When Ryan Nielsen's fleet of yellow school buses picked up their first loads of students in the fall, the Canby superintendent's transportation department was paying about $2.60 per gallon to refuel.
By spring, the average price of diesel in the western Minnesota district, which enrolls about 567 students, was about $4.39 a gallon.
"When you're buying 5,000 gallons at a time, that adds up in a hurry," Nielsen said. "It cuts into our bottom line."
As Americans grapple with rates of inflation unseen since the 1980s, increased costs are taking a toll on Minnesota's public schools. District leaders say that in addition to the increased costs for fuel and groceries, supply-chain disruptions are also causing headaches for department heads.
In the Anoka-Hennepin school district, officials say they can't offer tater tot hot dish because of how much more it costs to purchase the ingredients. Osseo district officials say they've similarly had to alter their menus, an exercise familiar to families who have seen the price for a carton of eggs nearly double over the last year.
"It's costing more for all of us to live. And operating our schools is costing more," Osseo Superintendent Cory McIntyre said.
The same supply-chain issues have drastically slowed down progress on several projects in the St. Paul district.
While soaring costs for construction material and electrical gear mean it's getting more expensive for homeowners to redo their kitchens or track down the latest gaming console, the supply crunch means some St. Paul schools have deferred their roof maintenance schedules by 10 to 11 months.
