What Duolingo score do you need for the Hertie School?

The test may not be older than two years. You can apply without English results and submit them later at no disadvantage, but any offer stays conditional until you meet the requirement, and the deadline for English results is 1 June. The admissions page asks you to send the certificate to the admissions team by email. The blog says the school accepts two at-home options, the TOEFL iBT Special Home Edition and the Duolingo English Test, while encouraging in-person exams.

For comparison, the same pages set IELTS at 7.0 overall with 7.0 in writing, so IELTS has a writing floor and Duolingo does not.

Non-native speakers can waive the test with an undergraduate degree from an institution where the official language of instruction is English, shown by an officially stamped letter from the university. The blog says English-taught master's degrees do not count. Short-term study abroad, au-pair stays and language school certificates are not accepted in place of a test.

Requirements vary by programme and change between admissions cycles. The score that binds you is the one on your Hertie School programme page and in your offer letter, so check it there before you book a test.
