This paper, jointly produced by the Center on Assets, Education, and Inclusion (AEDI) at the University of Kansas and the Federal Reserve Bank of Boston, was informed by a roundtable on CSA delivery systems, held at the Boston Fed in December 2014. It describes the design, key features, and respective challenges of each principal delivery system. Assessed in light of the CSA field’s guiding principles for delivery system design (universal and automatic enrollment, national footprint, cultivation of a saver identity, asset-building, administrative efficiency, and adequate consumer protection), these models have distinct advantages and limitations. This paper attempts to contribute to the critical task of building the knowledge base needed to help children’s savings programs begin to weigh the pros and cons of each of these existing delivery systems.
