Correction (July 20, 2026): This article was rebuilt after the 2026 graduation report became available. The earlier draft ended with 2025 and described a widening gap. The current data show that the gap narrowed sharply in 2026. The headline, figures, district comparisons, charts and interpretation have been corrected.

A 16-district panel drawn from district names that reference Delta counties averaged an 88.7% graduation rate in 2026. The other 125 districts in the state data averaged 90.2%, leaving a 1.5-percentage-point gap.

That was a sharp reversal from 2025, when the panel averaged 83.6% and other districts averaged 88.5%. The panel's mean rose 5.1 points in one year, compared with 1.7 points elsewhere, narrowing the gap by 3.4 points.

Fifteen of 16 districts improved

The latest increase was broad within the comparable panel. Fifteen of the 16 districts reported a higher rate in 2026 than in 2025.

North Panola^↗ET posted the largest gain, rising 11.7 points from 78.0% to 89.7%. Greenwood-Leflore rose 9.7 points to 92.3%, and Quitman County rose 8.3 points to 93.7%.

Sunflower County Consolidated was the only panel district to decline, slipping 0.7 points from 85.1% to 84.4%.

The long view still shows a smaller gap

The panel's unweighted district mean was 65.7% in 2014, compared with 74.8% for other districts, a 9.1-point difference. By 2021, those means were 87.0% and 87.3%, respectively, leaving a gap of only 0.3 points.

The difference widened again to 4.9 points in 2025 before returning to 1.5 points in 2026.

Across the full available span, the panel mean rose 23.0 points while the other-district mean rose 15.4 points. The gap in the yearly means narrowed by 7.6 points from 2014 to 2026.

The source has no 2020 graduation report. Panel membership also ranges from 14 to 17 districts across the history as district names, consolidations and reported coverage change. The long-run comparison therefore describes each year's reported group rather than a fixed cohort of identical districts.

A wide range remains inside the panel

Eight of the 16 panel districts reported 2026 graduation rates of at least 90%. Coahoma County^↗ET was highest at 97.3%, followed by South Panola^↗ET and Quitman School District at 95.7% each.

Two districts remained below 80%: Yazoo City at 72.4% and North Bolivar at 79.4%. The distance between the panel's highest and lowest rates was 24.9 points.

What this comparison measures

The Mississippi graduation files do not label districts by region. This analysis applies a reproducible name screen: a district enters the panel when its reported name contains Bolivar, Coahoma, Humphreys, Leflore, Quitman, Sunflower, Tallahatchie, Tunica, Washington, Yazoo, Sharkey, Holmes or Panola.

That makes the panel narrower than a geographic census of every school district commonly described as part of the Delta. It should be read as an operational comparison, not as an official regional classification.

The headline figures give every district equal weight. A sensitivity check using reported 2026 cohort counts produced a similar result: 89.0% for the panel and 90.9% for other districts, a 2.0-point gap after calculating from the unrounded rates.

The files establish how the reported rates changed. They do not identify the district policies, student circumstances or reporting factors that caused those changes.

This analysis uses Mississippi Department of Education district graduation rates for 2014 through 2019 and 2021 through 2026. The department publishes the latest graduation tables through its 2026 accountability reporting page. District means in this article are unweighted unless otherwise noted.
