CDE CAASPP 2025

Most rating sites would stop at “53% proficient” and call it done. Six Rivers Charter deserves a closer read. The school sits in Arcata, where one in four students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

As a charter, Six Rivers Charter enrolls by application, not address — the score reads the same, the enrollment path doesn't.
