The Governance and Anti-Corruption Country Diagnostics is a survey tool, which uses information gathered from in-depth, country-specific surveys of households, businesses, and public officials about institutional vulnerabilities. The tool is used by the World Bank and partner governments to measure and evaluate critical governance challenges within the public sector.

The diagnostic tool aims to address two of the fundamental challenges policy makers face when trying to curb corruption and improve governance: (i) to obtain the most relevant type of information to identify priorities for reform; and (ii) to create the conditions for sustaining the reform process over time. The results of the surveys allows countries to unbundle corruption (administrative, state capture, bidding, theft of public resources, purchase of licenses); identify weak and strong institutions; assess the costs of corruption to different stakeholders; and identify concrete and measurable ways to reduce those costs. The ultimate goal is to improve the quality of public services by improving governance in personnel and resource management, access to services and citizen feedback mechanisms by feeding into participatory and targeted reform planning.

As of 2013, 23 countries in Latin America, Eastern Europe, and Africa have implemented the surveys.
