Duolingo English Test Subscores Explained: How Your Score Is Calculated
Duolingo English Test subscores explained: how Reading, Listening, Writing and Speaking form your overall score, what combined scores mean, and how to improve.
Why Your Subscores Matter More Than You Think
When your Duolingo English Test (DET) results arrive, most people look at one number: the overall score. But that number is built from smaller scores, and those smaller scores tell you exactly where you are losing points.
If you only track the overall number, you can miss the one skill that is quietly holding you back. It is also worth checking whether your target university or scholarship lists any requirements for individual skills, not just the overall score.
This guide explains how DET scoring works, based on the official DET Scoring Guide for Teachers (2026) published by Duolingo, and shows how to turn your subscore profile into a practice plan.
The Short Version
| Item | How it works |
|---|---|
| Score scale | 10 to 160, in steps of 5 |
| Main subscores | Reading, Listening, Writing, Speaking |
| Overall score | Average of the four main subscores, rounded up to the nearest 5 |
| Combined subscores | Literacy, Comprehension, Conversation, Production |
| Combined subscore value | Average of the two main subscores it includes |
| Task weights | Published for Writing and Speaking (see below). Not published for Reading and Listening, where many questions are adaptive, so the score is not a simple count of correct answers |
How the Overall Score Is Calculated
According to the official scoring guide, you receive four main subscores: Listening, Speaking, Reading, and Writing. Each one is on the same 10-160 scale as the overall score.
The overall score is simply the average of those four subscores, rounded up to the nearest 5. The guide gives this example:
| Subscore | Score |
|---|---|
| Listening | 90 |
| Speaking | 100 |
| Reading | 110 |
| Writing | 120 |
| Overall | (90 + 100 + 110 + 120) ÷ 4 = 105 |
This has a very practical consequence: every skill carries equal weight in the overall score. Raising your weakest subscore by 20 points moves the overall score exactly as much as raising your strongest one by 20 points, and the weak one usually has more room to grow.
The Four Combined Subscores
Your results also show four combined (integrated) subscores. Each is the average of two main subscores:
| Combined subscore | Built from | What it reflects |
|---|---|---|
| Literacy | Reading + Writing | Working with written English |
| Comprehension | Reading + Listening | Understanding English input |
| Conversation | Speaking + Listening | Real-time spoken interaction |
| Production | Speaking + Writing | Producing your own English |
For example, Reading 110 and Writing 120 give a Literacy subscore of (110 + 120) ÷ 2 = 115.
Combined subscores do not add new information about your ability. They regroup the four main skills so institutions can see, for example, whether you are stronger at understanding English or at producing it. For your own study plan, start from the four main subscores, then use the combined ones to spot patterns. A low Production score, for instance, means both your speaking and writing need work.
Which Questions Feed Which Subscore
This is the part most test takers never look at. The official guide maps every question type to a subscore:
| Question type | Per test | Time | Main subscore |
|---|---|---|---|
| Read and Select | 15-18 | 5 sec each | Reading |
| Fill in the Blanks | 6-9 | 20 sec each | Reading |
| Read and Complete | 3-6 | 3 min each | Reading |
| Interactive Reading | 2-3 passages | 7-8 min each | Reading |
| Listen and Type | 6-9 | 1 min each | Listening |
| Interactive Listening (Listen and Complete, Listen and Respond) | 2-3 scenarios | 6:30 combined | Listening |
| Summarize the Conversation | 2 | 1:15 | Writing (content also counts toward Listening) |
| Write About the Photo | 3 | 1:00 | Writing |
| Interactive Writing | 1 (two parts) | 5 min + 3 min | Writing |
| Writing Sample | 1 | 5:00 | Writing |
| Speak About the Photo | 1 | 20 sec prep, up to 90 sec | Speaking |
| Read Then Speak | 1 | 20 sec prep, up to 90 sec | Speaking |
| Interactive Speaking | 6-8 questions | up to 35 sec each | Speaking |
| Speaking Sample | 1 | up to 3 min | Speaking |
Two takeaways:
- Writing and Speaking are fed by many separate tasks. Write About the Photo alone appears three times in every test, so it is one of the most repeated writing tasks you will face.
- The Writing Sample and Speaking Sample are shared with institutions. Schools you send results to can read your Writing Sample and watch a video of your Speaking Sample, in addition to seeing your scores.
How Much Each Task Counts Toward Writing and Speaking
For Writing and Speaking, the official guide publishes how much each question type contributes to the subscore (all questions of that type combined):
| Speaking task | Share of Speaking score |
|---|---|
| Speak About the Photo | 20% |
| Read Then Speak | 20% |
| Speaking Sample | 20% |
| Interactive Speaking | 40% |
| Writing task | Share of Writing score |
|---|---|
| Interactive Writing, Step 1 | 11% |
| Interactive Writing, Step 2 | 11% |
| Write About the Photo (×3) | 33% |
| Summarize the Conversation (×2) | 22% |
| Writing Sample | 22% |
The guide notes that these percentages are rounded and describe each task's share of the Writing or Speaking subscore, not of the overall score. Even so, they are useful for planning: Write About the Photo is the single largest block of your Writing subscore, and Speak About the Photo carries the same weight as Read Then Speak or the Speaking Sample, while Interactive Speaking is the biggest part of Speaking.
How Writing and Speaking Are Graded
Reading and listening questions are scored as right/wrong or with partial credit. Writing and speaking tasks are scored by AI against fixed criteria:
| Criterion | Writing | Speaking | What it checks |
|---|---|---|---|
| Content | ✅ | ✅ | Do you answer the task fully, with relevant detail? |
| Discourse coherence | ✅ | ✅ | Is the answer organized and connected? |
| Grammar | ✅ | ✅ | Range and accuracy of structures (punctuation for writing) |
| Lexis | ✅ | ✅ | Range and precision of vocabulary (spelling for writing) |
| Fluency | ✅ | Speed, natural pauses, few breakdowns | |
| Pronunciation | ✅ | Clear sounds, stress, and intonation |
The guide also notes two details worth knowing: any standard English accent is accepted if it is easy to understand, and both UK and US spellings are accepted in writing. The AI also looks for answers that are off topic, contain little meaningful language, or rely heavily on repetition, and gives those very low scores. Memorized, generic templates are risky for exactly this reason.
What separates the score bands on photo tasks
The guide describes what a photo description looks like at each level. Simplified:
| Score band | Typical photo description |
|---|---|
| 155-160 | Fully describes the image: key people, objects, and actions, plus logical inferences |
| 130-150 | Main parts with appropriate detail, some inferences, mostly focused on what is visible |
| 100-125 | Mentions the main parts and some details, but may miss one or two key features |
| 60-95 | Some parts of the image, short, general, or repetitive |
| 30-55 | One or two things named without real description |
The jump from the 100s to the 130s is usually not about fancy vocabulary. It is about covering all the key features and adding a reasonable inference about what is happening.
What Your Subscore Profile Is Telling You
Once you have your results (or a practice result), compare the four main subscores. Here is how to read the most common patterns:
| Pattern | Likely cause | Where to focus |
|---|---|---|
| Reading and Listening high, Writing and Speaking low (low Production) | You understand English well but rarely produce it under time pressure | Timed writing and speaking practice with feedback |
| Writing high, Speaking low | Freezing, long silences, or short answers when recording | Speak About the Photo and Read Then Speak drills, aim to use most of the time |
| Speaking high, Writing low | Grammar slips, spelling, or very short typed answers | Write About the Photo under a 1-minute timer, proofread habits |
| Listening lowest | Trouble with Listen and Type spelling or following conversations | Dictation practice, academic conversations, summarizing what you hear |
| Reading lowest | Limited vocabulary recognition, slow reading | Word recognition, reading academic texts, completing partial words |
Because the overall score is a simple average, lifting the lowest subscore is almost always the fastest route to a higher overall score.
A 4-Week Plan Built Around Subscores
| Week | Goal | What to do |
|---|---|---|
| 1 | Find your baseline | Use the subscores from a previous certified test if you have one; otherwise take the official practice test on the DET website for an estimated score range and note which sections felt hardest |
| 2 | Attack the weakest skill | Spend about 60% of study time on your lowest subscore, 40% on the rest |
| 3 | Fix Production habits | Daily timed photo tasks: 3 written (1 minute each) and 1 spoken (up to 90 seconds), reviewing feedback after each |
| 4 | Simulate and stabilize | Full timed practice runs, keep answers on topic, rest the day before the test |
Checklist for the photo tasks
- Start with an overview sentence: who or what, and where
- Cover every key person or object, not just the first one you notice
- Describe at least one action with the present continuous
- Add one reasonable inference ("They might be celebrating...")
- Use linking words to connect ideas instead of listing them
- Speaking: avoid long silences and keep talking until near the end of the time
- Writing: leave a few seconds to fix obvious spelling and punctuation
Practicing the Photo Tasks With Feedback
Writing and Speaking are the hardest skills to judge on your own, because you cannot easily see your own grammar slips or hear your own pauses. Wono DET is an independent practice tool (not affiliated with Duolingo) focused on Write About the Photo and Speak About the Photo. After each timed answer you get an estimated score, scores for content, organization, vocabulary, and grammar (plus fluency for speaking), grammar corrections, and a stronger sample answer. New accounts get 5 free corrections, enough to see which criterion is pulling your Production score down.

Conclusion
Your DET overall score is just the average of four skills. Once you know that:
- Read all four main subscores, not just the overall number
- Use the combined subscores to spot patterns such as weak Production
- Put most of your effort into the lowest subscore
- Practice Writing and Speaking under real time limits with feedback on the official criteria
Start with your baseline today. If Writing or Speaking is your weakest skill, try a few timed photo answers on Wono DET and note which criterion keeps scoring lowest. That is your focus for the next week.
