Application Process: 


Each year in October, the International Affairs Office collects the internship subjects from the laboratories for the following year. The internship subjects are then published at the end of November on the website. Partner institutions are informed of the opening of the application session.

Applications that have been pre-selected by partner institutions will be given priority. To find out if your institution is a partner of the program, please contact the international relations or mobility office of your institution. If your application is part of an existing collaboration with an Ecole Polytechnique researcher or laboratory, please indicate this clearly in your cover letter and choose the subject code SSDS. Applicants should indicate a maximum of three internship topics of interest for which they meet the criteria of level and profile, ranked in order of preference.

Between the end of January and the end of February, the applications are evaluated by a committee composed of representatives from the International Affairs Office and Directorate for Academic Affairs and Research. The selection criteria are based on the applicant's academic profile and motivation. More precise criteria of level or academic prerequisites are communicated in each subject description. The committee reserves the right to accept or reject an application. Candidates may be contacted by the supervisors for interviews at a distance or by email.   

Accepted applicants will be informed by email at the beginning of March and finalize the details of their stay at l’X with our support (visa, gratification, exact dates and duration of the internship).
The internship program is intended for international students. You may be asked to provide a school certificate including the period of the internship to validate your admission.  If you are in your final year of study, please provide us with a certificate proving that you have been admitted to the next year at your home university.
