Sciences de l'Homme et de la Société ED SHS
Sciences et technologies de l'information et de la communication (STIC)
Sciences de l'environnement d'Ile-de-France
Sciences mécaniques et énergétiques, matériaux et géosciences - SMEMAG

Every PhD Student at Ecole Polytechnique has a funding covering his/her salary for the entire duration of his/her PhD.

More than 25% of the PhD students at École Polytechnique are doing their PhD in partnership with a company either under the industry research partnership scheme (so called CIFRE) or thanks to a scientific collaboration between their laboratory and a Company, from start-up and small businesses to big size companies.

More than 40% of our PhD Students are international Students coming from more than 45 different countries and 25% are women.
Finally, 60% of our PhD Students had a connection with École Polytechnique before starting their PhD either as a student in the Ingenieur or Master degrees or through a research internship in one of our laboratory.
3 years after obtaining their degree, 99% of our Doctors are under employment.

At École Polytechnique, the Graduate School gives assistance to the PhD Students with every aspects of their training and life on campus, from information prior to formal application to graduation and takes care of the training quality control.
