This researcher examined three selected New York City community-based organizations' roles in student mentoring and the building of social capital. The methodology included focus group interviews, individual interviews, shadowing, and the collection of archival materials. The data were analyzed through pattern, theme and discrepancy analysis to explore the efficacy of the targeted mentoring models and the presence, if any, of social capital in these models. Findings: Each community-based organization deemed its mentees as a primary concern. Several different styles of mentoring were prevalent in each organization, which helped build congenial relationships between mentor and mentee. Resources were abundantly used by each organization through various activities scheduled during the course of the year evidenced through interviews and archival data. The three community-based organizations became "safe havens" for many of the mentees who had become participants in the three organizations through their individual schools. A lack in parental involvement was noted in all three community-based organizations with the underlying cause for such low percentages attributed to poverty. Administration, program managers and mentors from each organization, assumed roles as surrogate parents during their contracted schedules. Conclusions: These community-based organizations extended their resources through collaborative efforts. By becoming inclusive within the community areas the organizations serviced, each organization's social networking base increased. The partnerships created between the community-based organizations and other community entities allowed outside efforts to foster "bridging social capital." The student mentoring programs also benefitted from the partnerships in the forms of internships that led to jobs, educational credit, and exposure to outside professional networks. The collaborative relationships assisted each community-based organization to attain its mission. [The dissertation citations contained here are published with the permission of ProQuest LLC.
