The Duolingo English Test (DET) has marked another step in its global development with the release of Version 9. Now accepted by over 5,800 institutions worldwide — including Harvard, MIT, and Imperial College London — and taken by millions of students each year, the DET is fast becoming a mainstream option in international admissions.
The release of Version 9 signals a new chapter, introducing innovations that strengthen the test’s academic relevance, global comparability, and digital security. “These updates complete a vision we’ve been building toward for years,” said Brett Blacker, Duolingo’s Managing Director for Australia and New Zealand. “We’re seeing a clear maturation of the test.”
Fully Interactive Test Tasks
With Version 9, the DET will release a new item ‘interactive speaking’ from July 1. This completes Duolingo’s comprehensive suite of interactive items for reading, listening, speaking, and writing tasks. These new formats are designed to measure real-world academic and communicative skills more accurately. “These tasks give institutions deeper insight into a student’s ability to analyse, elaborate, communicate, and respond under pressure — just like in university settings,” Blacker said.
Now Recognised by Global Benchmarks
DET results are now independently benchmarked against the Canadian Language Benchmarks (CLB) and the Common European Framework of Reference for Languages (CEFR). These widely used frameworks support consistent, global interpretation of results, alongside previous alignment studies with IELTS and TOEFL. “This gives institutions greater confidence in evaluating applicants using DET scores,” Blacker noted.
Strengthened Security Measures
Duolingo has introduced new security features, including a secondary camera requirement, which uses a smartphone to provide a side view of the test environment. This step is designed to deter misconduct while supporting genuine test takers.
Additionally, mobile-first ID verification and updated AI detection tools have been introduced to identify fraudulent activity and minimise false rejections. “Security is about balancing integrity with fairness,” said Basim Baig, Duolingo’s Head of Security. “These updates improve both detection and the experience for honest users.”
A Fresh Look
The DET now features a new visual design aligned with the Duolingo learning app. While the test content and scoring remain unchanged, this refreshed look enhances brand familiarity and user confidence. Institutions using DET branding are encouraged to update logos and assets using Duolingo’s latest brand guidelines.
Upcoming Information Session
Duolingo will hold an industry webinar on Wednesday, 12 June at 10:00am AEST, to provide institutions with more information about the latest changes. The session will cover test updates, validation studies, and new research.
“Whether you’re considering DET for the first time or want to stay updated, the webinar will offer valuable insights,” Blacker said.
