The Duolingo English Test (DET) is an online English language proficiency exam designed to assess the skills of non-native speakers. It is particularly popular for its convenience and affordability, offering an alternative to traditional English tests like TOEFL and IELTS. The DET is accepted by a growing number of universities and institutions around the world, especially in the U.S., Canada, and the UK.
The test evaluates four primary language skills: reading, listening, speaking, and writing. Unlike many other standardized tests, the Duolingo English Test is adaptive, meaning the difficulty of questions adjusts based on the test-taker's performance. This adaptive nature allows for a shorter test duration, typically around 60 minutes, while still providing a comprehensive assessment of language proficiency.
