The DAC conducts periodic reviews to improve the individual and collective development co-operation efforts of DAC members. The policies and efforts of individual members are critically examined approximately once every four years. Some five programmes are examined annually.

The Peer Review is prepared by a team, consisting of representatives of the Secretariat working with officials from two DAC members who are designated as examiners. The country under review provides a memorandum setting out the main developments in its policies and programmes.

Then the Secretariat and the examiners visit the capital to interview officials, parliamentarians, as well as civil society and NGO representatives of the donor country to obtain a first-hand insight into current issues surrounding the development co-operation efforts of the member concerned.

Field visits assess how members are implementing the major DAC policies, principles and concerns, and review operations in recipient countries, particularly with regard to poverty reduction, sustainability, gender equality and other aspects of participatory development, and local aid co-ordination.
