With recent developments in the evaluation field such as privatization and mandated outcome-focused evaluation, evaluators today face new and complex ethical challenges regarding stakeholders, the public good, and utility. This volume of New Directions for Evaluation explores how evaluators can avoid, reduce, or resolve the ethical conflicts that arise. The authors offer a cost-benefit approach to exploring the ethics of various research designs and make recommendations for achieving a balance between neutrality and advocacy. They shed light on the ethical challenges evaluators face when collaborating with foundations and communities; working in a culture different from their own; and determining the nature of stakeholder involvement. This is the 82nd issue of the quarterly journal New Directions for Evaluation.
