This paper describes a reentry housing demonstration design process that will fill the gaps in the literature and strengthen policy and practice. The demonstration would include a range of housing and supportive services for formerly incarcerated persons, primarily focused on making meaningful reductions in returns to incarceration. The associated study would explore whether housing leads to reductions in recidivism and increases in the reintegration of those released from incarceration. Examples of potential partnerships and opportunities for reentry housing programming and funding are discussed. The paper concludes with several key hallmarks for the proposed demonstration to achieve its intended goals.
