Features contributing to the success of six city-wide, comprehensive school-age program models are highlighted. Models are Seattle, Washington's Community Partnerships for School-Age Child Care; Madison, Wisconsin's School-Age Child Care Project; Irvine, California's Irvine Child Care Project; Houston, Texas' After-School Partnership; Los Angeles, California's LA's BEST: Better Educated Students for Tomorrow; and Baltimore, Maryland's School-Age Child Care in the City of Baltimore. Section I presents reasons for city-level involvement in school-age child care. Replicable features of the models are discussed in Section II, including: (1) adoption of a "broker" management and coordination model; (2) hiring of at least one individual to match expertise and resources with needs; (3) government funding matched with private sector donations; (4) multiple agency involvement; (5) public shool involvement; (6) quality enhancement; and (7) funding for low-income families. Section III presents detailed descriptions of each model by describing its goals, administrative structure, program design, and financing. (RH)
