Evidence Tools

Our Evidence Tools support those working in homelessness to have greater impact.

We believe that reliable evidence is critical to helping people make informed, impactful decisions in their work.

Our Evidence Tools for homelessness make the evidence that’s available more useful and more accessible. These tools will show what the evidence tells us about homelessness interventions today and will help you make smarter decisions about how to best serve those experiencing homelessness in the future.

Intervention tool

A single, accessible and trusted entry-point to current body of evidence for homelessness interventions. The tool provides one-page overviews of the available evidence, including simple ratings for strength of evidence, cost-effectiveness and impact, as well as detail on what the studies say about each intervention. Use this tool as a reliable and accessible starting point for making evidence based decisions. >> View tool


Our Evidence and Gap Map for homelessness brings together the highest quality evidence on homelessness from around the world to highlight where evidence does or doesn’t exist for specific interventions and outcomes. This will allow those working in homelessness to be more strategic about how they fill the gaps in knowledge. We envisage a series of maps being created over time and are currently working on a second one on process evaluations. >> View the first Evidence & Gaps Map


Use our evidence finder to see where high-quality studies have been conducted from around the developed world. Future version will include filtering features. Each pin will provide a link to the original study. The studies from this map come from our Evidence and Gap Map of effectiveness studies. We will continue to add new studies as they become available. We are also creating a map of process evaluations which will be available in summer 2018. >> View Evidence Finder

Based on up to date and reliable evidence, it outlines five strategies which offer the best chance of success.. >> View SHARE Framework
