Summary:
ZIP code 53027 — Hartford, Wisconsin — is served by a single public high school: Hartford High, located at 805 Cedar St and enrolling 1,324 students in grades 9–12. It is the only school in the Hartford Union High School School District, so district-wide numbers and school numbers are identical in every category; there is no second school in the ZIP to compare against. Comparisons here are therefore Hartford High versus the state of Wisconsin, and Hartford High versus its own past years.
The school's strengths are real. Its graduation rate is 96.8% against a state figure of 92.0%, and its dropout rate of 0.6% is roughly half the state's 1.1%. On the ACT, students scored above the state in three of four subjects in the most recent year — English Language Arts at 54.43% proficient (state 48.47%), Mathematics at 51.07% (state 42.93%) and Science at 51.83% (state 43.20%). Resources look solid too: a 16.6-to-1 student-teacher ratio and about $14,345 spent per student, with 23.34% of students qualifying for free or reduced-price lunch. Statewide, the school is rated 3 stars at the 65th percentile.
Two things are worth watching. Social Studies was the only subject below the state line, at 41.92% proficient versus 48.25%, and it fell about 9 points from the prior year's 51.19% — though that subject uses a different exam (Forward) than the ACT subjects, so it shouldn't be read as directly comparable. Chronic absenteeism, at 18.3%, also edges slightly above the state's 17.3%. Proficiency declined in all four subjects year over year while state figures barely moved, and the school's rank slipped from 97 of 431 to 184 of 533 — a percentile change from 77 to 65 that lands close to its 2023–24 mark of 63.
