The Latinx population is increasing in the United States and within Higher Education. Despite this increase, there remains a lower completion rate of Latinx students completing a higher education degree. Higher education institutions have worked hard to achieve upward mobility and try to close the achievement gap by providing students with resources like Student Support Services (SSS) for low-income, first generation, and students with disability. The purpose of this study was to examine the experiences of nine Latinx students at an HSI who were directly involved with SSS. The research question was: How do college Latinx students at a Hispanic Serving Institution (HSI) relate their lived experience of Student Support Services (SSS) to their academic success? The theoretical framework used was Astin's Input-Environment-Outcome Model, utilizing an Interpretative Phenomenological Analysis. Participants were selected based on purposive sampling. The researcher established contact with the TRIO director, a recruitment email was sent, participants contacted the researcher, and semi-structured interviews were recorded and transcribed. The researcher conducted two cycles of coding: value coding and axial coding. Common themes included first generation (Background); access to information, alienation, management, lack of mentors/role models, economic hardships, (Challenges-Before TRIO); networking (Access to TRIO); and academic success, mentoring, and tutoring (After TRIO). Sub-themes included ancestry, language, proper study spaces, and cultural expectations at home. Recommendations for future practice include better advertisement for TRIO and inform students of the qualifications required to be a TRIO participant. Recommendations for future research include to have the researcher be of a different background and have a larger pool of participants; the before and after effect of being involved with TRIO and the support networks established were key discoveries to this study.
