Summary

Erin Elementary in Hartford, WI is a PK–8 public school of 399 students and the only school in the Erin School District, a small district ranked 82nd of 432 Wisconsin districts (81st percentile, 4 stars) that sits in a band of small, high-performing K–8 districts between Hartford, Oconomowoc, Hartland and Slinger. Statewide, Erin ranks 287th of 1,039 elementary schools in 2025–26 (72nd percentile, 4 stars) — squarely mid-range for its own history, which has ranged from the 62nd to the 84th percentile over the last ten reported years, with 4 stars in eight of them and 3 stars in 2023–24 and 2018–19.

The school's clearest strength is a broad proficiency edge over the state: in 2025–26 Erin was at or above the state rate in 15 of 16 grade-level subject tests, with math running +15.6 points and ELA +10.0 points above state averages (science +15.4, social studies +12.0). Middle-school math is the standout — 7th grade at 79.55% and 8th grade at 77.08% proficiency, versus state rates near 54–56%, with 8th grade math actually edging out Stone Bank Elementary. Chronic absenteeism is the most distinctive number: 1.4% in 2024–25 against a 17.3% state rate, down from 16.7% in 2021–22. Erin achieves this on the lowest per-pupil spending ($11,824) of all eleven schools compared, with above-average class sizes (15.2 student–teacher ratio) and a higher free/reduced-lunch rate (15.3%) than most nearby schools.

Context matters here, because the neighbors are unusually strong — Swallow Elementary, North Lake Elementary and Stone Bank all rank in the state's top schools. Erin is the lowest-achieving of the four PK–8 peers, but serves the highest-poverty population on the smallest budget, and it outperforms Lincoln Elementary in 4th and 5th grade ELA. Watch items: 3rd grade posted the lowest ELA proficiency of the eleven schools compared (50.0% vs. 52.08% statewide), the ELA advantage has narrowed from +16.1 to +10.0 over two years, and the school slipped from the 84th to the 72nd percentile. With roughly 36–48 students per tested grade, one student moves a grade-level result by 2–3 points.
