This issue of New Directions for Evaluation focuses on evaluation in complex organizations. The themes that are examined the mainstreaming of evaluation within organizations, the growth of evaluation capacity, and the use of evaluation to promote organizational learning are relevant for evaluators who operate in environments marked by multiple organizational levels, varied funding streams, divergent purposes for evaluative information, and numerous stakeholders and organizational partners. The national Cooperative Extension System serves as a recurring case study that links the topics together. Cooperative Extension is a system of institutions that includes every state's land-grant universities, the U.S. Department of Agriculture, and local country governments. The linkages across professional communities and distinct institutions create a highly complex environment, presenting numerous challenges for evaluators working with community-based programs. Extension's experiences contribute to a rapidly evolving knowledge base about effective evaluation practice across a variety of organizational settings.
