Throughout the United States, approximately 2.7 million grandparents are the primary caregivers of their grandchildren. The National Association of Social Workers (NASW) created a standard of practice and established policies to equip social workers to support grandparent caregivers. However, grandparents caring for children with autism spectrum disorders (ASD) may have unique challenges and needs, requiring social workers to have a more nuanced understanding of the impact of ASD on these families. A literature review shows a small but growing body of research that outlines the challenges grandparents experience when raising their grandchildren with ASD. To contribute to the scholarly literature and generate timely educational information for social workers, this action case study research examined grandparent caregivers' experiences to shed light on the implications of and challenges faced when raising grandchildren with ASD. The overarching question that directed this research was: what can be done to address the challenges experienced by grandparents raising grandchildren with ASD? A qualitative case study approach was used, and data were collected via individual interviews, focus groups, and field notes. The unique challenges faced by grandparent caregivers are presented in the findings to help social workers, and other stakeholders develop a better understanding of their experiences and needs. Themes indicated that grandparent caregivers experienced a new purpose, as well as financial, educational, and community resource challenges. A visual media report was generated using PowerPoint to present findings to stakeholders. Recommendations are provided to stakeholders to support caregivers of children with ASD.
