Independent Evaluation Group (IEG), World Bank Group

Independent Evaluation Group (IEG), World Bank Group

IEG is charged with evaluating the activities of the International Bank for Reconstruction and Development (IBRD) and International Development Association (the World Bank), the work of International Finance Corporation (IFC) in private sector development, and Multilateral Investment Guarantee Agency's (MIGA) guarantee projects and services.

Evaluation in the World Bank provides an objective assessment of the results of the Bank Group's work and to identify and disseminate lessons learned from experience.

The diversity of projects and programs the Bank Group employs to support public and private sector development requires IEG to use a variety of evaluation approaches. These approaches include assessing outcomes against stated objectives, benchmarks, standards, and expectations, or assessing what might have happened in the absence of the project, program, or policy (counterfactual analysis). For example, private sector investment projects and advisory services are mainly assessed against absolute economic and financial performance criteria and the extent to which they contribute to private sector development. Public sector projects are assessed in relation to their relevance and the efficacy and efficiency with which they achieve their development objectives.

To assess the Bank Group's performance and identify lessons for improving Bank Group operations, IEG conducts not only project-level evaluations, based on the review of self-evaluation reports prepared by Bank Group staff and supplemented by independent assessments, but also reviews of literature, analytical work, and project documentation; portfolio reviews; country case studies; structured interviews and surveys of staff and stakeholders; and impact evaluations.

Resource: To enhance the quality and impact of IEG evaluations, as well as strengthen accountability related to implementation of evaluation recommendations, IEG created the Management Action Record (MAR) database.  This database is an online central repository of IEG findings, recommendations, management responses and progress of implementation
