The ROTC/Army Career Commitment Model focused on the process of career commitment during the young adult years by examining the career path of an Army officer via the ROTC route. Research questions were related to who joins ROTC and why, who remains as a career Army officer and why, and background factors which increase or decrease commitment to an Army career. Questionnaires were circulated among a stratified random sample of 1,089 high school students, 1,633 college students (754 ROTC; 879 non-ROTC), and 634 ROTC-graduate Army officers in the period of obligated Army service. Some conclusions, based on statistical analysis, focus on: differences between ROTC cadets and classmates in demographic background, aptitudes, social environment, and socio-psychological profile (differences becoming greater with time); different factors impinging on commitment at different stages of the career commitment process; early exposure to a career path increasing subsequent participation/commitment; intrinsic, free initial motivation in joining ROTC increasing the likelihood of subsequent ROTC/Army commitment; ROTC college experience indirectly affecting commitment; a sharp break in commitment between college and immediate post-college career stages; and differences in career commitment processes of black/white Army officers.
