The apprenticeship of a profession in Switzerland was designed for young people who left compulsory school around the age of 15. Many of those who have benefited from this apprenticeship now have a very specialized job and often require managerial skills to lead a team. In this study, we wanted to explore the notion of management apprenticeship for adults. Our fieldwork (20 semi-directive interviews) focuses on former students of our Master of Advanced Studies in Business administered by the University of Applied Sciences Western Switzerland over the past 10 years. This program has the particularity that 40% of our students do not need a BSc to obtain a postgraduate diploma (MAS) in management. Our findings help to explain why and how this mix of graduate and non-graduate students in a continuing education context offers adults identical assets to traditional apprenticeship with the prospect of occupying a managerial position in their organization.
