Background: Research suggests that schools' capacity to successfully implement and sustain reform programs may rest, in part, with district-level facilitation. The importance of district leadership has been established for a variety of educational reforms, including school, family, and community partnerships. However, few studies have been conducted to understand how successful district leaders implement and sustain school, family, and community partnerships as an educational reform. Focus of Study: This case study seeks to fill this gap. It describes leadership strategies employed by the office of parent involvement in an urban school district in the United States. More specifically, this article focuses on the collaborative relationship between the office of parent involvement and a community-based parent involvement organization (CPIO). Research Design: The study employed a multiple case study design, which included interviews with district, school, and parent leaders; observations of workshops, meetings, presentations, and other work-related activities of key district-level respondents; document collection and review; and school site visits. Findings: Analyses suggest that the collaboration between the district's office of parent involvement and the CPIO has helped to support and sustain school, family, and community partnerships as a reform initiative for nearly a decade. The relationship has resulted in (1) complementary parent leadership training for school-based partnership teams, (2) joint planning and implementation of districtwide partnership activities, and (3) community advocacy for district partnership personnel and resources.
