Summary:
ZIP code 53045 in Brookfield, Wisconsin contains just one middle school: Wisconsin Hills Middle, which serves grades 6 through 8 and enrolls 812 students as part of the Elmbrook School District. Because it is the only middle school in the ZIP code, there is no local peer to compare against, so the most useful benchmarks are the district and the state.
By state standards, this school is elite. It ranks 32nd of 643 Wisconsin middle schools in 2025–2026, placing it in the 95th percentile with a 5-star rating, and it has earned 5 stars in each of the last three school years. Its ranking trend is positive, moving from 42nd to 52nd and then up to 32nd. Proficiency is far above state averages in every reported subject and grade, beating the state by roughly 20 to 30 percentage points. In 8th-grade Social Studies, the school actually edges the district average (85.98% vs. 85.31%). In most other tested areas it sits slightly below district averages—typically by 2 to 3 points—but the district itself is one of the top-ranked in Wisconsin, so this reflects an unusually strong system rather than a weak school.
Attendance and completion outcomes are another bright spot: chronic absenteeism is 3.3%, compared with 17.3% statewide, and the dropout rate is 0.0% versus 1.1% statewide. Seven of eight reported proficiency areas improved year over year, with the largest gains in 6th-grade Math (+8.87 points), 8th-grade English Language Arts (+7.49 points), and 8th-grade Social Studies (+7.01 points); only 7th-grade Math slipped, by 0.85 points. Contextually, 9.24% of students qualify for free/reduced-price lunch, per-student spending is $15,727, and the student-teacher ratio is 14.2.
