A graded school was any school with more than one room and thus more than one grade level of pupils. McAllister State Graded School was built in 1914 and expanded in 1919, 1924, and 1936 in response to the state government's encouragement of state graded schools to improve the quality of rural education. In the early twentieth century, Marinette County had many one-room schools but only three two-room state graded schools. The building was purchased by the Town of Wagner for use as a Town Hall in 1957.
