Summary
Waterloo Middle is a small public middle school in Waterloo, Wisconsin, serving grades 5–8 with 118 students in the Waterloo School District. The district ranks 348 of 432 districts statewide (19th percentile, 1 star), and the school ranks 445 of 643 Wisconsin middle schools in 2025–2026 — the 31st percentile, 2 stars. That places it below most nearby middle schools, including Columbus Middle, Lake Mills Middle, Glacial Drumlin School, Prairie View Middle, Central Heights Middle, Deerfield Middle, Patrick Marsh Middle, and Marshall Middle, but above Riverside Middle (26th percentile). Waterloo has not always been here: it reached the 44th percentile in 2018–2019, fell to the 21st in 2020–2021, and has held in the 31st–35th percentile range since.
Math is the clearest challenge. In 2025–2026, proficiency was below the state in every tested grade: 39.02% in grade 5, 39.29% in grade 6, 32.08% in grade 7, and 43.75% in grade 8, with grade 7 the widest gap. Columbus Middle and Lake Mills Middle generally score much higher. Other subjects are stronger: grade 8 science was 56.25% (state: 51.86%) and grade 8 ELA 58.33% (state: 54.38%); grade 8 social studies was 60.42%, just below the state's 64.63%. Attendance is a bright spot — chronic absenteeism was 12.1% in 2024–2025, well below the state's 17.3% and better than most nearby schools, and the dropout rate returned to 0.0%.
Waterloo spends $16,998 per student, more than many higher-performing neighbors, and 44.07% of students qualified for free/reduced lunch in 2024–2025, up from 36.21% in 2022–2023. Its student-teacher ratio of 14.7 is the highest among nearby comparison schools, which range from 11.0 to 13.7 — a combination worth asking about. Subgroup results are uneven: English learners ranked in the 76th percentile and special education students in the 45th in 2025–2026, while low-income students sat at the 22nd. Because the school is small, these figures can swing sharply year to year.
