The Independent Evaluation Group (IEG) is an independent unit within the World Bank Group (WBG) charged with objectively evaluating the activities of the International Bank for Reconstruction and Development (IBRD) and International Development Association (IDA; collectively, the World Bank), the work of International Finance Corporation (IFC) in private sector development, and the Multilateral Investment Guarantee Agency's (MIGA) guarantee projects and services to provide accountability, help the WGB avoid unnecessary mistakes and successfully reach their goals.

In 2019, Alison Evans, a United Kingdom national, assumed the position of Director-General, Evaluation at the World Bank Group.

Before this role, Dr. Evans was the Chief Commissioner of the UK’s Independent Commission for Aid Impact (ICAI) based in London, England.

To achieve these goals, the World Bank Group needs to better understand what works and why, to draw lessons and good practices from experience, deepening the evidence base to inform decision making and future action.
