How to Tackle Diagram Questions in IELTS Listening – My Expert Guide

I’m an IELTS coach, and I’ve been helping students for over 14 years. I have assisted thousands of students who get stuck on various types of questions in the IELTS Listening test. Test takers are often bewildered by one kind of question: diagram labeling. It’s relatively easy for some students and much more difficult for others, who get lost matching the blanks — tons of blanks — with what they hear in the audio.

In this comprehensive guide, I’m going to take you through everything you need to know about diagram-based questions on the IELTS Listening test. You’ll walk away with a solid plan for facing them calmly and raising your score in the process. Let’s get started!

What Are IELTS Listening Diagram Questions?

Diagrams are one of the question types you will see in Section 2 of the IELTS Listening test. For these questions, you will see a partial diagram showing its:

A machine, device, or tool (e.g., a washing machine, vacuum cleaner, or microscope)
A process or system (e.g., water purification, recycling, or the digestive system)
A map or layout (e.g., a building, a garden, or a new park plan)
Any object with parts labeled

Your task is to listen to the audio carefully and fill in the missing parts of the diagram. The missing labels could be nouns (names of parts), numbers (measurements, time, or quantity), or adjectives (descriptive words).

Since these questions are direct and highly scoring, they are a great opportunity to increase your IELTS Listening band score—but only if you follow the right strategy!

Now, I will solve the question with the diagram using the guide.

Step 1: Take a Long, Hard Look at the Diagram Before the Audio Plays

You will have 30 seconds to glance at the diagram before the recording starts. This is a crucial step! Students who don’t use this time then find it hard to follow the description in the audio. Here’s what you should do:

What kind of a diagram is it – a machine, a building layout, a system, or a process? Understanding the context of the diagram helps you know what to expect when you listen.
Examine the labeled components – Some components will already have labels. These may provide you clues about the missing labels.
Look at the blanks – Make an educated guess of the kind of information it is missing. Will it be a noun (as in a part of the machine), a number (measurement), or a direction word (left, right, above, below)?
Arrows and labels — Again, arrows often indicate a direction or step in a sequence. If there are arrows on the diagram, go with the flow and see how the speaker will explain it.

Example: If the diagram is for a vacuum cleaner, the missing words could be the names of the vacuum cleaner parts, i.e., “motor”, “filter,” or “hose”.

Step 2: Make a Prediction of the Possible Answers

When you feel comfortable with the diagram, predict possible answers before the audio begins. This is not to say it has to be 100 percent right, but this step will at least get your brain ready for the right kind of information as you listen.

Consider the grammar – Will the missing word probably be a noun, adjective, number, or measurement?
Think logically – If the diagram is for a kitchen layout, the missing words are likely to be “fridge”, “sink”, “cupboard,” or “oven”.
Be careful of prepositions – Words such as above, below, next to, beside, opposite, in front of will help you find the right answer.

Pro Tip: The label words and the title of the diagram are always hints for what information is missing. Use them for logical predictions!

Step 3: Link Each Question with the Order in the Audio

A mistake that students often commit is skipping starred messages in the diagram. This causes confusion and wrong answers. Rather, follow the order of the audio, because the speaker will explain the diagram in the order.

Here’s what you should do:

Blank 1 reverts back to its original state, and you simply focus on finding that answer.
Head to blank 2, and when you hear the answer, go through the same process.
If you miss an answer, don’t panic — concentrate on the next one.

Pro Tip: The layout of the IELTS Listening test is logical, which means the speaker will not suddenly jump to different parts of the diagram. They will walk through the process step by step, so have faith in the order of the questions.

Step 4: Pay Attention to Synonyms and Paraphrasing

The tricky thing about IELTS Listening is that what you hear in the audio will not always be the same as what you read in the diagram. The examiners love to test whether you can find synonyms and paraphrase.

Example 1: If the answer is “ventilation system,” the speaker could say “airflow control” or “exhaust system.”
Example 2: The speaker could say “compartment” or “section for keeping items” if the missing word is “storage area.”

Tip: Expand your vocabulary and get used to identifying synonyms in context by listening to English podcasts, TED Talks, or IELTS practice tests.

Step 5: Be Smart About Word Limit Guidelines

Read through the instructions before writing your answer. Questions in IELTS Listening always have word limits. for example:

One word only
Rewrite it in two words and/or a number
Not exceeding three words and/or a number

Important: Writing over the number of words allowed will cause your answer to be marked incorrect, even though it is correct!

Example:

Correct: Filter (if the instruction says “One word only”)
Wrong: The filter (because “the” makes it two words)

So, before writing your final answer, check the word limit!

Common Mistakes to Avoid

Not reviewing the diagram correctly ahead of the audio starting – Always spend 30 seconds to visually take in the diagram before listening.
Skipping ahead or jumping around – Stay on track by following the order of the numbering system.
Not doing paraphrasing – Less likely to ignore synonyms — the audio will definitely not use the words you are expecting.
Crossing the word limit – It’s a common misconception that writing the correct answer will earn marks even if it doesn’t adhere to the word instructions; however, that’s false.
