This report is a self-evaluation of the Operations Evaluation Department's (OED) Country Assistance Evaluations (CAEs). CAEs examine World Bank performance in a particular country, usually over the past four to five years, and report on its conformity with the relevant Bank Country Assistance Strategy (CAS) and on the overall effectiveness of the specific CAS. This Retrospective addresses the question "What Have We Learned?" by compiling lessons relevant for developing country assistance strategies from the most recent batch of CAEs. Second, it assesses revisions to the CAE process.

'The Annual Review of Development Effectiveness 2009' presents evidence on the World Bank s efforts in two areas. Part I tracks the outcomes of Bank projects and country programs and the evolution of monitoring and evaluation (M and E). Part II examines the Bank s support for environmentally sustainable development compatible with economic growth and poverty reduction. The Bank s project performance rebounded in 2008, allaying concerns about the weakened performance in 2007. As previous ARDEs have shown, project performance has been improving gradually for 15 years according to the traditional measure percent of projects with satisfactory (versus unsatisfactory) outcomes. But IEG ratings of M and E quality for completed projects indicate considerable room for progress. Information to assess impacts continues to be lacking although preliminary data suggests improvements in baseline data collection. Bank support for the environment has recovered since 2002 due to new sources of concessional finance. The outcomes of environment projects have improved in recent years. A growing number of regional projects are addressing the shared use of water resources. New global partnerships are deepening the Bank s involvement in climate change issues. But M and E remains weak: three-quarters of environment-related projects those managed by sectors other than environment lack reporting of environmental outcomes.

The '2005 Annual Report on Operation Evaluation' examines the use of information by World Bank managers to improve development results and enhance the effectiveness of the Bank at the country level. It suggests that greater attention is needed to measure and manage development results at the country level. This will require strengthening countries' performance measurement capacity. The Bank is making progress in strengthening the results focus of its monitoring and evaluation, but more attention is needed to improve performance measurement and tracking progress.

This series continues to strengthen its focus on results, monitoring, and evaluation. The latest 2006 edition updates the implications of managing for results in World Bank operations, assesses if monitoring and evaluation practices provide staff with information that helps them manage for results, and looks at IEG's own effectiveness. Its recommendations address ways to make monitoring and evaluation more effective and influential tools.

An independent evaluation of the World Bank's extensive support to developing countries on trade issues between 1987 and 2004. The study assesses the development effectiveness of World Bank trade-related advocacy, capacity-building, lending and research. It examines the extent to which the Bank's policies and assistance have met its stated objectives in the area of trade and makes recommendations to strengthen the effectiveness of future Bank trade assistance.

"The World Bank has committed itself to becoming a ""global knowledge bank,"" using knowledge to improve the development effectiveness of its work. Two of the analytical and advisory ways the Bank provides knowledge to its client countries are economic and sector work (ESW) and nonlending technical assistance (TA). ESW and TA are an essential part of the Bank's engagement with its clients-it spent $910 million (26% of its spending on country services) on these products during fiscal 2000-06. This evaluation assesses the extent to which the stated objectives of ESW and TA have been met. It also assesses whether the way ESW and TA are originated, partnership with clients in production, technical quality, and dissemination of these products influence the extent to which the stated objectives are met."

The effectiveness and efficiency of a country's public sector is vital to the success of development activities, including those the World Bank supports. Sound financial management, an efficient civil service and administrative policy, efficient and fair collection of taxes, and transparent operations that are relatively free of corruption all contribute to good delivery of public services. The Bank has devoted an increasing share of its lending and advisory support to the reform of central governments, so it is important to understand what is working, what needs improvement, and what is missing. IEG has examined lending and other kinds of Bank support in 1999-2006 for public sector reform in four areas: public financial management, administrative and civil service, revenue administration, and anticorruption and transparency. Although a majority of countries that borrowed to support public sector reform experienced improved performance in some dimensions, there were shortcomings in important areas and in overall coordination. . The frequency of improvement was higher among IBRD borrowers than among IDA borrowers. . Performance usually improved for public financial management, tax administration, and transparency, but did not usually with respect to civil service.
