In its resolution 20/15, the Governing Council requested the Executive Director “to undertake an independent strategic evaluation of the performance and impact of the Habitat Programme managers (HPMs) before the end of 2006 and to report thereon to the Governing Council at its twenty-first session”. The terms of reference of this evaluation were finalized by the Secretariat at the end of 2005, in consultation with the Committee of Permanent Representatives (CPR) to UN-HABITAT. The evaluation process started with a self-assessment by the HPMs themselves, followed by an overall assessment by UN-HABITAT headquarters, which was shared with the CPR in May 2006. The external evaluation took place during June-October 2006. It included a desk review of all pertinent documentation, a number of structured interviews with resource persons and evaluation missions to eight developing countries where HPMs have been active for at least two years. This external evaluation was made possible thanks to a financial contribution from the Government of Sweden. The present evaluation report is submitted to the Governing Council as HSP/GC/21/INF/3 while an Executive Summary of the same report is submitted as HSP/GC/21/2/Add.8.
