Summary:
Zip code 53183 covers Wales, Wisconsin, and its six public schools all belong to the Kettle Moraine School District. The area lists one elementary school and five high schools, with no middle or alternative schools — though KM Connect actually serves grades 6–12, so the split is not a clean one. Total enrollment is 1,598 students: 333 at Wales Elementary and 1,265 across the five high schools, which share the Oak Crest Drive campus.
The standout is High School of Health Sciences, ranked #1 of 533 Wisconsin high schools with 5 stars, a 100% graduation rate, 0% dropout, 6.4% chronic absenteeism, and 10th-grade proficiency in the high 80s to low 90s in every subject — well above both the district and the state. KM Global School (71 students) and Kettle Moraine High (869 students) rank #28 and #29 of 533, both 5 stars. Wales Elementary is also 5 stars, ranking #68 of 1,039 and beating the state in every tested subject and grade, including 5th-grade math at 87.5% against a state average of 51.81%, despite carrying the area's highest free/reduced-lunch rate.
Results vary widely from school to school. School for Arts and Performance posts strong ELA at 84%, but math sits at 36% and science at 56%, dropping it from the 98th percentile a year earlier to the 83rd. KM Connect, with just 35 students, ranks in the 21st percentile with sharply polarized results — 100% in several middle-school subjects but 20–30% on 10th-grade ACT subjects. Notably, spending and class size do not predict outcomes here, and every school beats the state's 17.3% chronic absenteeism rate.
