🤝 Culture First · Solid
ranked #1,311 statewide · #3 of 34 in Lodi Unified
Rio Valley Charter scores 56 of 100 on SchoolScope's Scope Score — the 77th 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 “43% proficient” and call it done. Rio Valley Charter deserves a closer read. The school sits in Lodi, where three in five students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
The headline number: +1.6pp 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, Rio Valley Charter enrolls by application, not address — the score reads the same, the enrollment path doesn't.

What are Rio Valley Charter's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 43.0% of students at Rio Valley Charter met or exceeded the state standard in ELA and Math combined, and 15.3% exceeded it. The gap between those numbers matters: 27.7% of students are at the proficiency floor, while 15.3% 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. 235 student-subject combinations were assessed.
How does Rio Valley Charter rank in California?
Rio Valley Charter ranks #1,311 among California elementary schools by Scope Score, placing it in the 77th 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 Rio Valley Charter getting better or worse?
Based on 2025 CAASPP data, proficiency at Rio Valley Charter increases by 1.6 percentage points from Grade 3 to grade 5 growth.
