IELTS Listening flow chart completion questions appear in Parts 3 and 4 of the test and require you to follow a sequence of steps or events. In these process questions, you must listen for information that fills gaps in a visual flow chart, often using words directly from the recording or choosing from a box of options. This guide explains what to expect, how to approach the task, and how to avoid common traps.

What Is an IELTS Listening Flow Chart Completion Question?

In an IELTS Listening flow chart completion task, you see a diagram with boxes connected by arrows. The chart shows the stages of a process or a sequence of events. Your job is to complete the missing information in some of the boxes. These questions usually appear in Part 3 (a conversation in an educational setting) or Part 4 (an academic lecture). They test your ability to understand the order of information and to pick out key details.

The flow chart may ask you to write words from the recording in the gaps, or to choose letters from a box of options. The arrows show the direction of the process, and the speaker will use sequencing words such as first, then, once, after that, finally to signal when they move to the next stage. You must follow the arrows and listen for these signposts to keep your place.

What Does an IELTS Listening Flow Chart Look Like?

A flow chart question is not a table or a form; it is a series of boxes linked by arrows. The instructions are in bold at the top. Here is a realistic example based on Part 3 of the test, where two students are discussing a project about recycling plastic.

Write ONE WORD AND/OR A NUMBER for each answer.

Plastic Recycling Process

• Collected plastic is sorted by 1 ________ ↓
• Plastic is washed and then 2 ________ into small pieces ↓
• Pieces are melted at a temperature of 3 ________ °C ↓
• Melted plastic is formed into 4 ________ ↓
• New products are manufactured from these

Notice that the gaps are numbered and follow the arrows. The words around each gap help you predict the type of answer needed. For example, gap 1 comes after "sorted by", so you expect a noun (a method or category). Gap 2 follows "washed and then", so you need a past participle verb. Gap 3 is a number with a degree symbol. Gap 4 is a noun after "formed into".

Step-by-Step Strategy for IELTS Listening Flow Chart Completion

Use this three-stage approach to handle flow chart completion questions confidently.

Before Listening

1. Read the instructions carefully. Check the word limit, such as "ONE WORD AND/OR A NUMBER". If you write more than allowed, your answer is wrong.
2. Study the flow chart. Look at the title and the boxes. Understand the overall process. Follow the arrows to see the order.
3. Predict the answers. For each gap, look at the words before and after it. Decide what type of word is missing: a noun, a verb, an adjective, a number, etc. This helps you listen for the right information.
4. Underline keywords. In the boxes, underline words that are likely to be paraphrased in the recording. For example, "sorted by" might become "separated according to".
5. Think about sequencing language. Remind yourself that the speaker will use words like firstly, next, then, after that, finally to move from one stage to the next.

While Listening

1. Follow the arrows. Keep your eyes on the box you are listening for. As soon as you hear the answer for one gap, move your attention to the next box.
2. Listen for signposts. Sequencing words tell you that the speaker is moving to the next stage. If you hear "Once the plastic is washed, we then...", you know gap 2 is coming.
3. Expect paraphrasing. The words in the flow chart will not be exactly the same as the recording. For example, "melted at a temperature of" might be said as "heated to exactly".
4. Watch out for corrections. Speakers often change their minds. The first thing they say may be wrong. Listen for phrases like "No, actually..." or "I mean..." and take the corrected version as your answer.
5. Write exactly what you hear. If the answer is a word from the recording, do not change its form. If the instructions say "ONE WORD", a hyphenated word like "high-quality" counts as one word. Numbers can be written as figures (e.g., 200) to save time.

After Listening

1. Check your spelling. Misspelt answers score zero. Make sure common words are correct.
2. Review the word limit. Count the words in each answer. If you wrote "a large pellet" but the limit was "ONE WORD", your answer is invalid.
3. Transfer answers carefully. In the paper test, you have 10 minutes to copy your answers to the answer sheet. In the computer test, you have 2 minutes to check. Ensure the question numbers match.
4. Guess if necessary. There is no penalty for wrong answers, so never leave a blank. Write something logical based on your predictions.

Worked Example with Transcript

Here is the transcript for the flow chart above. Two students, Tom and Lisa, are discussing their project.

Tom: Okay, so the first step in recycling plastic is collection. Once it arrives at the plant, the plastic is sorted by colour. That’s because different colours have different properties. Lisa: Right. And then it’s washed to remove any labels or dirt. After washing, it’s ground into small pieces—or I should say shredded, actually. The term is shredded. Tom: Got it. Then those pieces are melted. The machine heats them to 200 degrees Celsius. No, wait, I checked the notes—it’s 220 degrees. Lisa: Are you sure? Tom: Yes, 220. After melting, the plastic is formed into pellets. Those pellets are then sold to manufacturers who make new products.

Answers Explained

1. colour

• The flow chart says "sorted by 1 ________". Tom says "sorted by colour". The paraphrase is minimal here, but "colour" is the exact word. No trap.

2. shredded

• The flow chart says "washed and then 2 ________ into small pieces". Lisa says "ground into small pieces" first, but then corrects herself: "or I should say shredded, actually. The term is shredded." The corrected word is "shredded". "Ground" is a distractor.

3. 220

• The flow chart says "melted at a temperature of 3 ________ °C". Tom first says "200 degrees", then corrects himself: "No, wait... it’s 220 degrees." The answer is 220. The number can be written as a figure.

4. pellets

• The flow chart says "formed into 4 ________". Tom says "formed into pellets". No correction here, and the paraphrase is direct. The word "pellets" fits the one-word limit.

Common Mistakes and Traps

• Ignoring the word limit. If the instruction says "ONE WORD" and you write "small pellets", your answer is wrong, even if "pellets" is correct. Always check the limit.
• Writing the first thing you hear. Speakers often make a false start or mistake and then correct themselves. In the example, "ground" and "200" were both distractors. Listen for the final version.
• Losing your place. If you miss one answer, you might miss the next. Follow the arrows and sequencing words carefully. If you get lost, look ahead at the next box and listen for its keyword.
• Spelling errors. Simple words like "colour" or "pellets" must be spelled correctly. British and American spellings are both accepted, but the spelling must be consistent and correct.
• Not predicting grammar. If the gap follows "into", you know you need a noun. If it follows "is", you might need an adjective or past participle. Predicting helps you catch the answer quickly.
• Ignoring paraphrases. The recording will rarely use the exact words from the flow chart. For example, "sorted by" might be paraphrased as "separated according to". Be ready for synonyms.

How to Practise IELTS Listening Flow Chart Completion

Regular, focused practice is the best way to improve. Here are some exercises you can do:

• Create your own flow charts. Take a process from a textbook or online article (e.g., how chocolate is made) and draw a flow chart with gaps. Then listen to a related recording and try to fill them.
• Transcribe short sections. Find a recording with a clear sequence, such as a lecture on a historical event. Write down the sequencing words and the key nouns and verbs. This trains your ear for signposts.
• Practise with official IELTS materials. Use sample tests that include flow chart completion questions. Time yourself and simulate exam conditions.
• Focus on distractors. Listen to recordings and note any self-corrections. Write down both the distractor and the correct answer to become familiar with this trap.
• Use online listening exercises. Websites with IELTS-style tasks let you practise this question type repeatedly. For structured lessons that target flow chart completion and other listening skills, try IELTS Listening lessons.

Key Takeaways

• Flow chart completion questions appear in Parts 3 and 4 and test your ability to follow a process or sequence.
• Always check the word limit and predict the grammar of the missing word before you listen.
• Follow the arrows and listen for sequencing words like first, then, after that to stay on track.
• Beware of distractors and self-corrections; the first answer you hear may not be the right one.
• Spelling and word count are critical—one extra word or a misspelling makes your answer invalid.
• Practise with real IELTS recordings and focus on paraphrases and signposting language.

Frequently asked questions

What are IELTS Listening flow chart completion questions?

These questions show a flow chart with boxes connected by arrows, representing a process or sequence. You must fill in gaps in some boxes using words from the recording or by choosing letters from a box of options. They appear in Parts 3 and 4 of the IELTS Listening test.

How do I follow a flow chart in IELTS Listening?

Follow the arrows from one box to the next. Listen for sequencing words like 'first', 'then', 'after that', and 'finally' which signal the move to the next stage. Keep your eyes on the current box and move on as soon as you hear the answer.

What is the word limit for flow chart completion questions?

The word limit is given in the instructions, for example 'Write ONE WORD AND/OR A NUMBER for each answer' or 'NO MORE THAN TWO WORDS'. You must follow this limit exactly; writing more words than allowed will make your answer incorrect.

How can I avoid distractors in IELTS Listening flow chart questions?

Speakers often say one thing and then correct themselves. Listen for phrases like 'No, actually...' or 'I mean...' and take the corrected version as your answer. Also, be aware of paraphrasing—the recording will use different words from the flow chart.

Where do flow chart completion questions appear in the IELTS Listening test?

They usually appear in Part 3 or Part 4. Part 3 is a conversation between two or more people in an educational or training context, while Part 4 is an academic lecture by one speaker. Both parts feature processes or sequences that suit flow charts.
