Summary:
Zip code 62931 has one high school, Hardin County High School, serving grades 9–12 with 175 students. The school’s 2025–2026 graduation rate was 83%, compared with 90% statewide, while chronic absenteeism was 51%, versus 24% statewide and 35% in Hardin County CUSD 1. The clearest concern is chronic absenteeism: the school’s rate was 27 percentage points above the state rate.
Because there is only one school in the list, it is both the highest and lowest by default; that is not a meaningful local distinction. In every 2025–2026 test comparison with a reported school result, Hardin County High School was below the state. The largest gaps were in ELA: 24 points below on 10th-grade PreACT Secure and 22 points below on 9th-grade PreACT Secure; its 11th-grade ACT ELA result was 11 points lower. The school was 15 points below the state in 11th-grade ACT science and 5 points below in 9th-grade PreACT science. Across the reported comparisons, the average gap was 18 points in ELA and 10 in science. The state suppressed all three current-year school math results. SchoolDigger ranked the school 476th of 620 statewide, in the 23rd percentile.
Results changed in different directions across matched tests, so the trend is mixed. From 2024–2025 to 2025–2026, 11th-grade ACT ELA rose 6 points, and its state gap narrowed from 18 to 11 points; 10th-grade PreACT ELA fell 15 points, and its gap widened from 11 to 24 points. Ninth-grade PreACT science rose 18 points, narrowing its state gap from 26 to 5 points, while 11th-grade ACT science fell 7 points and its gap widened from 9 to 15 points. SchoolDigger’s ranking was 537th of 698 in 2024–2025 and 512th of 697 in 2023–2024, both also in the 23rd percentile or higher. As context, 53% of students were free/reduced lunch eligible in 2024–2025, and the student-teacher ratio was 14 to 1 that year.
