How We Rank Elementary Schools

Each school receives a composite score (0–100) built from 4 federal data signals, weighted to reflect what matters most at the elementary 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.

Neighborhood Opportunity
40%
Harvard Opportunity Atlas score for the school's neighbourhood. Higher means children from this area historically achieve stronger economic outcomes.
Student-Teacher Ratio
30%
Lower ratio = smaller classes = more individual attention per child. Normalised against national range.
Per-Pupil Expenditure
20%
Annual district spending per enrolled student from the NCES F-33 Finance Survey. Compared against national average.
Free Lunch Rate
10%
Percentage of students qualifying for free/reduced-price lunch. Used as a neighbourhood economic-context signal.
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), 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.
