This booklet is a practical guide for managers of joint evaluations of development assistance programmes. It is a revision and update, in view of new experiences, of the DAC publication Effective Practices  in  Conducting  a  Joint  Multi-Donor  Evaluation  (2000). The omission of the words "Multi-Donor" from the new title reflects the momentum in development cooperation towards broader partnerships and, specifically, joint evaluations undertaken with the participation of non-donor agencies. The update is based on the findings and recommendations in a DAC Evaluation Network Working Paper prepared by consultant Horst Breier in 2005.2 It also draws on the outcomes of a workshop: "Joint Evaluations: Challenging the Conventional Wisdom - the View from Developing Country Partners" (Nairobi, 2005) and on inputs and feedback from members and partners of the Evaluation Network.
