Evaluation Studies represent evaluation of the quality, effectiveness and efficiency of implementing various Bank programmes, strategies and policies, including regular overall institutional performance reviews. They provide independent in-depth analysis and suggest amendments and measures to improve the overall Bank performance and achievement of its mandate. Some studies analyse and compare the findings of evaluations of individual operations in order to reveal trends as well as to distil lessons that have implications beyond the particular operation or sector. Other studies look at key issues of interest for the Bank and may focus on international/IFI best practice, experience or lessons learned. Evaluation Studies often analyse specific sector/country related issues.
