It is compulsory to be in possession of an ICDL Skills Card, otherwise it is not possible to register for the ICDL exams.
The Skill Card is a digital document registered under the name of the Candidate, certifying enrollment in the entire ICDL Full Standard / ECDL Core or ICDL Advanced exam programs, in which the candidate’s personal information and the exams taken are registered.
In order to be allowed into the classroom and take the exam, it is sufficient to show your Bocconi card or an ID document.
