Coastal Grove Charter: The score is middle of the pack. The trajectory isn't.
Coastal Grove Charter sits mid-pack on raw proficiency — and it's climbing faster than most schools anywhere near it — and that holds when you follow the same students across grades.
Coastal Grove Charter scores 47 of 100 on SchoolScope's Scope Score — the 66th percentile of 5,744 California elementary schools (CDE CAASPP 2025).
Measures test performance, attendance, and climate — not arts, community, or your kid. How we score →
Most rating sites would stop at “44% proficient” and call it done. Coastal Grove Charter deserves a closer read. The school sits in Arcata, where three in five students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
The headline number: +15.2pp separates this year's grade 3 from its grade 5. The state average rises 4.5pp over the same span. Following the same students from 2023 G3 → 2025 G5 points the same way.
As a charter, Coastal Grove Charter enrolls by application, not address — the score reads the same, the enrollment path doesn't.
