Summary:
Union Public School District contains one high school, Union High School, which serves grades 9–12 in Union, Mississippi, with an enrollment of 280 students. Because it is the district's only high school, its results directly determine the district's high-school-level rankings, graduation rate, and test scores.
Union High School is a standout performer in Mississippi. It is currently ranked 24th out of 224 high schools statewide (89th percentile) for 2025–2026, and the district ranks 19th out of 134 districts. The school earned 5 stars in the two previous rankings and 4 stars in the most recent year. The graduation rate is an impressive 96.9%, well above the state average of 89.2%. In MAAP End-of-Course testing, the school outperformed the state in every subject in both reported years, including Algebra I (86.7% vs. 66.0%), English II (59.4% vs. 49.3%), and Biology (78.1% vs. 63.1%). The largest margin over the state was in U.S. History, with a +22.0 point difference.
Notably, Union High School achieves these results while serving a high-poverty population, with 98.93% of students receiving free or reduced lunch. The student-teacher ratio is a favorable 9.2, suggesting smaller class sizes and potentially more individualized instruction. However, chronic absenteeism is 24.7%, slightly above the state average of 23.9%, meaning roughly one in four students is chronically absent. English II is the relative weak point, with proficiency below 60%, while Algebra, Biology, and U.S. History are the school's strongest subjects. Between 2024–2025 and 2025–2026, Algebra I improved, but English II and Biology declined, making these areas worth monitoring. Overall, Union High School remains a strong, high-performing rural school whose success defines the district's high school performance.
