This study examines the composition of informal mentoring networks utilized by low-income urban adolescent girls with healthcare college and career aspirations. 60 ethnically diverse students in their third year of secondary school were included in this study. These students participated in a survey about their future educational and career plans and the persons providing support for their future plans. Results suggest that diversely composed, or multi-context, informal mentoring networks are effective in supporting adolescents in their educational and career pursuits.
