Bostonia Global scores 27 of 100 on SchoolScope's Scope Score — the 16th 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 “28% proficient” and call it done. Bostonia Global deserves a closer read. The school sits in El Cajon, where four in five students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
Test scores are one lens, and at this school they're a rough one right now. The sections below show the fuller picture — including the parts that are working.
As a charter, Bostonia Global enrolls by application, not address — the score reads the same, the enrollment path doesn't.

Frequently asked questions
Is Bostonia Global a good elementary school?
Bostonia Global has a Scope Score of 27 out of 100, placing it in the 16th percentile of California elementary schools and ranked #4,800 statewide. 10.5% of students exceeded the state standard on the 2025 CAASPP assessment, which is 10.8 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 Bostonia Global's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 27.9% of students at Bostonia Global met or exceeded the state standard in ELA and Math combined, and 10.5% exceeded it. The gap between those numbers matters: 17.3% of students are at the proficiency floor, while 10.5% 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. 563 student-subject combinations were assessed.
How does Bostonia Global rank in California?
Bostonia Global ranks #4,800 among California elementary schools by Scope Score, placing it in the 16th 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 Bostonia Global getting better or worse?
Based on 2025 CAASPP data, proficiency at Bostonia Global decreases by 13.2 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 Bostonia Global?
25.9% of students at Bostonia Global are chronically absent (missing 10% or more of school days), compared to the California average of 17.9%. The suspension rate is 2.4%. 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 Bostonia Global compare to other schools in El Cajon?
Bostonia Global scores 27/100 (16th 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 1,266 students.

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