Full-service community schools do more than educate; they partner with the community to provide the supports and services that students and families need through one comprehensive, coordinated effort. By offering services on-site, full-service schools can help eliminate some barriers that families face such as problems with transportation, lack of health insurance, and inability to take time off from work. Evaluations of community schools have identified a range of positive outcomes associated with the approach such as improved student achievement, increased parental involvement in student learning, decreased student absenteeism, improved student mental and physical health, and greater family knowledge of and access to community agencies and facilities. Since every full-service school looks different depending on the needs, interests, and available resources of the particular community, it is difficult to provide a step-by-step guide for implementing one. Perhaps some of the best advice offered in the literature is to start small and build gradually. This article discusses how to "build" a full-service community school, the barriers to full-service schools that partners should address during the planning phase, and lessons learned that can be helpful to schools considering the concept.
