How To Write an
IELTS Line Graph Essay

Here is the 5 steps process I recommend for planning and writing IELTS line graph essays:

I’m going to take you through the whole process step-by-step as we work on a practice question.

Many students are reluctant to spend time on steps 1 and 2 as they want to spend as much of the 20 minutes allowed for the essay as possible actually writing it. However, it is essential that you do them as they are the key to writing a high-scoring IELTS line graph essay.

Before we begin, here’s a model essay structure that you can use as a guideline for all IELTS Academic Task 1 questions.

Ideally, your essay should have 4 paragraphs:

Now that we have all these tools we need, we’re ready to begin planning and writing our IELTS line graph essay.

Here’s our practice question:

Step 1 – Analyse the question

The format of every Academic Task 1 question is the same. Here is our practice question again with the words that will be included in all questions highlighted .

Every question consists of:

Sentence 2 tells you what you have to do.

You must do 3 things:

All three tasks refer to the ‘main features’ of the graphic. You do not have to write about everything. Just pick out 2 or 3 key features and you’ll have plenty to write about.

Step 2 – Identify the Main Features

The graphic in IELTS line graph questions should not be difficult to interpret. Each question has been created to test your language skills, not your mathematics ability.

All you are looking for are the main features. These will usually be the easiest things to spot. There will be lots of information in the graphic to help you identify them.

Here are some useful questions to ask?

(I give more detail on how to use these questions, plus downloadable checklists for identifying the main features of all 7 different types of IELTS Academic Writing Task 1 questions, in the lesson on How To Understand & Analyse Task 1 Questions.)

So, what main features stand out in our practice graphic?

Here's our IELTS line graph again.

The timeline will give you the biggest clues as to the most significant trends. Look for general trends.

There are 2 main features/trends in this line graph:

The general trends you select will be the starting point for your essay. You will then go on to add more detail. However, with just 20 minutes allowed for Task 1, and a requirement of only 150 words, you won't be able to include many details.

We’re now ready to begin writing our essay. Here’s a reminder of the 4 part structure we’re going to use.

Step 3 – Write an Introduction 

In the introduction, you should simply paraphrase the question, that is, say the same thing in a different way. You can do this by using synonyms and changing the sentence structure. For example:

This is all you need to do for the introduction.

---

Step 4 – Write an Overview (Paragraph 2)

In the second paragraph, you should report the main features you can see in the graph, giving only general information. The detail comes later in the essay. You should also make any clear comparisons you spot.

This is where we write about the general trends. Here are the ones we picked out above.

Now form these ideas into two or three sentences with a total of around 40 words. State the information simply using synonyms where possible. No elaborate vocabulary or grammar structures are required, just the appropriate words and correct verb tenses.

For example:

---

Step 5 – Write the 1st Detail Paragraph

Paragraphs 3 and 4 of your IELTS line graph essay are where you include more detailed information about the data in the graphic. In paragraph 3, you should give evidence to support your first key feature. Don’t forget to make comparisons when relevant.

Here is our first main feature again:

And this is an example of what you could write:

---

Step 6 – Write the 2nd Detail Paragraph

For the fourth and final paragraph, you do the same thing for your second key feature. 

Here’s an example of what you could write:

Here are the four paragraphs brought together to create our finished essay.

Finished IELTS Line Graph Essay

This sample IELTS line graph essay is well over the minimum word limit so you can see that you don’t have space to include very much detail at all. That’s why it is essential to select just a couple of main features to write about.

Now use what you’ve learnt in this lesson to practice answering other IELTS line graph questions. Start slowly at first and keep practicing until you can plan and write a complete essay in around 20 minutes.
