Johnson County High School

Johnson County High School serves 563 students in grades 9–12 in Mountain City, Tennessee, a small town in the Appalachian region of the northeastern part of the state. The school is part of Johnson County Schools, a district ranked in the bottom 4% of Tennessee districts — yet the high school itself ranks in the 44th percentile of high schools statewide (222nd out of 400), earning 2 stars. This means the high school is a relative bright spot within a district that faces significant challenges, though it still sits below the statewide midpoint.

Academically, the most pressing concern is math. Just 21.8% of students are proficient in Geometry, less than half the state rate of 42.3%, and Algebra I and Algebra II proficiency also lag well behind state averages. English and history are relative strengths: English II proficiency (54.1%) is close to the state average (58.1%), and US History actually exceeds the state rate. Many scores are above the district average, suggesting the high school is doing somewhat better than the district's feeder schools.

The most urgent warning signs are in graduation and attendance. The graduation rate has fallen sharply from 96.9% in 2021–2022 to 80.4% in 2024–2025, while the dropout rate has tripled to 10.1%. Chronic absenteeism affects 23.3% of students — well above the state's 18.3% and nearly double the district's 12.3%. All this comes despite rising investment: per-student spending has grown over 50% in four years to $16,661, and the student-teacher ratio is a favorable 13.5:1. The only nearby school, Carter County Alternative School in nearby Elizabethton, serves a very different mission and student population, so direct comparisons are not meaningful. The bottom line: Johnson County High School has solid English and history instruction and good staffing, but math proficiency, attendance, and graduation rates need urgent attention.
