This report examines private sector engagement in youth mentoring across the United States, starting with an overview of the youth mentoring movement, then offering perspectives on trends and best practices in corporate engagement and snapshots of a range of initiatives. The information provided in this report is based on a series of structured interviews MENTOR conducted with 18 of the nation's leading mentoring efforts in the private sector. These interviews explored: (1) Companies' motivations for getting involved in mentoring; (2) The ways mentoring benefits companies and their employees; (3) The myriad approaches companies take to support programs and meet youth needs; (4) How companies leverage their strengths to maximize impact; and (5) The biggest challenges and successes to date. Representatives from leading youth-serving organizations and MENTOR's network of affiliate Mentoring Partnerships were consulted to get their perspectives on corporate engagement and support in the mentoring field. This report offers a fascinating look at the many ways that corporate America is engaging, supporting and participating in the youth mentoring movement. The hope is that these case studies, program profiles and insights from the field will inspire others--from Fortune 500 companies to local and regional business--to get involved in mentoring in a variety of ways. The stories of these 18 corporate youth mentoring leaders paint a clear picture of a growing movement. They also provide valuable examples, information and advice for those who are thinking about getting off the sidelines and making a profound difference in the lives of youth.
