Measures test performance, attendance, and climate — not arts, community, or your kid. How we score →
Most rating sites would stop at “41% proficient” and call it done. Waterloo deserves a closer read. The school sits in Stockton, where three in five students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

What are Waterloo Elementary's CAASPP test scores?

The gap between those numbers matters: 29.2% of students are at the proficiency floor, while 11.7% 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. 519 student-subject combinations were assessed.
How does Waterloo Elementary rank in California?
Waterloo Elementary ranks #816 among California middle schools by Scope Score, placing it in the 52nd percentile. This ranking is based on a weighted composite of 2025 CAASPP test performance (exceeded and met rates), grade-level growth (Grade 6 to grade 8 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 Waterloo Elementary getting better or worse?
