What Duolingo score do you need for Trinity College Dublin?

The requirements refer to Duolingo integrated scores. You must share your score with the institution "Trinity College Dublin, The University of Dublin" from the Duolingo website.

For all proficiency tests, results must be issued within two years before the start of your course. Postgraduate applicants who completed a primary degree through English may request an exemption, which is only considered once the application is otherwise complete.

For comparison, the same page sets IELTS Academic at 6.5 overall with 6.0 in each band for Band B, and 7.0 with 6.5 in each band for Band C.

Applicants to undergraduate or postgraduate courses who do not meet the band requirement can apply for the CELLT Pre-Sessional Summer Programme, which itself accepts Duolingo 105 with 90 in each subscore. The Trinity International Foundation Programme is another route, from 80 overall.

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