How BAND9AI Scores IELTS Writing Practice
TA/TR · CC · LR · GRA · May 2026
In Band9AI first-party platform telemetry (see methodology), writing candidates flagged at Band 5–6 most often leak marks through task response under-development in Writing Task 2. This is an observational practice metric, not a controlled trial or guaranteed official IELTS lift. Verification methodology

BAND9AI scores Writing practice on the four IELTS Writing criteria — Task Achievement or Task Response, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy — with leak notes tied to those descriptors, not a grammar-only tick. The overall practice band is a study composite. It is not your TRF. Use the lowest criterion as the next drill; do not shop for a friendlier chatbot number.
Part of the IELTS Writing Guide: every writing trap, band descriptor and practice drill in one place.

From submission to four notes
You submit Task 1 or Task 2 under the product flow. Feedback is organised like examiner criteria so you can see whether the leak is overview (TA), position (TR), paragraphing (CC), or error density (GRA).
How to use Writing sub-scores
| Criterion | Typical leak | Next drill |
|---|---|---|
| TA (Task 1) | No overview / no comparison | 60-second two-pole overview |
| TR (Task 2) | No stance / off-prompt | Write the stance before body 1 |
| CC / LR / GRA | Bullets, repetition, error clumps | One criterion per week, not all three |
A week on one Writing leak
1. Trust the lowest criterion
A pretty GRA cannot rescue missing TR.
2. Rewrite the same prompt type
New topic, same question shape.
3. Time both tasks
Untimed essays inflate CC.
4. Keep chat polish out of the scored sit
You need the score of your unassisted text.
Key takeaways: How BAND9AI Scores IELTS Writing Practice
- Four criteria, not a vibe band.
- Lowest leak is the syllabus.
- Practice ≠ TRF.
- Task 1 TA and Task 2 TR are different jobs — see the vary-between-tasks note.
