UNEG was established in January 1984 as the Inter-Agency Working Group on Evaluation (IAWG). During the 80's and 90's, the IAWG served as an informal group made up of the Heads of evaluation offices who met annually to discuss evaluation issues. In 2000, an evaluation of the IAWG found that whilst it provided a useful platform for UN Agencies to discuss emerging evaluation issues, it needed a more proactive function with specific deliverables that could be used by the UN system in their evaluation work.The recommendations also emphasized the need for structured interaction among members, annual work planning, work groups to move the agenda forward and developing a website to enhance knowledge sharing. Since 2000, IAWG has continued to go from strength to strength in terms of focus, direction and output. In 2003, to mark the rebirth of the group, the IAWG changed its name to the United Nations Evaluation Group (UNEG).
