Summary:
Waterloo, Wisconsin is home to a single middle school: Waterloo Middle, which serves grades 5–8 and enrolls 118 students as part of the Waterloo School District. Because it is the only middle school in the city, every middle-grade result for Waterloo reflects this one school, and families comparing options locally have a single, well-defined picture to consider.
Academically, the school ranks 445 of 643 for 2025–2026 — the 31st percentile with 2 stars — while its district ranks 348 of 432, the 19th percentile with 1 star, so the middle school is the stronger part of its local system. Compared with the state, Waterloo Middle was below average in 8 of 10 reported subject-grade results. Its bright spots are 8th grade English Language Arts at 58.33% proficient (state 54.38%) and 8th grade Science at 56.25% (state 51.86%). Mathematics is the clearest concern: every math grade fell below the state, with 7th grade math at 32.08% versus 55.67%, a gap of 23.59 points, and an average math gap of about 15.15 points. Year over year, 8th grade improved in ELA (+11.66 points), math (+7.08), and science (+6.25), while 7th grade declined in both ELA (−4.49) and math (−9.92).
Attendance and dropout indicators are comparatively strong. Chronic absenteeism is 12.1%, below the state's 17.3% but slightly above the district's 11.8%, and the dropout rate is 0.0%, better than the district's 0.5% and the state's 1.1%. About 44.07% of students qualify for free/reduced lunch, per-student spending is $16,998, and the student-teacher ratio is 14.7. Rankings have drifted slightly from the 33rd to the 32nd to the 31st percentile over three years while holding a 2-star rating, suggesting steady but below-middle statewide performance, with 8th grade ELA and science, low dropout, and better-than-state attendance as the main strengths, and math across all grades as the priority to watch.
