Can you use words such as don't, can't, won't and it's in IELTS Writing?
The safest approach is to use full forms in IELTS Writing, particularly when you are aiming for a formal or semi-formal academic style.
For example:
don't → do not
can't → cannot
won't → will not
it's → it is
doesn't → does not
Why should you avoid contractions?
IELTS Writing requires you to choose an appropriate style and register for the task.
Using full forms can help your writing maintain a formal or neutral tone.
Compare:
Informal: People don't always have enough time to exercise.
More formal: People do not always have enough time to exercise.
The second version is generally more appropriate for an IELTS essay.
Will using a contraction automatically lower my IELTS score?
You should not think of one contraction as an automatic score penalty.
IELTS Writing is assessed across four criteria, including Task Response, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy.
However, using informal language where a more formal style is appropriate can affect how appropriately you communicate your ideas.
Therefore, developing the habit of using full forms is a simple way to maintain an appropriate tone.
What about "it's"?
Be particularly careful with it's.
It can mean:
it is
or
it has
For example:
It's important to consider both sides.
can become:
It is important to consider both sides.
Do not confuse it with its, which is a possessive form.
The company changed its policy.
What about IELTS General Training Writing?
The appropriate style depends on the task.
In General Training Writing Task 1, you may be asked to write a letter. The required style can vary depending on the relationship with the recipient and the purpose of the letter.
For example, a personal letter can be less formal than a letter to an organisation.
Task 2 requires a semi-formal/neutral discursive essay, so full forms are generally the safer choice.
Should I avoid all informal language?
Not necessarily. The goal is not to make every sentence sound unnecessarily complicated. You should aim for language that is:
appropriate
clear
accurate
natural
relevant to the task
For example, replacing every simple word with a complicated synonym is not a good strategy.
Examples to remember
Contraction | Full form |
don't | do not |
can't | cannot |
won't | will not |
isn't | is not |
aren't | are not |
doesn't | does not |
didn't | did not |
shouldn't | should not |
couldn't | could not |
wouldn't | would not |
Final takeaway
For IELTS Writing, especially Task 2, make full forms your default.
You do not need to make your writing unnecessarily complicated. Focus on answering the question fully, organising your ideas clearly and using accurate, appropriate language.
When in doubt, choose the full form.
