This report was written in an effort to establish a new strategy for reducing the odds of failure for thousands of Arizona's vulnerable children and their families. It echoes the sentiments of a growing number of policymakers, concerned citizens, and parents who hold that the cost of child and family problems is so dramatic, and the amount of preventive investment so inadequate, that substantive and radical changes must occur in the design, delivery, and philosophy of child and family services if children's lives are not to be horribly damaged. The recommended strategy is new in the attention it gives to the interrelated nature of families' problems and the designing of an integrated, comprehensive family support system that is accessible and understandable. Section 1 of this report describes the troubling condition of Arizona's children. Section 2 articulates a prevention strategy that could fundamentally change the approach to the delivery of services to vulnerable children and their families. Section 3 describes an agenda for moving Arizona's policies and priorities toward investment, rather than expenditure, for Arizona's children and families. Attachments include descriptions of innovative programs in several states and source information. (RH)
