Summary:
ZIP code 55313 covers 11 schools serving roughly 4,490 students from preschool through 12th grade, and it is essentially a single district: Buffalo-Hanover-Montrose Schools runs 7 of the 11 schools and enrolls about 95.6% of local students. The district ranks 133 of 458 in Minnesota (71st percentile, 4 stars). Two schools dominate enrollment: Buffalo Senior High (1,681 students) and Buffalo Community Middle (1,160), together about 63% of the ZIP. The four Buffalo elementaries add 1,417 students, while the small alternative and specialized programs range from just 8 to 84 students.
Northwinds Elementary is the strongest elementary, beating both district and state in math (63.4%), reading (57.6%) and science (35.5%), with 3rd-grade math at 77.3%. Buffalo Senior High posts a 96.7% graduation rate and 1.5% dropout rate, well ahead of state figures, and ranks in the 81st percentile. Buffalo Community Middle is steady and well-ranked (80th percentile, 4 stars), with 8th-grade math at 61.2%. All three are 4-star schools.
Tatanka Elementary STEM School is the weakest elementary, with math 39.8%, reading 42.5% and science 14.8%, below district and state. Science is a soft spot broadly — Buffalo Community Middle (21.5%), Discovery Elementary (17.1%) and Tatanka all trail state science, and science scores fell at several schools versus the prior year. Outcome gaps among alternative programs are stark: Phoenix Learning Center 80.0% graduation, Terra Nova School 57.1%, and Wright Technical Center Alternative Learning Center 17.3% graduation with 17.3% dropout. Many test values for the smallest programs are suppressed by the state, so they cannot be fully judged from test data.
