Our school, Pasteur Mont Roland High school, has a great experience of mobility with traineeships and we wish to offer our students a professional and personal experience in a setting outside our school. We have sent our students for traineeships abroad since 2002 thanks to our headmaster and teaching staff who actively support and encourage this European openness that constitutes an undeniable asset. This mobility abroad develops our students’ personal, professional and cultural skills. Our goal is to offer our students a European openness allowing them to strengthen their professional skills, to develop some abilities such as adaptability to new working methods, flexibility, open-mindedness and independence in order to make their employability easier on the international job market. Traineeships are mainly intended for our students of the DMA training course (art degree) with the option “costume designer”. This specific training course aims at preparing our students to work as costume designers/makers for the theater, the cinema and other live shows with all the related constraints such as mobility, creative spirit, knowledge of costume history and textiles and the making of historical and contemporary costumes. For other short training courses of our school, an internship of 9 consecutive weeks is unfortunately not compatible with their skills base. This project involved eight students of DMA diploma and one member of the teaching staff from this same department. Our students, mainly young women, are in their first year of DMA training and for most of them, this traineeship represented a first professional experience abroad. Mobilities took place in Belgium, Spain, Czech Republic, Austria and Luxemburg. Our students went to international workshops for theater costumes or national operas, thus allowing them to combine professional and cultural goals. Thanks to our lasting partnerships in these countries, the receiving enterprises took our students again without any problem. Concerning training mobility, the teacher went to England where she had theopportunity to develop her skills about the making of historical costumes in order to propose our students new knowledge and expertise in this field. Back from the traineeship, all the participants recognized they had acquired new skills in their own professional fields but they have especially developed new personal abilities like independence, responsibility, interpersonal skills and self-confidence. We noticed these experiences have led to personal and professional value of our students.
