While it is possible to nominate a single candidate, the Court encourages universities to propose more than one nominee. Universities are strongly encouraged to limit nominations to candidates who have shown excellent results in their legal studies and who have demonstrated an interest in public international law through their studies, publications and/or work experience. The official languages of the Court are English and French, and participants must have excellent reading, writing and oral skills in at least one of them. A working knowledge of the second official language is an asset.
To be eligible, candidates should be 31 years of age or younger at the time the programme begins. This requirement may be waived in special circumstances. In making its selection, the Court seeks candidates of diverse nationalities.
The Court does not accept applications from individuals.
