Discovery Charter scores 64 of 100 on SchoolScope's Scope Score — the 86th 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 “65% proficient” and call it done. Discovery Charter deserves a closer read. It sits at the 86th percentile of 5,744 California elementary schools — but the ranking is the least interesting thing on this page.
As a charter, Discovery Charter enrolls by application, not address — the score reads the same, the enrollment path doesn't.

Frequently asked questions
Is Discovery Charter a good elementary school?
Discovery Charter has a Scope Score of 64 out of 100, placing it in the 86th percentile of California elementary schools and ranked #805 statewide. 40.7% of students exceeded the state standard on the 2025 CAASPP assessment, which is 19.3 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 Discovery Charter's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 64.8% of students at Discovery Charter met or exceeded the state standard in ELA and Math combined, and 40.7% exceeded it. The gap between those numbers matters: 24.2% of students are at the proficiency floor, while 40.7% 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. 330 student-subject combinations were assessed.
How does Discovery Charter rank in California?
Discovery Charter ranks #805 among California elementary schools by Scope Score, placing it in the 86th 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 Discovery Charter getting better or worse?
Based on 2025 CAASPP data, proficiency at Discovery Charter decreases by 6.3 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 Discovery Charter?
10.8% of students at Discovery 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 1.0%, 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 Discovery Charter compare to other schools in San Jose?
Discovery Charter scores 64/100 (86th 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 555 students.

How does Discovery Charter serve low-income and underrepresented students?
At Discovery Charter in San Jose, 33.3% of low-income students met or exceeded the ELA standard in 2025, compared to 12.4% district-wide and 38.2% statewide.

Data source: California Department of Education, CAASPP 2024-25. 39 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.
