Summary
Gibbs High School is a comprehensive public high school in Corryton, TN, serving 1,029 students in grades 9–12 as part of Knox County Schools. In 2025–26, Gibbs ranked 159th out of 400 Tennessee high schools, placing it in the 60th percentile with a 3-star rating — a strong climb from 206th the prior year and 237th in 2023–24. The school also outperforms its district's overall ranking of 78th among 141 districts, and stands as the highest-ranked traditional zoned high school in the area, ahead of Halls High School, Central High School, and Union County High School.
Gibbs's biggest academic story is recent momentum in math and science. Geometry proficiency more than doubled to 46.6%, now above both state and district averages, and Algebra II improved from 11.5% to 34.0%. Biology I is a clear strength at 53.9% proficiency, and 10th-grade Biology scores are especially impressive at 78.5% — far above the state's 41.3%. Gibbs even outpaces Career Magnet Academy in Algebra I (25.8% vs. 21.1%) and Geometry (46.6% vs. 44.4%), though Career Magnet leads significantly in English. On the flip side, Algebra I, English I, and US History remain below state averages and are clear priority areas.
Equally encouraging is how well Gibbs serves historically underserved students. Low-socioeconomic-status students scored at the 75th percentile statewide in 2025–26, up sharply from the 39th percentile the prior year, while African American, Hispanic, and Special Education students all posted significant gains. The school's main challenges are engagement-related: chronic absenteeism is 24.8% versus 18.3% statewide, the dropout rate of 7.9% exceeds the 6.7% state average, and the graduation rate of 88.9% trails the 90.5% state figure. Gibbs spends about $13,296 per student — comparable to nearby Halls and Central but far less than alternative schools — which points to efficient use of resources. If Gibbs can translate its academic momentum into better attendance and graduation outcomes, it is well-positioned to keep climbing the statewide rankings.
