Summary:
ZIP code 53182 contains exactly one high school — Union Grove High — a grades 9–12 school with 1,032 students in Union Grove, Wisconsin, part of the Union Grove Union High School School District. Because it is the only high school in the area, the most useful comparisons are between this school, its district, and the state of Wisconsin rather than with a local peer school.
The school's clearest strengths are in getting students to finish and attend. Its graduation rate is 98.3%, well above Wisconsin's 92.0%, and its reported dropout rate is 0.0% versus the state's 1.1%. Chronic absenteeism is 7.2%, less than half the statewide 17.3%. Academically, math is the anchor: 49.21% of students were proficient in 2025–2026 versus 42.93% statewide, a gap of about 6 points, and math improved year over year. Science remains slightly above the state (43.65% vs. 43.20%), though the advantage has narrowed. Notably, this school's math proficiency exceeds its ELA proficiency, the opposite of the statewide pattern.
The main concerns are English Language Arts and Social Studies. ELA fell from 46.88% to 43.65% proficiency, leaving the school 4.82 points below the state and widening a gap that was 1.74 points the prior year. Social Studies slipped from essentially even with the state (47.62% vs. 47.67%) to 1.53 points below (46.72% vs. 48.25%). Overall, the school's state rank improved from the 34th percentile (2 stars) in 2023–2024 to the 54th percentile (3 stars) in 2025–2026, even as these two subjects declined. Context figures include 11.72% free/reduced lunch, $14,434 per-student spending, and a 16.2:1 student-teacher ratio.
