Short Answer
Sometimes. The DET fee is generally non-refundable, but Duolingo does issue refunds in specific circumstances — mainly technical problems on their end or unreasonably delayed results. A refund isn't available if your test was invalidated because you broke a testing rule.
When You're Likely to Get a Refund
- A technical failure prevented you from completing or submitting the test
- Your results were delayed well beyond the normal processing window with no clear explanation
- A verified issue with Duolingo's own systems disrupted your session
When You Won't Get a Refund
- You broke a testing rule (background software, someone entering the room, gaze violations, etc.) and your test was invalidated
- You simply changed your mind or ran out of time within your 21-day window
- You were unhappy with your score
How to Request One
Contact Duolingo's test support as soon as possible — ideally within 24 hours of the issue occurring. The longer you wait to report a technical problem, the harder it is to make the case that the issue was on Duolingo's end rather than your own setup.
