This correlational study sought to measure the relationships between sense of belonging and support received in peer mentoring programs for self-identified Latinx/a/o college students. Latinx/a/o college students faced discrimination, oppression, and marginalization in colleges and universities, which hinder their sense of belonging. There were four research questions that guided this study asking about the correlational and statistically significant, if any, between sense of belonging and overall support received in peer mentoring programs, sense of belonging and the three types of support: emotional and psychological, career degree, and academic subject knowledge; the correlation between sense of belonging and the length of time mentees participated in the program. It also asked about, if any, statistically significant correlation between sense of belonging and involvement in Latinx/a/o based services and programs.
