Summary
Wilson Elementary is a PK–5 school in Janesville, Wisconsin, serving 256 students as part of the Janesville School District, which ranks 257th of 432 districts in the state. Wilson itself ranked 814th of 1,039 Wisconsin elementary schools in 2025–26 — the 22nd percentile, or 1 star. That is a modest step up: from 2015–16 through 2024–25 the school stayed between the 13th and 20th percentile, mostly at 1 star, so 2025–26 is its best showing in a decade even though it remains in the bottom quarter of schools.
The school serves a student body with a very high level of economic need: 92.19% of students qualified for free or reduced-price lunch in 2024–25, 14–15 points above the next-highest nearby schools, including Jackson Elementary, Adams Elementary, Lincoln Elementary, and Madison Elementary. Chronic absenteeism was 33.3%, well above the district's 22.0% and the state's 17.3%, roughly 10 points above Adams and Madison, and more than triple Harrison Elementary's 10.2%. Wilson also has the highest per-student spending ($19,683) and the lowest student-teacher ratio (8.3) in its nearby comparison group, yet the lowest rank percentile and lowest approximate average proficiency of that group — Harrison, Monroe Elementary, Roosevelt Elementary, and Van Buren Elementary are all 4-star schools in the 71st–87th percentile.
Results vary sharply by grade. Third grade is a relative bright spot: ELA at 52.94% proficient is essentially at the state average, and math at 58.82% is above the state and close to the district. Fourth grade is much weaker — ELA 32.61% and math 33.33%, both far below district and state, social studies 39.13% (about 31 points below the district), and science only 17.39%, roughly 36 points below the state. Fifth grade ELA (41.38%) and math (44.83%) also trail. Special education students rank in the 24th percentile (1 star). Attendance has improved from 48.2% chronic absenteeism in 2021–22, but attendance, 4th grade science and social studies, and lagging student groups remain the clearest areas to watch.
