The Duolingo English Test (DET) is structured into three main parts: Test Setup, an Adaptive Test, and a Writing and Speaking Test.1. Test Setup: This initial phase guides candidates through installing the app, logging in, and verifying camera and microphone functionality. It also includes identification and agreement to terms.2. Adaptive Test: Lasting 45 minutes, this section assesses speaking, writing, listening, and reading skills through various question types, such as selecting correct words, reading sentences aloud, answering short essays, describing images, and filling in missing letters. Upon completion, candidates receive a score between 10 and 160.3. Writing and Speaking Test: The final 10-minute section focuses on advanced writing and speaking abilities. Writing tasks may involve composing on a topic for 3-5 minutes or describing a significant person or event. Speaking tasks require detailed answers to specific questions.Candidates can take the DET multiple times, though a limit of two tests within 30 days applies. Over 1300 universities in the USA accept the Duolingo Test, including top institutions like Yale (min. 120), Harvard (min. 125), and MIT (min. 120).
