This report describes the importance, collaboration procedure, and principles of linking integrated service systems that are community-based and school-linked, established by the National Consensus Building Conference on School Linked Integrated Service Systems. The consensus principles aim to create comprehensive, effective, community-based service systems; make support available to children, youth, and families; and focus on prevention. The report consists of two parts. The first part explains how the consensus was developed and what action will be taken next. The second part describes consensus principles relating to: (1) the basic elements of preventive strategies and effective services; (2) the role of financing; (3) the role of needs assessment and program evaluation; and (4) the importance of stronger structures for coordination.
