Schools in Zip Code 53022

ZIP code 53022 covers Germantown, Wisconsin, and is served entirely by the Germantown School District, with five public schools: three elementary schools (PK–5), one middle school (6–8), and one high school (9–12), enrolling about 3,479 students total. The district ranks 54th of 432 Wisconsin districts — the 88th percentile with 4 stars — and every school in the ZIP code earned at least 4 stars in 2025–2026, so families here are choosing between strong options rather than between good and struggling schools.

County Line Elementary is the standout: 66th of 1,039 elementary schools statewide (94th percentile), 5 stars, and just 2.3% chronic absenteeism. Its 5th grade ELA proficiency of 91.18% and 4th grade social studies proficiency of 92.05% are the highest headline scores in the ZIP code. MacArthur Elementary is the most improved, climbing from 241st to 129th over two years, and it posts above-state scores in every reported test despite having the ZIP code's highest free/reduced-lunch share at 22.02%. Rockfield Elementary is the main concern: its rank fell from 144th to 293rd, with 4th grade math and science below the district elementary average, even though it has the smallest classes (13.9 students per teacher) and higher elementary spending.

At the secondary level, Kennedy Middle improved to 4 stars and shines in math, with 7th grade math at 73.58% versus the state's 55.67%, though 8th grade science remains below the state average. Germantown High graduates 97.4% of students (state: 92.0%) with a 0.2% dropout rate, and its ACT math proficiency of 65.08% is more than 22 points above the state's 42.93%. Every school here beats the state's 17.3% chronic absenteeism rate, but the high school's 11.2% is the highest in the ZIP code. Overall, this is a high-performing area with meaningfully different school-level trends.
