On September 29, 2025, at a ceremony held at Lithonia High School, DeKalb County^↗ET officials celebrated a milestone: for the first time in district history, the four-year graduation rate had crossed 80%. Eighteen of 23 high schools improved. Four posted perfect 100% rates. Superintendent Devon Horton called the results proof of "what's possible when we stay focused on every student, every day."

Sixteen days later, the DeKalb County Board of Education voted 6-1 to accept Horton's resignation after a federal grand jury indicted him on charges of accepting kickbacks during his previous superintendency in Illinois. He was DeKalb's ninth superintendent since 2010.

That sequence captures the district's central tension. DeKalb County has made real, measurable progress. Its graduation rate climbed from 58.6% to 81.6% over 14 years, a 23-point gain. But the district has done so while lurching through governance crises, accreditation warnings, and a superintendent revolving door that has denied it the sustained leadership its peers enjoyed. At 81.6%, DeKalb trails Gwinnett County^↗ET by 3.8 points, Clayton County^↗ET by 4.7 points, Cobb County^↗ET by 7.6 points, Atlanta Public Schools^↗ET by 8.9 points, and Fulton County^↗ET by 10.3 points. It is the only major metro Atlanta district below the state average of 87.2%.

The stall that cost five years

DeKalb's trajectory breaks into three distinct chapters. From 2011 to 2018, the rate climbed steadily from 58.6% to 75.0%, including a large methodology-influenced jump in 2015. Then progress stopped. Between 2019 and 2023, the graduation rate hovered in a narrow band of 73.4% to 76.2%, never deviating more than 2.6 points from its five-year average. While DeKalb flatlined, the state average rose from 82.0% to 84.4%. The gap, which had narrowed to 6.6 points in 2017-2018, ballooned back to 8.6 points by 2019 and stayed there through 2023.

The stall coincided with the district's most chaotic period of leadership turnover. Steve Green was fired in late 2019. Ramona Tyson was named interim, then permanent, then retired within months. Cheryl Watson-Harris arrived during the pandemic and departed amid controversy over deteriorating building conditions at Druid Hills High School. Vasanne Tinsley served as interim. Horton arrived in July 2023 and left two years later.

The recent breakout has been genuine. DeKalb gained 3.3 points in 2024 and another 2.6 in 2025, a combined 5.8-point improvement that erased the stall-era stagnation. Elizabeth Andrews High School jumped 28.8 points in a single year. Cross Keys High School, which serves a heavily immigrant community in Chamblee, gained 9.4 points and now meets criteria for removal from the federal Comprehensive Support and Improvement list.

Clayton County's lesson

The most instructive comparison is not with Fulton or Cobb, wealthier districts with structural advantages, but with Clayton County^↗ET, which shares DeKalb's demographic profile. Both districts are majority Black. Both serve predominantly low-income families. Both started the period at the bottom of metro Atlanta's rankings.

In 2011, Clayton's graduation rate was 51.5%, seven points below DeKalb's 58.6%. By 2020, the two had converged at roughly 76%. Then they diverged. Clayton climbed steadily through the pandemic years, from 76.6% to 86.3% by 2025, a 34.8-point total gain. DeKalb stalled.

The difference is not demographics. Clayton's Black graduation rate reached 87.1% in 2025; DeKalb's reached 83.5%. Clayton's Hispanic rate hit 85.0%; DeKalb's hit 71.1%. Clayton's economically disadvantaged rate matched its overall rate at 86.3%; DeKalb's lagged at 80.9%.

Clayton County's superintendent, Dr. Anthony Smith, has led the district since 2020, providing five years of continuous leadership. Under Smith, Clayton expanded credit recovery through satellite sites at four high schools, paired at-risk students with dedicated mentors, and built career pathway programs through Perry Career Academy. The district set a public target of 90% by 2026 and has tracked steadily toward it.

DeKalb, over the same period, cycled through three permanent and two interim superintendents. Each brought new initiatives. None stayed long enough to see them through.

The district within the district

DeKalb's 81.6% overall rate masks a widening internal gap. The district's white students graduate at 91.6%, above the state average. Black students, who make up 59.2% of the senior cohort, graduate at 83.5%. Hispanic students, now 21.7% of the cohort and growing, graduate at 71.1%, 10.5 points below the district average and 16.1 points below the state.

The Hispanic cohort has grown from 586 students in 2011 to 1,506 in 2025, a 157% increase. That growth has not been matched by proportional graduation gains. Hispanic students in DeKalb improved from 46.8% to 71.1%, a 24.3-point gain that sounds substantial until measured against Clayton County's Hispanic rate of 85.0%, or against the fact that DeKalb's Hispanic rate in 2023 was still just 60.7%. The 10.4-point jump over the last two years is encouraging but follows a decade of stagnation.

DeKalb has recognized the challenge. In June 2025, the district published an English Learners Master Plan that tracks graduation rates by English proficiency level and establishes intervention protocols for students at risk of aging out without a diploma.

Students receiving special education services improved the most in percentage terms, from 23.1% in 2011 to 72.3% in 2025, a 49.2-point gain that Horton's office described as an eight-year upward trend exceeding 28 points. But that subgroup, 828 students in 2025, still graduates at 9.3 points below the district average.

Momentum without a leader

The immediate question for DeKalb is whether a district that has gained nearly six points in two years can sustain that trajectory under its tenth superintendent search since 2010.

"As graduation rates rise, more students aren't ready for what comes next." -- WSB-TV, September 2025

That statewide concern applies with particular force in DeKalb, where the $200 million capital shortfall confirmed by the school board in December 2024 will constrain the next superintendent's ability to invest in the facilities and programs that underpin graduation support. The district credited its recent gains to a "Post-Secondary Push Plan" built on monthly graduation monitoring meetings, dedicated support staff, and Horton's "Four E's" framework: enlistment, employment, entrepreneurship, or enrollment after graduation. Whether that infrastructure survives the transition to acting superintendent Norman Sauce III and then a permanent hire is not guaranteed.

In 2011, DeKalb County did not graduate 3,378 of its 8,169 seniors. In 2025, that number fell to 1,274 of 6,940, a reduction of more than 2,100 students per year who leave with a diploma instead of without one. That progress is real, and it happened despite conditions that would have broken less resilient school communities. The question is not whether DeKalb has improved. It has, unambiguously. The question is why it took five years longer than Clayton County to start improving again, and whether the answer, a revolving door at the top, is about to repeat itself.
