This toolkit was developed specifically for provider organizations that employ or want to employ young adult peer providers, who we call "YA peers" in this toolkit. Provider and program leadership must support peers, co-workers and supervisors to work collaboratively through enhanced trainings, team building strategies, personnel policies, and sharing their enthusiasm for the potential of the YA peer role. This toolkit provides employers with direct guidance on how to enhance their capacity to sustain and grow a young adult peer workforce.
