Summary:
Grundy County Schools is served by a single high school, Grundy County High School, which enrolls 486 students in grades 9–12 in the rural Coalmont, TN area. Because it is the district’s only high school, its performance represents the entire district in state rankings, and it currently sits in the lower third of Tennessee high schools, with a 2-star rating.
Academically, math is the clearest area of concern at Grundy County High School. In 2025–2026, Algebra II proficiency was just 13.3% versus 37.3% statewide, Geometry was 20.7% versus 42.3%, and Algebra I was 18.7% versus 32.3% — with 10th-grade Algebra II a striking 14.3% versus 63.9% statewide. English II is the school’s relative strength at 46.6% proficiency (state: 58.1%), though English I dropped from 33.1% to 25.8% year over year. Biology I showed strong improvement, rising from 26.0% to 36.8% proficiency, with 10th graders nearly matching the state average (39.6% vs. 41.3%). US History remains below average at 26.1%.
Beyond test scores, the school graduates 84.8% of students versus 90.5% statewide, and its 8.0% dropout rate is above the state’s 6.7%. On a positive note, chronic absenteeism (16.5%) is better than the Tennessee average (18.3%), meaning attendance is not the primary issue. Per-student spending is $11,364, though no state comparison is available, and free/reduced lunch data was not reported. The school’s state rank has slipped from the 44th percentile in 2023–2024 to the 32nd–33rd percentile over the last two years. Overall, parents should know that while Grundy County High School has notable strengths in English II and improving Biology scores, targeted support in mathematics and stronger efforts to keep students on track to graduation are the most urgent priorities.
