Mission Preparatory scores 49 of 100 on SchoolScope's Scope Score — the 64th 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 “49% proficient” and call it done. Mission Preparatory deserves a closer read. The school sits in San Francisco, where four in five students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

Mission Preparatory's low-income kids hit 51.9% proficiency in ELA — a number the same group reaches at 38.2% statewide. If you're trying to read past zip-code-driven test scores, that's the signal worth weighing.

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

Ask about the discipline philosophy and what a typical suspension is for. Numbers can't tell you whether a campus feels strict or chaotic — a visit can.

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 Mission Preparatory's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 49.2% of students at Mission Preparatory met or exceeded the state standard in ELA and Math combined, and 25.7% exceeded it. The gap between those numbers matters: 23.5% of students are at the proficiency floor, while 25.7% 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. 312 student-subject combinations were assessed.
How does Mission Preparatory rank in California?
Mission Preparatory ranks #2,040 among California elementary schools by Scope Score, placing it in the 64th 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 Mission Preparatory getting better or worse?
Based on 2025 CAASPP data, proficiency at Mission Preparatory decreases by 12.2 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 Mission Preparatory?
20.6% of students at Mission Preparatory are chronically absent (missing 10% or more of school days), compared to the California average of 17.9%. The suspension rate is 3.4%. 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 Mission Preparatory compare to other schools in San Francisco?
Mission Preparatory scores 49/100 (64th 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 491 students.

Data source: California Department of Education, CAASPP 2024-25. 262 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.
