Data source: California Department of Education CAASPP 2025, analyzed by SchoolScope.

On the 2025 CAASPP Smarter Balanced Assessment, 77.8% of students at Willowbrook Middle met or exceeded the state standard in ELA and Math combined, and 45.2% exceeded it. The gap between those numbers matters: 32.6% of students are at the proficiency floor, while 45.2% 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. 604 student-subject combinations were assessed.

Willowbrook Middle ranks #125 among California middle schools by Scope Score, placing it in the 94th 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.

Based on 2025 CAASPP data, proficiency at Willowbrook Middle decreases by 0.8 percentage points from Grade 6 to grade 8 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 middle Scope Score because it measures what the school does, not just who walks in the door.

1.6% of students at Willowbrook Middle are chronically absent (missing 10% or more of school days), which is better than the California average of 18.5%. The suspension rate is 2.9%. SchoolScope includes these culture metrics in the Scope Score because they reflect day-to-day school experience in ways test scores alone cannot.
