CORE Charter scores 39 of 100 on SchoolScope's Scope Score — the 47th 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 “27% proficient” and call it done. CORE Charter deserves a closer read. The school sits in Marysville, where more than half of students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

The headline number: 5.7% chronic absenteeism — versus 17.9% statewide. Attendance is the quietest strong signal a school can post.

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

Frequently asked questions

Is CORE Charter a good elementary school?
CORE Charter has a Scope Score of 39 out of 100, placing it in the 47th percentile of California elementary schools and ranked #3,031 statewide. 8.5% of students exceeded the state standard on the 2025 CAASPP assessment, which is 12.8 percentage points below 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 CORE Charter's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 27.3% of students at CORE Charter met or exceeded the state standard in ELA and Math combined, and 8.5% exceeded it. The gap between those numbers matters: 18.8% of students are at the proficiency floor, while 8.5% 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. 206 student-subject combinations were assessed.
How does CORE Charter rank in California?
CORE Charter ranks #3,031 among California elementary schools by Scope Score, placing it in the 47th 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 CORE Charter getting better or worse?
Based on 2025 CAASPP data, proficiency at CORE Charter increases by 15.5 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. 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 CORE Charter?
5.7% of students at CORE 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 0.7%, 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 CORE Charter compare to other schools in Marysville?
CORE Charter scores 39/100 (47th 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 554 students. Use the schools in Marysville page or the map view to compare all elementary schools nearby.
How does CORE Charter serve low-income and underrepresented students?
At CORE Charter in Marysville, 46.2% of low-income students met or exceeded the ELA standard in 2025 and 38.2% statewide. Other subgroups: Low-Income students (18.9% Math proficient); White students (48.0% ELA proficient). The largest proficiency gap is 4.4 percentage points for low-income students. Data source: California Department of Education, CAASPP 2024-25. 143 students tested. SchoolScope shows disaggregated test scores by demographic subgroup so you can see how a school performs for your child's specific group — not just the school-wide average. Subgroup data is context, not part of the Scope Score: we don't penalize schools for who they serve. See our equity approach.
