Organizational Context and Scope

The International Organization for Migration (IOM) is the leading intergovernmental organization in the field of migration, working to promote humane and orderly migration for the benefit of all. With over 175 member states and more than 600 field locations worldwide, IOM provides services and advice to governments and migrants on a broad range of migration issues. Evaluation at IOM serves three main purposes: (a) it demonstrates accountability to stakeholders on the Organization’s work; (b) supports evidence-based decision-making; and (c) contributes to organizational learning through lessons learned. As per the IOM Evaluation Policy (IN/266), evaluation is an integral part of the Organization’s core and managerial functions.

IOM conducts evaluations at two levels: centralized evaluations, managed by the Central Evaluation Division (CED) within the Office of Internal Oversight (OIO), focus on corporate, strategic, and thematic issues of organization-wide significance; decentralized evaluations generally focus on specific programmes and interventions, and are commissioned and managed outside of the CED. A network of Regional Planning, Monitoring and Evaluation Officers (RPMEOs) is currently in place in IOM Regional Office to oversee and support the production of decentralized evaluations, with the CED providing overall guidance. Both evaluation levels adhere to the United Nations Evaluation Group (UNEG) Norms and Standards and contribute to organizational accountability, learning, and performance improvement.

The IOM Deployment Roster for Evaluators serves to establish a vetted pool of qualified evaluation consultants with both demonstrated expertise in conducting impartial and credible evaluations and a proven track record of delivering high-quality evaluation reports. Roster members will be engaged for decentralized evaluations primarily. This roster mechanism reflects standard practice across the UN system and aims at ensuring timely access to qualified evaluators through streamlined selection processes, while also enhancing performance tracking and management.
