Summary:
ZIP code 53046 covers Lannon, Wisconsin, and contains just one public school in the available data: Lannon Elementary, an elementary school serving grades K–4 with 350 students. No middle, high, or alternative schools are listed for this ZIP, so every local public-school data point centers on this single campus, which belongs to the Hamilton School District — itself ranked 11th of 432 Wisconsin districts and rated 5 stars.
Lannon Elementary is a 5-star school and has climbed in the statewide standings, moving from 50th of 1,061 schools (95th percentile) in 2023–2024 to 38th of 1,039 (96th percentile, roughly the top 4%) in 2025–2026. On the 2025–2026 Forward Exam it beat the state average in every tested subject and grade, from 3rd-grade English Language Arts at 88.1% proficient versus 52.08% statewide (+36.02 points) to 4th-grade Social Studies at 84.42% versus 65.51% (+18.91 points). Results are more mixed against its own district: 3rd-grade ELA and Math topped district averages, 4th-grade ELA was essentially even, and 4th-grade Math, Social Studies, and Science trailed the district. Chronic absenteeism is a standout at 5.7%, far below the state's 17.3% and slightly under the district's 5.9%.
Year over year, the biggest gains came in 3rd-grade ELA (+10.32 points) and 3rd-grade Math (+9.32 points), while 4th-grade Math slipped 9.09 points — still at 76.62% proficient, well above the state's 52.87%. The school reports 10.29% free/reduced lunch participation, $15,674 in per-student spending, and a 14.8 student-teacher ratio; no state benchmarks are supplied for those three figures. Because the data cover only one K–4 school, parents should note that middle and high school outcomes for this area are not reflected here.
