Georgia's Special Ed Graduation Rate Has More Than Doubled

Thu, 28 May 2026 12:00:00 GMT

In 2011, Bibb County graduated 9.2% of its students with disabilities. Nine out of every hundred seniors with an IEP walked across a stage in Macon. The other 91 did not.

Last year, Bibb graduated 84.5%. That is a 75.3 percentage point swing in 14 years, in a district where more than 200 students with disabilities enter the graduation cohort each year. The senior with a disability in Macon today has roughly the same odds of graduating as the average Georgia student did a decade ago.

Bibb is the sharpest version of a statewide transformation. Georgia's four-year adjusted cohort graduation rate for students with disabilities rose from 29.8% in 2011 to 78.4% in 2025, a 48.6 percentage point gain that more than doubled the rate. No other subgroup comes close. Black students gained 26.9 points. Economically disadvantaged students gained 26.6. Hispanic students gained 24.7. Special education's improvement is nearly twice the next-largest gain, and it produced 10,518 additional graduates per year: 14,708 in 2025 compared to 4,190 in 2011.

42 points to 10

The gap between students with disabilities and their non-disabled peers was 42.2 percentage points in 2011. By 2025, it had narrowed to 10.2 points. The non-disabled rate climbed too, from 72.0% to 88.6%, a 16.6-point gain. But special education's rate climbed three times faster, cutting the distance by 32 points.

The trajectory has two distinct phases. From 2011 to 2014, the special education rate inched from 29.8% to 36.5%, gaining roughly 2.2 points per year. Then 2015 arrived with a 17.8-point jump to 54.3%, an increase so large it demands scrutiny. A methodology change that year in how Georgia calculated cohort membership for students with disabilities, combined with expanded credential pathways, almost certainly accounts for a significant portion of that single-year leap. The overall state rate also jumped 6.2 points that year.

But what happened after 2015 is harder to dismiss as an artifact. From 2015 to 2025, the special education rate gained another 24.1 points at a pace of 2.4 points per year, steady and sustained. That post-methodology-change climb is real instructional progress: it happened while the cohort grew by 37.5%, from 13,654 students to 18,770. Georgia is graduating more students with disabilities at a higher rate from a larger cohort.

What 10,518 additional diplomas look like

The raw numbers reframe the achievement. In 2011, 9,851 students with disabilities in the graduation cohort did not earn a diploma. In 2025, that number is 4,062, despite the cohort growing by a third. Georgia cut the number of non-graduating students with disabilities by 59% while simultaneously expanding who gets counted.

That expansion matters. Students with disabilities made up 10.7% of the 2011 cohort and 13.2% in 2025. Some of that increase likely reflects broader identification of disabilities, a national trend that saw IDEA-eligible student counts rise 3.8% in 2024 alone. More students are being identified, and more of those identified students are graduating.

The cohort growth also means the improvement is not merely a story about reclassification pushing marginal students out of the special education category. If districts were graduating more students with disabilities primarily by exiting them from special education before senior year, the cohort would have shrunk, not grown.

The districts that moved farthest

Atlanta Public Schools went from 12.9% to 83.1%, a 70.2-point gain. Carroll County went from 23.6% to 94.3%. Haralson County, a small rural district northwest of Atlanta, went from 23.2% to 94.4%. Troup County, on the Alabama border, went from 17.3% to 84.0%.

These are not small cohorts producing volatile rates. Atlanta had 497 students with disabilities in its 2025 graduation cohort. Bibb had 206. Carroll County had 124. Muscogee County, home to Columbus, improved from 27.5% to 89.5% with a cohort of 304.

At the top of the 2025 leaderboard, three districts with cohorts of at least 20 posted 100% special education graduation rates: Brooks County (26 students), Union County (32), and Vidalia City (22). Oconee County graduated 68 of 69 students with disabilities for a 98.6% rate. McDuffie County graduated 45 of 46 for 97.8%. Statewide, 37 districts with at least 20 students in the cohort posted special education graduation rates at or above 90%.

In Bibb County, the improvement has been deliberate.

"It's been a steady push at the school level. The district started tracking all students' course grades monthly and providing developing plans for kids that were falling behind, and trying to get contact with families." -- The Macon Newsroom, 2024

Jennifer Donnelly, executive director of Bibb's program for exceptional children, described a system of monthly grade monitoring and intervention plans for students falling behind. It is a labor-intensive approach. It is also, based on Bibb's trajectory, an effective one: the district's special education rate rose from 39.3% in 2016 to 84.5% in 2025, gaining more than 45 points in nine years.

The funding arithmetic behind the gains

Georgia funds special education through a weighted formula that assigns students to five tiers based on instructional intensity. The most resource-intensive tier, Category IV, carries a per-pupil cost of $16,371, roughly four times the base funding amount. Category I students cost $6,726 per pupil. Those weights have remained essentially unchanged since 2006, even as the number of students receiving services has grown.

The Georgia Budget and Policy Institute estimates 215,000 K-12 students received special education services in 2021-22, representing 8.7% of the school-age population, below the national median of 9.6%. Georgia also places a smaller share of its students with disabilities in general education classrooms: 62% spend more than 80% of their day in regular settings, compared to 68.4% nationally. That gap represents roughly 8,000 students who, in the median state, would be learning alongside their non-disabled peers.

The graduation gains, then, occurred despite relatively conservative placement practices and stagnant funding weights. What changed was not the formula. It was the expectation.

The virtual school problem

The statewide 78.4% rate, encouraging as it is, masks an internal divide. Traditional school districts have driven the improvement. Virtual and alternative charter schools have not kept pace.

Georgia Cyber Academy graduated 60.8% of its students with disabilities in 2025. Georgia Connections Academy graduated 59.6%. Both serve substantial cohorts: 102 and 156 students respectively. Three alternative completion charters, which serve students who previously dropped out and returned to earn a diploma, posted rates far lower: Foothills Charter at 10.8% (203 students), Mountain Education at 11.2% (197), and Coastal Plains at 15.7% (140).

These schools serve fundamentally different student populations, and a direct comparison is not entirely fair. The alternative completion schools, which hold classes at night and on weekends, enroll students who have already left traditional schools. Their low graduation rates partly reflect the difficulty of re-engaging students who have already disengaged once. Still, 540 students with disabilities entered those three alternative programs in 2025. Only 66 graduated. That is a pipeline worth examining.

The Georgia State Charter Schools Commission uses a comprehensive performance framework to evaluate charter outcomes, and has conducted specific studies of virtual school performance. Whether those evaluations have produced meaningful accountability for special education outcomes is less clear.

What this rate does not measure

A diploma is a necessary credential. It is not sufficient evidence of preparation. Georgia's Milestones assessment data tells a harder story: in 2021, 61% of students with disabilities scored at the lowest performance level ("beginning"), compared to 20.6% of non-disabled students. The graduation rate measures completion. It does not measure what was learned along the way.

There is also the question of whether rising identification rates have shifted the composition of who counts as a student with disabilities. If more students with mild learning differences are being identified, the graduating cohort becomes, on average, less disabled. That would mechanically improve the rate without changing outcomes for students with more significant needs. The data does not allow this to be tested directly. But the national trend toward broader identification is well documented, and Georgia's cohort growth of 33.7% over 14 years is consistent with it.

The 10-point question

The remaining 10.2-point gap between students with and without disabilities is the smallest on record. Closing it further will be harder. The gains from expanded credential pathways and the 2015 methodology change have already been captured. What remains is the structural gap: the students whose disabilities most directly interfere with coursework completion, the districts that have not invested in the monthly tracking and intervention that Bibb County adopted, and the virtual schools where students with disabilities are graduating at rates that traditional districts left behind a decade ago.

The Class of 2025 produced 14,708 graduates with disabilities, 3.5 times the number in 2011. That is 14,708 credentials in 14,708 hands. Whether the preparation behind those credentials matches the credential itself is a question Georgia's assessment data will eventually have to answer.
