Coherence and Cohesion is the criterion most candidates misunderstand. The common belief is that higher Coherence scores come from using more linking words ("furthermore", "moreover", "in addition"). The opposite is true: heavy connector use caps your Coherence score at 6.5-7.0 because the examiner reads it as "I have memorised Band-7 connectors" rather than "I have a clear argument". The 8.0+ essay uses connectors sparingly and replaces them with logical reference. This guide shows you how.

What Coherence Actually Measures

The official Coherence and Cohesion descriptor at Band 7.0 says: "logically organises information with clear progression; presents a clear central topic within each paragraph; uses a range of cohesive devices appropriately though with some under/over-use."

Three things to notice. First, "clear progression" — the reader can follow the argument from one paragraph to the next. Second, "clear central topic" in each paragraph — the paragraph has a point. Third, "range of cohesive devices... with some under/over-use" — using the same connector three times is "over-use"; using six different rare connectors is "under-use" because they stand out as memorised. The sweet spot is 3-4 different cohesive strategies, used naturally.

The Four Cohesive Strategies (Not "Linking Words")

Coherence and Cohesion is built from four strategies, only one of which is "linking words". Most 8.0+ essays use all four. Most 6.0-7.0 essays use only the first.

Strategy 1: Connectors (used sparingly)

Connectors are explicit signposts: "however", "therefore", "as a result". They are the most visible cohesive device, which is why candidates over-rely on them. The 8.0+ candidate uses 3-4 different connectors per essay, not 8-10. Pick a small set and use them well.

Useful connectors: however, therefore, as a result, in contrast, similarly, moreover, consequently, on the other hand, despite this, even so. Avoid: firstly, secondly, thirdly, furthermore, in addition, what is more, to begin with, to sum up, in a nutshell. The first list signals academic writing; the second list signals "I learnt these in a Band-7 template".

Strategy 2: Logical reference (the 8.0+ move)

Logical reference means using pronouns and demonstratives to refer back to ideas you have already established. This is what replaces connector stacking in 8.0+ essays. Compare:

Low-band version: "Many countries are now investing in renewable energy. Furthermore, this trend is accelerating. In addition, it is supported by government policy. Moreover, the costs of renewables have fallen."

8.0+ version: "Many countries are now investing in renewable energy. The trend is accelerating, supported by falling costs and explicit government policy. The result is a structural shift in how energy is produced — one that is unlikely to reverse."

The second version uses no connector between the second and third sentences. The logic carries the cohesion forward. The examiner reads this as "I am a writer"; the first version reads as "I have memorised connectors".

Strategy 3: Lexical cohesion (the 9.0+ move)

Lexical cohesion means using synonyms, antonyms, and word-family forms to create ties between sentences without using pronouns or connectors. Compare:

Low-band version: "Schools should teach financial literacy. Schools currently focus on academic subjects. Schools should add financial literacy to the curriculum. This would help students."

9.0+ version: "Schools should teach financial literacy. The current curriculum prioritises academic subjects, but a financially literate population is essential to long-term economic resilience. Integrating these concepts would not displace traditional learning; it would complement it."

"Schools" is replaced by "current curriculum", "the curriculum", "integrating these concepts" — three different ways of referring to the same idea. The 8.0+ writer does this naturally; the 6.0-7.0 writer repeats the noun. The repetition is what makes the 6.0-7.0 essay read as mechanical even when the grammar is fine.

Strategy 4: Paragraphing (the most under-used strategy)

Most candidates think of paragraphing as "introduction, body, body, conclusion" — four paragraphs. The 8.0+ candidate thinks of paragraphing as one idea per paragraph, signalled by the topic sentence. A paragraph that contains two ideas is scored as having a weaker central topic, which directly lowers Coherence. Even a 5-sentence paragraph is read as under-developed if those 5 sentences make two different points.

The test: read any paragraph from your essay aloud. If you can describe the paragraph's central topic in 5-8 words, the paragraph is well-structured. If you cannot, the paragraph is doing two jobs and the examiner will mark it down.

10 Example Sentences That Score Band 8+ on Coherence

Each example shows a sentence using one of the four strategies. The "why it works" explains what the examiner sees.

"The policy, while well-intentioned, has had the unintended consequence of widening the very gap it was designed to close." — Logical reference ("it") plus a contrasting connector ("while"). The sentence does two jobs in one.
"This pattern is not unique to the education sector; healthcare systems in three OECD countries have produced remarkably similar reforms." — Lexical cohesion ("education sector" → "healthcare systems") plus a structural signal ("This pattern is not unique to").
"The result is a structural shift in how energy is produced — one that is unlikely to reverse." — Logical reference plus an appositive ("one that"). The em-dash creates a pause that signals a new claim.
"What is striking about the data is not the overall trend but the regional variation hidden within it." — Cleft sentence plus logical reference. The structure itself is the cohesion.
"The implications of this position are twofold. The first is regulatory; the second is cultural." — Topic sentence that previews the paragraph's structure. The reader knows exactly what is coming.
"Such a policy, while economically attractive in the short term, would impose costs that fall disproportionately on lower-income households." — Logical reference plus a concessive clause. The complexity of the sentence signals Band 8+.
"Consider the case of Kenya between 2007 and 2015, when mobile banking reached 70% of adult users in a country with no traditional banking infrastructure." — Lexical cohesion through specific dates plus a topic sentence that previews a single concrete example.
"The same logic that has driven the decline in print media applies, with greater force, to the decline in physical retail." — Lexical cohesion ("print media" → "physical retail") plus a connector ("applies, with greater force, to").
"It is worth noting that this view assumes a particular model of human decision-making — one in which people respond primarily to economic incentives — which is itself contested." — Multiple logical references plus a parenthetical concession. This is a 9.0 sentence.
"If the proposed policy is to succeed, three conditions must be met: sufficient funding, political continuity, and public acceptance." — A topic sentence that previews a list. The reader knows the structure before reading the body of the paragraph.

Why "Furthermore" Caps Your Score at 7.0

The single most common Coherence mistake is over-using connectors. The pattern is recognisable: every sentence in a body paragraph begins with "Furthermore", "In addition", "Moreover", or "What is more". The examiner's reading: "This candidate knows that Band 7 essays use connectors. This candidate does not know how to organise an argument without them."

Connectors are signposts that say "I am about to make a new point". When every sentence is a new point, the argument has no flow. The 8.0+ essay signals new points with paragraph structure, topic sentences, and logical reference — and uses connectors only at the paragraph-to-paragraph boundary, not within the body of a paragraph.

A Re-Write Exercise

Take a paragraph you have written recently. Count the connectors. If you have more than 2 in a 5-sentence paragraph, replace at least one with logical reference. Read the paragraph aloud. If the connector was doing real work (e.g. signalling a real contrast), keep it. If the connector was just a habit, replace it. The exercise takes 3 minutes and usually drops the connector count by 30-40% without losing meaning.

Frequently Asked Questions

How many linking words should I use in a 280-word essay?

4-6 different connectors, used sparingly. Using 10 different connectors is more harmful than using 3, because the variety itself signals "I have memorised a connector list". Stick to 3-4 high-quality ones: however, therefore, as a result, in contrast. The rest of your Coherence should come from logical reference and lexical cohesion.

Should I start every body paragraph with a connector?

No. The 6.0-7.0 candidate starts every body paragraph with "First, I will discuss..." or "To begin with..." or "Another important point is...". The 8.0+ candidate starts with a topic sentence that states the paragraph's point. The transition between paragraphs is then handled by logical reference, not by an explicit connector.

Is "However" overused? Should I avoid it?

"However" is the most useful connector in English because it signals a real contrast. Use it once or twice per essay, in places where you are genuinely contrasting two ideas. Avoid using it to start a sentence that does not contrast: "However, many people believe..." is a weak opening because "many people believe" is not a contrast, it is a setup.

What about paragraph length? Is 5 sentences enough?

Yes, if those 5 sentences are about one idea. A 5-sentence paragraph with a clear topic sentence, a developed example, and a link back to the position is more coherent than a 9-sentence paragraph that wanders. The mistake to avoid: writing 9 sentences because you think "longer is better". It is not. Five focused sentences score higher than nine unfocused ones.

How do I know if my Coherence is at 7.0 or 8.0?

Read any body paragraph aloud. If you can summarise the paragraph in 5-8 words without losing the main point, your paragraph has a clear central topic (7.0+). If you use 3+ different cohesive strategies (logical reference, lexical cohesion, paragraphing, connectors) in the same essay, you are operating at 8.0+ level. If your essay relies on a single strategy (almost always connectors), you are at 6.0-6.5.
