What the numbers actually mean

Most rating sites report "63% proficient" and stop there. We think that number deserves more context — here's what we found when we looked deeper:

39.5% 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 23.2% met it. That exceeded rate is 17.9 points above the state average of 21.6%. That's 8.5 points above the Rosemead Elementary district average of 31.0%. 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 87 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.

Chronic absenteeism? Missing 10%+ of enrolled school days. This is an official California Dashboard accountability indicator. is 2.4%, better than the state average of 18.1%.

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
86th percentile performance with 68% economically disadvantaged students — this is genuinely hard to achieve and reflects real school quality, not demographic advantage.
Who this school is great for
Families prioritizing upward trajectory — proficiency improves 9.2pp G3→G5
Families where consistent attendance and school culture matter — absenteeism is well below state average
Families looking for a low-discipline-incident environment
Worth checking: If your child is already exceeding standard, check how the school stretches high performers
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: 39.5%
17.9pp 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: 62.7%
19.8pp 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): +9.2pp
Scores improve 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.

SchoolScope derived
School Climate
Chronic absenteeism: 2.4%

Absenteeism reflects school culture and family engagement — an official CA Dashboard accountability indicator.

Limitation: 10% threshold is the same for all schools regardless of demographics or geography.

CDE Attendance 2025

Low suspension rates correlate with positive school culture and restorative practices.

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
