It is unknown whether social presence in internet-based MBA courses enhances students’ career success. This study examined general self-efficacy and goal orientation mediation models to determine what strengthens MBA students’ social presence and their career planning self-confidence. Data included 278 online MBA students in an AACSB-accredited college of business. The regression analyses demonstrated that perceived general self-efficacy and goal orientation related to students’ career planning self-confidence. The mediation analyses revealed that internet self-efficacy, perceived general self-efficacy, and goal orientation had an indirect mediating effect on social presence and career planning. Implications are offered for business communication educators.
