Twenty years have passed since conditional cash transfer programs were first implemented in Latin America and the Caribbean. This book takes the opportunity to critically review the design options and operational solutions employed by the countries in the region, with the goal of systematizing this accumulated operational knowledge and identifying both good practices and remaining challenges. It addresses the major processes of the operational cycle: beneficiary identification and management of the rosters of beneficiaries, verification of conditionalities, and payment of transfers. In addition, it discusses cross-cutting issues, such as territorial organization, management information systems, and the linkage of beneficiaries to other social programs. This book is a useful and practical tool for those seeking to understand how transfer programs work and how they can be improved by building on the experiences of other countries.
