Best ZIP codes for schools by state

How we rank school quality

The School Quality Index summarizes district math and reading proficiency and four-year graduation outcomes. Results based on very small student samples are excluded, and missing measures do not count as zero.

A ZIP's score reflects the districts serving the area, with greater influence from districts covering more of the ZIP. It measures outcomes, not school ratings, spending, or individual schools.

Each state sets its own tests and proficiency cut scores, so the index compares ZIPs well within a state but not across states. That is why we rank ZIPs only within each state.
