Summary:
Lannon, Wisconsin has just one school in this data set: Lannon Elementary, an elementary school serving grades K–4 with 350 students, part of the Hamilton School District. Because no middle, high, or alternative schools are listed for the city, the most useful comparisons come from the school's district and from Wisconsin as a whole rather than from local peers.
Lannon Elementary is a standout. In 2025–26 it ranked 38th of 1,039 ranked Wisconsin schools — the 96th percentile, roughly the top 3.7%, with 5 stars. Its rank has climbed steadily, from 50th of 1,061 in 2023–24 to 45th of 1,044 in 2024–25, and it has held a 5-star rating all three years. Test results reinforce this: on the Forward Exam in both 2024–25 and 2025–26, the school exceeded the state proficiency rate in every subject and grade shown, by margins ranging from 18.9 to 36.0 percentage points. Chronic absenteeism in 2024–25 was 5.7%, slightly better than the district's 5.9% and far below Wisconsin's 17.3%.
The picture is strong but not uniform. Third-grade results improved notably, with ELA up from 77.78% to 88.1% and math from 76.39% to 85.71%. Fourth-grade results were mixed: math slipped from 85.71% to 76.62%, and science and social studies remained below district averages, though all stayed comfortably above state averages. That matters because the Hamilton School District is itself elite — 11th of 432 districts, 97th percentile, 5 stars — so trailing the district is not the same as trailing the state. Resource context includes $15,674 in per-student spending and a 14.8 student-teacher ratio. Keep the limits in mind: one school only, and test data covering grades 3 and 4 only.
