As an increasing number of students take online courses, lower completion rates in these online courses have created a crisis of attrition and turned the reversal of dwindling retention and graduation rates into a national priority. This descriptive quantitative study with "de facto" data investigated a subset of undergraduate online courses from an education-based program at a large R1 school in the Northeast and the role of student factors in successful online undergraduate course completion over a three-year period to determine whether a change in the successful course completion rate or student factors associated with successful course completion during the emergent pandemic could be found. The research indicated that two student factors were associated with successful course completion in all the study semesters: grade point average (GPA) category and enrollment in the minor course of study. Two student factors, age range and student class standing, were associated with successful course completion in spring 2018 and 2020 semesters. Race was associated with successful course completion in the spring 2019 semester only. Gender was not associated with differences in successful course completion in any of the semesters. The investigation showed that rates of successful course completion of these undergraduate online courses were similar before and during the emergent pandemic. During the emergent pandemic in spring 2020, the pattern of student factors associated with successful course completion mirrored that of spring 2018 semester. Having higher successful course completion rates should help increase both retention and graduation rates, both national priorities. This study also sets up future qualitative research identify individual circumstances and needed supports for successfully completing courses.
