Most distance universities have adopted advising practices traditionally employed in on-campus institutions. Nonetheless, little is known about the role of academic advisers while guiding students with dis/abilities to engage and achieve success in online higher education. This study aimed to explore and analyze advisers' perspectives related to supporting the diversity of these students in a fully online university. We followed the methodology of a case study based on semi-structured interviews in which 14 advisers participated. Our findings show that even though advisers face challenges when advising online students with dis/abilities, they attempt to support them proactively by offering personalized tracking. A paradigm shift from a reactive to a proactive approach by adopting inclusive practices would greatly improve the inclusion of all learners. Online institutions could better support learners with dis/abilities by framing all processes in the universal design principles and promoting collaborative and coordinated work among advisers, faculty, and staff.
