What the numbers actually mean

Most rating sites report "40% proficient" and stop there. We think that number deserves more context — here's what we found when we looked deeper:

18.0% 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 22.0% met it. That exceeded rate is near the state average of 17.3%. That's 3.8 points below the Mark West Union Elementary district average of 21.8%. The gap between "met" and "exceeded" can reveal how much a school's curriculum challenges students beyond proficiency.

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
  • — Growth data unavailable for this school — the score overweights proficiency, which tends to correlate with household income

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

Questions worth asking and signals worth checking
Who this school is great for
Families who value a smaller school community — 107 students
Worth checking: Families wanting top-end academic rigor — more students meet the bar (22%) than exceed it (18%)
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: 18.0%
0.7pp above state avg (state avg 17.3%)
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: 40.0%
0.5pp above state avg (state avg 39.5%)
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.

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
Suspension rate: 5.3%

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

Limitation: Schools may differ in reporting practices — some underreport to improve metrics.

CDE Discipline 2025
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 middle school Scope Score uses 4 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
