UN-Habitat evaluates its work to assess how well its interventions are achieving the intended results and how effectively they are contributing to broad development goals. This is done by assessing what is achieved and by making recommendations that feed into policy, programme/ project development and implementation. Evaluation plays an integral role in helping UN-Habitat become more effective and improve accountability and transparency. UN-Habitat commissions and conducts two types of evaluations: Centralized evaluations managed by the UN-Habitat Evaluation Unit and decentralized evaluations managed by programme and project managers with technical support from the Evaluation Unit. In addition, other entities such as donors may commission evaluations of UN-Habitat programmes and projects.
