The district began a four school day per week schedule in 2024, and at the time it was the largest school district in Idaho to do so. Circa 2004, the district had all of its high schools operate on a semester system, with eight classes at a time. Classes were held on alternating A and B days. In 2024, the school district moved to a trimester system. Haadiya Tariq of the Idaho Press wrote that, citing these choices and the school closures, this became "a difficult 2023-2024 school year full of hard decisions".
