To understand the US Interagency Council on Homelessness’s (USICH’s) role in the nation’s efforts to end homelessness and potential effects of the agency’s planned termination in 2017, we interviewed more than 40 federal and local stakeholders across the public, private, and nonprofit sectors. Tasked with coordinating the federal response to homelessness, USICH is perceived as uniquely positioned to help federal, state, and local actors achieve the nation’s ambitious goals. Overwhelmingly, stakeholders considered USICH an important part of a highly effective performance-driven partnership and argued that terminating USICH could slow down efforts to end homelessness.
