What the numbers actually mean
Most rating sites report "61% proficient" and stop there. We think that number deserves more context — here's what we found when we looked deeper:
33.6% 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 27.8% met it. That exceeded rate is 16.3 points above the state average of 17.3%. That's 3.2 points above the Livermore Valley Joint Unified district average of 30.4%. 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 G6 → 2025 G8): students gained 32 scale score points? Pseudo-cohort tracking: we compare this school's G6 class from a prior year to the G8 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.
SchoolScope cohort tracking · Same cohort tracked across years using SBAC scale scores — stronger than single-year cross-grade comparisonCalifornia's Dashboard shows ELA performance maintained and Math increased year-over-year. 30.8% of English learners reached Level 4 (Well Developed) on ELPAC.
Chronic absenteeism? Missing 10%+ of enrolled school days. This is an official California Dashboard accountability indicator. is 7.8%, better than the state average of 19.1%.
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

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.
✓Exceeded standard: 33.6%16.3pp 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: 61.3%21.8pp 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.
CDE CAASPP 2025▼Growth (G6→G8): -10.0ppScores decline across grades (state avg +0.8pp)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✓Chronic absenteeism: 7.8%11.3pp below state avg (state avg 19.1%)10% weight
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: 1.3%3.0pp below state avg (state avg 4.2%)5% weight
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✓EL proficiency (ELPAC): 30.8%14.0pp above state avg (state avg 16.8%)5% weight
ELPAC Level 4 measures how well a school develops English proficiency — a school-quality signal for its EL population.
Limitation: Only available for schools with English Learner students. Weight redistributes to other dimensions when not applicable.
CDE ELPAC 2025The 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.
- –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
