 Who We Are

    4-H is the nation’s largest youth development organization, empowering six million young people throughout the United States!

4‑H programs are grounded in the belief that kids learn best by doing. Kids complete hands-on projects in areas like science, health, agriculture and citizenship, in a positive environment where they receive guidance from adult mentors and are encouraged to take on proactive leadership roles. Kids can concentrate on one focus area or they can try a variety of programs throughout their 4‑H experience.
