This is the third of a 3-part series on how to locate, obtain, and manage Federal money for children's services. This manual concentrates on the contracting of money for specific programs. Emphasis is on Title XX of the Social Security Act, but attention is given also to alternative sources where Title XX funds are not sufficient. Although useful for public agencies, the series is aimed primarily at voluntary child welfare agencies and other nongovernmental child advocacy groups. Sections include (1) Program Description: basic requirements and program description checklist; (2) Contract Requirements; (3) Additional Regulatory Constraints; and (4) Pricing the Service: federal requirements, a full-cost expenditure base, optimal allocation of costs and revenues, reimbursement for all entitled children, calculating the rate, and payment intervals. A glossary of technical terms and acronyms, Federal guidelines on cost principles, and sample contracts are provided. (Author/SB)
