — versus 17.9% statewide. Attendance is the quietest strong signal a school can post.
As a charter, Connecting Waters Charter - East Bay enrolls by application, not address — the score reads the same, the enrollment path doesn't.
