Bullis Charter scores 97 of 100 on SchoolScope's Scope Score — the 99th 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 “96% proficient” and call it done. Bullis Charter deserves a closer read. It sits at the 99th percentile of 5,744 California elementary schools — but the ranking is the least interesting thing on this page.
The headline number: 84.1% of students scored in the top band on the state test. The California average is 21.3%.
As a charter, Bullis Charter enrolls by application, not address — the score reads the same, the enrollment path doesn't.

Frequently asked questions
Is Bullis Charter a good elementary school?
Bullis Charter has a Scope Score of 97 out of 100, placing it in the 99th percentile of California elementary schools and ranked #2 statewide. 84.1% of students exceeded the state standard on the 2025 CAASPP assessment, which is 62.8 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 Bullis Charter's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 96.1% of students at Bullis Charter met or exceeded the state standard in ELA and Math combined, and 84.1% exceeded it. The gap between those numbers matters: 12.0% of students are at the proficiency floor, while 84.1% 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. 768 student-subject combinations were assessed.
How does Bullis Charter rank in California?
Bullis Charter ranks #2 among California elementary schools by Scope Score, placing it in the 99th 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 Bullis Charter getting better or worse?
Based on 2025 CAASPP data, proficiency at Bullis Charter increases by 1.4 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 Bullis Charter?
4.2% of students at Bullis 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 0.4%, 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 Bullis Charter compare to other schools in Los Altos?
Bullis Charter scores 97/100 (99th 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 997 students.

Subgroup data is context, not part of the Scope Score: we don't penalize schools for who they serve. See our equity approach.
