Most rating sites would stop at “60% proficient” and call it done. Los Osos deserves a closer read. The school sits in Los Osos, where more than half of students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

The headline number: 53.7% of low-income students met the ELA standard — versus 38.2% for the same group statewide.

The honest read: the share exceeding holds steady across grades; the floor slips 6.5pp. The state average falls 0.5pp over the same span. A strong 6th grader at Los Osos doesn't typically widen their lead by 8th grade. One question worth asking on a tour: are the strongest students being pushed, or coasting? A school visit and conversation with teachers will tell you more than this number.

What are Los Osos Middle's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 60.3% of students at Los Osos Middle met or exceeded the state standard in ELA and Math combined, and 30.5% exceeded it. The gap between those numbers matters: 29.8% of students are at the proficiency floor, while 30.5% pushed past it. Most rating sites report only the combined "proficient" number.

How does Los Osos Middle rank in California?
Los Osos Middle ranks #346 among California middle schools by Scope Score, placing it in the 80th 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 Los Osos Middle getting better or worse?
Based on 2025 CAASPP data, proficiency at Los Osos Middle decreases by 9.4 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.
