According to the IHL Degree Regulations § 15, students in the Master’s Programme must undertake an internship in the third semester. The internship should last for 450 h (e.g 3 month / about 37,5 hours per week). 

If you are, or have already been, working in an organisation in the human rights field or other field related to the IHL programme, it may be possible for this to be accredited as equivalent to the required internship. (Please note: The final determination of equivalence will be made by the IHL Academic Board. Such a determination is not, however, the final satisfaction of the internship requirement: it is also necessary in such cases to submit both the ‘Internship ― Student Report’ and the ‘Internship — Supervisor Report’ as required in all cases under § 20 Examinations Regulations.)
