Designed for school business officials, this handbook provides research information and guidelines on school district banking and cash management systems. Section 1 gives an overview of district financial management operations, discussing the administrative framework, cash budgeting, information and control systems, collection and disbursement methods, borrowing, investing, investment securities and strategies, and banking. Section 2 summarizes responses to a national questionnaire survey of all chief state school officers on school district cash management practices, laws and regulations governing financial management, district investing and borrowing practices and results, and school-bank relationships. The following section presents state-by-state profiles of cash management operations for all 50 states. Included are data on numbers of districts and students, total K-12 expenditures, and districts' investment earnings and yields, as well as brief summaries of state laws and regulations and district investment practices. The final section consists of a bibliography of 33 documents, 20 of which are annotated, on school district financial management. A copy of the survey questionnaire is appended. (RW)
