The Duolingo English Test (DET) is a standardized test of the English language designed to be internet-based rather than paper-based. DET is an adaptive test that uses an algorithm to adapt the difficulty of the test to the test-taker. It was developed by Duolingo in 2014 as Test Center and grew in popularity and acceptance at universities during the COVID-19 pandemic. The test is used by around 5,500 university admissions offices, including Harvard, Stanford, MIT, and Yale. Ireland accepts the test as part of its student visa program. Universities in the United Kingdom, such as the London School of Economics, Imperial College London, Kingston University, the University of Southampton, and Middlesex University, also accept the Duolingo test.

The Duolingo English Test is scored on a scale of 10–160, with scores above 120 considering the test taker to be proficient in English. The test costs less than TOEFL or IELTS.
