SDSU Extension is the indispensable outreach link to people growing South Dakota’s, and the nation’s, future by providing solutions and creating opportunities. We foster learning communities that e​​​​mpower citizens to advocate for sustainable change and strengthen agriculture, natural resources, youth, families and communities.

Youth experience 4-H through in-school and after-school programs, school and community clubs and 4-H camps and educational programs. Members complete hands-on projects in a positive environment where they receive guidance from adult mentors and are encouraged to take on proactive leadership roles.
