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:

32.4% 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 28.9% met it. That exceeded rate is 16.9 points above the state average of 15.5%. That's 8.0 points above the Tamalpais Union High district average of 24.4%. The gap between "met" and "exceeded" can reveal how much a school's curriculum challenges students beyond proficiency.

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.


Before you visit
Questions worth asking and signals worth checking
Who this school is great for
Families where consistent attendance and school culture matter — absenteeism is well below state average
Worth checking: 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
Graduation rate: 95.9%
8.3pp above state avg (state avg 87.6%)
25% weight

Graduation rate is the most fundamental high school outcome measure.

Limitation: Adjusted cohort method may not capture students who transfer or complete via alternative paths.

CDE Graduation 2025
Exceeded standard: 32.4%
16.9pp above state avg (state avg 15.5%)
22% 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
College readiness: 84.7%
AP exam pass rate above state avg (state avg 35.5%)
20% weight

College readiness shows how well a school prepares students for post-secondary success.

Limitation: Uses AP pass rate or A-G completion as proxy — doesn’t capture trade or vocational readiness.

CDE College/Career 2025
Met or exceeded: 61.3%
26.7pp above state avg (state avg 34.6%)
18% 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
School Climate
Chronic absenteeism: 18.7%

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: 3.1%
1.0pp below state avg (state avg 4.0%)

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

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

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.

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 high school Scope Score uses 7 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
