The Handbook on Planning, Monitoring and Evaluating for Development Results (the Handbook) was launched by the UNDP Administrator in September 2009. UNDP commissioned an independent review of the evaluation policy in 2010, as per the provision made in the organization’s first evaluation policy, approved by the Executive Board in 2006. While acknowledging progress made in the implementation of the evaluation policy, the review highlighted a need to revise the evaluation policy to further clarify roles and responsibilities of the key constituents of the organization, emphasize key principles such as national ownership and codify current practice in the policy. In approving the review and UNDP’s management response, the UNDP Executive Board requested the organization to revise the policy, as well as relevant guidance and operational directives such as the Programme and Operations Policies and Procedures (POPP) and the Handbook. The revised evaluation policy of UNDP was approved by the Executive Board in January 2011. This addendum is intended to present changes in the recently approved evaluation policy and how these changes affect guidance provided in the Handbook. The overall principles and guidance on what constitutes good planning, monitoring and evaluations continue to be relevant and important to the UNDP efforts as it strives to be a more results-oriented organization.
