Lakeside High: High scores, healthy climate, strong attendance. We looked for a catch — we didn't find one.

Lakeside High has a Scope Score of 50 out of 100, placing it in the 63rd percentile of California high schools and ranked #800 statewide. 9.4% of students exceeded the state standard on the 2025 CAASPP assessment, which is 6.4 percentage points below the California average of 15.8%. The Scope Score weights six dimensions for high 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.

On the 2025 CAASPP Smarter Balanced Assessment, 28.9% of students at Lakeside High met or exceeded the state standard in ELA and Math combined, and 9.4% exceeded it. The gap between those numbers matters: 19.5% of students are at the proficiency floor, while 9.4% 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. 713 student-subject combinations were assessed.

Lakeside High ranks #800 among California high schools by Scope Score, placing it in the 63rd percentile. This ranking is based on a weighted composite of 2025 CAASPP test performance (exceeded and met rates), 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.

32.9% of students at Lakeside High are chronically absent (missing 10% or more of school days), compared to the California average of 30.2%. The suspension rate is 2.8%. SchoolScope includes these culture metrics in the Scope Score because they reflect day-to-day school experience in ways test scores alone cannot.
