The developers of the Duolingo English Test publish extensively on their research in computer adaptive test-taking and engage widely with stakeholders in discussions regarding the requirements for security and psychometric quality. The clear benefit to candidates is the removal of barriers to test taking. The “take anywhere, anytime” ethos of the Duolingo English Test results in impressive time efficiencies, achieved through automated, adaptive selection of questions, tailored specifically to the candidate’s performance.
Use of AI to generate the test items is cutting edge. Subject matter experts leverage machine learning models to create a deep pool of items. As part of the question item generation process, all content is reviewed by a panel for fairness and bias. Test score reliability is checked through an analysis of repeat candidate results and an AI quality assurance system monitors each test administration. Ongoing research is undertaken to compare the validity of Duolingo English Test scores against major tests used in market. Test validity is analysed according to the Standards for Educational and Psychological Testing. It was notable that Duolingo’s Access Program waives its fees for eligible low-income and refugee candidates.
