Summary:
Zip code 37313 contains a single public high school, Grundy County High School, serving grades 9–12 in Coalmont, Tennessee, with about 486 students.
Because this is the only high school in the area, it is both the sole option for local families and the primary driver of outcomes for Grundy County Schools — in fact, the school’s graduation rate, dropout rate, chronic absenteeism, and test scores are identical to the district’s figures, meaning the high school fully represents the district’s high school results. The school has maintained a 2-star rating for three consecutive years, even though its district is rated 1 star. Academically, the school trails the state in every tested subject, with the largest gaps in math: Algebra II proficiency is just 13.3% (24 points below the state average) and Geometry is 20.7% (21.6 points below). English II is the strongest subject at 46.6% proficient, though still 11.5 points behind the state. On a positive note, Biology I proficiency jumped by nearly 11 points in one year, rising from 26.0% to 36.8%, and Algebra I improved by 4.9 points. However, English I dropped by 7.3 points, and Geometry and US History also declined slightly. Graduation rate is 84.8% versus the state’s 90.5%, while the dropout rate is 8.0% versus 6.7% statewide.
Encouragingly, chronic absenteeism at 16.5% is actually better than the Tennessee average of 18.3%, and the school spends a substantial $11,364 per student. The school has slipped in state ranking from the 44th percentile in 2023–2024 to the 33rd percentile in 2025–2026, even as some scores improved — a sign that other schools across Tennessee are also getting better. For parents, this means Grundy County High School offers a supportive attendance environment and some bright spots in English and Biology, but math readiness and graduation outcomes remain clear areas of concern that deserve close attention.
