From 1908 to 1960, the South Dakota School of Agriculture at Brookings provided practical, vocational education to young men and women across South Dakota. Operating on the campus of South Dakota tate College, the school offered a five-month academic year focused on vocational agriculture and home economics, while still including standard subjects such as English and arithmetic. Students, known as Aggies, participated in extracurricular activities, including publishing a school newspaper, and often balanced their education with work or family responsibilities during the remaining seven months of the year.
In its early years, the school attracted strong enrollment from rural students, many of whom were older than traditional high school age and lacked access to nearby secondary schools. The short academic term and residential model appealed to students who lived far from established public high schools.
The passage of the Smith-Hughes Act of 1917, which funded vocational programs in public schools, contributed to a gradual decline in enrollment. The establishment of more high schools throughout South Dakota further reduced the demand for the School of Agriculture. In the post-World War II era, the school shifted focus to offering agricultural certificates akin to associate degrees. By the early 1950s, home economics courses were phased out, and female enrollment dropped significantly.
Despite maintaining agricultural offerings, declining student numbers led South Dakota State College to discontinue the high school-level curriculum in 1959. The school was officially closed in June 1960, after the final class graduated. Its closure marked the end of a transitional institution that had long served rural South Dakota youth at a time when access to secondary education was limited.
