Summary:
ZIP code 54204 is home to exactly one middle school: Southern Door Middle in Brussels, Wisconsin, serving grades 6–8 with 205 students as part of the Southern Door County School District, a 4-star district ranked 71 of 432 in Wisconsin (84th percentile).
Because there is only one middle school here, there is no in-ZIP peer to compare against, so the useful benchmarks are the district and the state. Southern Door Middle has earned 4 stars in each year of its rank history, placing 104 of 643 (84th percentile) in 2025–26, 80 of 628 (87th percentile) in 2024–25, and 133 of 641 (79th percentile) in 2023–24 — consistently in the top quartile. Every reported Forward Exam subject and grade in both 2024–25 and 2025–26 was above the state average. The strongest 2025–26 results were 8th grade Science at 81.67% proficient versus 51.86% statewide, 8th grade Social Studies at 85% versus 64.63%, and 8th grade Mathematics at 80% versus 53.67%. Across all eight reported 2025–26 tests, the school averaged 71.3% proficient against a state average of 55.5%. One caution: 7th grade dipped in 2025–26, with Math falling from 85.71 to 63.64 and ELA from 78.57 to 63.64, though both remained above the state (by 7.97 and 8.31 points). Meanwhile 8th grade improved in Science (+13.18), Math (+8.77), Social Studies (+5.55), and ELA (+3.89).
Attendance and dropout figures are favorable: chronic absenteeism is 6.9%, compared with 10.4% in the district and 17.3% statewide, and dropout is 0.0%, versus 0.2% districtwide and 1.1% statewide. For context, the school reports 32.2% free/reduced lunch, $16,735 per-student spending, and a 10.4 student-teacher ratio, though state and district comparisons for those measures are not provided, so no conclusions should be drawn from them. District results closely mirror the school — identical in 2025–26 and nearly identical in 2024–25 — meaning at the middle-school level, the district's reported performance largely reflects this one school.
