Like policy evaluations, sector and thematic evaluations are conducted on a sample of projects in a particular sector or relating to a specific theme of Bank lending where there is a high probability of learning lessons relevant for the design of future operations. The sample may include on-going as well as completed projects and the sector or thematic area may be covered by a formal Bank strategy. Ten sector and thematic evaluations conducted in 2002 and 2003 assessed Bank strategies, but concluded that formal strategies provided relatively weak guidance in Bank operations design. As a result, future work will focus on evaluation of the projects themselves rather than sector and thematic strategies.
