Setting and pricing outcomes are important steps of every pay for success (PFS) project because they allow partners to quantify the benefits of successful programs. This report describe the types of early childhood education (ECE) outcomes that might be used to establish repayments and offers 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. We also outline approaches to assigning dollar values to selected outcome measures.
