Fostering Healthy Futures (FHF) is a randomized controlled trial of an intervention for preadolescent youth placed in foster care because of maltreatment. As part of the FHF program, graduate students spend sixteen to twenty hours per week mentoring two youths in foster care and receiving intensive training and supervision. During summer and fall 2009, fifty of the fifty-two mentors who participated in the FHF program between summers 2002 and 2008 completed an online survey. Almost all reported that their participation in the FHF program was helpful or very helpful in training them to work with high-risk children and families, diverse communities, multiple systems, and other professionals. Qualitative analyses of mentors' responses to open-ended questions yielded several salient themes. (Contains 2 tables.)
