Summary:
ZIP code 54889 covers Turtle Lake, Wisconsin, where four schools serve students from prekindergarten through 12th grade in the Turtle Lake School District: Turtle Lake Elementary (PK–5, 215 students), Turtle Lake Middle (6–8, 96), Turtle Lake High (9–12, 119), and Laker Online (PK–12, 15). Total listed enrollment is 445 students, with the elementary school holding about 48% of that. The district itself is rated 223rd of 432 Wisconsin districts, at the 48th percentile with 2 stars — but school-level results vary far more than that mid-tier rating suggests.
Turtle Lake Middle is the clear standout: 158th of 643 schools, 75th percentile, 4 stars, up from 57th percentile a year earlier. Its 8th grade results are well above state in ELA (81.08% vs. 54.38%), Social Studies (83.78% vs. 64.63%), and Science (78.38% vs. 51.86%), though math is closer to average and 7th grade math (42.86%) trails the state. Turtle Lake High pairs excellent completion metrics — a 100% graduation rate, 0.8% dropout rate, and 7.8% chronic absenteeism against the state's 17.3% — with 2025–2026 ACT scores below state in all three reported subjects, and its rank slipped to 49th percentile with 2 stars. Turtle Lake Elementary sits at 38th percentile with 2 stars; 5th grade math (74.19% vs. 51.81%) is a bright spot, but 4th grade ELA, math, and science are all below state.
Attendance is a district-wide strength for the traditional schools — Middle 3.2%, Elementary 4.4%, High 7.8% — all well under the state's 17.3%. Spending doesn't track outcomes simply: the high school spends the most ($18,922 per pupil) while the highest-ranked middle school spends $14,772. Laker Online, with 15 students, has the highest free/reduced lunch rate (66.67%), lowest spending ($10,514), highest reported student-teacher ratio (28.3), and 0.0% dropout, but no test scores or rank history, and its current school-level chronic absenteeism is not reported. Small grade-level cohorts also make year-to-year swings large.
