The Voices of Youth Count initiative's systematic evidence review is the most comprehensive synthesis of evaluation evidence on programs and practices related to youth homelessness to date. Herein, evaluations of outreach interventions for youth experiencing homelessness are summarized. Outreach is a set of activities in which service providers send staff or volunteers directly into the community--often to the streets--to engage individuals who might not otherwise access supports and services. The evidence here includes only impact evaluations designed to assess measurable changes in outcomes due to specific programs and practices.
