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

Bel Aire posts 46.8% exceeding the standard — versus 21.3% 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.

Bel Aire Elementary scores 72 of 100 on SchoolScope's Scope Score — the 93rd percentile of 5,744 California elementary schools (CDE CAASPP 2025).

💪 Strong All-Around — Ask about what we don't score — class size, electives, the feel of a classroom — strong numbers everywhere on paper don't mean every classroom feels the same.

Most rating sites would stop at “77% proficient” and call it done. Bel Aire deserves a closer read. It sits at the 93rd percentile of 5,744 California elementary schools — but the ranking is the least interesting thing on this page.

The headline number: 46.8% of students scored in the top band on the state test. The California average is 21.3%.

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 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.

What are Bel Aire Elementary's CAASPP test scores?

On the 2025 CAASPP Smarter Balanced Assessment, 77.1% of students at Bel Aire Elementary met or exceeded the state standard in ELA and Math combined, and 46.8% exceeded it. The gap between those numbers matters: 30.3% of students are at the proficiency floor, while 46.8% 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. 649 student-subject combinations were assessed.

How does Bel Aire Elementary rank in California?

Bel Aire Elementary ranks #408 among California elementary schools by Scope Score, placing it in the 93rd 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 Bel Aire Elementary getting better or worse?

Based on 2025 CAASPP data, proficiency at Bel Aire Elementary decreases by 0.6 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 Bel Aire Elementary?

10.1% of students at Bel Aire Elementary are chronically absent (missing 10% or more of school days), which is better than the California average of 17.9%. The suspension rate is 0.6%, 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.
