At English AIdol, our AI-powered IELTS writing scorer has evaluated 242 IELTS Writing Task 2 essays from real students. Every essay was submitted voluntarily, scored by our AI engine, and given detailed feedback aligned to the four IELTS band criteria (Task Response, Coherence and Cohesion, Lexical Resource, Grammatical Range and Accuracy).
This post shares the aggregate patterns we observed. All individual essays remain private — we report only statistical summaries.
The most surprising result from our analysis is how tightly clustered student essays are around the 300-word mark.
| Word Count Range | Number of Essays | Percentage | |---|---|---| | Under 250 | 3 | 1.2% | | 250–299 | 69 | 28.5% | | 300–349 | 144 | 59.5% | | 350–399 | 23 | 9.5% | | 400+ | 3 | 1.2% |
Mean: 305 words. Median: 305 words. The distribution is almost perfectly centered on the unofficial "sweet spot" that IELTS prep blogs have been recommending for years.
Only 3 essays out of 242 (1.2%) fell below the official 250-word minimum. This tells us that most serious IELTS candidates now understand the word-count rule — the anxiety around "writing enough" is largely solved.
Here's what most IELTS blogs get wrong: they tell students to aim for 280-320 words without explaining why exceeding that range doesn't help.
In our data, essays in the 300-349 word range scored highest on average. Essays above 400 words actually scored lower than essays at 300 words. Our hypothesis: students who write excessively long essays are usually padding with filler phrases that hurt Coherence and Cohesion and Lexical Resource scores.
Takeaway for test-takers: Stop writing to hit 350+ words. Aim for 290-320. Spend the remaining time on editing instead.
Across the essays where we parsed individual criterion scores, the strongest correlation between final band and individual criterion was with Task Response — not grammar, not vocabulary.
Students whose Task Response scored band 7+ almost always achieved an overall band 7 or higher, even when their Grammar scored 6.0. Conversely, students with brilliant grammar (band 8+) but weak Task Response (band 6) rarely broke band 7 overall.
Why: IELTS scoring is based on the lowest of the four criteria, roughly speaking. A single weak category pulls the overall band down. But Task Response is special because it measures whether you actually addressed the question, which a lot of students misread in the 2-minute planning phase.
Takeaway: Spend the first 3-4 minutes of Task 2 planning. Re-read the prompt twice. Identify exactly what you're being asked (agree/disagree, discuss both views, advantages/disadvantages, etc.) before writing a single word.
Our feedback engine flagged the same errors repeatedly across the 242 essays:
We also looked at 1,025 speaking responses across Parts 1, 2, and 3. Part 2 had the lowest average band score of the three parts.
Why? Part 2 requires sustained monologue for 1-2 minutes, while Parts 1 and 3 are interactive Q&A. Students who can maintain a conversation struggle when they have to generate continuous speech on an unfamiliar topic without prompts.
Takeaway: If you're stuck at a band, Part 2 is usually the weakest link. Drill cue cards daily and force yourself to talk for the full 2 minutes even when you want to stop at 90 seconds.
