In the first part of this report, we describe the types of early childhood education (ECE) outcomes that might be used to establish success payments. In the second and third parts, we describe the steps and key questions that stakeholders might ask when selecting and pricing outcomes. Specifically, we provide guidance on how the partners in a PFS project might select an outcome, a measure, and a definition of success that is appropriate for the project. After that, we outline approaches to assigning dollar values to selected outcome measures. Examples are provided throughout, drawing primarily from the first two ECE PFS projects in the United States. (author abstract)
