TDLC TDD is a first-hand knowledge exchange program including workshops, site visits, peer-peer knowledge sharing and action planning, which aims to foster operational development of World Bank funded projects in specific topics in close collaboration with the World Bank's Communities of Practice. The group aims to guide the new TDD participants who will be participating in the TDD programs as well as to serve as a community platform for the alumni of TDD participants. TDDs are organized by the Tokyo Development Learning Center (TDLC), a partnership project of Japan and the World Bank launched in June 2004. view less
