For 16 of the past 17 years, North Dakota's public school enrollment went in one direction: up. The Bakken oil boom pulled families into the western prairie. Fargo's suburbs sprawled east. The state added 23,192 students between 2009 and 2025, a 24.8% surge that made North Dakota one of the fastest-growing states for K-12 enrollment in the country. Last year, the system added 831 students. A slower year, sure, but still growth.

Then the North Dakota Department of Public Instruction published its 2025-26 School Finance Facts, and the number that came back was 116,365. Down 233 from 116,598. The only other decline since 2009 came during the pandemic year of 2021. This one has no pandemic to blame.

Last year's slowdown was not a pause. It was the leading edge.

What the numbers open up

The data file covers all 165 North Dakota school districts, broken down by grade level from kindergarten through 12th grade. Over the coming weeks, The NDEdTribune will unpack it in a multipart series. Here is what we are looking at first.

The growth era is over. Annual gains shrank from +2,016 in 2020 to +382 in 2024 to -233 in 2026. The deceleration pattern has been visible for years, but the first actual decline makes it official. The state now sits 6,336 students below where its pre-COVID growth trajectory projected it would be — a gap worth $71.9 million in per-pupil funding.

Kindergarten is collapsing. North Dakota enrolled 8,361 kindergartners in 2025-26 and 8,400 twelfth-graders. The entering class is now smaller than the exiting one for the first time since 2010. Kindergarten has fallen 13.1% from its 2020 peak of 9,620, and the state's birth numbers say smaller cohorts are still coming.

By the numbers: 116,365 students statewide in 2025-26 — down 233 from the prior year, ending a 16-year growth streak driven by the Bakken oil boom.

The threads we are following

West Fargo's 18-year machine. While the state declined, West Fargo Schools grew for the 18th consecutive year, more than doubling from 6,179 to 13,211 students since 2008. The district overtook Fargo in 2021 and is now just 466 students behind Bismarck. At its current pace, West Fargo becomes North Dakota's largest district by 2028.

The graduation rate collapse. North Dakota's four-year graduation rate has dropped from 89% to 82.4% in four years. That is 6.6 percentage points lost, and the decline is accelerating. Native American students graduate at 63.4%, a 24-point gap with white students that has widened after six years of slow progress.

Two North Dakotas. The state's 165 districts are splitting into two states: 25 districts sit at all-time enrollment highs while 24 sit at all-time lows. The winners cluster in the oil patch and Fargo-Bismarck suburbs. The losers are the rural and reservation communities that have been losing students for a generation.

What comes next

Each of these threads will get its own article with charts, district-level breakdowns, and context. The first deep dive will focus on the statewide enrollment reversal — the story that frames everything else. New articles publish every Thursday.
