While scholars have used Schlossberg's transition theory for more than 35 years to study college-to-work transition, researchers have yet to establish if there are meaningful differences in the perceptions of traditional and nontraditional college students regarding transition preparedness from college-to-work. Following the career transition model, this quantitative study was conducted to compare traditional and nontraditional college students' perceptions of transition preparedness, specifically the concepts of readiness, confidence, control, perceived support, and decision independence. The nontraditional students in this study were military veterans. The dependent variables were measured by the Career Transition Inventory (CTI) survey. Participants were selected via a web-based method until 100 traditional and 100 nontraditional students were surveyed. The data were examined with multivariate analysis of variance and multivariate analysis of covariance. There were significant differences found in perceived transition preparedness. The CTI measure decision independence was significantly lower among nontraditional veteran students. Whereas, the CTI measure confidence was significantly higher among nontraditional nonveteran students. Based on the results of this study, three recommendations were made. If these recommendations are followed, this study can make a positive social change and might increase the probability of improving the career and academic transition services from college-to-work for non-traditional undergraduate veteran students.
