As an IELTS instructor with over 20 years of experience, I often encounter students who are unsure about the correct formatting of numbers in their IELTS writing. One common query is whether to use a comma (,) or a period (.) as a thousands separator. This article will clarify the correct usage and provide you with the knowledge to present numbers accurately in your IELTS writing.
Understanding Number Formatting in IELTS Writing
While both comma (,) and period (.) are used as thousands separators in different regions, IELTS follows the conventions of British English. Therefore, the correct format is to use a comma (,) as the thousands separator and a period (.) as the decimal separator.
Correct: 1,000
Incorrect: 1.000
Example:
“The population of the city has grown to over 1,500,000.”
Number Format Example
Consistency is Key
Maintaining consistency in number formatting is crucial for clarity and to avoid confusing the examiner. If you choose to write a number numerically, stick to the correct comma format throughout your writing.
When to Write Numbers as Words
While using numerals is generally acceptable in IELTS writing, there are instances where writing numbers as words is more appropriate. For example:
- At the beginning of a sentence: “Two thousand and twenty-three marked a significant year for…”
- For small numbers: “There were only five participants in the study.”
- For approximations: “Approximately one hundred people attended the event.”
Applying Number Formatting in IELTS Writing Tasks
Let’s consider how to apply this knowledge in the IELTS Writing tasks:
Task 1 (Academic): When describing data in graphs, charts, or tables, using the correct comma format for larger numbers ensures clarity and precision.
Task 2 (Academic & General Training): Whether you’re presenting an argument or discussing an issue, accurately formatted numbers enhance the overall clarity and credibility of your writing.
Tips for Success
- Practice consistently: Familiarize yourself with the correct comma format by practicing writing essays and reports using accurate number formatting.
- Proofread carefully: Before submitting your writing, double-check all numbers to ensure they are formatted correctly.
Conclusion
Mastering the correct use of commas as thousands separators in your IELTS writing might seem like a minor detail, but it contributes significantly to the clarity, accuracy, and overall impression of your work. Remember to practice consistently, apply this knowledge diligently, and proofread carefully to achieve your desired IELTS score.
