Arroyo High · San Lorenzo

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

Arroyo posts 17.8% exceeding the standard — versus 15.8% 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.

ranked #538 statewide · #2 of 5 in San Lorenzo Unified

Arroyo High scores 55 of 100 on SchoolScope's Scope Score — the 75th percentile of 2,160 California high schools (CDE CAASPP 2025).

Measures test performance, attendance, and climate — not arts, community, or your kid. How we score →

🌱 Building Momentum — 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.

Most rating sites would stop at “45% proficient” and call it done. Arroyo deserves a closer read. The school sits in San Lorenzo, where three in five students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

Arroyo's low-income kids hit 56.1% 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.

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.

UC is one road of many — the full destination mix for the class of 2023 is below.

Frequently asked questions

Is Arroyo High a good high school?

Arroyo High has a Scope Score of 55 out of 100, placing it in the 75th percentile of California high schools and ranked #538 statewide. 17.8% of students exceeded the state standard on the 2025 CAASPP assessment, which is near the California average of 15.8%. 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 Arroyo High's CAASPP test scores?

On the 2025 CAASPP Smarter Balanced Assessment, 45.1% of students at Arroyo High met or exceeded the state standard in ELA and Math combined, and 17.8% exceeded it. The gap between those numbers matters: 27.3% of students are at the proficiency floor, while 17.8% 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. 655 student-subject combinations were assessed.

How does Arroyo High rank in California?

Arroyo High ranks #538 among California high schools by Scope Score, placing it in the 75th 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 Arroyo High?

15.4% of students at Arroyo High are chronically absent (missing 10% or more of school days), which is better than the California average of 30.2%. The suspension rate is 3.5%. 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 Arroyo High compare to other schools in San Lorenzo?

Arroyo High scores 55/100 (75th 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 1,499 students. Use the schools in San Lorenzo page or the map view to compare all high schools nearby.

How does Arroyo High serve low-income and underrepresented students?

At Arroyo High in San Lorenzo, 56.1% of low-income students met or exceeded the ELA standard in 2025, compared to 25.7% district-wide and 38.2% statewide. Arroyo High outperforms its district average for low-income students by 30.4 percentage points in ELA. Other subgroups: Low-Income students (26.6% Math proficient); Hispanic students (50.9% ELA proficient). The largest proficiency gap is 45.6 percentage points for english learner students. Data source: California Department of Education, CAASPP 2024-25. 213 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 Arroyo High?

Arroyo High's teachers are authorized to teach 13 of the 40 AP subjects the College Board offers, per the 2025 - 2026 AP Course Audit: 2-D Art and Design, Biology, Calculus AB, Chinese Language and Culture, English Language and Composition, English Literature and Composition, Environmental Science, Physics 1, Psychology, 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 Arroyo High go to UC?

In fall 2025, 48 Arroyo 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.
