Summary:
ZIP code 53546 is home to seven public schools — six elementary schools and one middle school, with no high school inside the ZIP — split between the Janesville School District (six schools) and the Milton School District (one school), together serving about 2,583 students.
Performance varies widely. Kennedy Elementary (4 stars, 85th percentile) and Harrison Elementary (4 stars, 84th percentile) are the strongest ranked schools in the Janesville group, scoring above both district and state averages on every listed 2025-26 test. Van Buren Elementary is also 4 stars (71st percentile) and rose from 3 stars. Harmony Elementary in Milton posts the highest proficiency in the ZIP — grade 3 ELA 73.77% and math 86.89% — though only grade 3 is tested there. At the other end, Jackson Elementary (39th percentile) and Lincoln Elementary (38th percentile) are 2-star schools; Lincoln is the clearest improvement story, moving from 1 star to 2 stars and raising its average proficiency from about 34.7% to 50.9%. Edison Middle, the only middle school and the largest at 587 students, is mixed: 8th grade math, science, and social studies are above district and state, but 7th grade ELA (41.38%) is below both.
Chronic absenteeism is a key signal. Edison has the ZIP's highest rate at 24.2%; Harmony's 3.7% is the lowest, followed by Kennedy (10.1%) and Harrison (10.2%). Higher spending and smaller classes do not track with better results here — Jackson ($16,999) and Lincoln ($17,075) spend the most and score lowest, while Van Buren spends the least ($12,978) and earns 4 stars — suggesting spending reflects student need. Results also vary by grade, so families should weigh specific grade-level data, not just school-wide ratings.
