Best Public Schools in Corryton, TN

Corryton, Tennessee, is served by four public schools within the Knox County Schools district, covering elementary through high school with two elementary schools, one middle school, and one high school. Overall, Corryton’s schools outpace state averages in early academics, but face growing challenges with attendance and math proficiency as students advance. Corryton Elementary School is the standout performer, ranking in the 78th percentile statewide with 65% ELA and 60.2% math proficiency, both well above district and state averages, and it also has the lowest chronic absenteeism at 11.3%. Despite being the smallest school, it spends the most per student at $15,264. Gibbs Elementary School is much larger with 966 students and remains above district averages, but its state ranking has slipped from the 77th to 67th percentile over three years, with math proficiency dropping from 56.6% to 52.6%.

At the middle and high school level, Gibbs Middle School shows a striking split: its advanced Algebra I students post an extraordinary 77.8% proficiency rate, yet overall math proficiency is just 31.9%, well below district and state averages, and ELA proficiency sits at 36.9%. The school also has a 20.9% chronic absenteeism rate. Gibbs High School has improved its state ranking from the 40th to 60th percentile in one year, with large gains in Geometry, Algebra II, US History, and English II. However, it still trails the district in key subjects like English I and Algebra I, and its chronic absenteeism rate of 24.8%, graduation rate of 88.9%, and dropout rate of 7.9% are all worse than district and state averages.

The clearest pattern is that chronic absenteeism rises with grade level, from 11.3% at Corryton Elementary to 24.8% at Gibbs High, which likely contributes to lower graduation rates and weaker outcomes. Another notable trend is that elementary math proficiency is strong across Corryton, but middle school math collapses dramatically, suggesting a difficult transition. The most promising outlook is at Corryton Elementary, where small size and higher spending coincide with exceptional third-grade results, while Gibbs Middle’s advanced math track and Gibbs High’s rapid test-score improvements show that targeted progress is possible.
