Many strong writers stay at Band 6 because their essays look correct but fail descriptor depth: template introductions, three vague body points, and conclusions that repeat without advancing the argument. Examiners cap Task Response and Coherence when the position is unclear, support is generic, or parts of the prompt are missing. Grammar can look fine while TR/CC stay at 6, creating a hidden ceiling.

Writing patterns that cap at Band 6
| Pattern | Why it feels good | Examiner cap |
|---|---|---|
| Template intro + opinion | Looks academic | TR, no real engagement with task nuance |
| Three generic body points | Looks organized | CC, lists, not progression |
| Memorized linking phrases | Looks cohesive | CC, mechanical jumps |
| Rare vocabulary spikes | Looks advanced | LR, accuracy over display |
Task Response leaks at Band 6
Band 6 TR: addresses the task but development is uneven or parts are thin. Band 7 TR: clear position throughout with extended support. See task achievement vs task response.
Coherence without real progression
Paragraphs that start with Moreover/Furthermore but add no new reasoning stay at Band 6 CC. Band 7 needs logical chains: claim → reason → example → mini-conclusion.
Break the Band 6 ceiling
1. Underline every task sentence
Map each requirement to a paragraph, gaps show TR leaks.
2. One idea per paragraph, fully developed
Replace three thin points with two developed arguments.
3. Blind rewrite
New prompt, no templates, see if Band 7 behaviours survive.
Key takeaways
- Band 6 Writing ceilings are usually TR/CC depth, not grammar alone.
- Templates and list structures mimic organization without Band 7 development.
- Examiners cap scores when support is generic or parts are missing.
- Fix with task mapping and fully developed paragraphs on blind prompts.
