To apply for a programme at the AUAS, go to Studielink. If you live in the Netherlands, you need a DigiD to access Studielink. If you live abroad, you can apply without a DigiD (see instructions in Studielink). For your application, you will need to enter the CROHO name and code for the programme. For this programme, this is International Business, 30029.
After you submit your enrolment in Studielink, you will receive an invitation by email for the study check from mid-January (not sooner). This will let you know whether you understand what the degree programme is about and provide you with options for what you can do next.
