In 2003, the South Korean national government implemented a systematic school social work program known as the Education Welfare Priority Zone Plan (EWPZP). The EWPZP was designed to enable all related educational and social agencies in a zone to serve students in need by situating schools within the communities’ welfare networks. This research project aims to examine the characteristics of educational welfare networks in a target area in Seoul, South Korea, and assess levels of inter-agency collaboration. The authors also suggest that the EWPZP project needs to institutionalize greater collaboration between schools and welfare organizations and to make networks tighter.
