RMS unstintingly supports its students’ associative activities, in particular by making dedicated collaborators available and by financing associative projects.

Taking part in associative life is an essential complement to any degree course.
Many students are involved in managing associations, so helping to develop their spirit of enterprise, their dynamism and their sense of responsibility. Such initiatives are of great help when it comes to professional integration.

Over thirty student associations exist side by side at RMS every year.
Each program has its Bureau des Eleves (BDE – students’ office), and RMS also has a Bureau de l'International (BDI), a Bureau des Arts (BDA) and a Bureau des Sports (BDS), alongside numerous creative and entrepreneurial activities and theme-based associations.

Here are a few examples of some importants events organizedevery year by students at RMS and in Reims:
- Fashion shows (Ethic business, lingerie, ...)
- Theatre plays, musicals, ...
