Who We Are

Cooperative Extension is a statewide non-formal education network bringing research-based information into communities to help people improve their lives. Established by Congress in 1914, today's Cooperative Extension is many things to many people throughout Arizona.

Our mission is to engage with people through applied research and education to improve lives, families, communities, environment, and economies in Arizona and beyond.
