Direct answer

Coherence and Cohesion measures whether a reader can follow your argument, not how many linking words you paste in. Examiners look for clear paragraph roles (position, reason, example, concession), logical progression between sentences, accurate reference (this policy, they), and cohesive devices that match meaning. Essays with flashy connectors but list-like bodies or drifting topic sentences typically stay at Band 6 CC even when vocabulary looks strong.

What CC descriptors reward

CC sits alongside Task Response, Lexical Resource, and GRA. A Band 7 CC essay presents information with clear overall progression; uses cohesive devices appropriately; and may have occasional lapses. See Task Response evaluation and coherence collapse under pressure.

Progression Each paragraph advances the thesis, not repeats it with synonyms

Reference Pronouns and determiners point to clear antecedents

Paragraphing One central idea per body paragraph with a visible topic sentence

CC traps examiners penalize

Student habit	Examiner read
Connector stuffing (Moreover, Furthermore…)	Mechanical, logic still unclear
Body = bullet list	No sustained development
New idea every sentence	No cohesive thread
Conclusion introduces new argument	Breaks progression

CC upgrade protocol

Outline: thesis + two topic sentences before writing.
Start each body paragraph with a line that names the paragraph job.
End paragraphs by linking forward: This is why governments should…
Cut connectors that do not change meaning, keep one per paragraph max unless contrast is real.

Key takeaways

CC = logical progression and clear reference, not connector count.
Topic sentences and paragraph roles matter more than Moreover.
List bodies rarely reach Band 7 CC.
TR answers the question; CC makes the answer followable.

FAQ

No. Mechanical connectors without logical progression often stay at Band 6; examiners reward clear paragraph roles and reference.

Yes. TR judges whether you answered the prompt; CC judges how clearly ideas connect inside that answer.

Rarely, list bodies lack sustained development and clear progression between ideas.
