The project was originally sponsored by von Ahn's MacArthur fellowship and a National Science Foundation grant. Hacker (co-founder and current CTO of Duolingo) believed that "free education will really change the world" and wanted to supply people an outlet to do so. A driving motivation was Von Ahn's upbringing in Guatemala, where he saw how expensive it was for people in his community to learn English. Von Ahn had sold his second company, reCAPTCHA, to Google and, with Hacker, wanted to work on something related to education. The idea for Duolingo was initiated at the end of 2009 in Pittsburgh by Carnegie Mellon University professor Luis von Ahn and his Swiss-born post-graduate student Severin Hacker. Its optional premium service, Super Duolingo, is ad-free and has more features. The company uses a freemium model, with over 500 million registered users. It also offers the Duolingo English Test certification program Duolingo ABC, a literacy app for children and Duolingo Math, an elementary-level math app (currently only for iOS). It offers courses on over 40 languages, from popular languages such as English and Spanish, to less commonly studied languages such as Welsh, Irish and Swahili.

We will continue to use its incredible capabilities to improve the lives of learners worldwide as part of our mission to make high-quality education available to everyone on the planet.Online education, Professional certificationĭuolingo, Duolingo Math, Duolingo ABC, Duolingo English Test But we have a lot of experience working with this powerful technology. In times to come, generative AI will continue to evolve in ways we can’t yet imagine. Moreover, secure at-home testing has made it accessible to a broader audience.Ĭonsidering how AI and DET work hand-in-glove, the brand has established a set of Responsible AI standards to support the assessment scientists who use AI to develop the test and build a valid argument for digital-first assessment and support claims for the DET about validity, reliability, and fairness. The test’s length is reduced through computer-adaptive technology, while automated item generation and scoring have made it more cost-effective. DET’s test bank is so large that any question appears in only 0.2% of all tests.Īccessibility: Since its inception, DET has employed AI to replicate all the functions of a conventional paper-based, in-person test in half the time and at less than half the cost. Its AI-powered “Item Factory” blends human expertise with technological innovation, allowing it to constantly generate new test items, ensuring that repeat test takers cannot encounter the same test item. As part of DET’s digital-first approach to test development, it has combined human expertise with the power of AI for a comprehensive approach to exam supervision. Unprecedented security technology, including a 1:2 candidate-to-proctor ratio, where every proctor has access to AI tools monitoring dozens of biometrics and behavioral data categories. The latest technology then automatically grades test-taker answers, which can be complex and are not simple multiple-choice items, and finally synthesizes all of this into a final test score and helps make the human review and proctoring stage more stable and efficient before test scores are certified and released.ĭigital security: DET’s rigorous security protocols ensure the test is highly secure. In particular, the test uses these technologies to:ĭesigning customised test-taking experiences: The test uses AI to assess the language ability required for each test item by automatically aligning them to proficiency levels in the CEFR subsequently adaptively administers items for every test, which makes it both shorter and more secure. The Duolingo English Test is the first and only high-stakes test to use AI and machine learning end-to-end at every process step. For instance, the Duolingo English Test (DET) is a digital-first assessment that uses human-in-the-loop AI for test design, measurement, and much more. Teachers are using AI to personalise learning experiences for students, create customised curricula, and improve student outcomes. Artificial intelligence (AI) has touched almost every aspect of our lives, from how we communicate to how we work, shop, travel, and even learn.
