Duff Language Magnet Academy
A growth engine — students gain measurably more here than at peer schools. Additional funding is translating into measurable improvement
What the numbers actually mean
Most rating sites report "71% proficient" and stop there. We think that number deserves more context — here's what we found when we looked deeper:
44.5% 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 26.0% met it. That exceeded rate is 22.9 points above the state average of 21.6%. That's 16.2 points above the Garvey Elementary district average of 28.3%. 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 83 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.
SchoolScope cohort tracking · Same cohort tracked across years using SBAC scale scores — stronger than single-year cross-grade comparisonChronic absenteeism? Missing 10%+ of enrolled school days. This is an official California Dashboard accountability indicator. is 3.3%, better than the state average of 18.1%.
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
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.
✓Exceeded standard: 44.5%22.9pp 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: 70.5%27.6pp 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): +10.2ppScores 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✓Chronic absenteeism: 3.3%14.9pp below state avg (state avg 18.1%)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: 0.2%1.5pp below state avg (state avg 1.7%)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): 18.7%1.9pp 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
