The University of California Cooperative Extension’s 4-H Youth Development programs are at the cutting edge of positive youth development knowledge and practice. The 4-H program has a proven record of developing youth. 4-H members make contributions to their communities, are civically active, participate in science programs, make healthy choices, increase their opportunities to attend college, and contribute to improving youth and family quality of life (Lerner, Lerner et al., 2016). In 2015, University of California Agriculture and Natural Resources (UC ANR) understood and accepted the challenge of examining how the 4-H Youth Development Program could better serve diverse audiences by investing $2,000,000 over a period of three years to pilot an intentionally focused effort to develop culturally relevant and responsive programs to welcome Latino youth, families, and volunteers to 4-H. Seven counties (Kern, Merced, Monterey, Orange, Riverside, Santa Barbara, and Sonoma) were selected representing rural, suburban, and urban communities and because they were either a 2013 US Department of Agriculture (USDA) review site or had ongoing successful efforts reaching Latino youth. The UC ANR 4-H Latino Initiative is aligned with the UC ANR Strategic Vision 2025 in providing for healthy families and communities, the Healthy Families & Communities Strategic Plan, the UC ANR 2016-2020 Strategic Plan, particularly with increasing the reach of UC ANR (Goal 2), and the UC ANR public values of ensuring safe and healthy California for all people and communities and contributing to reduced racial and ethnic inequality. This paper reviews the project and its impacts.
