Despite the increase in enrollment of first-generation college students at four-year institutions, this student population was more than twice as likely to drop out before their sophomore year compared to their non-first-generation peers. Specifically, a subgroup of first-generation college students that has been identified as greatly disadvantaged yet received little attention in the literature are those from migrant and seasonal farm worker (MSFW) backgrounds. The unique educational needs and risk factors of these students demand that postsecondary institutions develop resources and support services in an effort to better serve them. While the literature identified co-curricular involvement as a factor contributing to the sense of belonging and retention of college students, it failed to acknowledge the unique experiences of minoritized and/or marginalized student populations. This study introduced and supported the argument that merely offering involvement opportunities did not work for this student population, and suggested that institutional agents who interacted or worked closely with them had to facilitate validating conversations and build close relationships early on to encourage co-curricular involvement. The innovation supported first-generation MSFW students’ participation and engagement in conversations and activities in an effort to help enrich their experiences, and enhance their overall sense of belonging and college retention. The innovation demonstrated the many benefits stemming from first-generation MSFW students’ participation in a peer mentor program, and allowed for collection of feedback in an effort to better serve this student population. Further, based on the results of this study, the innovation may have positive impacts on the sense of belonging and college retention of first-generation MSFW students.
