Summary:
There is one high school in the Deerfield Community School District: Deerfield High, which serves grades 9–12 and enrolls 207 students in Deerfield, Wisconsin. Because it is the district's only high school, its results also stand in for the district's high school performance. The district ranks 279 of 432 in Wisconsin, placing it in the 35th percentile with 2 stars.
Deerfield High's strongest results are in graduation and Social Studies. In 2024–2025 it reported a 100% graduation rate and a 0% dropout rate, compared with 92% and 1.1% statewide. Social Studies proficiency stayed above state in both reported years: 51.92% versus 48.25% in 2025–2026, and 57.45% versus 47.67% in 2024–2025. Math ACT proficiency jumped from 30% to 42%, a 12-point gain that leaves it only 0.93 points below the state. The school also reports a student-teacher ratio of 11.6 and per-student spending of $17,341. Its rank improved from the 32nd percentile in 2024–2025 to the 47th percentile in 2025–2026, though it remains a 2-star school.
Areas to watch include attendance and two ACT subjects. Chronic absenteeism is 18.9%, higher than the district's 11.2% and the state's 17.3%, even as students graduate. ACT English Language Arts and Science remain below state in both years — ELA at 42% versus 48.47% and Science at 36% versus 43.20% in 2025–2026. About one in five students, 21.26%, qualifies for free/reduced lunch. With only 207 students, year-to-year score changes can reflect just a few students, so trends should be read with caution.
