IELTS Writing Task 2: Why You Stay at Band 6 and How to Reach Band 7

Understanding the Band 6 "Plateau"

For many IELTS candidates, Band 6 is the most frustrating hurdle. You have a decent command of English, you can write 250 words, and your grammar is mostly correct—yet the results remain the same. Breaking through to Band 7 requires a shift in mindset: moving from merely communicating ideas to constructing a sophisticated, logical argument.

To understand how to improve, we must look at the four official scoring criteria used by examiners. Often, the difference between a 6 and a 7 is found in the "gray areas" of development and precision.

Criterion 1: Task Response – Depth Over Breadth

At Band 6, candidates often address all parts of the question, but their ideas are "insufficiently developed." This usually happens when a writer lists three or four different points without explaining any of them in detail.

Band 7 Tip: Focus on one or two strong arguments per paragraph. Extend your ideas using the "Idea-Explain-Example" (IEE) method. This ensures your position is clear throughout the essay, which is a hallmark of a well-structured Band 7 response.

The Comparison

• Weak (Band 6): "One reason for pollution is cars. There are too many cars on the road today. This makes the air dirty and is bad for people's health."
• Better (Band 7): "The primary cause of urban air pollution is the excessive reliance on private vehicles. As cities expand, the density of traffic increases, leading to higher emissions of nitrogen dioxide. This not only degrades air quality but also triggers chronic respiratory illnesses among residents."

Criterion 2: Coherence and Cohesion – Beyond Logic Linkers

Band 6 writers often overuse "mechanical" cohesive devices (firstly, secondly, moreover, in conclusion) at the start of every sentence. While these are correct, they can feel repetitive and artificial.

To reach Band 7, you need to use referencing and substitution. Instead of repeating the "problem," use "this issue," "the aforementioned challenge," or "this predicament." Transitions should feel seamless. For more on refining your delivery, check out Mastering Academic Tone for Language Exams.

Criterion 3: Lexical Resource – Precision is Key

Many students believe that "big words" equal a high score. In reality, Band 7 is about collocation and precision. It is not just about knowing a word; it is about knowing which words it "likes" to hang out with. Using a word like "exacerbate" instead of "make worse" can elevate your writing instantly. You can learn more about this in our guide on Mastering the Word 'Exacerbate'.

Common Mistake: Using "rare" words incorrectly. If the word doesn't fit the context perfectly, it will actually lower your score. Always prioritize vocabulary precision over complexity.

Criterion 4: Grammatical Range and Accuracy

A Band 6 writer has good control over simple sentences but makes frequent errors when attempting complex structures. A Band 7 writer produces "frequent error-free sentences" and uses a variety of complex structures (conditionals, relative clauses, passive voice) naturally.
