Grandparents who take on primary responsibility for raising grandchildren face unique family challenges while helping reduce the burden on the foster care system. The GRandS (Grandfamily Resilience and Sustainability) Program was a family life education program designed with three fundamental goals: (a) increase grandparent caregivers' knowledge and skills in parenting and child development, (b) fortify their relationships with spouses and grandchildren, and (c) inform them about, and connect them to, available community resources. In this article, we describe the program implementation and evaluation, including the use of quantitative analysis and anecdotal accounts. Additionally, on the basis of our findings and experience with the program, we identify factors important to Extension's successfully serving grandfamilies.
