The total duration of internships or periods of work experience carried out by the same intern at the same host organisation must not exceed six months per academic year. If an intern completes two internships totalling 10 months at the same host organisation during the same academic year, the relationship between the intern and the host organisation must be reclassified as an employment contract.

Furthermore, successive hosting of trainees under different internship agreements to carry out internships in the same position is only possible after a waiting period equal to one-third of the duration of the previous internship. If the legal waiting period between each internship carried out by the trainee in the same position has not been observed, the relationship must also be reclassified as an employment contract.
