Band 7 in IELTS Writing: What Separates It From 6.5

Band 7 is the number most candidates are actually chasing. It is the common requirement for skilled visa routes and for a large share of university programmes, and it sits just above where most competent writers land. A candidate at 6.5 is not far away, but the distance is not closed by writing more or by learning longer words.

This page is about the gap. For each of the four criteria, it names what a 6.5 answer typically does, what a 7 answer does instead, and the one change that moves it.

How the overall band is built

Writing is marked on four criteria, each given a whole band: Task Response (called Task Achievement in Task 1), Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. The four are averaged, and the average is rounded to the nearest half band. Task 2 counts twice as much as Task 1 in the writing total.

That arithmetic has a consequence worth understanding. Four sevens give you a 7. So do 7, 7, 7, 6, which averages 6.75 and rounds up. But 7, 7, 6, 6 averages 6.5 and stays there. One weak criterion is survivable; two are not. If you are stuck at 6.5, the efficient move is usually to find your lowest criterion and lift it, rather than to polish the criterion you are already strongest at. The overall band calculator shows the combinations.

Task Response

At 6.5. The question is addressed, and all parts are covered, but some ideas are stated and then left. A paragraph makes a claim, adds a sentence that repeats the claim in other words, and moves on. The position is present but may drift: stated in the introduction, softened in the middle, restated slightly differently at the end.

At 7. Every main idea is extended and supported. The position is clear throughout, and it is the same position in all four paragraphs.

The change. After each claim in your body paragraphs, ask one question: so what? Write the answer as the next sentence.

Here is the difference on one idea.

6.5. Public transport should be cheaper. If tickets cost less, more people would use public transport instead of cars.

7. Public transport should be cheaper. A fare that is lower than the cost of fuel and parking changes the daily calculation for a commuter who currently drives, and it changes it every day rather than once, which is why price works where appeals to environmental duty do not.

The second version has one idea, not two. It develops it. That is what the descriptor means by extended and supported.

Coherence and Cohesion

At 6.5. The essay is organised and the reader can follow it, but the connections are mechanical. Firstly, secondly, moreover, in addition, in conclusion. Paragraphing is present but sometimes a paragraph holds two ideas, or one idea runs across two paragraphs.

At 7. Information is sequenced logically, each paragraph has one clear central topic, and cohesion is managed with reference and substitution rather than with a connector at the front of every sentence.

The change. Delete every linking word at the start of a sentence, then reread. Most of the sentences will still connect, because the ideas were already in order. Where a sentence now floats, reconnect it by referring back to a noun from the previous sentence instead of by adding moreover.

6.5. Moreover, this policy is expensive. In addition, it is difficult to enforce.

7. The policy is also expensive, and its cost is hard to justify when enforcement is this difficult.

Two mechanical connectors gone, one sentence, and the relationship between cost and enforcement is now stated rather than implied. There is more on this in coherence and cohesion.

Lexical Resource

At 6.5. Vocabulary is sufficient, with some attempts at less common words. The attempts are where the errors are. A candidate reaches for plethora, detrimental or myriad and uses it in a collocation that a native reader would not produce. Topic words repeat: environment appears nine times.

At 7. There is a sufficient range to allow some flexibility and precision, some less common items are used, and although there are occasional errors in word choice or collocation they do not impede communication.

The change. Stop hunting for impressive words and start hunting for precise ones. Precision usually means an ordinary word in an exact place.

Notice that no word in the right hand column is rare. The gain is in specificity. The other half of the work is collocation, which is the pairing of words that normally go together; collocation and lexical resource covers how to build that.

Grammatical Range and Accuracy

At 6.5. A mix of simple and complex sentences, with errors that are noticeable but rarely block meaning. The recurring ones are almost always the same short list: articles, subject verb agreement in long sentences, and prepositions after specific verbs.

At 7. A variety of complex structures, frequent error free sentences, and good control of grammar with only a few errors.

The change. Frequent error free sentences is the phrase to focus on, because it is measurable in a way the rest is not. Take a practice essay you have already written. Count the sentences. Count how many have zero errors. If fewer than half are clean, more complex structures will not help you; accuracy will.

Two habits do most of the work here. First, keep long sentences under about twenty five words, because agreement errors cluster in the long ones. Second, learn your own three most common errors rather than grammar in general. Most candidates have three, they repeat in every essay, and they are usually articles, plurals or tense consistency. Grammar errors that hold essays at band 6 lists the frequent ones.

The order to work in

1. Find your lowest criterion. Not your worst feeling, your lowest score.
2. Fix accuracy before range. A clean simple sentence outscores a broken complex one on every criterion at once, because an error in grammar often also obscures the idea.
3. Develop ideas before adding them. Three developed ideas beat six listed ones.
4. Strip connectors. This is the fastest single change on Coherence and Cohesion, and it takes one pass.
5. Rewrite the same essay rather than writing a new one. The second version of an essay you have already planned is where the learning is.

What to do today

Take your most recent practice answer. Count the error free sentences, then pick the single paragraph with the least development and add one so what sentence to each claim in it. Those two actions target the two criteria that most often sit at 6.

Then put the rewritten version through Bandly and compare the four criterion bands against the original. The scores are estimates from a model rather than marks from a qualified examiner, so the number to watch is not the overall band but whether the criterion you worked on moved.
