The current wave of educational reform includes an emphasis on family and community involvement as a strategy for school improvement. Yet, to effectively engage families and communities in the educational process, educators need assistance and support. In 1996, the National Network of Partnership Schools (NNPS) was established to build the capacity of educators to work collaboratively with families and community members to develop comprehensive programs of school, family, and community partnerships that focus on students' success. Using survey data collected from 603 schools that are members of NNPS, this paper examines whether particular structures, processes, and services positively influence schools' capacity to implement and maintain high quality partnership programs over time.
