have a Bachelor of science or an equivalent foreign degree. - After 2 years in CPI classes at Rennes (ENSCR), Lille (ENSCL), Clermont-Ferrand (ENSCCF) or in Strasbourg (ECPM: referred to the CPI classe's paragraph). → To enter the Second year, students can have access at the ECPM having an interview, with a Master M1 in Physics with a speciality in Polymers or materials. → Admission to the CP2i class in the ECPM, after the Baccalaureate, or an equivalent foreign degree for the international students. There is no competitive exam, but every student should submit their school results. Then there are interviews to evaluate the motivations with the people in charge of the Chem.I.St programme. Approximately 50 students are selected every year. There are nearly 20% international students. CP2I / Classe préparatoire intégrée internationale This class allows the students to gain admission to a school of the Fédération Gay Lussac (19 schools) after two years. These 2 years consist of studying engineer's trades in the domain of chemistry. There are 5 CPIs in France: Rennes, Clermont-Ferrand, Lille, Pau and Strasbourg at the ECPM The last one was opened at the start of the 2011-12 school year in Strasbourg. The speciality of this school is that it welcomes a large number of international students, as well as that 20% of the courses are delivered in English and 10% are delivered in German (optional). There are 50 students in each year. To gain admission to the CP2I: French students register on Admission Post-Bac and follow the steps. Students are selected on the basis of their academic record and a 20-minute interview. International students submit their dossiers directly to the school. International students are also selected on the basis of their academic record and an interview. General presentation of CPI-CHEM.I.ST : A strong scientific program: a major part of chemistry, physics and maths during the 2 years with a total, for the first year, of around 700 hours of scientific lesson. We must add Lab Work of this scientific formation, with a total of 102 hours for the first year. The CPI-CHEM.I.ST base of more practical work than in an intensive foundation degree, with high-quality laboratory. The program includes group work to develop the communication, the creativity around scientists projects. Moreover, in 2016, a "videxo" program was created. During, the "videxo" student solves a science problem on a board and in the same time
