What TOEFL score do you need for Yonsei University?

The graduate guide says TOEFL scores must come from tests taken on or after 4 December 2024. The Home Edition and MyBest scores are accepted within that period, but TOEFL ITP and TOEFL Essentials are treated as not submitted, except ITP tests run by Yonsei itself. You upload a PDF of the online score printout with your application; the guide says score reporting is not accepted, and a score below the department minimum counts as not submitted.

Underwood International College gives ETS institution code 9893 for scores sent directly to Yonsei, and asks applicants who do so to email the admissions office with their name and test date.

In the same graduate guide, most departments list IELTS 5.5, and some list 6.0.

The graduate guide accepts substitute documents in departments that allow them: nationality of the US, UK, Ireland, Canada, Australia, New Zealand or South Africa, or completion of a whole school or degree programme in one of those countries, or a full degree taught in English elsewhere with an official letter. Applicants can also apply through the Korean route with the TOPIK level their department sets.

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