Schools in Zip Code 54204

Zip code 54204 covers Brussels, Wisconsin, and is home to three public schools serving students from pre-kindergarten through 12th grade: Southern Door Elementary (PK–5, 482 students), Southern Door Middle (6–8, 205 students), and Southern Door High (9–12, 304 students). All three sit at the same campus address and belong to the Southern Door County School District, which enrolls 991 students across these buildings and ranks 71st of 432 Wisconsin districts — the 84th percentile, with 4 stars. Every one of the three schools also earned 4 stars in the 2025–2026 rankings.

Each school is strong in a different way. Southern Door Middle has the best combined profile: the lowest chronic absenteeism (6.9%), the lowest student-teacher ratio (10.4), the highest per-student spending ($16,735), and exceptional 8th grade results — 80% proficient in math, 85% in social studies, and 81.67% in science, all far above state averages. Southern Door High posts a 100% graduation rate and a 0.3% dropout rate, with above-state results in ACT ELA (58.62%) and ACT math (56.9%). Southern Door Elementary improved from 3 stars to 4 stars and shines in the upper grades — 5th grade math at 75.36% and 4th grade social studies at 83.56% — while serving the highest share of students from low-income families (40.25% free/reduced lunch) on the lowest per-student spending ($13,824).

A few watch points are worth noting. Elementary 3rd grade ELA (49.15%) and math (50.85%) fell below state averages in 2025–2026, a reversal from the prior year. High school chronic absenteeism (15.4%) is above the district's 10.4% but still below the state's 17.3%, and ACT Science (43.1%) is now roughly even with the state. Grade-level results in these small schools can swing sharply from year to year, so single-year comparisons should be read with caution.
