The 1920s in America was a decade of vast economic growth. The labor shortage and need for increased production during WWI fueled a need for more efficient production methods. Technology improved standardized mass production with better machinery in factories, causing higher productivity and wages, stimulating demand for goods.
By 1923 classes included mechanical drawing and shop arithmetic, carpentry, sheet metal, millinery, cooking, sewing, letter writing, spelling, hygiene, citizenship, accounting, secretarial practices, office machines, academic work, and telegraphy. Chippewa Falls ran a separate machine shop behind the old high school.
That decade classes were added in home nursing, salesmanship, commercial law, agriculture lab, elements of banking, physical culture for girls, English for new Americans, papermaking, industrial safety, and agriculture, and a coordination program began for rehabilitation education. Eau Claire was among the first cities in the state to have daytime industrial classes.
