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 someone films him to send the video to the teachers. The goal of this is to promote self-confidence, speaking, and the scientist reflexion which are important qualities for the future engineer.
* An international program in a multicultural environment: many students with different cultures and two foreign languages to learn. At the beginning of the formation, students can participate in an English language session for one week in order to learn the fundamentals of the scientific English. Insertions travels are organised at the end of the first year in Germany or in England. The students will participate in lectures and lab work in a foreign university. Most of the time the foreign students come from China.
