How long is the Duolingo English Test?

Duolingo says test takers need about one uninterrupted hour. That includes onboarding and setup, the adaptive test, and the writing and speaking sample portion.

How many questions are on the DET?

DET does not have one fixed public question count. Duolingo describes it as adaptive in both difficulty and length, and the official frequency table gives ranges for several task types rather than one exact total.

When are DET results available?

Certified results are normally available within two days after completing the test. Duolingo also offers Faster Results, which can provide results within 12 hours when purchased.

Does this question bank copy official DET prompts?

No. These are original selected-response practice questions adapted to DET skills and task recognition. For the official adaptive experience and estimated score range, use Duolingo's free official practice test.
