Decades of research suggests that supportive faculty communication improves student retention and progression; however, most communication interventions occurred at on-site universities and were implemented briefly in one or several courses. In this article, we describe the outcomes of a consistent, personalized student outreach program implemented in every course and for students' entire tenure at a fully online university. In 2019, Western Governors University launched a student support program called Learner-Centered Faculty (LCF)--a paradigm that focuses on just-in-time, personalized, student-centered faculty support at scale. We evaluated the impact of LCF on student retention and course completion rates and found that LCF-based intervention improved retention and course completion generally and was particularly beneficial for certain groups of students. In the future, we will examine the mechanisms underlying LCF's success.
