Latino, Spanish-speaking families of children with autism spectrum disorder (ASD) face unique barriers in special education advocacy. Although advocacy programs are becoming more common in the United States, none of these programs target Latino families. This is a pilot study to examine the feasibility and effectiveness of an advocacy program for Latino families of children with ASD. Using a quasi-experimental design, 40 Latino family members of children with ASD participated in this study. Results demonstrated consistent attendance, low attrition, and high participant satisfaction. Intervention (versus control) group participants demonstrated significantly increased empowerment and special education knowledge, and stronger family–school partnerships. Findings provide preliminary support for advocacy programs for Latino families of children with ASD.
