It is issued under the United Nations Economic Commission for Europe (UNECE) Inland Transport Committee Working Party on Inland Water Transport Resolution 40. It is this resolution which details how and to whom the ICC may be issued, the syllabus requirements, the layout of the certificate and it also lists the countries which have notified the UNECE Secretariat that they have accepted the resolution.

Students who wish to acquire this certificate are required to have a minimum of RYA Day Skipper certificate prior to application or pass an ICC assessment.
