IELTS Writing Band Descriptors: A Deep Dive for a 7.0+ Score
Stop Guessing. Start Scoring. A Programmer's Guide to Deconstructing the IELTS Marking Criteria.
If you're preparing for the IELTS exam, you've likely stared at the official Writing Band Descriptors PDF. You've probably felt that familiar sense of confusion. It's dense, abstract, and reads more like a legal document than a helpful guide. After reading a hundred student-written "experience" articles, you're still left guessing what an examiner really wants.

The IELTS Band Descriptors don't have to be confusing
But what if I told you the Band Descriptors aren't a mystical piece of art appreciation? What if they are a set of clear, logical rules, like the compiling rules for a piece of code?
As a programmer and a father who has navigated this high-stakes journey, I've learned to see the IELTS marking criteria for what they truly are. Your essay is your code. The examiner is the compiler. If your code follows the rules, it will compile successfully and earn a high score. It's that systematic. And if you're ready to check your writing against these rules, our AI-powered IELTS Writing Checker can analyze your essays in seconds.
In this guide, I will use a programmer's mindset to completely decompile the official rules for you. By the end, you will no longer be guessing. You will be able to analyze your own writing with the precision of an examiner and build a clear path to a 7.0+ score.
The Four Pillars: The System Architecture of a Band 7+ Essay

Collaborate with the right rubric and every Band 7+ essay stands strong
Think of a Band 7+ essay as a well-constructed building. It stands tall and impressive because it's supported by four strong, balanced pillars. If any one of these pillars is weak, the entire structure is compromised. These are the four criteria an examiner uses to score your writing:
- Task Achievement (TA) - For Task 1 (which requires a very different approach, as we detail in our Ultimate Guide to the IELTS Writing Task 1 Checker) / Task Response (TR) - For Task 2
- Coherence and Cohesion (CC)
- Lexical Resource (LR)
- Grammatical Range and Accuracy (GRA)
Let's break down each pillar and transform the abstract language of the descriptors into concrete, actionable steps.
Pillar 1: Task Achievement (TA/TR) – Answering the EXACT Question Asked
💡 Pro Tip: Before diving into task achievement, make sure your essay is free from common grammar mistakes that silently lower your score. Even perfect task response won't save you from grammatical errors.

Task Achievement: Answer every part of the question precisely
Think of TA/TR as the project requirements document. If the client asks for a blue button, but you deliver a beautiful red one, you've failed the project, no matter how well-coded that red button is.
The Crucial Difference: Band 6 vs. Band 7+
| Band 6 (Adequate) | Band 7+ (Good) |
|---|---|
| Addresses the prompt, but some parts may be less covered than others. | Addresses all parts of the prompt fully and sufficiently. |
| Presents a position, but it may not be clear or consistent. | Presents a clear and well-developed position that is consistent throughout. |
Actionable Steps to Secure a 7.0+ in TA/TR:
1. The "Question Deconstruction" Method
Before writing, physically break the prompt down into its micro-questions. A prompt like "Discuss both views and give your opinion" contains three distinct tasks: discuss view A, discuss view B, and clearly state your own opinion. Create a checklist and ensure your essay ticks every box.
2. The "Keyword Synonym Map"
Identify the core keywords in the prompt (e.g., "technology," "communication," "society"). On your draft paper, brainstorm 3-5 synonyms or related phrases for each. This ensures you are consistently addressing the topic without sounding repetitive.
💡 Pro Tip: Unsure if your essay fully addresses the prompt? It's a common blind spot. Our AI Writing Checker's 'Task Achievement' module can analyze your response against the question to identify any gaps.
Pillar 2: Coherence & Cohesion (CC) – The Logic That Guides Your Reader

Coherence and Cohesion: Your essay's GPS system
If your essay is a journey, Coherence and Cohesion is your GPS. Coherence is the overall route—is it logical? Does it lead to the destination? Cohesion is the turn-by-turn navigation—are the street signs (linking words) clear and easy to follow?
The Crucial Difference: Band 6 vs. Band 7+
| Band 6 (Adequate) | Band 7+ (Good) |
|---|---|
| Information is arranged, but the progression may feel mechanical or unclear. | There is a clear and logical progression of ideas throughout the essay. |
| Uses linking words, but may overuse them or use them inappropriately. | Uses a flexible and accurate range of cohesive devices and discourse markers. |
Actionable Steps to Secure a 7.0+ in CC:
1. The "One-Sentence Summary" Technique
Before you write each body paragraph, write a single sentence that summarizes its main point. This sentence is your paragraph's north star, ensuring everything within it serves a single, clear purpose.
2. Build a "Linking Word Toolkit"
Don't just rely on "Firstly, Secondly, In conclusion." Group linking words by their function (e.g.,Contrast: However, Nevertheless, On the other hand; Cause & Effect: Consequently, As a result, Therefore). This allows you to choose the right tool for the job.
💡 Pro Tip: Wondering if your paragraphs flow logically? Our AI Writing Checker can analyze your essay's structure and the effectiveness of your linking words.
Pillar 3 & 4: LR & GRA – Upgrading Your "Code Quality"

Lexical Resource and Grammar: Your essay's code quality
I'm grouping Lexical Resource (LR) and Grammatical Range and Accuracy (GRA) together because they represent the quality of your "code" itself. LR asks, "Are you using a rich library of variables and functions?" GRA asks, "Is your code bug-free and well-structured?"
The Crucial Difference: Band 6 vs. Band 7+
| Band 6 (Adequate) | Band 7+ (Good) |
|---|---|
| Uses an adequate range of vocabulary for the task. | Uses a sufficient range of less common and idiomatic vocabulary with awareness of style and collocation. |
| Makes some errors in grammar and punctuation, but they don't impede communication. | Produces frequent error-free sentences and uses a variety of complex structures naturally and appropriately. But what are the most common errors that secretly lower your score? Understanding these pitfalls is crucial. |
Actionable Steps to Secure a 7.0+ in LR & GRA:
1. The "Vocabulary Upgrade" Drill
Take one of your old essays. Identify 10 common words (e.g., good, bad, important, many) and use a thesaurus or academic word lists to find more precise, higher-level replacements (e.g.,beneficial, detrimental, crucial, a multitude of).
2. The "Sentence Fusion" Practice
Find a paragraph in your writing that consists only of simple sentences. Challenge yourself to combine two or three of them into a single, elegant complex sentence using subordinate clauses, relative clauses, or participial phrases.

See It In Action: How Our AI Analyzes an Essay Like an Examiner

AI-powered analysis provides instant examiner-level feedback
Theory is great, but let's see how it works in practice. While this example shows a single sentence, our deep dive into full Band 9 sample essays reveals how these principles work together across an entire essay. For now, consider this Band 6.5 sample sentence:
"In conclusion, I think using public transport is a good idea because it can solve many problems like traffic jams and pollution."
Here's how an examiner (and our AI) deconstructs it:
- ✅ TA/TR: The position is clear.
- ✅ CC: "In conclusion" is an appropriate signpost.
- ⚠️ LR: The vocabulary is very basic and common (good, many problems). This is a key limiting factor.
- ⚠️ GRA: It's a single, grammatically correct complex sentence, but lacks range.
Now, imagine doing this complex analysis for every sentence in your essay, automatically, in under 10 seconds. Here's a glimpse of how our AI would analyze and suggest improvements:
AI Analysis Results:
✅ Grammar Check:
No errors found.
📝 Vocabulary Suggestions:
- • good idea → a viable solution or a beneficial approach
- • solve many problems → address multiple issues simultaneously
- • like traffic jams and pollution → such as urban congestion and environmental degradation
🎯 Rewritten Sentence (Band 7.5+):
"In conclusion, I firmly believe that promoting public transport is a viable solution, as it can simultaneously address critical urban issues such as traffic congestion and environmental degradation."
This single example shows the leap from a 6.5 to a 7.5 level. It is this kind of precise, targeted improvement that makes all the difference.
