Best ZIP codes for schools in Pennsylvania
Ranked by the School Quality Index: district math and reading proficiency and graduation rates, weighted by how much of each district falls in the ZIP.
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.
Only ZIPs with at least 1,000 residents are ranked, so a handful of households cannot top the list. 1,154 Pennsylvania ZIPs qualify.
