The writing tasks in test order and their clocks

The Duolingo Writing Test assesses your ability to describe visual information, develop coherent ideas, and express and support your opinions. Different task types have different time limits, so effective time management is essential. Regular Duolingo writing practice can help you build these skills and become more comfortable responding under timed conditions. This LUME practice set includes three Write About the Photo exercises, a two-step Interactive Writing task, and a Writing Sample task.

Test sequence and timing breakdown

Task	Frequency	Preparation time	Response time
Write About the Photo	3 questions	No separate preparation period	1 minute per photo
Interactive Writing – Step 1	1 response	30 seconds (prompt shown first)	5 minutes
Interactive Writing – Step 2	1 response	Included in the response period	3 minutes
Writing Sample	1 response	30 seconds	5 minutes

The Writing Sample counts toward your Writing, Literacy and Production subscores, and institutions that receive your results can also read it. This allows institutions to evaluate your written communication. DET score reports include individual Writing and integrated subscores, such as Literacy and Production.

Operational clocks and pacing protocols

The following schedules are LUME’s suggested practice strategies, not official scoring rules or mandatory word counts. Adjust them to your writing speed and the demands of each prompt.

1. Write About the Photo – 60 seconds

• 0:00-0:15 – Observe and plan: Identify the main subject, visible actions, setting, and two or three relevant details.
• 0:15-0:45 – Draft: Write a connected description with accurate grammar and specific vocabulary. Aim for approximately 40-60 words as an initial practice target, not a minimum or official requirement.
• 0:45-1:00 – Review: Check subject–verb agreement, articles, prepositions, spelling, and punctuation.

Focus on describing what the image shows rather than inventing a detailed backstory. Clear, accurate sentences are more useful than unnecessarily complicated structures.

2. Interactive Writing Step 1 – 5 minutes

• Minute 1 – Interpretation and planning: Determine what the question is all about, state your position in case there is need for one and pick up two points to support your answer.
• Minutes 2-4 – Writing the answer: State your main point, give your reasons and cite an example. You could consider writing 100-130 words in the first trial.
• Minute 5 – Revising: Ensure your answer responds to the question and is written in a logical way with complete sentences.

3. Interactive Writing Step 2 – 3 minutes

• 0:00-0:30 – The follow-up: Understand the new question by determining what it asks you to consider, rethink or elaborate on.
• 0:30-2:30 – Expand on your thoughts: Compose a response that addresses the follow-up question. Setting a goal of 60-85 words can help you practice writing concisely.
• 2:30-3:00 – Review: Look at your sentence structure, grammatical correctness, and whether your expanded points say anything different from your original answer.

You don’t have to reproduce your original answer word for word. Rather, use it as the basis for expanding where appropriate to address the new question.

4. Writing Sample – 30 seconds of preparation and 5 minutes of writing

• First 30 seconds – Plan: Determine what position you will take and find one or two reasons or examples to support your position.
• Minutes 1-4 – Write: Craft a cohesive response with an introduction, explanation, and a conclusion if necessary. As practice, write around 130-170 words; however, ensure relevance and elaboration are more important than length.
• Last minute – Revise: Proofread for spelling, grammar, and punctuation; ensure that your response addresses the assigned topic.

Your Writing Sample will be sent to organizations reviewing your report, so be sure to make it a good representation of your writing skills. Official test instructions allocate 30 seconds to read the prompt before starting the five-minute writing period.

Three photos, one minute each

The Write About the Photo challenge evaluates your skills of converting visual data into grammatically advanced written language within a minute. Short or list-like answers show less of your English, so aim for connected sentences. Successful applicants do not rely on enumeration (“I see a tree and a dog”) but use participles, prepositional clauses, and deductive reasoning.

Here are three LUME practice items, not official DET questions. Each model answer is about 50 words and describes only what the photo shows. A slower typist may write less in 60 seconds, and that is fine.

Practice Item 1

A woman in a green cardigan is helping a young girl with her schoolwork at a table. The woman leans in and writes with a pen while the girl watches closely and smiles. A pile of books sits on the right, so they are probably doing homework or studying together.

Practice Item 2

A young couple is cooking together in a modern kitchen. The woman, in a black top, reaches over a bowl of fresh vegetables while the man beside her smiles and holds a small bowl. Orange salt and pepper shakers, a bowl of lemons and orange cookware cover the marble counter. They look relaxed and happy.

Practice Item 3

Two young women are exploring a city on a sunny day. The woman on the left wears a wide-brimmed hat and glasses, and she points into the distance while holding a map. Her friend, in a grey beanie and sunglasses, smiles as she takes a photo with a vintage-style camera. They look like happy tourists.

Interactive Writing: Step 1 and Step 2

Interactive Writing is used to evaluate how well you can develop ideas based on two related writing prompts. In Step 1, you will be asked to write for five minutes about a certain prompt. Then, in Step 2, another prompt will be provided, and you will have three minutes to continue writing about the topic from a different angle.

Effective det writing practice requires more than producing two separate paragraphs. In order to write good answers to the prompts, one is required to answer the prompts directly and provide their arguments by using appropriate reasoning. One can further add on to the initial answer by providing an argument in the follow-up.

Interactive Writing: Sequential flow

Stage	Time limit	Suggested practice target	Main objective
Step 1	5 minutes	100-130 words	Establish a position and develop supporting reasons
Step 2	3 minutes	60-85 words	Address the follow-up with relevant explanations or examples

The word counts above are LUME practice targets, not official DET requirements. Prioritize relevance, clarity, and effective English over reaching a particular word count.

Original Interactive Writing Scenario

Step 1 Prompt – 5 minutes

Many municipalities are considering replacing their public bus fleets with electric vehicles. Supporters argue that electric buses can reduce local air pollution, while critics point to high upfront costs and the challenges of providing sufficient charging infrastructure. Do you think municipal governments should prioritize the transition to electric public buses? Explain your position with supporting reasons.

Step 1 Model Answer

Municipal governments should prioritize the transition to electric buses because it can improve urban air quality and support long-term environmental goals. Conventional diesel buses release pollutants that contribute to poor air quality, particularly along busy roads where large numbers of people travel every day. Replacing them with electric vehicles can reduce tailpipe emissions and create healthier urban environments.

Although purchasing electric buses and installing charging stations require substantial initial investment, these costs should be evaluated alongside long-term operating expenses and potential environmental benefits. Governments could introduce electric buses gradually, beginning with routes where the transition is most practical, rather than replacing their entire fleets immediately. This approach would allow cities to assess costs, expand charging infrastructure, and adjust their plans as technology develops.

Step 1: Marked-up evaluation

• [Content – Direct response]: The opening sentence clearly states a position and identifies two supporting ideas: air quality and long-term environmental goals.
• [Discourse coherence – Logical development]: The response moves from environmental benefits to financial concerns before proposing a practical implementation strategy.
• [Lexis – Context-appropriate vocabulary]: Expressions such as “tailpipe emissions,” “charging infrastructure,” and “operating expenses” are specific to the topic and used naturally.
• [Grammar – Sentence control]: The response combines simple and complex sentences without relying on unnecessarily elaborate constructions.
• [Critical thinking – Qualified argument; LUME extra, not a DET criterion]: The suggestion to introduce electric buses gradually acknowledges financial constraints instead of assuming that every municipality can afford an immediate transition.

Step 2 Prompt – 3 minutes

Suppose your city decides to expand its electric bus fleet but cannot cover all the initial costs from its existing budget. Should the government increase bus fares or use general municipal tax revenue to fund the transition? Explain your choice and consider how it might affect residents.

Step 2 Model Answer

I would favor using general municipal tax revenue to fund most of the transition because cleaner public transport benefits the wider community, not just bus passengers. Raising fares could place additional pressure on low-income commuters and make public transport less affordable. However, relying on taxes also requires careful budgeting to avoid reducing funding for essential services. A gradual transition supported by public investment would therefore help cities improve air quality while keeping everyday travel accessible.

Step 2: Marked-up evaluation

• [Content – Addresses the new question]: The response clearly chooses tax revenue and explains the potential effects of higher fares.
• [Discourse coherence – Extends the argument]: It builds on Step 1’s recommendation for a gradual transition by discussing how that transition could be funded.
• [Lexis – Precise and natural wording]: “Low-income commuters,” “public investment,” and “essential services” communicate the relevant economic considerations clearly.
• [Grammar – Controlled complexity]: The infinitive of purpose “to avoid reducing funding” and the concluding clause express consequences without making the sentences unnecessarily complicated.
• [Critical thinking – Recognizes trade-offs; LUME extra, not a DET criterion]: The answer acknowledges that tax-funded projects still compete with other public spending priorities.

How to connect Step 1 and Step 2 effectively

Your follow-up needs to introduce a dimension to your initial answer. You don’t have to support all aspects of your previous answer if your new question requires a different view or qualification on some parts.

For instance, if you state in Step 1 that cities need to use electric buses, then Step 2 may be devoted to how to fund the shift in a fair way. In this case, you will show that you are capable of building an argument in response to a new question.

In practice, evaluate your two answers based on four aspects: content, discourse, grammar, and lexis. These aspects are helpful for evaluating LUME tasks but not a replacement of the DET marking system.

Original Writing Sample Prompt (30-Second Review + 5-Minute Timer)

Some educators argue that universities should replace traditional letter grades with written evaluations to reduce student stress and encourage intellectual exploration. Others believe that standardized grades are necessary for academic accountability and transparent postgraduate admissions. Discuss both viewpoints and explain whether you think qualitative evaluations should replace letter grading systems.

Writing Sample: Suggested pacing strategy

Time	Suggested activity
First 30 seconds	Identify both viewpoints and decide your position.
Minute 1	Introduce the issue and establish your main argument.
Minutes 2-3	Explain both perspectives using relevant reasons or examples.
Minute 4	Develop your own position and explain why you support it.
Final minute	Review grammar, spelling, punctuation, and logical flow.

Model Answer

The debate over qualitative evaluations and traditional letter grades centers on how universities should measure academic achievement. Supporters of written evaluations argue that detailed feedback can help students understand their strengths and weaknesses while encouraging them to explore challenging ideas without focusing exclusively on grades. In contrast, advocates of letter grading emphasize that standardized results make academic performance easier to communicate and compare, particularly when students apply to postgraduate programs or scholarships.

In my view, universities should combine both approaches rather than eliminate letter grades entirely. Written evaluations can provide personalized guidance that helps students improve throughout a course, while grades offer a concise summary of academic performance for official records. Although neither method captures every aspect of a student’s abilities, using them together would allow universities to maintain transparent assessment standards while giving students more meaningful feedback.

Marked-Up Evaluation Analysis

• [Content – Balanced development]: The first paragraph explains both viewpoints, while the second presents a clear position and explains why combining the two approaches may be beneficial.
• [Discourse coherence – Logical progression]: “In contrast” signals the opposing perspective, and “In my view” introduces the writer’s position. The conclusion follows naturally from the comparison.
• [Grammar – Controlled sentence variety]: The response uses subordinate clauses and contrastive structures accurately without making every sentence unnecessarily complex.
• [Lexis – Natural academic vocabulary]: Expressions such as “academic achievement,” “standardized results,” “personalized guidance,” and “transparent assessment standards” are appropriate to the topic.
• [Argument development – Qualified reasoning; LUME extra, not a DET criterion]: The answer acknowledges that neither assessment method is perfect and explains the practical value of combining them.

Writing Sample Structural Mapping

Paragraph	Main purpose	Key elements
Paragraph 1	Explain both viewpoints	Benefits of written feedback; value of standardized grades
Paragraph 2	Present and justify your position	Support a combined approach; explain the distinct role of each method; conclude with the overall benefit

Marked Answers: What Each Comment Means

The Duolingo English Test (DET) employs an automated grading system that is used for grading open-ended test items, including writing tasks. In the case of writing responses, the dimensions assessed by the published test include Content, Coherence, Grammar, and Lexis. These dimensions can be used to explain why writing entails more than grammar or vocabulary.

The Four Writing Assessment Criteria

Criterion	What It Evaluates	Practical Goal
Content	Relevance, style, development, and effect on the reader	Answer the prompt directly and support your ideas with relevant details.
Discourse Coherence	Clarity, cohesion, progression of ideas, and structure	Organize ideas logically and make relationships between them clear.
Grammar	Grammatical complexity, accuracy, and punctuation	Use a suitable range of sentence structures while maintaining accuracy.
Lexis	Vocabulary diversity, sophistication, word choice, word formation, and spelling	Choose precise, natural vocabulary that fits the topic and context.

1. Content

Content is an assessment of how well you respond to the question posed to you and the development of relevant ideas. You should not give general statements but rather give specific reasoning for any argument presented by you. For example, do not write “electric buses are good since they are clean,” but give reasons why.

2. Discourse Coherence

Discourse Coherence emphasizes the logical connection of your ideas. You should not use transition words where it is unnecessary. For instance, “Although the purchase of electric buses involves large upfront costs, reduced operational costs can compensate for part of the costs incurred” is an appropriate way of showing the logical relationship of the opposing views.

3. Grammar

Grammar involves correct grammar and sentence variety. Combine similar ideas where appropriate but do not sacrifice clarity for complexity. “The engineer looks at the drawings while wearing a hard hat” is a good combination of ideas without making a complex sentence.

4. Lexis

Lexical choice is about how to select the right word or phrase. Instead of imposing difficult or advanced words in your answer, use words which suit the context. For instance, the sentence “The potter creates earthenware on a revolving wheel” is much better than “The man is doing pottery activities.”

Improve English lexis by choosing precise, context-appropriate vocabulary to express ideas clearly and naturally in speaking and writing tests.

Where to Go Next Based on Your Weakest Criterion

To improve your duolingo writing practice, identify the area that most often affects your responses. Use the following questions to choose your next practice focus.

If You Struggle With…	Focus On…
Developing relevant ideas	Content: Plan a clear position and supporting reasons before writing.
Connecting ideas smoothly	Discourse Coherence: Practice logical paragraph structure and meaningful transitions.
Sentence accuracy	Grammar: Review sentence boundaries, clause structures, and punctuation.
Repetitive or unnatural vocabulary	Lexis: Learn topic-specific vocabulary and natural collocations.

Action Plan 1: Improve Grammar

Make sure you combine sentences effectively without forming run-on or comma-splice sentences. For instance, the two sentences “The worker put on a vest. The worker checked the plan” should be joined as “Wearing a safety vest, the worker checked the plan.” Check verb forms, verb agreement, and punctuation.

Action Plan 2: Improve Lexis

Increase vocabulary about commonly discussed subjects like education, technology, and the environment. Learn new words by context and give preference to collocations over synonyms which distort the meaning of the text. For example, “to reduce operating costs” is much more helpful than making the text complicated with unnecessarily difficult words.

Action Plan 3: Improve Discourse Coherence

Organize each response around the topic sentence and supporting details. Do not use “however,” “as a result,” “although” and similar transitional expressions unless they reflect the relation between the statements. Make sure that “this” and “these” point to specific concepts.

Action Plan 4: Improve Content

Before the writing process starts, find out what the question is, the main idea, and one or two supporting points. Explain or give examples without stating the same thing again. When practicing, ensure that you have addressed all parts of the question.
