To study a Master’s degree in the area of Business Administration, you should first hold an academic degree in this field, or - depending on the program’s specialization - first degrees from related fields such as Social Sciences, Urban Planning or Environmental Engineering may be accepted, too. Check on the program websites for more information. For most programs, entrance tests or interviews are not part of the admission process. Students are usually admitted based on their certificates (your first degree certificate, a transcript of records, proof of sufficient English skills [typically around B2 level]). You can also expect to have to include your CV, a letter of motivation and sometimes letters of reference. A few programs, especially those targeted at professionals such as various MBA programs, may also ask you to include GMAT scores to your application or prove that you have sufficient work experience.
