This nonexperimental quantitative descriptive-correlative research study was performed to describe the sources with the greatest influence on the participants' decision to enroll in a postsecondary educational program with the intent of working toward a career in health information management. Participants were asked, "Which sources have the greatest influence on an individual's decision to enroll in a postsecondary educational program with the intent of working toward a career in health information management (HIM)?" The study population was composed of matriculated students enrolled in accredited postsecondary schools offering an undergraduate medical billing and coding program at a brick-and-mortar campus in a two-county area of a South Atlantic state. The study found that an environmental source, specifically career job opportunities, was statistically significant as the greatest source of influence for these participants. This research aims to support efforts to provide the health information management subsector of the healthcare industry with a sufficient number of trained professionals to fill the identified need for trained HIM professionals, particularly medical coding specialists
