As part of a subcontract to Campaign Consultation’s work for the Corporation for National & Community Service, Community Science reviewed mentoring and non-mentoring programs available to youth aging out of foster care to determine what worked and didn’t work and why. This review consisted of 1) an examination of both peer-reviewed literature and non-peer reviewed literature (e.g., reports published by professional organizations) relating to youth aging out of foster care programs, and 2) telephone interviews with key informants in four states (California, Florida, Massachusetts, Michigan) who work with volunteers, mentors, and service providers to provide services for youth aging out of foster care.
