Summary:
Zip code 37683 is served by a single high school: Johnson County High School in Mountain City, Tennessee, which educates 563 students in grades 9–12. The school belongs to the Johnson County Schools district, which ranks in the bottom 4% of Tennessee districts with a zero-star rating. However, the high school itself earns two stars and sits at the 44th percentile statewide, making it a clear bright spot within a struggling district. In fact, Johnson County High School outperforms its district in every single TNReady subject, often by dramatic margins — for example, US History proficiency is 43.8% at the school versus just 22.1% districtwide.
Parents will find some genuinely encouraging academic trends. The school posted major one-year gains in Biology I (from 24.6% to 44.2% proficiency), Algebra I (7.8% to 22.1%), Algebra II (16.8% to 29.1%), and English II (40.9% to 54.1%). US History is the only subject at or above the state average, reaching 43.8% versus the state's 42.4%. English II is the school's strongest overall subject at 54.1%, close to the state's 58.1%. However, Geometry is a severe weak point at 21.8% proficiency compared to the state's 42.3% — a 20-point gap that barely improved year-over-year. English I also dropped sharply from 39.7% to 31.9%, so this mixed English performance deserves attention.
The most serious concerns involve attendance and completion. Chronic absenteeism sits at 23.3%, well above the state average of 18.3% and nearly double the district's 12.3% rate. The graduation rate of 80.4% trails the state's 90.5% by 10 points, and the dropout rate of 10.1% is about 1.5 times the statewide figure — though it is far better than the district's extremely high 21.5% dropout rate. With spending of $16,661 per student, Johnson County High School has real momentum in math and science, but parents should keep a close eye on Geometry, English I, and attendance challenges, as these areas will likely determine whether the school's recent gains can be sustained.
