As part of a series of reports designed to support the implementation of Proposition 10: The California Children and Families Act and to provide comprehensive and authoritative information on critical issues concerning young children and families in California, this report addresses how Proposition 10 Commissions can organize their work and their thinking to develop a strategy to ensure that all children enter school in good health and ready to learn, and how commissions can oversee the implementation of these strategies. The report begins with a discussion of the language of accountability, describing four ideas as the basis for definitions: (1) results or outcomes or goals; (2) indicators to quantify achievement of results; (3) strategies with a reasoned chance of improving results; and (4) performance measures. The report then explores a thinking process underlying results accountability that can help direct the work of creating a strategy to meet the goals; this section then details an eight-step planning approach for Proposition 10 Commissions: (1) get people together; (2) choose indicators of child health and school readiness; (3) develop baselines and the story behind the baselines; (4) consider what works; (5) craft "what works" ideas into a coherent strategy; (6) implement that strategy; (7) use performance accountability to assure quality; and (8) revisit each step to improve the action plan. The report concludes with an imaginary press conference 10 years hence describing the improvements related to investments made by the state. The report's first two appendices delineate relevant organizational and print resources and outline an approach to Proposition 10 planning and language choices. (KB)
