Arroyo Elementary scores 35 of 100 on SchoolScope's Scope Score — the 28th percentile of 5,744 California elementary schools (CDE CAASPP 2025).

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

🤝 Culture First — Ask whether the low absenteeism and suspension numbers come from what the school does or from the community it serves — both can produce the same numbers, and only a visit tells you which.

Most rating sites would stop at “30% proficient” and call it done. Arroyo deserves a closer read. The school sits in Ontario, where three in four students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

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 what changes between grade 3 and grade 5 here, and who teaches the older kids.
  • 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.

Data source: California Department of Education CAASPP 2025, analyzed by SchoolScope.

What are Arroyo Elementary's CAASPP test scores?

On the 2025 CAASPP Smarter Balanced Assessment, 29.9% of students at Arroyo Elementary met or exceeded the state standard in ELA and Math combined, and 8.5% exceeded it. The gap between those numbers matters: 21.4% of students are at the proficiency floor, while 8.5% 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. 306 student-subject combinations were assessed.

How does Arroyo Elementary rank in California?

Arroyo Elementary ranks #4,108 among California elementary schools by Scope Score, placing it in the 28th percentile. This ranking is based on a weighted composite of 2025 CAASPP test performance (exceeded and met rates), grade-level growth (Grade 3 to grade 5 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 Arroyo Elementary getting better or worse?

Based on 2025 CAASPP data, proficiency at Arroyo Elementary decreases by 6.7 percentage points from Grade 3 to grade 5 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 elementary Scope Score because it measures what the school does, not just who walks in the door.

What is the attendance and school culture like at Arroyo Elementary?

The suspension rate is 1.1%, indicating a low-discipline-incident environment. SchoolScope includes these culture metrics in the Scope Score because they reflect day-to-day school experience in ways test scores alone cannot.
