Most rating sites would stop at “10% proficient” and call it done. Potrero deserves a closer read. The school sits in Potrero, where three in four 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.

Frequently asked questions
Is Potrero Elementary a good elementary school?

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 Potrero Elementary's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 10.2% of students at Potrero Elementary met or exceeded the state standard in ELA and Math combined, and 2.2% exceeded it. The gap between those numbers matters: 8.0% of students are at the proficiency floor, while 2.2% 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. 229 student-subject combinations were assessed.
How does Potrero Elementary rank in California?
Potrero Elementary ranks #5,461 among California elementary schools by Scope Score, placing it in the 5th 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 Potrero Elementary getting better or worse?
Based on 2025 CAASPP data, proficiency at Potrero Elementary decreases by 0.9 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 Potrero Elementary?

The suspension rate is 0.5%, 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 Potrero Elementary compare to other schools in Potrero?
