Community-based sociolinguistic corpora are collections of informal interviews with community members who comprise an important dataset in sociolinguistics. Although some scholars have involved students in developing sociolinguistic corpora, few studies have examined students’ perspectives on these projects. Furthermore, very few studies examine the perceptions of underrepresented college students who are themselves members of the surrounding community. The present study analyzes the perceptions of students involved in community-engaged scholarship (CES) courses at the University of Texas Rio Grande Valley on the U.S.–Mexico border. In these CES courses, predominantly Mexican American students contribute to the documentation of language in South Texas through the Corpus Bilingüe del Valle (Christoffersen & Bessett, 2019). A qualitative analysis of 38 student responses reveals six significant themes: a greater knowledge of transcription, increased connection with one’s own community, enhanced understanding from experiential learning and research experience, development of professional skills, a heightened appreciation of local language varieties, and pride in participating in a large-scale research project. These responses demonstrate the benefits of CES and serve to encourage sociolinguists to incorporate community-based corpora development in linguistics and language classes. More broadly, the results highlight the importance and impact of CES experiences for underrepresented college students, especially those incorporating course-based undergraduate research experiences.
