Summary:
Hillsboro School District in Wisconsin is home to a single elementary school, Hillsboro Elementary, which serves about 220 students in grades PK–5 and is the only school in the district tested at the elementary level, so every comparison available is between this school and the state rather than between schools.
Hillsboro Elementary has climbed steadily in the state rankings: 778th of 1,061 (27th percentile, 1 star), then 623rd of 1,044 (40th percentile, 2 stars), and most recently 450th of 1,039 — 57th percentile and 3 stars. That sits well above its own Hillsboro School District, which ranks 304th of 432 districts (30th percentile, 1 star). Test results in 2025‑26 averaged about 61.1 across eight assessments versus a state average of 54.7. Science was the standout at 76.47% proficient against 53.46% statewide, and social studies came in at 70.59% versus 65.51%. The newest third‑grade class posted the highest numbers anywhere in the data — 78.26% in English language arts and 73.91% in math. Fourth‑ and fifth‑grade math, though, remain below state, with fifth‑grade math at 42.50% versus 51.81%.
Chronic absenteeism is the school's most remarkable figure: 2.0%, compared with 5.2% district‑wide and 17.3% statewide. About 44.55% of students qualify for free or reduced lunch, per‑student spending is $18,875, and the student‑teacher ratio is 11.5 to 1. The main caution is size: grade‑level test groups appear to run roughly 17–25 students, so one student can shift a grade's percentage by several points. Much of the year‑over‑year gain also traces to a strong incoming third grade while the older cohorts stayed flat, so a third year of data would clarify how much reflects instructional improvement versus cohort composition.
