Best Public Schools in Zip Code 53092

ZIP code 53092 in Mequon, Wisconsin, is served by five public schools—two elementary (PK–5), two middle (6–8), and one high school (9–12)—all part of the Mequon-Thiensville School District, which ranks #13 of 432 Wisconsin districts. The district enrolls 3,054 students across these buildings, and every one of the five schools holds a 5-star rating. The five schools are Homestead High, Wilson Elementary, Donges Bay Elementary, Steffen Middle, and Lake Shore Middle.

Each school stands out differently. Lake Shore Middle is the top-ranked building at #15 of 643 middle schools statewide (98th percentile), with the largest ranking jump, best middle-school math scores, smallest classes (12.3:1), and highest per-pupil spending ($18,349). Homestead High ranks #25 of 533 high schools (95th percentile), with a 98.4% graduation rate and 0.0% dropout rate. Donges Bay Elementary made the biggest year-over-year surge to #36 of 1,039 (97th percentile) and has the highest 3rd-grade math score. Wilson Elementary has the lowest chronic absenteeism (2.4%), while Steffen Middle climbed to #27 of 643 (96th percentile) with the largest science gain.

Proficiency across these schools runs 1.4 to 1.7 times the state level, with gaps of 15 to 36 points in every tested subject. Spending and class size do not track outcomes—the highest- and lowest-spending schools are both top performers. Four of five schools improved rankings; only Homestead slipped slightly (from #20 to #25). Chronic absenteeism is low district-wide, but Homestead (8.2%) and Lake Shore (6.8%) are above the district rate of 5.4%, while Wilson’s 2.4% is far lower. Poverty indicators are low and do not predict performance—Steffen has the highest free/reduced lunch rate (14.83%) yet ranks #27 statewide. Middle-school science made a synchronized leap at both Steffen and Lake Shore, while elementary improvement split: Donges Bay gained in ELA and math, and Wilson was flat. Social studies is Homestead’s relative soft spot, declining from 68.98 to 65.22. Bottom line: this is a small, high-performing district where all schools beat the state by wide margins, and the differences between them are narrow.
