The Internal Audit Division has regular contacts with similar services of other International Organisations, in particular OECD, Interpol, CERN, NATO, UNESCO and United Nations' offices in Geneva. These contacts are useful for sharing good practices, tools and methodologies.

The Evaluation function was peer reviewed in 2017 by the Swiss Agency for Development and Cooperation which made a number of recommendations which are currently being implemented. The Evaluation Division co-operates with the evaluation offices of the European Commission and maintains regular contacts with EU delegations and other donor representatives in the countries where evaluations are conducted.

The Evaluation Division is also an institutional member of the European Evaluation Society, which enables it to keep up to date with developments in the evaluation field.
