Direct answer

The hidden Band 7 ceiling in Writing is usually fluent language masking incomplete Task Response, not “bad English.” Essays sound Band 7 in vocabulary and sentence variety but miss prompt parts, thin overviews in Task 1, or list-like Task 2 bodies without sustained argument. Examiners cap TR/CC at 6 while LR/GRA look stronger, overall Writing sticks at 6.5. Fix the invisible criterion leak, not more idioms.

Three hidden ceilings that block Band 7

AI and teachers often praise grammar while TR stays at 6, see Writing AI limits.

Partial prompt Task 2 answers one part of a two-part question

Thin overview Task 1 lists features without a clear overview sentence

List logic Moreover chains without paragraph roles or development

Signals you hit a Band 7 ceiling

Signal	What it looks like	Fix focus
AI says 7, mock says 6.5	Fluent LR/GRA, weak TR	Prompt checklist per essay
Same TR comment every essay	“Develop more”	One idea per body paragraph
Task 1 stuck at 6	No overview line	Write overview before details

Break the ceiling in one week
