DET Writing Score Tips: Clear Answers, Timing and Practice

DET writing tips for photo descriptions, Interactive Writing and the five-minute Writing Sample. Learn what official guidance says and practise clear answers.

Why writing scores stay lower than they should

Good writing answers the prompt, develops ideas and remains easy to follow. A short answer may not show much of your ability, but length alone does not guarantee a higher score.

Practise under the task timer. Leave time to check spelling, grammar and punctuation. Official Writing Sample guidance

Write for the question

Relevant ideas, clear organisation, suitable vocabulary and accurate grammar matter. Do not rely on an unpublished algorithm trick.

What official writing guidance recommends

Official guidance emphasises relevant ideas, logical organisation, grammar and suitable vocabulary. It does not publish a fixed penalty for repeating one word or a guaranteed score increase for a particular phrase.

  • Answer every part of the prompt.
  • Develop your point with a reason or example.
  • Use sentence structures and vocabulary you can control.
  • Check spelling and punctuation.

DET writing guidance

A short review checklist

Did I answer the question, develop my ideas and check the language?

Practice one skill at a time

Review one recurring issue after each timed response.

Write about the photo: the 60-second formula

You have one minute to describe a photo. Start with the main subject or action, then add visible details.

“There is” is acceptable English. Vary your sentences when it helps, rather than avoiding a phrase because of an imagined scoring penalty.

A practical plan is: main action, setting or detail, then another relevant observation. If you make a guess, label it with “might” or “appears to.”

The example below is original practice material, not an official scored answer. There is no verified minimum of three sentences or 30 words.

Weak

“There is a woman working on a laptop. There is a window. She looks busy.”

Strong

“A focused professional types intently on her laptop in a sunlit modern office. Large windows reveal a city skyline in the distance. Based on her formal attire and the stack of papers beside her, she appears to be preparing for an important presentation.”

Start clearly

Name the main subject or action. “There is” is allowed; choose the opening that best describes the photo.

Your 60-second plan

First 10 seconds: study the photo. Next 45 seconds: write sentence 1 (action), sentence 2 (details), sentence 3 (guess). Last 5 seconds: spot-check for typos. Practice this rhythm on five random photos and it becomes automatic.

Interactive writing: the two-part task most people get wrong

Interactive Writing has two connected responses: five minutes for the first prompt and three minutes for a follow-up based on your answer. DET writing guidance

Answer Part 1 fully. Do not deliberately leave out information the prompt asks for. Read the follow-up and respond to that question; add a reason, example or explanation where useful.

For practice, use a clear position, a supporting reason and an example. This is a writing plan, not a score formula or required word count.

Answer both prompts

Give a complete first answer, then respond directly to the follow-up.

Add detail where needed

A follow-up may ask for more explanation. Read it before choosing your next point.

The Writing Sample: a five-minute response

The Writing Sample gives you 30 seconds to read the directions, followed by five minutes to write. Official Writing Sample guidance

  • Answer the question directly.
  • Develop your answer with reasons and examples.
  • Put related ideas together and connect them clearly.
  • Leave time to check grammar, spelling and punctuation.

Duolingo does not publish a rule that 50 words caps your score or that 100–150 words earns a particular result. Use enough relevant detail to explain your answer. You may continue when finished; use remaining time to review rather than add filler.

5 minutesWriting Sample response time

No published 50-word score cap

Develop your answer with relevant detail. Extra words alone do not guarantee a higher score.

Choose accurate words and useful connections

Choose words that convey your meaning accurately. A rare word used badly is less useful than a familiar word used well.

Contractions: “do not” may suit formal writing, but removing every contraction does not guarantee a score increase.

Repetition: vary wording where natural. Keep a repeated technical or topic word if replacing it would change your meaning.

Connections: use “however,” “for example” or “as a result” only when the relationship fits. No transition word guarantees extra points.

Official Writing Sample guidance

Unclear link

Adding “Furthermore” when the next sentence contradicts the previous one

Clear link

Using “However” to introduce a contrast

Match the tone

Use wording appropriate to the task. Contraction removal is not an automatic score boost.

Keep the meaning clear

Vary wording when useful. Do not replace accurate words with unsuitable synonyms.

Three writing habits to avoid

These habits can make a response harder to understand:

  • Leaving the question partly unanswered.
  • Adding unrelated material just to increase length.
  • Reusing a memorised answer that does not fit the prompt.

Use remaining time to review your response. Correct missing punctuation, unclear sentences and obvious typos. There is no published automatic penalty for pressing Continue before the timer ends. Official Writing Sample guidance

Review before continuing

Use remaining time to check your answer. You do not need to fill every second with more text.

How Linguistic Academy helps you get the score you need
