ZIP Codes With Perfect School Scores (2026)

A perfect 100 school score on NeighborScore means a ZIP's public schools both cover the full grade range and post math and reading proficiency at the top of the scale. Ada, Minnesota (56510) is the standout, pairing that perfect school score with a 95 crime score for a 91 overall — the best-schooled ZIP in the country by our index.

What a perfect school score requires

The school score blends two inputs from federal education data: grade coverage (does the ZIP host schools spanning elementary through high school?) and academic proficiency (how do math and reading results compare?). A ZIP reaches 100 only when both are strong — broad coverage alone is not enough.

Where the perfect scores are

Beyond Ada, MN (56510), western Maryland fields two perfect-100 school ZIPs in Oakland (21550) and Accident (21520), both also scoring 89–90 overall.

The list spans the country: Ewing, Nebraska (68735), Reserve, New Mexico (87830), and Bradford, Vermont (05033) all earn a flawless school score, reflecting tight-knit districts with strong proficiency results.

Read perfect scores with care

Small districts can swing year to year because a single graduating class is a large share of the sample. A perfect score is a strong signal, but parents should still check the most recent state report card and tour the schools directly.

Frequently asked questions

Does the score include private schools?

No. The school score is based on public-school data from federal sources, so areas served mainly by private schools may score lower than their true quality.

Where does the proficiency data come from?

From the U.S. Department of Education's NCES Common Core of Data and EDFacts files. For the full scoring method, see how NeighborScore works. This is a research tool, not an enrollment recommendation.
