Summary:
ZIP code 53555 covers Lodi, Wisconsin, where five schools — three elementary, one middle, and one high school — serve about 1,461 students in grades PK–12, all within the Lodi School District, which ranks 70th of 432 Wisconsin districts at the 84th percentile with 4 stars.
Lodi High is the clear flagship: it is the only school here rated 5 stars, ranking 38th of 533 high schools at the 93rd percentile, up steadily from 83rd two years earlier. Its graduation rate is 98.2% against the state's 92.0%, and its math proficiency tops the state by roughly 25.9 percentage points. Ouisconsing School of Collaboration shows the biggest turnaround, climbing from 2 stars and the 47th percentile to 4 stars and the 78th percentile, with every reported 2025–2026 subject above state averages despite the ZIP's highest free/reduced lunch rate. Lodi Middle stays consistently strong at 4 stars and the 82nd percentile with a 0.0% dropout rate, and Lodi Elementary has improved to the 70th percentile with the ZIP's lowest chronic absenteeism at 2.6%.
Across all five schools, chronic absenteeism is low: every school is under half of Wisconsin's 17.3% rate, ranging from 2.6% at Lodi Elementary to 6.7% at Lodi High. Two areas to watch are 8th grade math and science at Lodi Middle, which slipped to 59.41% and 57.43% though still above state, and 4th grade ELA at Lodi Elementary, at 47.56%, below both district and state. Lodi Primary serves PK–2, so it has no state test scores, and it has the ZIP's highest student-teacher ratio at 17.7. Notably, per-student spending does not track outcomes here: the lowest-spending school, Ouisconsing, is among the strongest improvers.
