The Independent Evaluation Group (IEG) assessed the effectiveness of Bank support for decentralization between fiscal 1990 and 2007 in 20 countries, seeking to inform the design and implementation of future support. Given the difficulties of measuring the results of decentralization, the
evaluation used intermediate outcome indicators-such as strengthened legal and regulatory frameworks for intergovernmental relations, improved administrative capacity, and increased accountability of sub national governments and functionaries to higher levels of government and to citizens-to
assess the results of Bank support in these 20 countries. To examine potential lessons at a sectoral level, the evaluation also assessed whether Bank support for decentralization improved intermediate outcomes for service delivery in the education sector in 6 of the 20 countries.
