The Duolingo English Test (DET) uses a score range of 10 to 160, where higher scores reflect stronger English proficiency. Each score corresponds to a CEFR level, making it easy for universities and institutions worldwide to interpret your result.
| Score | CEFR Level | Description |
|---|---|---|
| 160 | C2 | Mastery — Highly fluent, precise use of English in all contexts |
| 130–155 | C1 | Advanced — Effective and flexible use of English for professional and academic purposes |
| 115–125 | B2 | Upper-Intermediate — Independent communication on a wide range of topics |
| 95–110 | B1 | Intermediate — Can handle most everyday situations and familiar topics |
| 65–90 | A2 | Elementary — Basic communication in simple, familiar situations |
| 10–60 | A1 / Below | Beginner — Very limited communication, only isolated words or phrases |
The Duolingo English Test uses an adaptive algorithm — questions get harder or easier based on your performance in real time. This means there is no fixed set of questions; the test adjusts throughout to measure your precise level.
| Subscore | What It Measures |
|---|---|
| Literacy | Reading and writing skills — includes sentence completion and error identification tasks |
| Comprehension | Listening and reading together — assesses overall understanding of written and spoken input |
| Conversation | Speaking and listening — tests real-time verbal interaction and listening comprehension |
| Production | Speaking and writing combined — evaluates how well you generate language independently |
Your overall Duolingo score is a single number between 10 and 160. It is generated by the test’s AI model and reflects your performance across all question types during the adaptive test.
Unlike IELTS, there is no manual averaging of section scores. The AI model weighs all your responses — reading, writing, listening, and speaking tasks — together to produce a holistic score. Scores are reported in increments of 5.
Here is how scores across tasks typically translate into overall results:
A candidate with strong reading and writing but weaker speaking may score in the 105–120 range (B1–B2 level).
A candidate who struggles with listening and production is likely to score between 75 and 95 (A2–B1 level).
Duolingo English Test scores are valid for 2 years from the date you took the test. After this period, your score certificate can no longer be used for university applications, visa applications, or any other official purpose.
If your score expires before you use it, you will need to retake the test. There is no fee waiver or exception for expired scores, even if they were never submitted to an institution.
After completing the Duolingo English Test, your result goes through a two-step review process before being officially released. The timeline is generally fast — most candidates receive results within 2 days.
| Milestone | Timeframe | Details |
|---|---|---|
| AI Certification Check | Immediately after test | AI verifies test validity before sending for review |
| Human Proctor Review | Within 2 days | A certified proctor manually reviews your test session |
| Score Delivery (Standard) | 2 days after test | Most results are available within 48 hours |
| Score Delivery (Extended) | Up to 5 business days | Rare cases requiring additional review may take longer |
| Score Validity Expires | 2 years from test date | Scores older than 2 years are no longer accepted |
Once your score is ready, you will receive an email notification from Duolingo. All results are available exclusively through your Duolingo English Test account — there is no paper score report.
If you believe your result does not accurately reflect your ability, Duolingo’s process is different from traditional tests. Since scoring is fully automated by AI, there is no human remarking service like an IELTS EOR.
The maximum score on the Duolingo English Test is 160. This represents the highest level of English proficiency (C2 on the CEFR scale) and indicates mastery of the language in all contexts.
Most candidates receive their Duolingo results within 2 days of completing the test. In rare cases where additional review is required, results may take up to 5 business days. You will be notified by email when your score is ready.
Duolingo English Test scores are valid for 2 years from the date of the test. After 2 years, the score certificate can no longer be submitted to universities, immigration authorities, or other institutions for official purposes.
