It is often assumed that parent participation in schools is primarily based on self-interest and that this is a frequent source of contention between parents and teachers. This article examines the experiences of members of the Jamaica Plain Parent Organizing Project (JP-POP), a community-based organization in Boston, and reveals that some parents have learned to act beyond their individual self-interest and to organize on behalf of the entire community as a result of their participation. The authors present qualitative data from interviews with JP-POP members to ascertain the motivations behind their initial decisions to become involved in education, the benefits they derive from their participation, and the gradual evolution of narrow definitions of self-interest to more communal understandings. Finally, they draw out implications for the potential capacity enhancement of community-based organizations in education at both the institutional and district levels.
