Summary
Central Middle is a grades 6–8 school in Hartford, WI, serving 419 students as part of the Hartford J1 School District, and it ranked 429th of 643 Wisconsin middle schools in 2025–2026 — the 33rd percentile with 2 stars. That marks a long slide: Central Middle sat in the 60th–68th percentile from 2015–2016 through 2018–2019, was still at the 63rd percentile in 2020–2021, and has fallen every year since (47th, 42nd, 37th, 34th, 33rd). It has been a 2-star school every year since 2021–2022.
Compared with nearby middle schools, Central Middle is an outlier. Slinger Middle ranks at the 96th percentile, Merton Intermediate at the 99th, North Shore Middle at the 98th, Templeton Middle at the 94th, and Kennedy Middle at the 71st — all well above Central's 33rd. Central also has the highest chronic absenteeism of these schools at 26.1%, against a nearby range of 2.3%–12.1% and a state rate of 17.3%, and the highest free/reduced-lunch rate at 39.38%. Yet it spends $15,897 per student, more than many neighbors, with a student-teacher ratio of 12.8, lower than most. Those resources have not yet shown up in results.
Grade-level scores reveal a slide through middle school. Sixth grade is a relative bright spot: ELA proficiency (55.56%) is close to the state's 54.95%, and math (56.25%) is above the state's 53.6%. By 8th grade the gaps are wide — ELA 37.68% vs. 54.38% statewide, math 43.48% vs. 53.67%, science 36.23% vs. 51.86%, and social studies 50.72% vs. 64.63%. Results also vary by student group: the school's statewide effectiveness ranking for African American students is strong (16th of 125, 87th percentile, 4 stars), while low-income students rank at the 16th percentile, down sharply from the low 30s in the two prior years.
