Summary:
ZIP code 55920 is Byron, Minnesota, where four public schools serve students from pre-kindergarten through 12th grade — Byron Primary School (PK–2), Byron Intermediate School (3–5), Byron Middle School (6–8), and Byron Senior High School (9–12) — with a combined enrollment of 2,342 students. All four belong to the Byron Public School District, which ranks 11th of 458 Minnesota districts (98th percentile) and holds 5 stars.
Each school has a distinct strength. Byron Intermediate School is the math standout: 81.6% of students are proficient in math, which is 17.2 points above the district and 36.7 points above the state, with every tested grade far ahead of state results. Byron Middle School leads in reading at 71.6%, about 23 points above the state, and its state rank has improved from 57th to 27th over three years. Byron Senior High School posts a 94.2% graduation rate and a 1.1% dropout rate — well ahead of the state's 84.9% and 4.2% — plus science proficiency of 61.0% versus 25.5% statewide. All three ranked schools hold 5 stars and sit near the 95th percentile in Minnesota.
A few comparisons are worth noting. Science is uneven across the district: the high school is far above both the district and state, the intermediate school is above the state but slightly below the district, and the middle school's 33.3% trails the district's 45.4%. Class sizes grow with grade level, with student-teacher ratios rising from 11.7 at the primary school to 15.9, 17.9, and 21.9 at the intermediate, middle, and high schools. Byron Primary School has no test-score or rank data, which is typical for a PK–2 school and should not be read as a weakness; it has the smallest classes and the highest free/reduced-lunch rate at 18.11%, while rates across the district remain comparatively low.
