Career change of young talent aggravates human resource shortages in various industries and the analysis of vocational commitment during the educational phase becomes paramount. Knowledge transfer modes and dynamics in the education of young professionals can influence their vocation or "calling" in the sector they are specialising for. With the background of the knowledge-based view, the goal of this study is to identify knowledge transfer-related aspects of education that exert a relevant influence on apprentices' vocational commitment. The findings of the study of 331 hospitality apprentices in Bavaria, Germany, reveal that both academic sources and firm sources in the apprenticeship-based, also called dual, educational system affect the vocational commitment of apprentices. Specifically, the satisfaction with the training in the educational centre, the existence of organisational mentorship, and a personalised training system in the firm significantly affect vocational commitment after the educational stage. Consequently, educators along with mentors and managers in the partner firms can help enhance their students' vocational commitment and potentially decrease their likelihood of leaving a sector.
