Corbon High School is a Vocational school specialized in business and administration. Last year, an European Section was opened for the classes which prepared a professional High School Leaving Exam in Business (''Bac Pro Commerce''). The participants involved in this project are from both classes: ''Première'' and ''Terminale'' Bac Pro Commerce. The students are prepared to become shop-assistants. The economic insertion of these students is subject to the difficult economic environmental pressure, that is to say hypercompetition. This project allows the participants to acquire and use some knowledge, some skills and some qualifications in order to ease their personal and professional development and their participation to the European job market. Learning foreign languages is a very important process in the educational field and life training. We would like to offer our students a five week European mobility work experience: one week of intensive English classes and four weeks of company placement. The activities of this mobility are on the one hand cultural (visiting the Waterfront National Museum, discovering the Natural Richness of the area) and on the other hand professional(discovering the commercial structure of the region, realizing their training period according to the framework of the diploma: animation, management and selling). We are going to assess the participants' skills to mobilize themselves around a project by research work and by preparing their trip. The work quality will be a clue to measure the degree of their individual and collective involvement. For assessing the work and the degree of students' new professional and environmental integration the service providers will use the assessment grid (annexe 1). At the end of the training period, the DNL teacher comes back to the company placement and will assess the trainee according to the framework of the diploma. The students selection is an important factor to succeed in achieving this project. The main quality requirements are the language skills and the motivation degree. The annual assessment bases on the following: - annual measure of the attractivity of the European class particularly on middle school public - annual reporting of the members of the European classes team during the high school boarding The success of the project will have a positive impact on the students and also on the high school. In fact, during their training period, the quality of the students' work will contribute not only to value the linguistic and professional topics but also to value the high school image. This will lead to a partnership project with the high schools and companies located in the trainees' host towns.
