Can your bachelor's and master's be in different fields?

Yes, it is possible — but the master's programme's admission requirements decide. In Germany each university and programme sets its own requirements, and the subject of your bachelor's is one of the key ones.

#What the university checks

• Subject fit: do the courses in your bachelor's cover the foundation the master's expects?
• Your grade, language proof and the required documents.
• The university reviews your degree and transcript individually and makes the final decision.

#No fixed national rule

• There is no public, fixed list of which bachelor's counts as suitable for which master's.
• There is also no Germany-wide GPA, NC or language threshold.
• Two programmes with the same name can ask for different backgrounds.

#How to approach it

• Read the programme's admission requirements (Zulassungsvoraussetzungen) and compare them course by course with your transcript.
• If you are unsure, contact the programme's advisory office with your transcript before applying.
• Check requirements in the DAAD admission database and on the university's own page.
• For the institution side, check in anabin whether your university is H+; H+ is only a prerequisite, not admission.
