The purpose of this case study was to identify characteristics of learners who completed their master's degrees online and to explore the reasons adult learners chose to enroll in a particular institution to complete their online master's degrees. As more postsecondary institutions explore the online environment, more research-based information is needed to assist leaders as they investigate adding online graduate degree programs. A modified Delphi study was used to guide the analysis of data gathered through a survey questionnaire. The survey questionnaire was completed by a sample population of Ed.S. learners enrolled in a small, private nonprofit Level V university in east Tennessee. The study revealed that most online learners enroll in private, for-profit institutions. The majority are White, adult females who are married. The institutional characteristics that most influenced the enrollment choice were a program format and duration that allowed learners to continue at their current jobs and maintain family routines.
