This brief spotlights several Youth Homelessness Demonstration Program (YHDP) communities for how they have fostered youth leadership, as well as for lessons learned that may provide guidance for other communities seeking to establish effective youth collaboration in their local communities. The Youth Homelessness Demonstration Program (YHDP) is a national initiative designed to reduce the number of youth experiencing homelessness. Twenty-three communities were selected in Round 3 of YHDP. As a part of this initiative, these communities committed to authentic collaboration with youth and young adults who have lived experience of homelessness. (author abstract modified)
