The best online guide to the Duolingo English Test (DET) 2026. Question types, rules, scoring, and expert tips. Certify your English level with Duolingo!

If you are looking for an internationally recognised English exam that is fast, accessible, and can be taken from the comfort of your own home, the Duolingo English Test (DET) might be exactly what you need. In this complete guide, I am going to explain everything you need to know about this exam: from how it works to every type of question you will encounter, as well as the technical requirements, the rules you must follow, and the strategies to get the most out of your preparation.
The DET has gained massive popularity in recent years and is already accepted by more than 6,000 institutions worldwide, including Ivy League universities, elite business schools, and academic programmes in Europe, Asia, and Latin America. So, if you are thinking about studying abroad or need to certify your English level, this guide will be very useful for you.
The Duolingo English Test is a 100% online English proficiency exam that you can take from anywhere with an internet connection. Unlike other traditional exams such as IELTS or TOEFL, you don’t need to travel to an official centre or book a date weeks in advance. You simply buy the exam, take it whenever you want (within 21 days of purchase), and receive your certified results in approximately 48 hours.
The DET assesses the four main language skills: reading, listening, writing, and speaking. What makes it special is its adaptive format: the exam algorithm adjusts the difficulty of the questions as you answer, which allows it to accurately assess your level in less time than other exams.
Why are more and more students choosing the Duolingo English Test? Here are some of its main advantages:
The DET is primarily designed for international students who need to certify their English level to access university or postgraduate programmes. It is also useful if you need to demonstrate your linguistic proficiency for study visa applications in some countries, although it is advisable to check the specific requirements according to your destination.
It is especially popular among those looking for a more flexible and modern alternative to traditional exams, and among those who have tight deadlines and need quick results.
Before going into detail about the exam content, it is important that you know its basic features:
Once you complete the exam, you can send your results for free and without limits to all the institutions you wish, directly from your account on the Duolingo platform.
The DET has quite strict technical and environmental requirements, as they need to ensure the security and integrity of the exam when taken from home. Pay close attention to this section because failure to meet these requirements can result in your exam not being certified.

This is one of the most important requirements and the one that generates the most questions. Your mobile phone will act as a security camera during the exam:
During the initial phase of the exam, you will have to verify your identity by presenting a physical document to the camera. It is very important that you know which documents are acceptable in your country:
Very important: only original physical documents are accepted. Photocopies, digital images, or photographs of the document are not valid. It must be the real document.
The Duolingo English Test rules are strict, and failure to comply can have serious consequences, from your results not being certified to a permanent ban from taking the exam again. So, pay close attention to this section.
If you breach any of the Duolingo English Test rules, Duolingo reserves the right to:
The system uses artificial intelligence and human review to detect irregularities, so I strongly recommend that you follow all the rules to the letter.
The Duolingo English Test is divided into three main phases that total approximately 60 minutes. Let’s look at each of them in detail.
This initial phase is crucial to ensure that everything is in order before starting the assessed part of the exam. During these first minutes:
Once this phase is completed, you can no longer pause or stop the exam until it finishes.
This is the main part of the exam, where your English level is assessed. It lasts approximately 45 minutes and is completely adaptive.
The system uses an intelligent algorithm that adjusts the difficulty of the questions in real time based on your answers:
The interesting thing about the adaptive format is that two people taking the exam at the same time may see completely different questions, because the system personalises the experience according to each candidate’s performance.
Unlike other exams that have clearly separated sections (first reading, then listening, etc.), the DET integrates the four skills continuously. This means that:
During these 45 minutes, you will see all the types of questions that I will explain in detail in section 6 of this guide.
The final phase of the exam consists of two more extensive production tasks: a writing sample and a speaking sample. These tasks have special characteristics that you should know:
Writing Sample: you will be given a topic to write about for 5 minutes (with 30 seconds of prior preparation). They are usually questions about personal experiences or opinions.
Speaking Sample: you will answer a question orally for 3 minutes (also with 30 seconds of preparation). This response is recorded on video and universities can view it.
Since these samples go directly to universities, it is important that you take them very seriously and give your best. They are your opportunity to show not only your English level but also your communication ability, your personality, and your suitability as a candidate.
Understanding how the DET scoring system works will help you interpret your results and know what you need to achieve the level required by your target university.
The Duolingo English Test uses a scale from 10 to 160 points, with 5-point increments. This means the possible scores are: 10, 15, 20, 25… 150, 155, 160.
This scale is aligned with the Common European Framework of Reference for Languages (CEFR), which classifies language levels from A1 (beginner) to C2 (native or near-native mastery). Here is a general interpretation:
| DET Score | CEFR Level | Description |
|---|---|---|
| 10-55 | A1-A2 | Basic level: understanding of simple words and phrases |
| 60-95 | B1 | Intermediate level: everyday communication with some limitations |
| 100-125 | B2 | Upper intermediate level: capable of handling academic topics and complex situations |
| 130-160 | C1-C2 | Advanced level: fluent mastery in academic and professional contexts |
The scores are generated using artificial intelligence models specifically trained to evaluate language, combined with a security review process that includes both algorithms and human review before certifying the result.
In addition to your overall score, the DET provides eight subscores that give you a more detailed view of your performance. These are divided into two categories:
These measure each skill separately:
These combine pairs of skills to reflect integrated uses of the language:
All subscores use the same 10-160 scale in 5-point increments. It is normal to have different subscores; for example, you could have a Listening score of 120 but a Speaking score of 105. This helps you identify areas of strength and areas you need to improve.
Many students ask me how the DET compares to other well-known exams like IELTS or TOEFL. Here is an orientative equivalency table, although it’s important to remember that these are approximations and each institution sets its own thresholds:
| DET | IELTS | TOEFL iBT |
|---|---|---|
| 160 | 8.5-9 | 120 |
| 145 | 7.5 | 113-116 |
| 130 | 7 | 98-103 |
| 120 | 6.5 | 87-92 |
| 105 | 6 | 70-75 |
| 90 | 5 | 53-58 |
| 75 | 4.5 | 42-46 |
Important note: these equivalencies are approximate and orientative. Each university or institution sets its own minimum requirements for the DET according to its criteria. Always check the specific requirements of your target programme.
Now we come to the most practical part of this guide: knowing each type of question you will find in the DET in detail. The current exam (2026) includes 13 main types of tasks distributed among the four skills. I am going to explain each one with specific examples and strategies so you know exactly what to expect and how to tackle them.
Reading tasks in the DET are not limited to reading long passages and answering questions, as in other exams. They include vocabulary recognition tasks, completing words, and interactive reading. Let’s look at each type:
This task assesses your vocabulary recognition and spelling in English. You are presented with a list of mixed words: some are real English words and others are pseudo-words (invented words that look real but do not exist).

Time: 5 seconds per word | Frequency: 15-18 words per set | Adaptive: Yes
How it works: for each word that appears on the screen, you must click «Yes» if it is a real English word, or «No» if it is not.
Example of words:
Key strategies:
In this task, you must complete a sentence by typing the missing letters in an incomplete word. You are presented with a phrase with a partially hidden word, and you must complete it correctly.

Time: 20 seconds per sentence | Frequency: 6-9 sentences | Adaptive: Yes
How it works: a sentence appears with a word that has some visible letters and others hidden (represented by small boxes or gaps). You must type the missing letters to complete the word correctly.
Example:
«To prevent them from spoiling, perishable goods must be q u i __ __ __ __ transported from the production site to retail outlets.»
Answer: quickly (the missing letters are: c, k, l, y)
Key strategies:
This task is similar to Fill in the Blanks, but on a larger scale. You are presented with a full passage (a paragraph with a title) that contains multiple incomplete words, and you must complete them all.

Time: 3 minutes per passage | Frequency: 3-6 passages | Adaptive: Yes
How it works: a text appears with a title and several sentences. Some words are incomplete (with visible letters and gaps). You must click on each incomplete word and type the missing letters.
Important characteristics:
Key strategies:
This is one of the most complete and demanding tasks of the exam. You are presented with an academic or informative text and must respond to a series of 6 linked questions about it. The interesting thing is that the text is revealed progressively: each question shows you a little more of the passage.

Time: 7-8 minutes for the 6 questions | Frequency: 2 complete sets | Adaptive: Yes
How it works: you will see a text on an academic topic (it can be about science, history, technology, society, etc.) and you will answer 6 sub-questions in this specific order:
1. Complete the Sentences
The first half of the text appears with some gaps. You must select the correct word from a dropdown menu for each gap. There are between 4 and 6 gaps.

2. Complete the Passage
You are shown the first half of the text (already completed) and the beginning of the second half, but a transition sentence is missing between both parts. You must choose the best sentence from several options to connect both halves coherently.

3. Highlight the Answer – First time
You are asked a specific question about the text content and must click and drag to highlight (select) the exact part of the text that answers that question. You should not highlight too much or too little, only the relevant portion.

4. Highlight the Answer – Second time
Similar to the previous one but with a different question about another part of the text.
5. Identify the Idea
Now you have seen the full text. You are presented with several statements and must select which one best expresses the main or central idea of the entire passage.

6. Title the Passage
Finally, you must choose the most suitable title for the entire text from several options.

Key strategies:
DET listening tasks assess your ability to understand spoken English in different contexts. They include transcribing sentences and understanding conversations. Let’s look at each type:
This is a direct dictation task. You listen to a sentence in English and must transcribe exactly what you hear, word for word.

Time: 1 minute per sentence | Frequency: 6-9 sentences | Adaptive: Yes
How it works: an audio sentence is played and you can listen to it up to 3 times by clicking the play button. You must write exactly what you hear in the text box.
Example:
Audio: «My artistic journey began when I was young.»
You must write: My artistic journey began when I was young.
Key strategies:
This is another integrated and more complex task. You will listen to a scenario or conversation and perform three sequential activities related to that audio. It is one of the most realistic tasks in the exam because it simulates real communicative situations.

Time: 6:30 for Parts 1-2 + 75 seconds for Part 3 | Frequency: 2 complete sets | Adaptive: Yes
How it works: the task is divided into three consecutive parts based on the same audio scenario:
Part 1: Listen and Complete
You will listen to an introduction to the scenario (for example: «You are working on a research project with your professor…» or «You are talking to a colleague about an internship…»). This audio explains the situation and contains key information.

Afterwards, you will see several questions with blank spaces that you must complete by writing specific information you heard. For example:
Important characteristics:
Part 2: Listen and Respond
Now you will participate in a simulated conversation. A character (represented by audio and an avatar) will speak to you and you must select the best response from several options to maintain the conversation.

There are between 4 and 6 conversation exchanges. Each time the character speaks, you must choose your response from a menu of options. If you choose an incorrect response, the system shows you the correct one (and you can use that information for the following responses!).
Common themes include:
Part 3: Summarize the Conversation
Finally, you must write a brief summary of the conversation you just had in Part 2. You have 75 seconds to write it.

Your summary should include:
You can write in the first person («I talked with…») or in the third person («Two students discussed…»). The important thing is to use complete sentences, not bulleted lists.
Key strategies:
Writing tasks assess your ability to communicate in English in writing. They range from brief descriptions to longer structured responses. Let’s look at each type:
This is a quick written description task. You are shown a photograph and must describe what you see in it within a limited time.

Time: 1 minute per photo | Frequency: 3 photos | Adaptive: No
How it works: an image appears on the screen (it can be of people, places, objects, everyday scenes, landscapes, etc.) and you have exactly 1 minute to write a description of what you see.
Example of photo: An image of a street with a yellow tram, old buildings, and a person walking.
Example response: «The image shows a narrow cobblestone street in what appears to be a historic European city. A bright yellow tram is travelling down the tracks in the centre of the street. On both sides, there are tall, colourful buildings with traditional architecture. In the foreground, a single person is walking along the sidewalk. The sky is partly cloudy, suggesting it might be late afternoon.»
Key strategies:
This task simulates a real writing situation where you respond to a message or question, and then answer a related follow-up question. It is a two-part task that assesses your ability to develop ideas in writing coherently.

Time: 5 minutes (Part 1) + 3 minutes (Part 2) | Prep: 30 seconds | Frequency: 1 set | Adaptive: No
How it works: first you have 30 seconds to read the prompt and plan your response. Then you write two related but different texts:
Part 1 (5 minutes): You are presented with a situation or question and must respond in writing. For example: «Describe the last time you did something that challenged you. What did you do? What did you learn from the experience?»
Part 2 (3 minutes): After completing Part 1, a related follow-up question appears asking for different information. For example: «Discuss how this challenging experience required you to develop or use problem-solving skills. Describe the strategies you used and how they helped you approach this task.»
It is important to note that Part 2 asks something different from Part 1, so you cannot simply repeat what you already wrote.
Key strategies:
This is your writing sample that will be sent directly to universities along with your score. It is your chance to demonstrate your ability to write in a structured, coherent, and persuasive way on a given topic.

Time: 5 minutes | Prep: 30 seconds | Frequency: 1 | Adaptive: No
How it works: you are presented with a topic or question asking for your personal experience or opinion. You have 30 seconds to read and think, and then 5 minutes to write your response.
Example prompt: «Due to the invention of cell phones, people can communicate via text messages. Describe the ways texting has changed how we communicate.»
Special characteristics:
Key strategies:
Speaking tasks assess your ability to communicate verbally in English. They include descriptions, responses to questions, and simulated conversations. All are recorded, so ensure your microphone works well. Let’s look at each type:
Similar to Write About the Photo, but oral. You are shown a photograph and must verbally describe what you see during the available time.

Time: 90 seconds to speak | Prep: 20 seconds | Frequency: 1 photo | Adaptive: No
How it works: an image appears on the screen. You have 20 seconds to observe it and think about what you are going to say. Then you click «Record Now» and have 90 seconds to speak describing the image.
Photo characteristics: they are real images of people, animals, or everyday scenes (not IA-generated images). They can show diverse situations: landscapes, activities, public places, domestic scenes, etc.
Key strategies:
In this task, you read a written prompt that asks you a question about personal experiences or opinions, and then you respond orally.

Time: 90 seconds to speak | Prep: 20 seconds | Frequency: 1 | Adaptive: No
How it works: a written prompt is presented on the screen (for example: «Describe a time you worked with other people on something. What did you collaborate on? Who did you collaborate with? Do you enjoy collaborating with others? Why or why not?»). You have 20 seconds to read and think, and then 90 seconds to speak.
Often the prompt includes several guiding questions or bullet points indicating which aspects you should cover in your response.
Key strategies:
This task simulates a real conversation. A Duolingo character (represented by an avatar and audio) will ask you questions about two different topics (3 questions per topic), and you must respond orally to each one.

Time: 35 seconds per question | Frequency: 6 questions in total (2 topics × 3 questions) | Adaptive: Yes
How it works: the character asks you a question in audio (for example, about your hobbies, your daily routine, your future plans, etc.). You listen to the question and then have 35 seconds to respond orally. Then they ask you another related question, and so on.
The questions adapt according to your performance: if you respond well, the following ones may be more complex or profound.
Important characteristics:
Key strategies:
This is your speaking sample which will be sent directly to universities in video format along with your score. It is your chance to demonstrate your speaking ability more extensively and show some of your personality.

Time: 3 minutes to speak | Prep: 30 seconds | Frequency: 1 | Adaptive: No
How it works: you listen to a question on a topic of personal experience or opinion (similar to Read, Then Speak but with more time). You have 30 seconds to think and then 3 full minutes to respond. This response is recorded on video.
Example prompt: «Imagine that your supervisor has offered you a choice between two positions. One consists of tasks that you do really well, while the other would be more challenging and involve learning new skills. Which do you prefer? Why? Give specific reasons for your answer.»
Special characteristics:
Key strategies:
Understanding how your answers are evaluated will help you better focus your preparation and performance in the exam. The DET uses artificial intelligence models specifically trained to evaluate language according to clear linguistic criteria. Let’s see what aspects are valued in writing and speaking tasks.
Writing tasks are evaluated according to four main criteria:
| Criterion | What is evaluated |
|---|---|
| Content |
Relevance: Does your text answer the question posed? Completeness: Do you address all the requested aspects? Appropriate style: Is the tone and register suitable? Idea development: Do you elaborate on your points with examples and details? |
| Discourse Coherence |
Clarity: Is what you write easily understood? Cohesion: Do you use appropriate connectors between ideas? Logical progression: Do ideas flow in an orderly fashion? Structure: Is there an introduction/conclusion and well-organised paragraphs? |
| Grammar |
Variety of structures: Do you use different sentence types (simple, compound, complex)? Grammatical accuracy: Are verb tenses, agreements, etc., correct? Punctuation: Do you correctly use full stops, commas, and capital letters? |
| Lexis |
Vocabulary diversity: Do you avoid constantly repeating the same words? Sophistication: Do you use vocabulary appropriate for the academic level? Precision: Do you choose the right words to express your ideas? Spelling: Do you write the words correctly? |
To obtain a high score in writing, you need to demonstrate competence in all these criteria. It is not enough to have good grammar if your text does not answer the question, nor to have relevant ideas if the expression is confusing or contains many errors.
Speaking tasks are evaluated according to six main criteria (there are more than in writing because specific aspects of oral communication such as fluency and pronunciation are added):
| Criterion | What is evaluated |
|---|---|
| Content |
Relevance: Does your speech answer the question? Completeness: Do you address the requested points? Appropriate style: Is the tone suitable? Development: Do you elaborate on your ideas with details? |
| Discourse Coherence |
Clarity: Is what you say easily understood? Cohesion: Do you use appropriate connectors? Logical progression: Do ideas flow in an orderly manner? |
| Fluency |
Appropriate speed: Do you speak at a natural pace (neither too fast nor too slow)? Natural pauses: Are pauses logical or do they interrupt communication? Few fillers/repetitions: Do you avoid excessive filler words («um», «uh», «like»)? |
| Grammar |
Variety of structures: Do you use different grammatical constructions? Grammatical accuracy: Are verb tenses, agreements, etc., correct? |
| Lexis |
Vocabulary diversity: Do you avoid repeating the same words? Sophistication: Do you use vocabulary appropriate for the academic level? Appropriate choice: Do you choose the right words for the context? |
| Pronunciation |
Intelligibility: Are you clearly understood? Individual sounds: Do you correctly pronounce English phonemes? Word stress: Do you stress the correct syllable in words? Intonation: Do you use appropriate intonation patterns for sentences/questions? |
It is important to highlight that you do not need to have a native accent to get a good score in pronunciation. What is valued is intelligibility: that you are understood clearly even if you have a Spanish, Latin American, or any other regional accent. The crucial thing is that pronunciation does not interfere with communication.
One of the most frequent questions I receive is: «Do they really accept the DET in good universities?» The answer is a resounding yes. The Duolingo English Test has experienced spectacular growth in international recognition in recent years.
According to updated data from Duolingo:
Acceptance in the USA is particularly impressive:
Canada has been one of the countries with the highest adoption of the DET:
Recognition in English-speaking countries in Europe is also solid:
Major universities in Oceania also accept the DET:
Outside the traditional English-speaking world, numerous universities use the DET to assess the English proficiency of international students:
In the migration field, the situation is more variable:
Recommendation: always check the specific requirements of your target programme and the type of visa you will need. The best way to do this is:
To prepare properly for the DET and ensure you have the most up-to-date information, it is fundamental that you consult official Duolingo resources. Here is a complete guide to finding everything you need:
In addition to free official resources, there are specialised platforms that offer more complete and structured preparation. For example, DETPractice.com is an official Duolingo English Test Gold Partner and offers:
Other similar platforms also offer preparation materials, online courses, and specialised DET tutoring.
Exam day can cause nerves, but with good technical and mental preparation, everything will go smoothly. Here are my best tips as an examiner and tutor:
Before purchasing or starting the exam, verify:
Support contact: you can contact the DET support team through their help centre at englishtest.duolingo.com if any problem arises before, during, or after the exam.
Throughout my years preparing students for the DET, these are the questions I am asked most frequently:
You can purchase up to 3 exam attempts in any 30-day period. If you buy a bundle of 2 exams, you have 21 days to take the first one, and then an additional 21 days after receiving the result of the first one to take the second.
The international standard price is 70 USD (dollars) and it is available on the official page at the time of purchase and is usually considerably more affordable than IELTS or TOEFL. Duolingo occasionally updates prices, so check the official website for the most current information.
No. It is strictly forbidden to use earphones, headphones, or any audio device. Your ears must be visible at all times for both cameras. You can use your computer’s built-in speakers or external speakers.
No. You cannot use paper, pen, or any material to take notes during the exam. Everything must be done mentally or directly on the computer when the task requires it (for example, when writing).
The DET application will attempt to reconnect automatically if there is a brief interruption. If the disconnection is prolonged and you cannot complete the exam, you must contact Duolingo support immediately (with evidence of the problem if possible) so they can evaluate your case and potentially offer you a new attempt.
Once you receive your certified results (approximately 48 hours after the exam), you can send them for free and without limits to as many institutions as you wish directly from your account on the DET platform. You simply search for the institution, select the specific programme (if applicable), and send your certificate digitally.
More and more universities in Spain and Latin America that offer English-taught programmes or assess language proficiency accept the DET. To find out if your target university accepts it, use the official institution search tool at englishtest.duolingo.com/institutions or contact the admissions office of the programme you are interested in directly.
DET results are valid for 2 years from the date you took the exam. However, some institutions may have their own policies regarding the acceptable age of results, so always check with your target programme.
For security reasons and to protect the integrity of the exam, you cannot see your specific answers or the questions you were asked after completing the test. What you will receive is your overall score and subscores, which give you an overview of your performance.
There is no minimum level required to take the DET. The exam is adaptive and can assess from beginner level (A1) to advanced (C2). However, if your goal is university admission, verify what minimum score your target programme requires (most ask for between 100-120 or higher, equivalent to B2-C1).
The Duolingo English Test represents a significant evolution in language proficiency certification. Its modern, adaptive, and flexible format has made it an increasingly popular alternative to traditional exams like IELTS or TOEFL, without sacrificing academic rigour or international recognition.
Throughout this guide, you have learned everything essential about the DET:
If you are considering taking the DET, these are the steps I recommend you follow:
Remember that the DET, like any language exam, is a tool to demonstrate communicative competence, not an end in itself. What matters is your real ability to use English in academic and professional contexts. The exam simply certifies that skill.
So, while you prepare, focus not only on «passing the exam» but on genuinely improving your English: read articles in English, listen to podcasts, practise writing about varied topics, and speak with natives or fellow students. This real improvement will naturally translate into a better score in the DET, and most importantly, it will prepare you to succeed in your international studies.
The path to your academic goal may seem challenging, but with the right preparation and mindset, the Duolingo English Test is an excellent option to certify your English level quickly, flexibly, and with international recognition.
I hope this complete guide has been useful to you and has given you all the information and confidence you need to face the DET successfully.
