The requirement depends on the language of instruction. For English-taught Master’s programs at TU Berlin, students usually need an IELTS score of around 6.5 or TOEFL scores approximately 90–100. For German-taught programs, proof of proficiency such as TestDaF level 4, DSH-2, or an equivalent C1 certificate is typically required. Even if you enroll in an English-medium program, having basic German skills can significantly improve job and internship opportunities in Berlin.
