Summary:
Zip code 37902 in Knoxville, Tennessee is served by a single public high school, L N STEM Academy, which enrolls 588 students in grades 9–12 and stands out as one of the very best schools in the state.
If you are considering this area for your child, the most important thing to know is that L N STEM Academy is an elite academic environment. It is currently ranked 3rd out of 400 Tennessee high schools (99th percentile) with a 5-star rating, and it has ranked in the top 25 statewide for three consecutive years. This is especially notable because its home district, Knox County Schools, is only mid-tier, ranking in the 45th percentile of Tennessee districts. The school dramatically outperforms both its district and the state on every TNReady subject, averaging roughly 82% proficiency across Algebra I, Algebra II, Biology I, US History, English I, English II, and Geometry—compared to about 43% statewide. Its smallest edge is in Algebra I (54.7% proficient), but that is still more than 20 points above the state average. Graduation and engagement are equally impressive: the graduation rate is 97.6% (vs. 90.5% statewide), the dropout rate is just 2.4%, and chronic absenteeism is only 10.6%—well below the state’s 18.3%.
The school also shows strong momentum. From 2024–2025 to 2025–2026, Algebra I proficiency jumped from 26.7% to 54.7%, and Geometry rose from 72.6% to 83.4%, with gains in nearly every subject. While test results vary by grade and course timing, the school’s excellence is consistent across STEM and humanities alike. One caveat: free/reduced-price lunch percentage and student/teacher ratio were not reported, so full socioeconomic and class-size context is unavailable. Still, by every available measure, L N STEM Academy is an exceptional choice and, without question, the standout high school in zip code 37902.
