International donor agencies are the principal actors responsible for delivering aid and executing development projects in aid-recipient countries. Their presence in corruption-prone environments, frequent interaction with local partners and contractors, as well as the overlapping oversight and regulatory jurisdictions are all factors that increase donor agencies’ vulnerability to corruption. Many donor agencies have implemented anti-corruption training programmes centred on anti-fraud, as well as the identification of corruption risks and potential conflicts of interest. However, there is scant information in the public domain about aid agencies’ specific anti-corruption training curricula. After surveying topics typically covered in donor agencies’ anti-corruption training programmes, this Helpdesk answer looks at training provided by the World Bank, AusAid, the Asian Development Bank and UN agencies, all of which stand out because of their comprehensive application of anti-corruption training in their operations.
