IELTS Band 7 Essay Sample vs Band 6: A Clear, Criterion-by-Criterion Comparison
Two essay excerpts. The same Task 2 prompt. A one-band difference in score.
In this article, you will see excerpts from a Band 6 response and an IELTS band 7 essay sample for the same question, then work through each of the four official IELTS Writing criteria to see precisely what changed. Not vague advice about writing longer sentences or using a bigger vocabulary. The specific, criterion-anchored differences that produce a full band improvement in the examiner’s assessment.
If you score Band 6 in Writing Task 2 and want to understand which habits to change before your next test, this comparison gives you a diagnostic framework rather than a model answer to copy.
What an IELTS Band 7 Essay Sample Reveals About the Band 6 to Band 7 Step
A Band 6 writer and a Band 7 writer are not separated by a dramatic skills difference. The candidate at Band 6 typically has adequate vocabulary, uses linking phrases, and avoids serious grammatical errors. The distance lies in precision and consistency across all four criteria that IELTS examiners assess equally: Task Response, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy.
Each criterion contributes 25% to the final Writing Task 2 band score. A candidate who performs strongly on three criteria but weakly on one does not average out to Band 7. All four must reach the threshold together. IELTS test-taker performance data at ielts.org shows Writing consistently produces the lowest mean scores of all four skills.
What any genuine IELTS band 7 essay sample reveals is not a single impressive feature but consistent performance across all four measures simultaneously.
The Prompt Both Essays Answer, and Why It Matters
Most essay comparisons show a Band 5 or 6 essay on one topic and a Band 7 model on a different one, which skews the result. Both extracts use the same question, so the comparison is about execution, not topic.
Both essays excerpted here answer the same question: “Some people believe technology has made people’s lives better. Others feel it has made them worse. Discuss both views and give your own opinion.”
This is a typical two-part opinion prompt requiring discussion of both views and a maintained position. The comparison below focuses on how each writer executed the same task.
Task Response: What the Band 7 Essay Does That Band 6 Does Not
Band 6 introduction:
“Technology has become a big part of modern life. It has many advantages but also disadvantages. In my opinion, I think technology has made life better, but there are some negative effects too.”
Band 7 introduction:
“Technology now shapes almost every aspect of daily life, from how we communicate to how we access healthcare. While critics highlight social and economic costs, the case for technology’s positive impact is stronger when examined systematically.”
Both introductions address the topic. The difference lies in task coverage and position clarity.
The Band 6 writer states a view but does not signal that both views will be developed. The phrase “but there are some negative effects too” is an acknowledgement, not a discussion of the opposing argument. According to the IELTS Writing band descriptors, published jointly by British Council, IDP: IELTS Australia, and Cambridge English, a Band 7 response addresses all parts of the task and maintains a clear position throughout. The Band 7 introduction signals this from the first sentence.
Coherence and Cohesion: How the Band 7 Essay Flows Without Repetition
Band 6 body paragraph:
“On the one hand, technology makes our lives easier. For example, we can communicate with family quickly using smartphones. Also, we can find information online. In addition, technology in hospitals helps doctors treat patients.”
Band 7 body paragraph:
“Those who argue technology has worsened daily life typically point to two changes: the shift from face-to-face interaction to screen-based communication, and the displacement of workers through automation. These concerns are real, but they describe consequences that policy can address rather than evidence that technology is harmful by nature.”
The Band 6 paragraph strings three separate examples using additive connectors at sentence openings. The official IELTS Writing band descriptors describe this pattern as “mechanical use of cohesive devices” at Band 6, where devices are used repetitively rather than to show logical relationships. Band 7 uses cohesive devices “flexibly” and organises information with “clear progression throughout.”
No connector appears twice, and the paragraph develops one claim logically rather than listing equivalents. For more on how paragraph organisation affects Writing Task 2 scores, see the IELTS Writing Task 2 essay structure guide on Speechful.
Lexical Resource: How an IELTS Band 7 Essay Sample Uses Vocabulary Differently
The most visible vocabulary difference in these samples is precision, not rarity.
Band 6 vocabulary: “big part,” “makes our lives easier,” “helps doctors treat patients.” Grammatically correct but semantically general.
Band 7 vocabulary: “shapes almost every aspect,” “displacement of workers through automation,” “consequences that policy can address.” Each phrase specifies a mechanism or draws a logical relationship. “Displacement” names the economic process precisely; “consequences that policy can address” draws a causal distinction rather than making a general claim.
The official IELTS band descriptors (British Council, IDP: IELTS Australia, and Cambridge English) describe Band 6 Lexical Resource as showing “inappropriacies” in word choice alongside vocabulary that is “generally appropriate,” while Band 7 includes the use of “less common lexical items” with “some awareness of style and collocation.” The Band 7 sample is not using rare words: it is using precise ones in correct collocations. That distinction is what the descriptors reward.
Grammatical Range and Accuracy: Why Variety Matters as Much as Correctness
Look at the sentence structures across both samples.
Band 6 sentences follow a simple subject-verb pattern throughout: “Technology has become a big part of modern life.” “It has many advantages but also disadvantages.” “We can communicate with family quickly using smartphones.” There are no errors. There is also no range.
Band 7 sentences vary in structure. The second sentence opens with a concessive clause: “While critics highlight social and economic costs, the case for technology’s positive impact is stronger when examined systematically.” The body paragraph opens with a relative clause: “Those who argue technology has worsened daily life typically point to two changes.”
The official IELTS band descriptors describe Band 6 as producing “a mix of simple and complex forms” with “some errors in complex structures,” while Band 7 shows “a variety of complex structures” with “frequent error-free sentences.” Accuracy without range scores Band 6. Both together form the threshold for Band 7.
The Habits That Keep Most Writing Task 2 Candidates at Band 6
Four patterns appear across Band 6 scripts consistently enough to be diagnostic.
Additive connector overuse. Placing back-to-back sentence-opening connectors (“Also,” “In addition,” “Besides this”) creates a list where an argument should develop. The band descriptors associate this with “mechanical use of cohesive devices” at Band 6. Each additive connector signals equivalence between ideas rather than logical progression.
Vocabulary repetition. Using the same word or phrase across body paragraphs (“important,” “affects,” “make life better”) signals limited Lexical Resource regardless of how accurate the surrounding sentences are.
Partial task address. A “discuss both views” prompt requires genuine development of each view across dedicated paragraphs, not one substantial section and one brief acknowledgement. The descriptors associate partial address with Band 5 to 6.
Position drift. Stating a view in the introduction but not maintaining it in the body or conclusion is a Task Response weakness. For how to build position consistency into a full essay structure, see the agree-or-disagree IELTS essay guide on Speechful.
What Most Test-Prep Guides Get Wrong About Reaching Band 7
Two pieces of Band 7 Writing advice appear across most preparation materials: use a wider vocabulary and write a longer essay. Both are incomplete, and following either without understanding the criteria can lower a score rather than raise it.
The official IELTS Writing band descriptors, available at ielts.org, measure Lexical Resource on precision and collocational accuracy, not vocabulary size. Inserting a rare word into the wrong collocation is not a Band 7 signal. The descriptors specifically name “inappropriacies” in word choice at Band 6. Using a precise, common word in the correct collocation scores better than using a sophisticated word incorrectly.
Length is not a scoring criterion. An essay of 400 words that repeats the same points scores lower on Task Response than a 280-word response that addresses the question fully with developed reasoning.

How Long Does Moving from Band 6 to Band 7 in Writing Task 2 Typically Take?
There is no honest universal answer, and any source that promises a specific timeframe should be read with care.
For a Band 6 candidate with consistent practice, a realistic range is four to twelve weeks. Task Response issues tend to close quickly because the problem is visible: either both parts of the prompt are addressed or they are not. Coherence and Cohesion improvements take longer because the problems are harder to detect in your own writing.
What consistently accelerates progress is criterion-specific feedback on real essays rather than reading more model answers. Identifying the specific criterion and practising against it moves a score more reliably than general essay practice.
How to Assess Your Own IELTS Writing Task 2 Score Before the Exam
After reading an ielts band 7 essay sample alongside its Band 6 counterpart, the practical step is applying the same four-criterion framework to your own writing.
Work through one paragraph at a time. For Task Response, underline each instruction in the prompt and check whether your paragraphs address it explicitly. For Coherence and Cohesion, read each paragraph in isolation and check whether the sentences develop a single point or list separate claims. For Lexical Resource, highlight vocabulary choices and ask whether each word fits its precise collocation. For Grammatical Range and Accuracy, identify how many different clause structures appear across the paragraph.
Speechful’s IELTS Writing AI grader applies the same four criteria to every Task 2 essay you submit, with sentence-by-sentence feedback that identifies which specific criterion is costing marks. Practise against the same framework examiners use at speechful.ai/ielts-ai.
Frequently Asked Questions
What’s the main difference between a Band 6 and Band 7 IELTS essay?
The difference isn’t a dramatic skills gap. It’s precision and consistency across all four IELTS Writing criteria: Task Response, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. A Band 6 writer typically has adequate vocabulary and avoids serious errors, but a Band 7 essay performs consistently well across all four criteria at once, rather than excelling in one and lagging in another.
Do I need a bigger vocabulary to reach Band 7 in IELTS Writing?
No. The official band descriptors measure Lexical Resource on precision and correct collocation, not vocabulary size. Using a common word in the right collocation scores better than using a rare word incorrectly. Inserting sophisticated vocabulary into the wrong context is specifically flagged as an “inappropriacy” at Band 6, not a Band 7 signal.
Does writing a longer essay improve my IELTS Writing Task 2 score?
No. Length is not a scoring criterion. A shorter essay that fully addresses the question with developed reasoning scores higher on Task Response than a longer essay that repeats the same points without adding depth.
How long does it take to go from Band 6 to Band 7 in Writing Task 2?
For a candidate practising consistently, a realistic range is four to twelve weeks. Task Response issues tend to improve faster since the problem is visible: either the prompt is fully addressed or it isn’t. Coherence and Cohesion improvements typically take longer, since these issues are harder to spot in your own writing without feedback.
How is IELTS Writing Task 2 scored?
Task 2 is scored across four criteria, each contributing 25% to the final band: Task Response, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. All four must reach a given band threshold together. Strong performance in three criteria doesn’t average out to a higher score if the fourth is weak.
