Volunteers are the HEART of the 4-H program. 4-H Youth Development volunteers and Cooperative Extension staff are partners, working with youth to create safe spaces and caring relationships. To ensure these positive environments and relationships, Arizona 4-H requires a fingerprint-based background check and a minimum level of training before certifying that volunteers are ready to work with youth from other families.
