The Erasmus project at Choiseul high school has two main objectives: support and help for students who have to complete an internship in a company. The students concerned are from STS and DN MADE courses (national diploma in crafts and design). In fact, all of these courses are fully concerned by the development of their international activities. For students, it is about discovering, participating and integrating into a multicultural world (certainly within the company) through their host country. We work on the intercultural approach to the construction of our societies and this experience abroad allows them to concretize the theoretical approach seen in different courses of their school curriculum. The evaluation of this internship, of this experience, is carried out by a written report then by an oral defense before a jury which assesses the level of involvement and actions carried out by the candidate. This results in obtaining a final grade which contributes to the award of the diploma prepared by the student.
