The purpose of this study was to examine what barriers to successful completion single mothers encountered in postsecondary education; and what support structures facilitated their success. Using qualitative research methods that included interviews, observations, and document analysis, this study discovered that single mothers needed both institutional and personal support structures in place to be successful in higher education. Institutional support structures included adequate advisement, program flexibility, on campus child care, and extended hours of operation for student support offices. Personal support structures included child care, financial capabilities, and sufficient time. The single mothers described how they were able to overcome obstacles experienced when the elements of both support structures were in place, ultimately helping them build resiliency.
