The Polytech13 project is carried by 13 Polytech schools which is the first network of engineering schools with 14000 students and more than 3200 annual graduates with Ingenious title (MSc in Engineering). In the education and training of engineers, in accordance with the rules established by the Commission des Titres d'Ingénieurs (CIT), students have the obligation to achieve three periods of internship and international mobility. The project allows today to support mobility of engineering students to European companies as part of their obligations to internship and international mobility. This action is implemented sucessfully by Polytech schools for more than 5 years and won a great success with students and staff teachers/researchers. The project helped to establish links with more than 550 European companies. As with the previous edition, completeness of the funding was used to 399 mobility students and 17 teaching mobilities. During these annual audits, CIT has put forth this program as a good practice to the 214 French engineering schools.
