Why Your IELTS Writing Score Is Stuck at 6.5 (The Truth Examiners Don’t Tell You)

It’s frustrating, and it makes you wonder: What is the secret ingredient I’m missing?

The truth is, moving from a 6.5 to a 7.0 and beyond isn’t about writing more; it’s about writing differently. It requires a fundamental shift from being a “good” writer to a “strategic” one. As examiners, we assess against a strict set of public criteria, but the subtle difference between a 6.5 and a 7 often boils down to a few critical, unspoken nuances that most candidates never hear about.

This article will decode those nuances and give you a clear, actionable roadmap to finally break the 6.5 barrier for good.

The 6.5 Candidate vs. The 7.0 Candidate: A Fundamental Mindset Shift

Think of the Band 6.5 candidate as a competent driver. They know the rules of the road, can operate the vehicle safely, and get from point A to point B without major accidents.

The Band 7.0 candidate, however, is a defensive driver. They not only know the rules but also anticipate the actions of others, smooth out the ride for their passenger (the examiner), and navigate complex junctions with effortless confidence and control.

The difference isn’t just skill—it’s heightened awareness and deliberate control. Let’s break this down across the four marking criteria.

1. Task Achievement (TA): The Critical Difference Between “Mentioning” and “Exploring”

The 6.5 Problem: You address all parts of the task, but you don’t fully address them. This is the most common, and most misunderstood, distinction. A 6.5 response mentions all the points in the question. A Band 7 response explores and develops them.

Let’s Break It Down with an Example:

Task: Some people believe that the best way to reduce crime is to give longer prison sentences. Others, however, believe there are better alternative methods. Discuss both views and give your own opinion.

The Typical 6.5 Approach:

• You write one paragraph about longer sentences (it’s a deterrent, it keeps criminals off the streets).
• You write another paragraph about alternatives (rehabilitation, education programs).
• You present ideas, but they remain general and lack depth. The connection between an idea and its effect is often assumed, not explained.

The Strategic 7.0+ Approach:
You go beyond simply listing ideas. You explain the underlying logic and consequences.

• For longer sentences, you don’t just say “it deters crime.” You explain the theory of deterrence: that the fear of a harsh punishment can discourage potential offenders. You might also mention incapacitation—how imprisonment physically prevents criminals from re-offending during their sentence.
• For alternatives, you don’t just list “education.” You discuss how education reduces crime by tackling root causes like poverty and lack of opportunity, which leads to lower recidivism rates in the long run.
• You make the link between your point and its outcome explicit and logical.

The Examiner’s Truth: We see countless essays that are a collection of related ideas, but not a coherent, developed argument. To cross into Band 7, you must prove you can extend and support a main idea with a clear reason or a specific example, not just state it.

2. Coherence and Cohesion (CC): The Art of Creating a Seamless Flow

The 6.5 Problem: You use linking words, but you overuse the same basic ones, occasionally misuse them, or create a structure that feels mechanical rather than fluid. Your paragraphing is logical, but the internal logic and flow within each paragraph is weak. A 6.5 essay often feels like a checklist. A Band 7 essay feels like a guided journey.

The 6.5 vs. 7.0 Breakdown:

The 6.5 Approach:

• Reliance on basic, repetitive sequencers: “Firstly, Secondly, Finally, In conclusion.”
• Overuse of “Furthermore,” “Moreover,” and “In addition” to connect sentences.
• Paragraphs have a topic sentence, but the following sentences may not build on each other seamlessly. The “flow” is created by links, not by ideas naturally progressing.

The 7.0+ Approach:

• You use a wider range of sophisticated cohesive devices effortlessly. This includes:

Pronouns and referencing: “This policy,” “Such an approach,” “These methods.”

Synonym substitution: Repeating key nouns without being repetitive.

Conjunctive adverbs: “Consequently,” “However,” “Therefore,” “Notwithstanding this.”

• Your paragraphs follow a powerful “mini-essay” structure: a clear topic sentence, a sentence that explains or expands on that idea, a specific example to illustrate it, and a concluding sentence that ties the paragraph’s message back to the main question.

The Examiner’s Truth: We are trained to spot “mechanical” linking. Using “On the one hand” correctly is fine, but it doesn’t impress. Using “Conversely” or “Notwithstanding this argument” appropriately does. The flow should feel natural and intelligent, not forced and formulaic.

3. Lexical Resource (LR): Why Precision Beats “Big Words” Every Time

The 6.5 Problem: You operate under the damaging myth that using “big words” will automatically get you a high score. Consequently, a 6.5 essay often has flashes of advanced vocabulary but is let down by frequent collocation errors and awkward phrasing that feels unnatural.

The 6.5 vs. 7.0 Breakdown:

The 6.5 Approach:

• You write “take a crime” instead of “commit a crime.”
• You describe a problem as “strong” instead of “serious” or “pressing.”
• You use words like “big” correctly, but in contexts where “major,” “significant,” or “considerable” would be more natural and academic.
• You make just enough “small” errors in word choice and partnership to keep you locked in Band 6.

The 7.0+ Approach:

• You prioritize accuracy and collocation above all else. Your vocabulary is less about showing off and more about using the precisely right word.
• You have a keen sense of which words live together. You know that you “implement a policy,” “adopt a strategy,” “introduce a program,” and “commit a crime.”
• You use less common, idiomatic vocabulary naturally and accurately, enhancing your message rather than obscuring it.

The Examiner’s Truth: An essay with simpler vocabulary that is used with perfect collocation and accuracy can easily score higher than an essay packed with ambitious but error-prone words. We are specifically marking for “awareness of style and collocation,” not just the size of your vocabulary.

4. Grammatical Range and Accuracy (GRA): Mastering Control Over Complexity

The 6.5 Problem: You can write complex sentences, but you make frequent, small grammatical errors. Alternatively, you play it too safe by using mostly simple and compound sentences to avoid mistakes, which caps your score. A 6.5 writer uses complexity with errors. A Band 7 writer uses complexity with control.

The 6.5 vs. 7.0 Breakdown:

The 6.5 Approach:

• You attempt relative clauses but occasionally misplace them (e.g., “I saw the dog on the television that was brown.”).
• You use conditional sentences but might mix up the Second and Third Conditional.
• Your essay has a few recurring errors like articles (a, an, the), preposition misuse, or subject-verb agreement in long sentences.
• The errors don’t prevent understanding, but they consistently prevent you from reaching Band 7.

The 7.0+ Approach:

• You confidently and accurately use a variety of complex structures throughout the essay. For example:

• Conditional Sentences: “If governments were to invest more in rehabilitation, recidivism rates would likely fall.”
• Relative Clauses: “The new policy, which was implemented last year, has already yielded significant results.”
• Participle Phrases: “Having considered both perspectives, I am convinced that alternative methods are more effective.”
• Passive Voice: “It is often argued that longer sentences are the most straightforward solution.”

• You produce frequent error-free sentences and have full control over grammar and punctuation.

The Examiner’s Truth: We are looking for a mix of sentence types used accurately. We don’t just tick a box for each complex sentence we see; we assess the overall density of complex structures and, more importantly, the accuracy of your grammatical choices. Control is everything.

Your 4-Step Action Plan to Break Through to Band 7+

Now that you understand the “what,” here is the “how.” Implement this plan consistently.

1. Prioritize Quality Over Quantity: Stop writing 10 full essays a week. Instead, write 2-3 essays, but then spend hours analyzing and rewriting them. Be your own toughest critic. This is where real improvement happens.

2. Master the “Why” and “How”: For every body paragraph you write, ask yourself: “Have I explained why this point is true or how it works?” If you haven’t, you’ve only stated an idea, not developed it. This is the key to Task Achievement.

3. Become a Collocation Collector: When you learn a new word, immediately learn its common partners. Use tools like a collocation dictionary or the corpus within StudyWizardry to see words in real context. Our Flashcards feature is perfect for creating “collocation cluster” cards (e.g., “Commit: commit a crime, commit to a goal, commit resources”).

4. Conduct a Rigorous Error Audit: Take one of your old essays and, without looking at any feedback, try to find and correct 10 errors yourself. Then, use a tool like the AI Note Maker to get a second, objective opinion. This actively trains your ability to self-correct, which is crucial for boosting your Grammatical Range and Accuracy score.

Conclusion: The Final Push

Breaking the 6.5 barrier is ultimately a test of your strategic intelligence, not just your English ability. It requires you to shift from a candidate who shows language to one who controls it with precision, logic, and natural expression.

Focus on depth over breadth, precision over complexity, and flow over formula. The difference between a 6.5 and a 7 is small in points but vast in demonstrated skill. By focusing on the nuanced feedback the band descriptors are secretly giving you, you can finally make that leap and achieve the score you truly deserve.
