Most rating sites would stop at “76% proficient” and call it done. Twin Rivers Charter deserves a closer read. The school sits in Yuba City, where one in three students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

The headline number: 53.5% of students scored in the top band on the state test. The California average is 21.3%.

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

Frequently asked questions

Is Twin Rivers Charter a good elementary school?
Twin Rivers Charter has a Scope Score of 71 out of 100, placing it in the 92nd percentile of California elementary schools and ranked #479 statewide. 53.5% of students exceeded the state standard on the 2025 CAASPP assessment, which is 32.2 percentage points above the California average of 21.3%. The Scope Score weights six dimensions for elementary schools: exceeded standard (43%), met or exceeded (22%), grade 3-to-5 growth (15%), chronic absenteeism (10%), ELPAC English Learner proficiency (5%), and suspension rate (5%). Data source: California Department of Education CAASPP 2025, analyzed by SchoolScope.
What are Twin Rivers Charter's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 75.7% of students at Twin Rivers Charter met or exceeded the state standard in ELA and Math combined, and 53.5% exceeded it. The gap between those numbers matters: 22.2% of students are at the proficiency floor, while 53.5% 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. 320 student-subject combinations were assessed.
How does Twin Rivers Charter rank in California?
Twin Rivers Charter ranks #479 among California elementary schools by Scope Score, placing it in the 92nd 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 Twin Rivers Charter getting better or worse?
Based on 2025 CAASPP data, proficiency at Twin Rivers Charter decreases by 0.2 percentage points from Grade 3 to grade 5 growth. This downward pattern doesn't necessarily mean the school is failing — it can reflect cohort differences, demographic shifts, or curriculum changes. A campus visit and conversation with teachers can reveal what the numbers can't. Growth trajectory is weighted at 15% in the elementary Scope Score because it measures what the school does, not just who walks in the door.
What is the attendance and school culture like at Twin Rivers Charter?
3.8% of students at Twin Rivers Charter are chronically absent (missing 10% or more of school days), which is better than the California average of 17.9%. The suspension rate is 1.9%, indicating a low-discipline-incident environment. SchoolScope includes these culture metrics in the Scope Score because they reflect day-to-day school experience in ways test scores alone cannot.
How does Twin Rivers Charter compare to other schools in Yuba City?
Twin Rivers Charter scores 71/100 (92nd percentile) among California elementary schools. To compare with nearby schools, SchoolScope shows the same metrics side by side: exceeded rate, proficiency, growth trajectory, and school culture indicators. The school serves 519 students.
