ZIP code 54562 covers Three Lakes, Wisconsin, where three public schools in the Three Lakes School District serve students from pre-kindergarten through 12th grade — Three Lakes Elementary (PK–6, 160 students), Three Lakes Junior High (7–8, 73 students), and Three Lakes High (9–12, 156 students), for a total of 389 students. The district as a whole ranks 58th of 432 Wisconsin districts, placing it in the 87th percentile with 4 stars.
Three Lakes Junior High is the academic standout, ranking 39th of 643 middle schools in 2025–2026 — the 94th percentile with 5 stars, up sharply from 4 stars the year before. Its proficiency tops the state in every reported subject, including Math 7th at 85% versus 55.67% statewide, and it reports a 0.0% dropout rate. Three Lakes High is the most improved, climbing from 1 star in 2023–2024 to 4 stars in 2025–2026, with a 95.1% graduation rate, 0.6% dropout rate, and ACT Math at 57.14% and ACT Science at 53.57%, both well above state.

Two areas deserve attention. Chronic absenteeism climbs with grade level: 13.2% at the elementary school (below the state's 17.3%), but 20.6% at the junior high and 21.6% at the high school, both above district and state averages. The elementary school's 3rd grade Math sits at 46.67%, below the district's 56% and the state's 54.75%, down from 84.21% the prior year — though small cohorts can swing widely. Spending and class size also differ: the high school spends the most per student ($25,860) while the junior high spends the least ($22,744) yet achieves the strongest results, and student-teacher ratios are more favorable at the secondary level (10.1 and 10.2) than at the elementary school (14.4).
