Based on observations of hundreds of school-age child care programs across the nation and conversations with parents, children, and professionals in school-age care, this training guide is intended to help parents, caregivers, and interested citizens to develop quality school-age programs in their communities. The guide begins by summarizing an instructional video which features a step-by-step approach to using the four keys to a quality program: (1) planning with school-age children in mind; (2) organizing for diversity and choice; (3) viewing parents as partners with programs; and (4) collaborating with others who can help. Uses of this video are also outlined. The guide then discusses common challenges for school-age programs. The next two sections of the guide contain trainer notes on workshops for parent and community groups, including a checklist for determining how well a program meets the four keys, and on workshops for school age professionals. Four training modules for these workshops, with exercises, are then presented, based on the four keys to success. The remainder of the document contains supplementary readings and worksheets of relevance to school-age programs on such topics as programming for older children, problem solving, and keeping parents informed.
