Purpose: Social support may be provided by undergraduate students' family and friends and by other members of the campus community, including faculty. The purpose of this review article was to review the existing literature about the roles of faculty members as advisors, mentors, and gatekeepers who provide social support for undergraduate students. Social support is a buffer for stress, and current undergraduate students are more stressed than their predecessors. Method: The study is a narrative review of the literature about faculty as advisors, mentors, and gatekeepers. The concept of social support and its relationship to students' stress is explored, followed by a discussion of faculty advisors' roles, knowledge, and skills and a synthesis of literature about prescriptive, developmental, praxis, and appreciative advising. A discussion of faculty as mentors who focus on students' experiences before, during, and after college and as gatekeepers who look for signs of students in distress concludes the review. Conclusions: Faculty may provide social support to students inside and outside the classroom as advisors, mentors, and gatekeepers. Assuming these roles means faculty must consider students as whole people who have needs and experiences beyond academics. Students' stress was clear in the literature before COVID-19, and their concerns and needs are exacerbated during the pandemic. Additional research is needed to identify effective advising and mentoring programs for communication sciences and disorders undergraduate students. Increased institutional support for and recognition of the time, resources, and training faculty need to serve in this expanded role is also critical as faculty members attempt to manage their own stress.
