High Schools in DeKalb County

Lakeside High School is one of 23 high schools in DeKalb County, a diverse suburban district east of Atlanta serving grades 9-12, with enrollment ranging from 167 students at Elizabeth Andrews High School to 2,234 at Lakeside.

The district's clear academic leaders are its specialized schools. Dekalb Early College Academy ranks 4th in the state with a 100% graduation rate, 86.7% Algebra I proficiency, and just 3.9% chronic absenteeism—the lowest in the district. DeKalb School of the Arts follows at 24th statewide with 92.2% US History proficiency. Among traditional schools, Chamblee High School leads at 80th in the state, exceeding state averages in Biology and US History. Arabia Mountain High School is a standout success story, achieving a 100% graduation rate and above-state-average Algebra I proficiency despite 65.2% economic disadvantage. The most dramatic improvement comes from Clarkston High School, which jumped 176 positions in state ranking, while Stephenson High School and Lithonia High School also show strong upward momentum.

At the other end, Elizabeth Andrews High School faces the greatest challenges with a 45.1% graduation rate, 61% chronic absenteeism, and single-digit test proficiency. Stone Mountain High School and Cedar Grove High School also rank in the bottom quartile. District-wide, chronic absenteeism averages 26.7% versus the state's 17.7%, and 19 of 23 schools fall below the state average in Algebra I. However, Biology shows the smallest gap, with several schools exceeding state averages. The district's dropout rate of 4.4% is nearly double the state average, though Dunwoody High School (1.7%) and Stephenson (2.9%) demonstrate lower rates are achievable. Notably, Dunwoody has slipped 66 positions in state ranking, warranting attention despite its relatively low economic disadvantage.
