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.

🌱 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.

Arroyo's most underrated number
56.1% of low-income students met the ELA standard — versus 38.2% for the same group statewide. That's the strongest kind of signal a school can post: it holds across income lines.
The 7 things our score weighs
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. 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, 71% of this class's predecessors enrolled in college somewhere within a year. More of the class of 2023 enrolled at community colleges (141) than at UC (44).
