A federal-state-local cooperative education system that provides continuing adult education based on the academic programs of the land grant colleges of agriculture and their affiliated state agricultural experiment stations. The system employs approximately 32,000 people located on land grant campuses and offices in virtually every county in the nation. About half of Extension’s education programs focus on agriculture and natural resources, one-quarter on youth development (including the vocational 4-H program), and the balance on home economics and community resource development work.
