for only one year. That same year the school's programs were expanded and authorization was given to award baccalaureate teaching degrees. This led to an institutional name change the following year to La Crosse State Teachers College. In 1931, the college was divided into separate elementary education, secondary education, and physical education divisions. It was also this year that the homecoming tradition of the "Hanging of the Lantern" began at the south entrance of Maurice O. Graff Main Hall. It was created by English teacher Orris O. White who remarked, "We'll hang the lantern in the old college tower... You won't need to look for the key – the door will be open." The Training School, which had also been referred to as the Campus School and the Model School, moved into its newly constructed building in 1939.
