What Duolingo score do you need for Esade?

Both pages say language test scores are valid for two years. Neither page sets Duolingo subscores or gives instructions for sending Duolingo results, so ask the admissions team how they want to receive it.

If your bachelor's degree (at least 120 ECTS, or three academic years for MSc) was taught in English, you can send a diploma supplement or university certificate stating the language of instruction instead. CEMS MIM candidates cannot use secondary education as proof of English.

For comparison, the MSc page asks for IELTS Academic 7.0 where it asks for Duolingo 130.

The pages list no conditional entry or pre-sessional route for English. The alternatives are another accepted test at its own minimum, such as PTE Academic 68 or Cambridge Advanced at B+, or the English-taught degree exemption.

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