École Polytechnique typically has two main intakes: September (primary) and January (limited programs). Application deadlines vary by program and applicant origin. For September intake, deadlines usually fall between December and April of the same year. January intake deadlines often close by October of the previous year.
Master’s programs generally follow these timelines, while engineering cycles may differ. International students should apply earlier for visa processing. Exact dates are updated annually on the official website. Early applications are advised due to competitive selection. Some programs may have rolling admissions or additional rounds.
