The Independent Evaluation Group's (IEG) Results and Performance of the World Bank Group (RAP) is a comprehensive assessment of World Bank Group performance, drawing on recent IEG evaluations. The report also examines how effectively the World Bank Group addressed current and emerging development challenges. This year's RAP focuses on gender integration in World Bank Group operations, building on previous examinations of World Bank Group approaches to risk management (RAP 2013) and the Millennium Development Goals (RAP 2014). 'No country, community, or economy can achieve its potential or meet the challenges of the 21st century without the full and equal participation of women and men, girls and boys.' This statement from the World Bank Group website's topic page on gender states the essential importance of gender for development. In line with that view, the World Bank Group made considerable progress in addressing gender issues during the past 15 years. Gender has been a prominent corporate objective since the first World Bank Group strategy, introduced in 2001. This year, a new World Bank Group gender strategy has been launched - the first joint World Bank - International Finance Corporation (IFC) strategy to focus on gender. It is an important step toward sharpening the corporate focus on gender and improving the approach to gender mainstreaming. This report describes how mechanisms for integrating gender in projects and country strategies are working, and to what extent they provide meaningful information about progress and results on gender. The analysis aims to inform World Bank Group efforts to strengthen the approach to documenting, assessing, and evaluating results as part of the new strategy rollout. The report also reviews how effectively the World Bank Group's portfolio and country programs deliver results, and its system for monitoring the implementation of IEG's recommendations.
