Opportunities existed to improve how the Department of Housing and Urban Development (HUD) evaluated the Moving to Work (MTW) program, which is intended to give participating public housing agencies (PHA) flexibility to design and test innovative strategies for providing housing assistance. GAO reported in April 2012 that HUD had not (1) developed guidance specifying that performance information collected from MTW agencies be outcome-oriented, (2) identified the performance data needed to assess results, or (3) established performance indicators for the program. The shortage of such standard performance data and indicators had hindered comprehensive evaluation efforts; such evaluations are key to determining the success of any demonstration program. In addition, HUD had not developed a systematic process for identifying lessons learned from the program, which limited HUD’s ability to promote useful practices for broader implementation. Since the GAO report, HUD has revised reporting requirements for MTW agencies. These requirements were approved by the Office of Management and Budget in May 2013. GAO is reviewing this new guidance.
