What the numbers actually mean

Most rating sites report "68% proficient" and stop there. We think that number deserves more context — here's what we found when we looked deeper:

41.1% of students exceeded standard? Level 4 on California's CAASPP Smarter Balanced Assessment — the state defines four levels: Not Met, Nearly Met, Met, and Exceeded. while 27.3% met it. That exceeded rate is 19.5 points above the state average of 21.6%. That's 3.4 points above the Bonita Unified district average of 37.6%. The gap between "met" and "exceeded" can reveal how much a school's curriculum challenges students beyond proficiency.

We tracked the same cohort across years (2023 G3 → 2025 G5): students gained 86 scale score points? Pseudo-cohort tracking: we compare this school's G3 class from a prior year to the G5 class in the current year. Same school, same cohort aged forward. Uses SBAC scale scores designed for cross-year comparison., suggesting this school is adding measurable value over time.

Data you won't find on other sites: School-level per-pupil spending (not just district averages) · Current-year 2025 data direct from CDE · The exceeded vs. met split that most rating sites collapse into one number

Why the exceeded vs. met split matters → · Scope Score is SchoolScope's analysis of CDE data — not an official CDE rating. How we built this score (and what it misses) →

No single score captures a school. This is a starting point — visit, ask questions, trust your instincts.

What this score doesn't capture
  • — Teaching quality, classroom culture, and how teachers connect with students
  • — Arts, athletics, extracurriculars, and enrichment programs
  • — How well the school serves students with IEPs or gifted learners
  • — Parent community engagement and satisfaction
  • — Whether the curriculum aligns with your family's values

Most of our data is updated once per year and may reflect the prior school year.


Before you visit
Questions worth asking and signals worth checking
What to verify
Score is solid but proficiency rates dropped 2.2 points from G3 to G5. Strong overall, but fewer students hit the benchmark in later grades — could reflect harder standards, cohort differences, or a curriculum gap worth asking about.
Who this school is great for
Students already performing at or above grade level — 41% of students here push past the standard
Families where consistent attendance and school culture matter — absenteeism is well below state average
Families looking for a low-discipline-incident environment
Worth checking: Students needing sustained momentum — proficiency dips between grades; Families wanting small-class-size environments — this is a larger school
These reflect data patterns, not guarantees. Your child's experience will depend on their teacher, grade, and classroom — things no score captures.

Score Factors
Academic Performance
Exceeded standard: 41.1%
19.5pp above state avg (state avg 21.6%)
43% weight

Exceeded rate gets the highest weight because it separates schools that clear the bar from those that raise it.

Limitation: Reflects tested students only — opt-out rates are not published by CDE.

CDE CAASPP 2025
Met or exceeded: 68.4%
25.4pp above state avg (state avg 42.9%)
22% weight

Overall proficiency provides the broadest measure of academic achievement.

Limitation: Combines ‘met’ and ‘exceeded’ — the gap between them matters more than either alone.

CDE CAASPP 2025
Growth (G3→G5): -2.2pp
Scores decline across grades (state avg -3.0pp)
15% weight

Growth measures what the school adds, not what families bring. When available, we track the same cohort across years for a stronger signal.

Limitation: Cohort tracking is school-level (not individual students) — transfers and demographic shifts can affect results. Falls back to cross-sectional comparison when historical data is unavailable.

We make judgment calls about what matters. We believe exceeded scores reveal more than proficiency alone, and that growth matters more than raw test results. Reasonable people could weight these differently — and that's fine. The factors above show exactly what we weighted and why, so you can decide where you agree and where you'd adjust. The elementary Scope Score uses 6 dimensions. How we built this score (and what it misses) →

The Scope Score emphasizes academic performance. It weights test proficiency, the exceeded-vs-met gap, and growth trajectory most heavily. If your family prioritizes arts, athletics, school culture, or teaching philosophy, this score captures some of that indirectly (through absenteeism and suspension) but not all of it. Different families should weight these dimensions differently — the score factors above let you see exactly what drives this number.

How to use this
  • Use for long-term academic patterns, not this week's classroom experience
  • Verify with a recent visit — scores can't capture a school mid-transformation
  • Combine with local context — talk to parents, attend a school board meeting, trust your gut

What are J. Marion Roynon Elementary's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 68.4% of students at J. Marion Roynon Elementary met or exceeded the state standard in ELA and Math combined, and 41.1% exceeded it.

How does J. Marion Roynon Elementary rank in California?
J. Marion Roynon Elementary ranks #779 among California elementary schools by Scope Score, placing it in the 85th 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 J. Marion Roynon Elementary getting better or worse?
