The DET is recognized by a growing number of universities and institutions around the world as evidence of English language proficiency. Additionally, the test can be taken from anywhere with a stable internet connection and a computer equipped with a webcam. One of the unique features of the DET is that it uses artificial intelligence (AI) to adapt to a test-taker's ability level in real-time, ensuring that the test accurately reflects their language proficiency. The test uses a combination of multiple-choice questions, fill-in-the-blank questions, and short-answer questions to assess a test-taker's language ability. It measures proficiency in English across the four language skills: reading, writing, listening, and speaking. The test is delivered entirely online and takes approximately one hour to complete.

It is a fast, convenient, and affordable alternative to traditional English proficiency tests such as TOEFL and IELTS. The Duolingo English Test (DET) is an online English language proficiency test designed to measure the English language skills of non-native speakers.
