Duolingo English Test

The Duolingo English Test (DET) is a standardized test of English language (similar to TOEFL, IELTS, and TOEIC) but designed to be internet first rather than paper based. DET was developed by Duolingo and grew in popularity and acceptance at universities during the COVID-19 pandemic.[1] The test is used by over 4,000 university admissions offices including Harvard, Stanford, MIT, and Yale.[2] Ireland accepts the test as part of its student visa program.[3] DET is an online, adaptive test which means it uses AI to adapt the difficulty of the test as you progress.[3] Universities in the UK such as the London School of Economics, Imperial College London, Kingston University, University of Southampton, Middlesex University also accept the Duolingo test.[4]

The Duolingo English Test is entirely computer-based and can be taken from any location with an internet connection. The test is scored on a scale of 10-160, with scores above 120 considered to be proficient in English. The test is adaptive, which means that the difficulty level of the questions adjusts to the test-taker's ability level.

One of the main advantages of the Duolingo English Test is its convenience and accessibility. Test-takers can take the test at any time, from anywhere in the world, and receive their results within 48 hours. Additionally, the test is affordable and typically costs less than other English proficiency tests such as TOEFL or IELTS.
