Summary
John Muir Middle is a grade 6–8 school at 1400 W Stewart Ave in Wausau, WI, serving 967 students — the largest middle school in this comparison group — as part of the Wausau School District. In 2025-2026 it ranked 253rd of 643 middle schools statewide, the 61st percentile with 3 stars. That is notably stronger than its own district, which ranks 241st of 432 (44th percentile, 2 stars). About 44.88% of students qualify for free or reduced lunch, the student-teacher ratio is 12.9 to 1, and per-pupil spending is $14,541.
John Muir's clearest strengths are Social Studies and 7th-grade math. Eighth-grade Social Studies scores 72.41%, about 7.8 points above the state average, and 7th-grade math sits at 63.23%, roughly 7.6 points above the state. Chronic absenteeism is 13.3%, below both the district (15.2%) and the state (17.3%). The 8th grade is the soft spot: 8th-grade science (52.94%) falls below the district and only slightly above the state. Compared with Horace Mann Middle — 2.65 miles away, in the same district, with similar demographics and higher spending of $15,828 per pupil — John Muir wins 7th grade in both reading and math plus Social Studies, while Horace Mann wins all of 8th grade and 6th-grade math.
The long-term trend is a slide with a recent rebound. John Muir sat in the 70th–75th percentile from 2015–2019, fell to a low of 51st percentile in 2024-25, then recovered to 61st in 2025-26 — still well below its earlier peak. Subgroup results improved for special education students (68th percentile), English language learners (60th), and low-income students (58th). Two areas need watching: Asian students have stayed at 2 stars across recent years (43rd, 36th, 40th percentile), and Hispanic students slid from the 60th percentile to the 22nd before no 2025-26 figure was reported. A gender gap also opened, with female students at the 68th percentile versus male students at the 52nd. For context, Prairie River Middle serves a similar poverty level at higher per-pupil spending but ranks in the 23rd percentile.
