Summary:
Erin School District is a single-school district in Wisconsin, serving students in grades PK–8 at Erin Elementary, located at 6901 County Highway O in Hartford, WI. About 399 students attend. The district holds a 4-star rating and ranks 82nd out of 432 Wisconsin districts, placing it in the 81st percentile. Because there are no middle, high, or alternative schools, every district-level metric mirrors this one school. Its rank history shows real movement: 405th of 1,061 with 3 stars in 2023–2024, then 167th of 1,044 with 4 stars in 2024–2025, settling at 287th of 1,039 with 4 stars in 2025–2026.
Academically, Erin Elementary scores above the state average in all four tested subjects in both years. In 2024–2025, school averages were 65.4% in English Language Arts versus 52.8% statewide, 75.9% in mathematics versus 53.9%, 86.5% in social studies versus 63.1%, and 80.0% in science versus 50.4%. In 2025–2026, scores dipped but stayed above state: 64.2% ELA versus 54.0%, 69.3% math versus 53.7%, 77.1% social studies versus 65.1%, and 68.1% science versus 52.7%. Mathematics is the most consistent strength, with every tested grade above state in both years. Only two results fell below state: 5th grade ELA in 2024–2025 (47.62% versus 51.26%) and 3rd grade ELA in 2025–2026 (50% versus 52.08%).
Attendance stands out: chronic absenteeism is 1.4%, compared with 17.3% statewide, and the dropout rate is 1.0% versus 1.1% for Wisconsin. For context, 15.29% of students qualify for free or reduced lunch, per-student spending is $11,824, and the student-teacher ratio is 15.2; the data include no state comparisons for the last two figures. Parents should note that 2025–2026 results were lower than 2024–2025 in most subjects, and that grade-level year-to-year changes reflect different groups of students rather than the same children improving or slipping.
