The Polytech'13 project is carried out by the Polytech schools which is the first network of engineering schools with 18,000 students and more than 4,000 annual graduates with "Ingénieur" degree (MSc in Engineering). The target group for the action is obviously all the engineer students of the Polytech schools. Within the education and training curriculum of engineers in the Polytech schools, in accordance with the rules established by the Commission des Titres d'Ingénieurs (CIT), all students have the obligation to achieve three periods of internship and an international mobility over their 3 years engineering cycle. The project allows today to support mobility of engineering students to European companies as part of their compulsory internship periods and international mobility. This action is implemented successfully by the Polytech schools since 2008 and won a great interest and success for students and staff teachers/researchers. The project helped to establish links with more than 750 European companies. In the previous edition, completeness of the funding was used for 585 mobility students.
