Apprenticeships can offer apprentices, their teacher-tutors and business apprenticeship supervisors experiences that are rich in knowledge. The Success of Apprenticeships presents the observations and opinions of 48 actors regarding apprenticeships. These testimonies recount how apprenticeships allowed them to improve their expertise, their professional practices and their organization skills. This book also examines how their interactions in the work/study process allowed them not only to develop the skills of apprentices, but also the skills of those who accompanied them – the teacher-tutors and the business apprenticeships supervisors. The creation of an authentic community of apprentices subscribes to the formation of an ecosystem of learning, in which each individual harvests fruits in terms of the development of their personal abilities.
