Best School Districts in Maryland (2026)
This ranking covers 25 rated public school districts in Maryland,
scored using NCES EDFacts state assessment data for the 2017–18 school year — the most recent district-level federal collection we have processed.
Each district's reading and math proficiency rates are averaged, then ranked against other districts in the same state to produce a 1–10 score.
A district's score reflects how its students perform on state assessments relative to same-state peers —
it is not a direct measure of teaching quality, school culture, or individual student outcomes.
Always visit schools, talk to local families, and contact districts directly before making decisions.
