This article reviews the primary concepts underlying the current movement toward the provision of comprehensive school-linked services for children and families in low-income communities and the implications of this movement for school psychologists. The development of collaborative partnerships involving schools, public, and community-based agencies is an attempt to increase the availability and accessibility of needed services to children and families. The adoption of collaborative governance and a case management system is intended to offer an alternative to the proliferation of separate categorical programs and the associated lack of coordination among programs. The hope is to emphasize prevention and efficient early intervention. Collaborative efforts can provide an opportunity for role expansion among school psychologists. This possibility is discussed within a consultation model of service delivery that is consistent with the collaborative nature of school-linked services and with the preventive stance that orginated them. School psychologists are in a position to contribute to team consultation, case management, and needs assessment. Implications for training are drawn.
