The demographic shift resulting from the rapid growth of the Latino population has posed challenges to systems and services necessitating a closer look at families receiving services. One specific Latino subgroup that has had little study is the Mexican immigrant family with a child with a disability who receives early intervention services. Early Intervention services advocate a family centered approach focused on the needs and priorities of the family in order to prevent long-term disability. The purpose of this study was to explore and describe how mothers of Mexican origin who are undocumented residents in the United States participate in their childs early intervention program. Qualitative research allows close analysis of experiences that define a phenomenon. This qualitative study will promote understanding and inform ways to provide efficient and effective service through practical information that serves to increase the cultural competence of service providers.
