How We Rank High Schools

Each school receives a composite score (0–100) built from 4 federal data signals, weighted to reflect what matters most at the high school level. All signals are normalised against national benchmarks so a school's score reflects its standing across the entire US, not just within this district.

Graduation Rate
40%
The most direct outcome measure available at the school level. Percentage of students who complete high school, from EDFacts federal data.
Neighborhood Opportunity
25%
Harvard Opportunity Atlas score reflecting long-run economic outcomes for children raised in this neighbourhood.
Student-Teacher Ratio
20%
Lower ratio = smaller classes. Normalised against national range.
Per-Pupil Expenditure
15%
Annual district spending per enrolled student from the NCES F-33 Finance Survey.
Test scores are excluded: they are not published as consistent open federal data across all states, making reliable cross-district comparison impossible with this signal alone.

Frequently Asked Questions
About This Data

All figures on this page come directly from US federal open datasets: NCES Common Core of Data (enrollment, school characteristics, student-teacher ratios), NCES F-33 Finance Survey (per-pupil expenditure), EDFacts (graduation rates), and the Harvard Opportunity Atlas (neighbourhood opportunity scores). Federal data is published on an annual cycle and may not reflect the very latest school-year changes. Rankings reflect available data and should be used as a starting point — not a substitute for visiting schools or consulting district resources directly. What this ranking does not measure: teacher quality, classroom culture, extracurricular programmes, school safety, or parent and student satisfaction.
