The World Bank's work in education is anchored in a Bankwide Education Sector Strategy and regional education strategies, revised periodically to ensure that assistance is well aligned with evolving country needs and global circumstances. An Education Sector Strategy was last prepared in 1999 and the vision set out therein remains fully relevant. At the same time, our work in education has continued to be informed by papers prepared for the Bank's Development Committee -- our governing organization -- beginning fall 2001 and other strategic and analytical work in the areas of HIV/AIDS and education, tertiary education, science and technology, and lifelong learning. The Education Sector Strategy Update was finalized in 2006 to reflect new analysis and lessons learned as well as changes in the Bank’s internal and external environment.
