3ie, in partnership with the Uganda Office of the Prime Minister (OPM Uganda), is implementing a multi-year programme to strengthen the production and use of evaluation evidence with selected ministries. The Ugandan government has identified key development issues in which quality evidence about programme effectiveness is lacking. 3ie is supporting a range of evaluations to help fill those evidence gaps. Moreover, 3ie is working with the ministries to strengthen evidence use in their work. OPM Uganda is a member of 3ie, and we have been working with them for many years to build a culture of evidence use and strengthen the national monitoring and evaluation system.
