Wono DET Joins the Duolingo English Test Global Partner Network
Wono DET is now part of the Duolingo English Test Global Partner Network. Here is what that means, what changes in your practice scores and feedback, and how to register for the official test through our partner link.
The Short Version
Wono DET is now part of the Duolingo English Test (DET) Global Partner Network. The network brings together study-abroad agents, test preparation companies and education organizations that help students take the DET.
For you, this means three things:
- Practice scores follow the DET's 2026 scoring guidance more closely
- Feedback is cleaner, with grammar corrections that only point out real mistakes
- You can register for the official test through our partner link when you are ready
Wono DET is still an independent practice tool. Read on for the details.
What the Global Partner Network Is
The Global Partner Network (GPN) is the Duolingo English Test's program for organizations that prepare students for the test or refer them to it. Partners get access to test readiness materials, training on how the test works, and a partner invite link that students can use to register.
Joining gives us direct access to the DET's own materials for teachers and test prep providers, including its scoring guide. We used that guide to review how Wono DET evaluates your answers.
What It Does Not Mean
We want to be precise about this:
| Question | Answer |
|---|---|
| Is Wono DET an official Duolingo product? | No. Wono DET is independent and is not endorsed by Duolingo |
| Are Wono DET scores official DET results? | No. They are practice estimates. Only the real test gives you an official score |
| Do I need Wono DET to take the DET? | No. You can register directly on the official DET website |
| Does Wono DET guarantee a score? | No. No practice tool can guarantee a test result |
What Changes in Your Practice
1. Scoring aligned with the 2026 scoring guide
We reviewed our AI evaluator against the DET's scoring guidance for teachers and adjusted it:
- Six score bands, from 10-25 up to 155-160, with descriptions for each criterion at every level
- The same criteria the DET uses for writing: content, coherence (organization), grammar and vocabulary. Speaking adds fluency
- Punctuation counts under grammar and spelling counts under vocabulary for writing, and both UK and US spelling are accepted
- Short, accurate answers are no longer under-scored. A clear 60-second description that covers the main parts of the photo can now land in the 130s, as it can on the real test
- The top band is reachable. A complete, precise and error-free answer can now score 150-160 instead of stalling in the 140s
- Reasonable inferences are rewarded. Saying what people in the photo might be doing or feeling, when the photo supports it, now counts as a strength
Pronunciation is part of the official speaking score, but Wono DET evaluates a transcript of your recording, so it does not score pronunciation.
2. Scores are shown as a range
An AI evaluation can move by about one step between attempts on the same answer, so a single exact number promised more precision than any practice tool can offer. Each practice result now shows an estimated range, for example 130–140, instead of one number.
Your averages, charts and progress tracking still use single numbers, so you can still see small improvements over time.
3. Grammar corrections only show real mistakes
Before, a strong answer could still receive "corrections" that were really style preferences. Now the grammar review only lists genuine errors, such as subject-verb agreement, articles, tense, prepositions, punctuation and spelling. Style suggestions appear separately as optional polish.
If your answer has no real errors, the correction list will be empty. That is a good sign, not a bug.
Registering for the Official Test Through Our Partner Link

A few honest notes:
- You take the test on the official DET website. Registration, payment, identity checks and results are all handled by Duolingo
- Tests bought through this link count as a referral for Wono DET in the partner program. That helps us grow within the network and support more learners
- It does not add any fee from us. You can also register directly on the DET website if you prefer

Frequently Asked Questions
Will my old practice scores change?
No. Past attempts keep the scores they received. New attempts are evaluated with the updated rubric, so you may notice your scores sitting a little higher for answers of the same quality.
Is my practice score the score I will get on the real test?
Not exactly. Wono DET estimates your level on the two photo tasks, while the real DET combines many task types into your final score. Use the range as a guide to your level and your trend, not as a prediction of one exact number.
Can I still use Wono DET if I register for the DET somewhere else?
Yes. Practice works the same way no matter where or how you register.
What's Next
Being part of the network gives us ongoing access to training and test updates from the DET team. As the test changes, we will keep Wono DET's practice and scoring in line with it.
