The Tool provides one-page overviews for each of the main interventions in homelessness. At a glance, the overviews give ratings for how reliable the body of evidence is, how cost effective the intervention is and what kind of impact it has for people experiencing homelessness. These measures represent an aggregate of the available studies.

Each overview will also provide a breakdown of the findings from the body of evidence, including detail on what the body of evidence says about how the intervention works, which population groups and outcomes it affects and where in the world the evidence comes from. As the evidence base grows, particularly with the inclusion of process evaluations (which will tell us about how interventions have been implemented), we will also be including a section that covers considerations for implementation.
