This report presents findings of an evaluation of the International Organization for Migration (IOM) and its efforts to combat human trafficking. It documents and assesses how projects funded by the Norwegian government and implemented in partnership with IOM have sought to counter human trafficking between 2000 and 2010, documents key findings related to these efforts, and provides recommendations. IOM’s major strengths include network-building and victim support, but it faces challenges when ensuring human rights protections and understanding program outcomes.
