To function well, every system has to fully understand and manage its resources. Mapping is a first step toward enhancing essential understanding, and done properly, it is a major intervention in the process of moving forward with enhancing systemic effectiveness. In schools and community agencies, there is redundancy stemming from ill-conceived policies and lack of coordination. A primary and essential task in improving the current state of affairs is that of enumerating school and community programs and services that are in place to support students, families, and staff. Analyses of what is available, effective, and needed provide a sound basis for formulating strategies to link with additional resources at other schools, district sites, and in the community and to enhance use of existing resources. Such analyses can also guide efforts to improve cost-effectiveness. This technical aid packet focuses on the purpose of mapping resources, processes for mapping resources, and products of mapping. A directory of additional resources is provided and an appendix presents examples of surveys that aid in mapping. (GCP)
