None, the programme is entirely in English. If an application form asks for your German skills, this is only because of other study programmes; your answer does not affect the chances of getting admitted.
Level B2 of the Common European Framework of Reference for Languages. You will have to prove your English skills informally, no formal certificate like TOEFL or IELTS is required. E.g., having completed high school in Austria (AHS, BHS) or a bachelor programme offered in English usually suffices as proof.
Follow the instructions on the web page "Admission to a master degree programme". Please submit your application in time, as the admission procedure may take two months or even longer.
Your application is processed in two stages. First, the admission office checks whether your application meets certain formal requirements. You need a degree on level 6 (bachelor) or higher in the European Qualifications Framework, and it should have been awarded by a recognized institution (classified as "H+" in ANABIN). Depending on your country of origin, further conditions may apply.
In the second step we check whether the documents you have supplied with the application (like degrees, transcripts, certificates, references from employers) allow us to conclude that your expertise in computer science, economics, business informatics, and mathematics suffices to follow the master courses successfully.
At the moment, there is no restriction on the number of students admitted per term. You don't have to compete against other applicants for a limited number of places.
If you have completed a bachelor in Wirtschaftsinformatik at TU Wien you will be admitted without further conditions.
Otherwise we check, based on the documents that you have provided with your application, whether you have the necessary prerequisites for mastering the courses in the programme. If you have, you will be admitted without further conditions. If not, we compile a list of missing prerequisites. If they sum up to a term (half a year) or less, you will be admitted under the condition that you do some extra courses. You don't have to do them in advance, but can do them side-by-side with the regular master programme, as we check their completion only at the end of your studies here.
If the missing prerequisites exceed a full term, we have to reject your application.
We check your documents (like transcripts and certificates) for expertise in the following four areas.
The numbers in parentheses indicate the extent of the area, measured in credits according to the European Credit Transfer System. One Ects corresponds to 25 hours of student work, 60 Ects correspond to the work load of a year.
We are not picky about single ECTS credits, but you need a solid foundation in these four areas to be admitted without further conditions. If you lack some of these foundations (up to 30 Ects), you can be admitted under the condition that you do some extra courses to make up for it. If you lack considerably more, you will not be admitted.
Regarding admission procedure, forms, deadlines, tuition fees, first read the document Admission to a master degree programme. For questions on formalities not answered there, contact the admission office: studienabteilung@zv.tuwien.ac.at; note that the answer may take several days.
For information on the courses in Business Informatics, see the online information system TISS.
The curriculum is the authoritative, legally binding document. It's written in a mixture of German and English and probably a bit cumbersome to read.
For questions that are answered neither in these FAQs nor in the documents listed above, please contact the faculty of informatics: dekanat@informatik.tuwien.ac.at; note that the answer may take several days.
