Arm Internships require you to be enrolled in a higher education degree.

French Law requires students to complete an internship agreement (Convention de Stage). This is a tripartite agreement signed by the student, their home university and host organization, that facilitates an internship in France. It is the contract defining all the essential points of the internship: duration, missions, remuneration and benefits, insurance in the event of an accident, etc.

It is preferable that Arm’s own template of the agreement is used. Successful applicants will be required to provide contact details of the appropriate university representatives in order to have the agreement signed.
