Summary:
ZIP code 55307 covers Arlington, Minnesota, and contains two public secondary schools in the Sibley East School District: Sibley East Middle School (grades 6–8, 248 students) and Sibley East-Arlington Senior High (grades 9–12, 338 students), for 586 students total. No elementary or alternative schools are listed here, so the available data covers a middle-to-high school pathway at what appears to be a shared campus. The district overall ranks 212 of 458 statewide — the 54th percentile — with 3 stars.
The middle school is the stronger performer, ranking 207 of 546 (62nd percentile, 3 stars) in 2025–26, above the district and holding 3 stars across all three reported years. Reading is its standout strength: 56.3% of students are proficient compared with 48.6% statewide, with 6th grade at 61% and 7th grade at 57%. Science is the biggest concern, at just 6.5% proficient versus 25.5% statewide and down from 14.29% the year before. Math sits at 34.4%, below the state's 44.9%.
The high school has improved markedly, rising from 2 stars to 3 stars and from the 34th to the 51st percentile (234 of 473). Math climbed from 15.63% to 34.8% proficiency, though still below the state's 44.9%. Reading is 40% versus 48.6% statewide, while science is 27.6%, above the state's 25.5% — although its End-of-Course science score trails the state's 35%. Graduation is 84.7%, essentially matching the state's 84.9%, but the dropout rate is 8.2%, roughly double the state's 4.2% and worth watching.
