Is it getting better · CAASPP 2019 to 2025
Has held the 88th-percentile line every tested year since 2019.
Most rating sites would stop at “65% proficient” and call it done. Los Osos deserves a closer read. Two in five of its students qualify for free or reduced lunch (California: 64%) — and reading the numbers without that context misreads the school.
Los Osos's low-income kids hit 74.3% proficiency in ELA — a number the same group reaches at 38.2% statewide. If you're trying to read past zip-code-driven test scores, that's the signal worth weighing.
624 tested · 1 of 1 grade published
Los Osos High scores 71 of 100 on SchoolScope's Scope Score — the 88th percentile of 1,647 California high schools (CDE CAASPP 2025).
This school hasn't fully recovered from the pandemic: 65% meet the standard today, versus 69% in 2019 — a gap worth asking about on a visit.

UC is one road of many — the full destination mix for the class of 2023 is below. And who applied isn't who the school taught: the ratio between the two reflects the self-selected pool of students who chose to apply, not what happened in the classroom. By the state's 2023 count, 81% of this class's predecessors enrolled in college somewhere within a year. More of the class of 2023 enrolled at community colleges (237) than at UC (115).

Worth a school visit
Ask what the school is working on next. Strong numbers tell you where a school is, not where it's going.
- Ask whether extra support — tutoring, counseling, small groups — reaches kids across income lines, not just the students already ahead.
- Ask whether the tour can step into a working classroom — watch how the teacher handles a student who's stuck.
- Ask to tour while school's in session, and notice how hallways and transitions feel — culture shows up between classes, not just in them.
- Ask how the school communicates with families when a child starts to struggle.
- Ask what a typical day looks like for a new student in the first few weeks.
Questions
Frequently asked questions
Is Los Osos High a good high school?
Los Osos High has a Scope Score of 71 out of 100, placing it in the 88th percentile of California high schools and ranked #191 statewide. 39.5% of students exceeded the state standard on the 2025 CAASPP assessment, which is 19.7 percentage points above the California average of 19.8%. The Scope Score weights 7 dimensions for high schools: graduation rate (25%), exceeded standard (22%), college/career readiness (20%), met or exceeded (proficient) (18%), chronic absenteeism (5%), suspension rate (5%), and ELPAC English Learner proficiency (5%). Data source: California Department of Education CAASPP 2025, analyzed by SchoolScope.
What are Los Osos High's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 65.0% of students at Los Osos High met or exceeded the state standard in ELA and Math combined, and 39.5% exceeded it. The gap between those numbers matters: 25.5% of students are at the proficiency floor, while 39.5% went beyond it. Most rating sites report only the combined "proficient" number. SchoolScope surfaces the exceeded-vs-met split because it shows how many students go beyond the standard rather than only meeting it. 1,245 student-subject combinations were assessed.
How does Los Osos High rank in California?
Los Osos High ranks #191 among California high schools by Scope Score, placing it in the 88th 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.
What is the attendance and school culture like at Los Osos High?
25.2% of students at Los Osos High are chronically absent (missing 10% or more of school days), compared to the California average of 23.1%. The suspension rate is 3.4%. 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 Los Osos High compare to other schools in Rancho Cucamonga?
Los Osos High scores 71/100 (88th percentile) among California high schools. To compare with nearby schools, SchoolScope shows the same metrics side by side: exceeded rate, proficiency, growth trajectory, and school culture indicators. The school serves 2,759 students. Use the schools in Rancho Cucamonga page or the map view to compare all high schools nearby.
How does Los Osos High serve low-income and underrepresented students?
At Los Osos High in Rancho Cucamonga, 74.3% of low-income students met or exceeded the ELA standard in 2025, compared to 63.9% district-wide and 38.2% statewide. Los Osos High outperforms its district average for low-income students by 10.4 percentage points in ELA. Other subgroups: Low-Income students (43.3% Math proficient); Hispanic students (75.7% ELA proficient). The largest proficiency gap is 45.7 percentage points for english learner students. Data source: California Department of Education, CAASPP 2024-25. 284 students tested. SchoolScope shows disaggregated test scores by demographic subgroup so you can see how a school performs for your child's specific group — not just the school-wide average. Subgroup data is context, not part of the Scope Score: we don't penalize schools for who they serve. See our equity approach.
What AP courses are offered at Los Osos High?
Los Osos High's teachers are authorized to teach 25 of the 40 AP subjects the College Board offers, per the 2025 - 2026 AP Course Audit: 2-D Art and Design, African American Studies, Biology, Calculus AB, Calculus BC, Chemistry, Chinese Language and Culture, Computer Science Principles, Drawing, English Language and Composition, English Literature and Composition, Environmental Science, French Language and Culture, Human Geography, Macroeconomics, Physics 1, Psychology, Research, Seminar, Spanish Language and Culture, Spanish Literature and Culture, Statistics, U.S. Government and Politics, United States History, World History: Modern. Authorization means the school may teach a course, not that a section is running this year, and it's separate from AP exam pass rates. Data source: College Board AP Course Audit, analyzed by SchoolScope.
How many students from Los Osos High go to UC?
In fall 2025, 107 Los Osos High graduates enrolled at University of California campuses, universitywide. That figure can't be split into a per-campus sum — students apply to several UC campuses at once, so campus-level counts don't add up to the universitywide total. UC is one destination among many: this says nothing about graduates who chose a CSU, a private college, a community college, or work, and it is a count, not a rate or a ranking. Data source: University of California Office of the President (UC Information Center), fall 2025 admissions cycle.

A closer look at the evidence
Los Osos High: reading the evidence
Los Osos posts 39.5% exceeding the standard — versus 19.8% statewide — with climate numbers better than most. That doesn't make it perfect. It makes it worth a visit to find what numbers can't measure.
Subject proficiency describes tested students, while graduation describes a graduating cohort. These figures are not successive stages followed by the same students.
This label means the data doesn't clearly sort the school one way or the other — ask what the school is proud of, and what it's working on.
