Summary:
Mosinee School District serves about 1,865 students across three schools in central Wisconsin: Mosinee Elementary (PK–3), Mosinee Middle (4–8), and Mosinee High (9–12). The district overall ranks 198th of 432 districts statewide — the 54th percentile, a 3-star rating — a middle-of-the-pack result that hides large differences among the three schools.
Mosinee High is the clear standout, ranking 104th of 533 schools (80th percentile, 4 stars), graduating 97.4% of students versus the state's 92.0%, and posting a 0.0% dropout rate. Its ACT proficiency far exceeds state averages in ELA (64.35% vs. 48.47%), math (56.52% vs. 42.93%), and science (56.52% vs. 43.20%), though social studies slipped to 47.90%, just under the state's 48.25%. Mosinee Elementary is the most improved: third-grade ELA climbed from 47.22% to 59.13%, now above the state's 52.08%, and math rose to 56.90% versus 54.75% statewide. Mosinee Middle is the mixed case — strong in grades 6–8 math (68.70%, 68.18%, 62.50%, all above state) but weak in grade 6 ELA (38.17% vs. 54.95%) and across every grade 4 subject.
Other things parents should know: chronic absenteeism is below the state average at every school (8.8% elementary, 9.3% middle, 12.4% high vs. 17.3% statewide), so attendance is not driving the middle school's reading struggles. Grade 4 is the district's key pressure point — since the elementary school feeds directly into it, watch whether the strong grade 3 gains carry forward. Meanwhile, the high school spends the most per student ($15,899) with the smallest classes, yet the middle school's above-average math shows results are not driven by money alone.
