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.

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.

Data source: California Department of Education CAASPP 2025, analyzed by SchoolScope.
What are Coastal Grove Charter's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 43.9% of students at Coastal Grove Charter met or exceeded the state standard in ELA and Math combined, and 18.9% exceeded it. The gap between those numbers matters: 25.0% of students are at the proficiency floor, while 18.9% pushed past it. Most rating sites report only the combined "proficient" number. SchoolScope surfaces the exceeded-vs-met split because it reveals whether a school's curriculum challenges students beyond minimum proficiency or paces toward it. 142 student-subject combinations were assessed.
How does Coastal Grove Charter rank in California?
Coastal Grove Charter ranks #1,965 among California elementary schools by Scope Score, placing it in the 66th percentile. This ranking is based on a weighted composite of 2025 CAASPP test performance (exceeded and met rates), grade-level growth (Grade 3 to grade 5 growth), chronic absenteeism, and suspension rate. Unlike single-number ratings, the Scope Score shows what drives the ranking so parents can decide what matters most to their family. See full methodology.
Is Coastal Grove Charter getting better or worse?
Based on 2025 CAASPP data, proficiency at Coastal Grove Charter increases by 15.2 percentage points from Grade 3 to grade 5 growth. This upward trajectory suggests the school is adding measurable value — students leave with higher proficiency rates than they entered with.
