Correction (September 19, 2026): An earlier version of this article gave Joplin's 2022 graduation rate as 80.5% and its 2023 rate as 84.3%. The state's data show 81.9% and 84.4%. The earlier version also called Joplin's gain one of the largest turnarounds in Missouri and Joplin one of the state's highest-performing mid-size districts without measuring either. It now reports the measured comparison. A passage attributing the turnaround to the district's recovery from the 2011 tornado, which cited a casualty figure without a source, has been removed.

Joplin Schools^↗ET was heading in the wrong direction. The district's four-year graduation rate fell from 83.9 percent in 2019 to 80.2 percent in 2020 to 75.1 percent in 2021.

Then it turned. Joplin's rate climbed to 81.9 percent in 2022, then 84.4 in 2023, then 88.0 in 2024, and finally 96.5 percent in 2025. The 21.3 percentage point gain from 2021 to 2025 was the largest of any Missouri district with at least 300 students in both of those graduating classes, a group of 56 districts.

The 2025 leap

The largest single-year gain came in 2025, when Joplin's rate rose 8.4 percentage points. In a 509-student cohort, that is roughly 43 more students graduating on time than the prior year's rate would have produced.

Single-year gains of that size can reflect changes in how a cohort is counted or an unusual class. Joplin's 2025 gain followed three straight years of increases, which makes it part of a longer climb rather than a one-year spike. The records do not identify what produced it.

From below average to above

In 2021, Joplin's graduation rate trailed the state average by 15.5 percentage points. By 2025, Joplin had closed that gap and passed it, finishing 3.8 points above the statewide rate of 92.7 percent.

Scale matters

Joplin's 509-student cohort is large enough to make the improvement meaningful. It is not a small district where five or ten students shift the rate by double digits. The rate rose every year from 2021 to 2025.

Where it leaves Joplin

At 96.5 percent, 18 students in Joplin's 2025 cohort of 509 did not graduate on time. In 2021 the district graduated three of every four students in its cohort; in 2025 it graduated all but a handful. The graduation records establish that change. They do not explain it.

Graduation rates and cohort counts come from the Missouri Department of Elementary and Secondary Education's four-year adjusted cohort graduation data.
