Summary:
The Union Grove Union High School School District covers the village of Union Grove in Racine County, Wisconsin — roughly midway between Milwaukee and Kenosha — and serves grades 9–12 through a single high school: Union Grove High, which enrolls 1,032 students at 3433 S Colony Ave. Because the district has only one high school, district results and school results are essentially the same, so everything below describes Union Grove High directly.
Student outcomes are the clearest strength. The graduation rate is 98.3%, compared with Wisconsin's 92.0%, and the dropout rate is 0.0% versus the state's 1.1%. Chronic absenteeism sits at 7.2%, less than half Wisconsin's 17.3%. Academically, mathematics is the standout: 49.21% proficient versus 42.93% statewide in 2025–2026, and 48.05% versus 42.73% in 2024–2025. Science also beats the state both years, at 43.65% vs. 43.20% and 44.92% vs. 43.42%, though by narrower margins.
English Language Arts is the weakest area and the gap is growing. Proficiency fell to 43.65% from 46.88%, a 3.23-point drop, while the state stayed nearly flat at 48.47%, widening the shortfall to 4.82 points. Social Studies was essentially even with the state in 2024–2025 (47.62% vs. 47.67%) but slipped 1.53 points behind in 2025–2026. The school's rank trend is nonetheless upward, moving from the 34th percentile in 2023–2024 to the 51st and then 54th, with stars rising from 2 to 3; the district snapshot shows 222 out of 432, 49th percentile, 2 stars. Context: 11.72% free/reduced lunch, $14,434 per student, and a 16.2 student-teacher ratio.
