How to Practice for IELTS Writing: Turn the Official Band Descriptors into a Practice Checklist

2026-09-26 · Guides

IELTS Writing Task 2 is weighted twice as much as Task 1; whether you score a 5 or a 7 in Task 1 almost entirely depends on including a clear overview. This article breaks down the official writing band descriptors (May 2023 version) item by item, turning each requirement into specific practice tasks, and provides a structured workflow for self-assessment and rewriting.

IELTS Writing is the section where many students get stuck the longest: reading and listening scores go up, but writing hovers around a 6. Common practice involves memorizing model essays, using templates, and swapping in "advanced words," but the results are often limited. This article takes a different approach: it directly uses the official IELTS Writing Band Descriptors (updated May 2023) to see exactly what is required for each band, and then turns those requirements into actionable practice steps. This article on scoring 8777 in IELTS briefly touched on the boundary between a 6 and a 7; this one goes into more detail, focusing on "how to practice."

Understand the Rules First

Writing takes 60 minutes in total for two essays.
Task 1 requires at least 150 words, and it is recommended to spend no more than 20 minutes. The Academic module involves describing charts, processes, or maps; the General Training module involves writing a letter.
Task 2 requires at least 250 words, and it is recommended to spend no more than 40 minutes on an argumentative essay.
Task 2 is worth twice as much as Task 1 in the Writing score.
Each task is scored on four criteria: Task Response (called Task Achievement for Task 1), Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. All four carry equal weight.

The official descriptors explicitly list several penalty conditions: if the word count is too short, the examiner won't see enough linguistic evidence to award a high score; if the content is irrelevant to the prompt; if it is not written as a coherent essay (e.g., written as a bulleted list); or if there is plagiarism. The lower band descriptors also mention "memorized phrases" and state that "content copied from the prompt is not counted."

Additionally, IELTS in mainland China is now entirely computer-delivered (we verified this in this article). For computer-delivered writing, you type, and the word count is displayed on the screen. You should also practice typing on a computer during your regular preparation.

Task 1: Your Score Depends Almost Entirely on the "Overview"

Taking the Academic module as an example, the differences between bands 5 and 8 for Task Achievement are very clearly outlined in the descriptors:

Band 5: Key features are not fully covered; descriptions of details are largely mechanical recounts; may lack data support.
Band 6: Attempts to write an overview; selects and reports main features appropriately, supported by data.
Band 7: Presents a clear overview, data is appropriately categorized, and main trends or differences are highlighted.
Band 8: Key features are well selected, and their presentation, highlighting, and illustration are very clear.

Comparing these makes it clear: many students score a 5 or 6 in Task 1 not because of poor language, but because they write from the first year's data to the last, and from the first line to the last—this is exactly what the descriptors mean by "mechanical recounts." To reach a 7, you need to do three things: provide an overview, categorize data, and select key data.

Plan the overview before writing. In the first two or three minutes of looking at the graph, ask yourself only one question: If you could only use two sentences to tell someone the most important thing about this graph, what would you say? For example, "Overall, there was an increase, with A growing the fastest," or "The structures of the three countries are completely different." These two sentences are your overview, and it's best to place them in a separate paragraph right after the introduction.
Categorize by features, not by sequence. Group trends that move in the same direction into one paragraph, and compare the highest and lowest values together. Categorize process diagrams by stages, and maps by "additions, removals, and changes."
Data is evidence, not the whole content. One or two supporting numbers for each key feature are enough; you don't need to write down every single number.

The requirements for General Training letters are different: all bullet points must be covered and developed, the purpose of the letter must be clear, and the tone (formal, semi-formal, or informal) must be consistent and appropriate for the context. The most common reason for losing points is missing one of the bullet points in the prompt, or writing a letter to a stranger with the same casual tone as you would use for a friend.

Task 2: Carries the Most Weight and Has the Most Specific Requirements

Task 2 makes up the bulk of the Writing score. Looking at the four criteria one by one, each can be turned into specific practice exercises.

Task Response: Answer the Prompt Fully, Maintain a Clear Position, and Develop Ideas Adequately

The requirement for a 7 is: the main parts of the prompt are adequately addressed; the position is clear and developed; main ideas are extended and supported, but there may be overgeneralization, or the supporting material may lack focus and precision. A 6, on the other hand, means: the main parts are addressed, but some are more fully developed than others; the position is relevant, but the conclusion may be unclear or repetitive; and some ideas are underdeveloped.

Corresponding practice methods:

Deconstruct the prompt. Before writing, circle every question in the prompt. "Discuss both views and give your opinion" requires three things: one side, the other side, and your opinion. "What are the causes of this problem and how can it be solved?" is two questions. Missing any part will prevent you from meeting the band 7 requirement of "adequately addressing the main parts."
Maintain your position throughout the essay. State your position in the introduction, ensure every body paragraph serves this position, and return to it in the conclusion. The most common problem is stating agreement in the introduction, but then shifting to "it has pros and cons" as you write.
Avoid saying "everyone" or "always" when developing ideas. One difference between a 7 and an 8 is the presence of "overgeneralization." Instead of writing "all young people today cannot live without their phones," write about a specific situation and its specific consequences. For every body paragraph, ask yourself: Did I explain "why" for this idea? Did I provide a specific example?

Coherence and Cohesion: Use "Firstly, Moreover" Less

A key phrase in the band 6 descriptor is that the use of cohesive devices may be "mechanical," with over-use, under-use, or inaccuracy. Band 7 requires flexible use of a variety of cohesive devices, including referencing and substitution.

Starting every sentence with Firstly, Moreover, In addition, or Furthermore is a classic example of "mechanical" writing. A more natural approach is to use words like this, these, such a policy, or this trend to refer back to the previous text, or to use synonyms to replace repeated nouns. Additionally, each paragraph should have a clear central idea, and the sentences within the paragraph should progress logically. This is more important than using a high volume of transition words.

Lexical Resource: Accuracy is More Important Than "Advanced" Vocabulary

The requirement for a 7 is: vocabulary is sufficient to show some flexibility and precision; uses some less common words and idiomatic expressions; shows awareness of style and collocation, but may still produce some inappropriate word choices. Band 8 requires skillful use of less common vocabulary at appropriate times, with only occasional inaccuracies in word choice or collocation.

The key phrases here are "collocation" and "appropriate times." An "advanced word" used with the wrong collocation will show the examiner that you don't truly master it. The practice method is to accumulate collocations rather than isolated words: when you encounter a good expression, memorize it along with the words before and after it, such as pose a threat to, have a profound impact on, or address the issue.

Grammatical Range and Accuracy: First, Reduce Errors

The requirement for a 7 is: uses a variety of complex structures with some flexibility and accuracy; error-free sentences are frequent. Band 8 requires the majority of sentences to be error-free.

In other words, the main grammatical change from a 6 to a 7, and then to an 8, is not writing more complex sentences, but making fewer and fewer errors. Most students' grammatical errors are concentrated in a few fixed areas: articles, singular/plural forms, subject-verb agreement, tenses, and run-on sentences (joining two complete sentences with a comma). Compile a list of your most frequent errors and check your essay against this list every time you finish writing.

A Practical Practice Routine You Can Follow

Write under timed conditions. Spend 20 minutes on Task 1 and 40 minutes on Task 2, typing on a computer.
Self-assess using the four criteria. With the band descriptors in hand, ask yourself for each criterion: Did I address every part of the prompt? Is there an overview or a clear position? Is the cohesion mechanical? Are there any collocation errors? Are there many error-free sentences?
Rewrite the same essay. After getting feedback from a teacher or yourself, rewrite the same prompt instead of immediately moving on to a new one. The first draft exposes problems; the second draft is where the actual practice happens.
Update your error list. Record any recurring grammatical errors from each essay onto your list.
Have a teacher grade your work using the four criteria regularly. It is hard to spot your own blind spots when grading your own writing.

A realistic volume is: 2 Task 2 essays and 2 Task 1 essays per week, rewriting each one. Sticking to this for a month or two is much more effective than writing one essay every day but never looking back.

On Model Essays and Templates

You can read model essays, but the goal is to learn how they organize arguments and develop examples, not to memorize them. The lower band descriptors explicitly mention "memorized phrases and templates"; if you memorize entire introductory and concluding paragraphs, the examiner will spot them immediately. Moreover, they often don't fit the specific prompt closely, which can actually hurt your Task Response score.

What is truly worth "memorizing" are the cohesive devices and collocations you have already mastered, as well as specific examples you can develop for common topics (education, technology, environment, urban life, work).

Final Thoughts

The IELTS Writing band descriptors are public and very specific. Instead of guessing what the examiner wants, treat the descriptors as your practice checklist: practice overviews and categorization for Task 1, and prompt deconstruction, idea development, and error reduction for Task 2. Self-assess and rewrite every essay against the criteria, and your score will gradually improve.

If you are unsure which criterion is holding your essay back, you can start with a diagnostic test. Our teachers will grade your essay step-by-step according to the official four criteria and provide revision suggestions.
