High Schools in Union County Schools

Union County Schools in Tennessee is home to two high schools: Union County High School, the district's comprehensive high school serving roughly 806 students in grades 9–12, and Union County Alternative Center, a small alternative program serving about 30 students in grades 6–12. The district itself ranks 124th out of 141 Tennessee districts and carries a 1-star rating, yet the data for Union County High School reveal a school with notable strengths beneath its overall averages.

Union County High School outperforms the state in several key areas. Its graduation rate is 93.1% compared to the state average of 90.5%, and its dropout rate of 3.4% is roughly half the state's 6.7%. In subject testing, the school excels in Algebra II at 54.5% proficiency versus 37.3% statewide, and U.S. History at 51.3% versus 42.4% statewide. Its state ranking has also improved from the 39th percentile in 2023–2024 to the 46th percentile in 2025–2026. However, proficiency lags the state in most other subjects, including Algebra I, Biology I, English I, English II, and Geometry, leaving the school's overall average near 36.9% compared to the state's 42.8%. The Union County Alternative Center, by contrast, serves a much smaller and higher-need population. Its only reported test score shows just 10% proficiency in U.S. History, and chronic absenteeism reached 34.5%, illustrating significant academic and attendance challenges.

Chronic absenteeism is a serious concern district-wide. Union County High School's rate of 30.2% is nearly double the state average of 18.3%, and the Alternative Center's rate is even higher at 34.5%. At $16,019 per student, Union County High School's spending is relatively robust, though how those dollars are allocated remains unclear. The Alternative Center lacks graduation, dropout, and spending data, making full evaluation difficult. Union County High School offers strong graduation outcomes and clear strengths in Algebra II and U.S. History, while the Alternative Center serves students with significant academic and attendance challenges. Overall, Union County Schools shows pockets of promise, but attendance and broad subject proficiency remain the biggest areas needing attention.
