Summary:
ZIP code 54634 in Wisconsin is home to two schools serving a combined 472 students, both part of the Hillsboro School District: Hillsboro Elementary, which covers PK–5 with 220 students, and Hillsboro High, which serves grades 6–12 with 252 students. There is no separate middle school, so middle-grade results are reported under the high school.
Hillsboro Elementary is the clearest standout. It has climbed from 1 star and the 27th percentile in 2023–2024 to 3 stars and the 57th percentile in 2025–2026. Chronic absenteeism is just 2.0%, compared with 5.2% for the district and 17.3% for the state. Third grade ELA (78.26% proficient) and math (73.91%), plus 4th grade science (76.47%), are well above state averages. However, 4th and 5th grade ELA and 5th grade math land near or below state levels, so results vary by grade. Its per-student spending is $18,875 with an 11.5:1 student-teacher ratio.
Hillsboro High is more mixed. Graduation (92.5%) and dropout (0.4%) rates beat state figures, and ACT Math at 50% exceeds the state's 42.93%. But its ranking swung from 4 stars and the 70th percentile in 2024–2025 down to 2 stars and the 45th percentile in 2025–2026, and its chronic absenteeism of 7.6% is higher than the elementary school's. The biggest concern is middle-school math: 6th, 7th, and 8th grade proficiency is only 27.27%, 24.14%, and 29.41%, against state averages above 53%. Overall, the elementary school is improving steadily while the high school shows solid completion outcomes but volatile academics and a serious middle-grade math gap.
