The document summarizes the EvalPartners Initiative, an international collaboration of 34 organizations working to strengthen evaluation capacity development globally. It describes Voluntary Organizations for Professional Evaluation (VOPEs) and outlines EvalPartners' efforts to map existing VOPEs, support partnerships between VOPEs through a peer-to-peer program, develop evaluation advocacy and capacity building tools, and declare 2015 as the International Year of Evaluation. The overall goal is to promote collaboration and evidence-based policymaking through evaluation.
