Our mission is to help Cooperative Extension generate a more visible, measurable, local act. We achieve this through our nationally funded programs made possible by member dollars and cooperative agreements with federal agencies, and through partnering on state, regional, and national initiatives with Cooperative Extension and the Extension Committee on Organization and Policy (ECOP). We serve all Land Grant Universities, regardless of membership status.
