Here, UNDEF publishes all post-project evaluations on-line. The decision to make these public was taken at the November 2011 meeting of the UNDEF Advisory Board, which is committed to evaluations of UNDEF projects as a basis for knowledge-sharing, lessons learned, improved project selection and management, and transparency. In this way, UNDEF consolidates its position as one of the most transparent entities in the UN family.

From 2010 to 2016, most UNDEF post-project evaluations were conducted by a contracted commercial evaluator firm, Transtec. Based in Brussels with a regional office in Beirut, Transtec has broad experience in evaluations, audits and studies in institution-building, democracy, governance, community development and post-conflict rehabilitation. 

Since 2017, as agreed at the UNDEF Advisory Board meeting of November 2016, UNDEF has adopted a new post-project evaluation system managed by UNDEF itself, using a roster of independent evaluators.
