DET Writing Score Tips: How the AI Grades You and How to Beat It
The DET writing section is graded by AI, not a human examiner. That changes everything about how you should write. Learn the exact word counts, sentence structures, and transition words the algorithm rewards in 2026.
Why writing scores stay lower than they should
Most test takers lose writing points for the same two reasons and neither has anything to do with their English level.
First, they chase the perfect word. The clock ticks. Thirty seconds pass. They write a sentence, delete it, rewrite it, and end up with three sentences when they needed ten. The timer runs out before the algorithm ever sees what they can really do.
Second, they write the way a human teacher taught them. Vary your vocabulary. Avoid repetition. Use complex grammar. But the DET is not graded by a human teacher. It is graded by an AI engine. The AI rewards different things and it does so consistently.
The scoring system cares most about structure and volume. A well-organized response that hits the right word count scores higher than a beautifully written one that is too short. It does not matter how impressive your vocabulary is if the algorithm cannot read enough text to measure it.
The DET is also adaptive. Your performance on early writing tasks sets the difficulty level and scoring ceiling for the tasks that come later. A weak photo description does not just lose you points on that question. It tells the system to give you easier follow-up prompts, which carry lower scoring potential.
You can fix all of this today. The strategies below work because they give the algorithm exactly what it looks for.
Human examiner vs AI grader
A human examiner might appreciate clever phrasing. The DET AI does not. It scans for structural patterns, sentence variety, word count, and vocabulary range. Write for the machine, not for a teacher.
How the DET AI actually judges your writing
Before you learn the strategies, you need to understand what the algorithm measures. The DET AI looks at three things when it scores your writing.
Grammatical complexity. The AI checks whether you mix simple, compound, and complex sentences. If every sentence follows the same pattern (subject, then verb, then object), your score stays low even if your vocabulary is strong. You need variety. A short sentence. Then a longer one that combines two ideas with a connector. Then one that opens with a dependent clause.
Lexical diversity. This is where most advice gets it wrong. The AI does not reward fancy words. It measures how many different words you use. If you write 'important' three times in one paragraph, the diversity score drops. You do not need rare academic vocabulary. You need to avoid repeating yourself.
Task relevance. The AI runs a topicality check. If the prompt asks about remote work and you veer off into climate change, the algorithm flags your response as off-topic. Stay on the prompt. Use keywords from the question in your response.
Spelling and punctuation matter too, but the AI weights structure and vocabulary higher. A well-constructed response with one typo beats a messy response with perfect spelling.
These three factors determine most of your writing score. Every strategy in the sections that follow targets one or more of them.
The three things the AI measures
Grammatical complexity (mixing sentence types), lexical diversity (avoiding word repetition), and task relevance (staying on the prompt topic). If you satisfy all three, your score will reflect it.
Think like the algorithm
After you finish each response, ask yourself three quick questions. Did I use different sentence structures? Did I avoid repeating the same words? Did I stay on topic? If yes to all three, you are on track.
Write About the Photo: the 60-second formula
You get 60 seconds to describe a photo. Most people waste the first 20 seconds thinking. Then they write: 'There is a man with a laptop. There is a coffee cup.' That response will never score above the basic range.
The mistake is opening with 'There is.' The AI penalises this because it shows no grammatical variety. Every sentence has the same structure. Subject. Verb. Object. Repeat.
Use this formula instead.
Sentence 1: The main action. Use present continuous tense (is or are plus -ing). State who is doing what. Never open with 'there is' or 'I can see.'
Sentence 2: Key details. Add what you notice about the setting. Colors, textures, lighting, objects. Something that shows you studied the photo, not just glanced at it.
Sentence 3: A logical guess. Use words like might, could, or appears to. The AI rewards inference. It proves you can think beyond what is visible.
Here is the difference.
The strong response targets all three AI scoring factors. It opens with a descriptive subject rather than 'there is.' It mixes sentence structures. It speculates using appears to. All in three sentences.
Aim for 30 or more words total. Two sentences is not enough. Four is great if you have time. But three well-constructed sentences with this formula beats four rushed ones every time.
“There is a woman working on a laptop. There is a window. She looks busy.”
“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.”
The 'never start with' rule
Never begin with 'There is,' 'There are,' or 'I can see.' Start with the subject and an action. 'A young child runs across the field' instead of 'There is a child running.' One small change in sentence structure lifts your score immediately.
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
The Interactive Writing task changed the game. It is not one essay. It is two connected responses and the AI reads both together.
Here is how it works.
Part 1 gives you a prompt and 5 minutes. You write your response. Straightforward enough.
Then the system reads what you wrote and generates a follow-up question based on your answer. Part 2 gives you 3 minutes to respond. You cannot see Part 2 until you finish Part 1.
Most test takers empty the tank in Part 1. They use every argument, every example, every idea. When Part 2 asks them to expand, they have nothing left. They repeat themselves or write something weak. The AI sees the quality drop and scores both parts lower.
The fix is simple. Keep one good point in reserve.
In Part 1, give your main argument plus one supporting reason. Leave your second reason or a counter-argument for Part 2. The follow-up almost always asks you to elaborate or consider another angle. If you held back one idea, Part 2 writes itself.
An example. Say the prompt asks whether remote work is better than office work. In Part 1, argue that remote work offers flexibility and saves commuting time. But hold your point about how remote work can reduce company costs. When Part 2 asks you to expand, you have a ready-made second paragraph with fresh material.
Aim for 120 or more words across both parts combined. Part 1 is your longest section. Part 2 adds depth with the idea you reserved.
The reserve-one-point rule
Part 1: state your position, give reason 1, add a brief example. Part 2: give reason 2, connect it back to your position. Never use all your material in Part 1. The algorithm rewards consistent quality across both parts.
Repetition kills your score in Part 2
The AI detects when you restate what you already wrote in Part 1. Lexical diversity takes a double hit. Always add new information or a fresh angle in Part 2, never just rephrase your first answer.
The Writing Sample: your 3-minute micro-essay
The Writing Sample gives you 3 to 5 minutes to write on a single prompt. This is the task where word count matters most.
A response of 50 words caps your score at a mediocre level. It does not matter how perfect those 50 words are. The AI needs more text to measure your vocabulary range and grammatical variety. You cannot demonstrate what you know in 50 words.
Aim for 100 to 150 words. Use a simple three-part structure.
Part 1: Your position. One sentence that directly answers the question. No warm-up. No 'In my opinion.' Just your stance.
Part 2: Your evidence. Two to four sentences with an example or a reason. Invent a realistic scenario if you need to. The AI does not fact-check your examples. It checks whether you can organize and express an idea clearly.
Part 3: Your conclusion. One sentence that restates your position in different words. This also helps your lexical diversity score because you are saying the same thing with fresh vocabulary.
Three short paragraphs. That is the whole essay. The white space between them tells the AI that your writing has structure.
Keep typing until the timer runs out. Every second of unused time is a lost opportunity to add words and structure points. Never click submit early.
50 words caps your score
A flawless 50-word response will never reach a high score. The AI simply does not have enough data to measure your ability. Write until the timer stops. More text means more data, and more data means a higher score ceiling.
Words that raise your score (and words that do not)
Two changes to how you use words will lift your writing score noticeably.
Kill the contractions. The DET uses formal academic standards. Contractions signal informal writing to the AI. This change takes zero new vocabulary and works instantly.
Stop repeating yourself. The AI measures how many different words you use. If you write 'big impact' twice in the same response, swap one for 'significant effect.' If 'important' appears three times, use 'critical' or 'essential' for the repeats. You do not need rare academic vocabulary. You need to avoid reusing the same words.
Vary your transitions. If every paragraph opens with 'Also' or 'And,' the AI spots the pattern and your grammatical variety score drops. Rotate your transition words to show you can connect ideas in more than one way.
Here is a quick list of transitions the DET AI recognizes as higher-level.
- To show contrast
- Nonetheless, On the contrary, While some argue that
- To show cause and effect
- Consequently, As a result, This leads to
- To add a point
- Furthermore, In addition, What is more
- To give an example
- For instance, To illustrate, Consider the case of
Do not pack all of these into one response. Use one or two per task. The goal is variety, not density.
don’t, can’t, it’s, won’t, they’re
do not, cannot, it is, will not, they are
The fastest formality fix
Eliminating contractions is the single quickest change you can make. It requires no new vocabulary. You simply write the full words: do not, cannot, will not, it is, they are. Your score improves immediately.
Variety beats complexity
You do not need rare academic words to score well. You need to avoid using the same word twice. If you catch yourself repeating a word, swap the second occurrence for a synonym you already know. That is lexical diversity.
Three mistakes that drop your score immediately
Even if you write well, these three errors drag your score down. The AI catches them every time.
Submitting early. If you finish with time left on the timer and click submit, you lose word count potential. Less text means a lower ceiling on your score. Use every second. Write one more sentence. Proofread one more pass. Never submit early.
Starting every sentence the same way. The AI scans your sentence openers. If four of your five sentences start with 'I think,' 'Also,' or 'Moreover,' the grammatical variety score plummets. Mix it up. Start one with the subject. Start the next with a transition word. Start the next with a time clause like 'When students face this...'
Using copied templates. If you memorise a generic essay frame and force every response into it regardless of the prompt, two things happen. Your response sounds unnatural because it does not answer the specific question. And the AI can flag template-like patterns as off-topic or repetitive. Write fresh for each prompt.
Also save your last 30 seconds for proofreading. Not to catch every mistake. Just to spot missing periods, capital letters, and obvious typos. A clean response with two small errors scores higher than a sloppy response with clever ideas.
The submit button costs you points
Finishing with time left and clicking submit is like leaving points on the table. The AI needs text to evaluate. Every extra sentence gives it more data. More data means a fairer, and usually higher, score.
