All universities engage in research and teaching, but the nation’s 111 Land-grant Universities and Colleges, including Historically Black Land-grant Universities and Tribal Colleges, have a third critical mission—Extension. “Extension” means reaching out and extending university research and resources to meet public needs through non-formal educational programs at the community level. The Cooperative Extension System (CES) engages people in these educational opportunities to help them solve problems, develop skills, and build a better future where they live and work. With thousands of Land-grant University and county-based Extension employees and over 2 million volunteers, CES crosses every state and U.S. territory. Working with a network of public and private organizations, CES brings science-based resources to the people and communities who need them most.
