Understanding the IELTS Writing Band Descriptors: What Do Examiners Really Want?

You finally drop your pen. The 40 minutes are up. You hit the word count, managed to squeeze the word "ubiquitous" somewhere into paragraph three, and you are absolutely certain you answered the prompt. But a few weeks later, the results drop. You are staring at a 6.0. Again.

It is infuriating, honestly. I talk to students all the time who think the examiner just woke up on the wrong side of the bed, or maybe didn't like their handwriting. But the truth is far more boring—and honestly, far more useful. The IELTS grading system isn't some mystical black box where a grumpy British person arbitrarily decides your fate. It is a rigid, publicly available checklist called the band descriptors.

If you haven't read them, you are essentially trying to play a game without knowing the rules. Let's actually break down what the person grading your essay is looking for, without the academic jargon.

The Four Pillars of Your Writing Score

Your final writing grade is just an average of four specific categories. And yes, Task 2 is worth double the points of Task 1, so please, for the love of God, spend more time on it. But the underlying criteria? Exactly the same for both.

Criterion	What It Means in Simple Terms
Task Achievement / Response	Did you answer the actual question, or the one you wished they asked?
Coherence and Cohesion	Can I read this without getting a headache?
Lexical Resource	Are you using words correctly, or just trying to sound smart?
Grammatical Range and Accuracy	How badly are your grammar mistakes messing up your message?

Let's get into the weeds a bit.

1. Task Achievement (for Task 1) and Task Response (for Task 2)

This is the bedrock. If you mess this up, the rest of your essay doesn't matter. It is a brutal reality, but I have seen beautifully written, grammatically flawless essays score a 5.5 simply because the student went completely off-topic.

For Task 1, you are looking at a chart or a diagram. Your job is to describe what is there. Don't give me your personal opinion on why carbon emissions dropped in 1998—just tell me they dropped. You need an overview sentence that captures the main trend, and you have to back up your claims with actual numbers from the image.

Task 2 is a different beast. You are building an argument. If the prompt asks for causes and solutions to traffic congestion, and you spend 200 words complaining about how annoying traffic is without offering a single solution... well, you haven't answered the prompt. You need a clear position. The examiner shouldn't have to play detective to figure out what you actually think.

2. Coherence and Cohesion

This is where a lot of students bleed points without realizing it. Coherence is about logic. Does paragraph B naturally follow paragraph A? Cohesion is the glue—the linking words.

But here is the thing: examiners hate it when you just mechanically insert "Furthermore" and "Moreover" at the start of every single sentence. It feels robotic. It feels like a template. They want to see one clear idea per paragraph. They want your argument to build, not just jump randomly from point to point like a distracted squirrel.

---

3. Lexical Resource (Vocabulary)

I cannot stress this enough: stop trying to memorize lists of "Band 9 vocabulary." It almost always backfires.

Lexical Resource is about precision, not complexity. It is about using words that naturally fit together—what we call collocations. A native speaker says "a steep decline," not "a heavy go-down."

When you try to force a massive, obscure word into a sentence where it doesn't belong, it screams "I memorized this!" to the examiner. A simple word used perfectly will always, always score higher than a complex word used incorrectly. I would rather read "bad weather" than "cataclysmic atmospheric conditions" if the latter makes no sense in context.

---

4. Grammatical Range and Accuracy

Finally, grammar. Range means you aren't just writing "The dog is brown. The dog is big." You are using complex sentences, relative clauses, conditionals. Accuracy is... well, how many mistakes you make.

A Band 5 writer makes enough errors that I have to physically stop and re-read a sentence to understand it. A Band 6 writer makes mistakes, but I still get the point. A Band 7 writer? They are using complex structures and producing a lot of completely error-free sentences. They might slip up here and there—everyone does under time pressure—but they are clearly in control of the language.

---

What Does This Mean for You?

Understanding these four criteria is the first step. The next is to use them to analyze your own writing. Before you submit your next practice essay, ask yourself:

1. Have I fully answered the question? (Task Achievement/Response)
2. Is my essay easy to follow? (Coherence and Cohesion)
3. Have I used a good range of vocabulary correctly? (Lexical Resource)
4. Have I used a mix of sentence structures with few errors? (Grammatical Range and Accuracy)

By thinking like an examiner, you can start to spot your own weaknesses and turn them into strengths.

Linking Words and Cohesive Devices: Your Secret Weapon for a Higher Writing Score

Have you ever written an IELTS essay with solid ideas, only to get a disappointing score for "Coherence and Cohesion"?

You have great ideas. Your grammar is solid. You feel pretty good about the essay you just handed in. But when the score comes back, your "Coherence and Cohesion" mark is dragging everything else down.

It is incredibly frustrating, isn't it? You know your points make sense in your head, but whoever graded it clearly struggled to follow your argument. The essay probably felt clunky, jumping from one idea to the next without any real flow. This lack of smooth transitions is exactly what keeps so many students stuck at a Band 6.0, wondering what they did wrong.

So, how do you actually fix it? How do you bridge the gaps between your ideas so your essay reads like a professional, logical argument instead of a disjointed list? The answer lies in mastering cohesive devices—the secret weapons of high-scoring IELTS essays.

What Are Cohesive Devices (and Why Do They Matter So Much)?

Think of cohesive devices as the road signs in your essay. They tell the reader exactly where you are going. They show how your sentences relate to each other, acting as the glue that holds your paragraphs together.

In the IELTS Writing test, this is officially graded under "Coherence and Cohesion," which makes up a massive 25% of your total score. Without these road signs, your essay reads like a random list of disconnected thoughts. With them, your writing becomes persuasive, structured, and effortless to read.

But here is where things go wrong. A lot of students believe that simply cramming more linking words into an essay will automatically boost their score. That is a dangerous myth, and it is costing you points.

---

The Myth of "More is Better"

It is a classic IELTS trap: memorizing a massive list of linking words and forcing them into the beginning of every single sentence.

"Firstly, pollution is bad. Furthermore, it hurts animals. Moreover, it costs money. In conclusion, we must stop it."

This approach doesn't make you sound advanced. It makes your writing sound robotic and repetitive. Examiners are trained to spot memorized templates instantly. When you overuse linking words, your essay feels heavy and unnatural, which actually lowers your Coherence and Cohesion score. It is like putting a stop sign every ten feet on a highway—it just annoys the driver.

How to Use Cohesive Devices Naturally

To hit a Band 7 or higher, you need to use cohesive devices with precision. It isn't about volume; it is about variety and accuracy. Here is how to do it right.

Cohesion isn't just about words like "however" or "therefore." You can create flow using other techniques, such as pronouns. Instead of repeating a noun, use "this," "these," or "which" to refer back to the previous sentence.

Example: "Electric cars are becoming cheaper. This makes them accessible to more people."

2. Understand the Exact Meaning

Never use a linking word unless you know exactly what relationship it shows.

• Are you adding information? Use in addition or furthermore.

• Are you showing a contrast? Use however or on the other hand.

• Are you giving a result? Use consequently or as a result.

Using "therefore" when you actually mean "however" will completely destroy the logic of your paragraph. I see this all the time, and it is painful to read.

3. Change Up Your Placement

Not every linking word needs to sit at the very beginning of a sentence followed by a comma. Native speakers often bury them in the middle of a sentence to make the writing flow better.

Instead of: "Therefore, the government should raise taxes."Try: "The government should, therefore, raise taxes."

3 Common Mistakes to Avoid

Before you write your next essay, make sure you aren't making these classic errors:

1. The Template Trap: Relying on "Firstly, Secondly, Thirdly" for every single essay. It is boring and shows a limited range of language.

2. Contradictory Links: Using two linking words that fight each other. Writing "Therefore, however..." makes absolutely no sense and will confuse the examiner.

3. The "Brain Dump": Using a linking word just because you feel like you haven't used one in a while, even if the sentence doesn't actually need it.

Your Actionable Checklist for Flawless Cohesion

To ensure your writing is both coherent and cohesive, use this checklist every time you practice:

[ ] Link with Logic, Not Just Labels: Does my argument flow logically even without the linking word? If so, I might not need it.

[ ] Vary My Cohesive Devices: Am I using a range of linking words and other cohesive techniques (like pronouns and synonyms)?

[ ] Check for Natural Flow: Have I read my essay aloud to check if it sounds natural and not mechanical?

[ ] Use Linking Words Accurately: Have I chosen the correct linking word to show the intended relationship between my ideas?

[ ] Avoid Overuse: Have I used linking words only when necessary to guide the reader?

From Clunky to Cohesive: The Path to a Higher Score

Mastering cohesive devices is about quality, not quantity. It’s about understanding the logical connections between your ideas and using linking words as precise tools to make those connections clear to the examiner. By moving beyond memorized lists and focusing on the function and natural application of these devices, you can significantly improve your Coherence and Cohesion score. Of course, knowing the rules is only half the battle. The real skill comes from practice and receiving expert feedback.

If you're ready to take your writing to the next level and learn how to apply these techniques flawlessly, I encourage you to explore Teacher Ivan’s IELTS General Writing course.
