Missouri leads the nation in four-day school weeks. This map shows the year each district adopted the schedule — more than a decade of spread across the state, concentrated in rural Missouri and now reaching larger districts.
What this page shows
185 districts were on a four-day week in 2025–26 — and 176 of them are rural. Almost everything that looks like a “four-day effect” is partly a rural effect.
Statewide, four-day districts pay $4,192 less at the median. Compare them only to their rural five-day neighbors and the gap collapses to $1,024 — and starting pay is $40,000 in both.
It was never a budget cut. Four-day districts spend no less per pupil than their rural five-day peers — slightly more, in fact.

ADOPTION BY YEAR
When each district made the switch
Color marks the year a district adopted the four-day calendar — from a handful of early adopters to the surge that followed the pandemic and Senate Bill 727.

Statewide, four-day districts pay less at every step of the master’s-degree lane, and the gap grows with experience. But most four-day districts are rural — and rural Missouri pays less everywhere. Flip the switch and watch what happens to the gap when you compare rural districts only.

Medians of district salary schedules from the MNEA 2025–26 salary report — 472 districts report a master’s lane (347 rural). Starting pay on the BA lane is $40,000 in nearly every district under the teacher baseline salary grant. These figures describe published schedules, not individual teachers, and imply nothing causal about the four-day calendar itself.
THE THREE COMPARISONS
Four-day and five-day Missouri, side by side
The three maps below all carry the same control: a Week Length filter in the top corner. Untick a box and half the state disappears — which is the fastest way to see that four-day Missouri and rural Missouri are very nearly the same map. Each comparison below is reported two ways: statewide, and then against rural five-day districts only. The second number is the honest one.

PAY
The four-day pay gap is mostly a rural pay gap
Average teacher salary, 2025. Use the Week Length filter to show four-day districts alone, five-day alone, or both.
Statewide, four-day districts pay a median $46,318 against $50,510 — $4,192 less. That number gets quoted a lot. But compare four-day districts only to their rural five-day neighbors and the gap collapses to $1,024 — about 2.2%. The schedule maximum tells the same story: 9.6% lower statewide, 1.4% lower against rural peers. And the bottom of the ladder is identical — $40,000 to start in both, because the state’s baseline salary grant lifted the entry step everywhere.
Four-day schools do not underpay for their geography. Rural Missouri underpays everywhere — and what remains of the four-day gap sits at the top of the schedule, not the bottom, which is where a district loses its most experienced teachers.
Average teacher salary by district, 2025 (DESE). Darker = higher pay. Medians: four-day $46,216, five-day $50,416; among rural districts only, $46,029 vs $47,192.
ENROLLMENT
Shrinking faster — even among their own neighbors
Enrollment change, 2010 to 2025. Blue is growth, red is decline.
Among rural districts, four-day schools lost 15.9% of their enrollment at the median; rural five-day schools lost 12.6%. This is the one gap that survives the rural control and grows under it — four-day districts are shrinking faster than the rural districts right next door.
Read that in the right direction. The four-day week is a schedule districts reach for when they are losing children and cannot compete for teachers — not a schedule that drives families away. Adoption follows hardship. These data can establish that the two travel together; they cannot establish which one moved first, and we do not claim they can.
Percent change in enrollment, 2010–2025 (DESE). Centered at zero: blue = growth, red = decline. One caution at the top of the scale — Sturgeon R-V shows +554%, an artifact of the statewide virtual school it hosts, not local growth.
SPENDING
It was never about the money
Current per-pupil spending, 2025. Darker = higher spending.
Four-day districts spend slightly more per pupil than their rural five-day peers — $13,454 against $13,351. The margin is small, and the honest way to say it is that four-day districts spend no less. Their levy effort is a shade higher too. Whatever the four-day week is doing in Missouri, it is not functioning as a budget cut, and districts that adopt it are not the ones taxing themselves least.
This matches the national research, which has consistently found savings of roughly 1–2% at most — a rounding error in a school budget. When districts explain the switch, they tend to talk about recruiting teachers they otherwise could not hire. The pay map above is the reason why.
Current per-pupil spending by district, 2025 (DESE). Medians among rural districts: four-day $13,539, five-day $13,280.
A word on what these three maps can and cannot tell you. Districts choose the four-day week; it is not assigned at random. The districts that choose it are, on average, the smallest, the most rural, the fastest-shrinking and the hardest-pressed to hire — and those things shape outcomes on their own. Any difference you see here therefore describes who adopts the schedule, at least as much as what the schedule does. Read them as a portrait of the districts, not as a verdict on the calendar.
