In this series: Oklahoma 2025-26 Enrollment.

A year ago, Oklahoma's enrollment dip looked manageable. The state lost 1,744 students, a 0.25% decline, the kind of number that barely registers in a state with nearly 700,000 public school students. Some districts grew. The post-COVID recovery had clawed back three-quarters of the pandemic losses. Administrators talked about stabilization.

Then the Oklahoma State Department of Education published its 2025-26 enrollment figures, and stabilization evaporated: 686,718 public school students, down 10,640 from the prior year. That is the largest single-year loss in the state's enrollment dataset — larger than the 9,537-student drop during COVID. Oklahoma is now at the lowest enrollment recorded since at least 2015-16, and 7,395 students below the pandemic floor it hit in 2021. Whatever floor people thought they saw last year was not a floor.

What the numbers open up

The enrollment data covers roughly 540 districts, from the state's largest urban systems to micro-districts with fewer than 100 students. Over the coming weeks, The OKEdTribune will unpack it in a series of data-driven articles. Here is what jumps out first.

Epic Charter's rise, scandal, and collapse. In 2016, Epic Charter Schools enrolled 6,037 students. Five years later it enrolled 59,445, more than any district in state history. Then came the racketeering charges, 500 layoffs, and a collapse to 29,201. The ripple effects reshaped the entire state's enrollment picture — and they are still playing out.

Oklahoma City lost nearly a third of its students. OKCPS dropped from 45,577 to 31,104 students in a decade, a 31.8% decline. It lost its No. 1 ranking to Tulsa, closed 32 campuses, and watched suburban neighbors like Deer Creek and Piedmont grow by 40-50%. The loss at the center is larger than the state's entire net enrollment decline.

More students left this year than during COVID. The 10,640-student cliff of 2025-26 exceeds the pandemic loss by 1,103 students. There is no pandemic this time. The three-year post-recovery slide has erased 14,540 students — more than 1.5 times the original COVID hit.

By the numbers: 686,718 students statewide in 2025-26 — down 10,640 from the prior year, a 1.5% decline, the largest single-year loss on record, and a new all-time low.

The threads we are following

187 districts just hit all-time lows. More than a third of Oklahoma's districts with five or more years of data are at the lowest enrollment ever recorded. That includes both Oklahoma City and Tulsa.

Fewer kindergartners than seniors for the first time. Oklahoma's kindergarten class fell 14.5% over the past decade while the senior class grew 17.0%. The K-to-12th grade ratio dropped below 1.0 for the first time — a pipeline inversion that signals years of further decline ahead.

36 districts have fewer than 100 students. Oklahoma's micro-district landscape is fragile. One bad year can threaten the viability of a district that serves an entire rural community.

What comes next

Each of these threads will get its own article with charts, district-level breakdowns, and context. New articles publish Wednesdays. The first deep dive, next week, looks at how a single virtual charter school reshaped the entire state's enrollment picture.

The enrollment figures come from the Oklahoma State Department of Education enrollment portal. The data covers the October 1 headcount for public school districts statewide.
