This three-part sourcebook identifies school restructuring initiatives with a national scope and presents comprehensive information about them. Part 1 identifies and describes national restructuring programs (e.g., Coalition of Essential Schools, Learning Tomorrow, Success for All). Each program description provides an overview of the program as well as information on its purpose and goals, key features, intended audience or participants, available resources, funding sources and/or costs, and a contact person. The second part is devoted to national restructuring centers (e.g., Center for Leadership Reform, Center on Organization and Restructuring of Schools). Each of the descriptions contains an overview of the center, including its definition of restructuring, a statement of its mission and goals, and information on available resources and funding sources. In each case, a contact address and list of selected readings are also provided. Part 3 focuses on national restructuring agencies (e.g., Business Roundtable, Holmes Group, National Governors' Association) that have either sponsored projects and/or developed materials relevant to school restructuring efforts. Each entry contains an overview of the agency's restructuring effort and information on available materials, a contact source, and a list of selected readings. The appendix includes a list of regional educational laboratories. (LMI)
