Take careful notice of the following sentence. “Technology is viewed as evil by many individuals but it has done good to education.” The ideas and vocabulary are fine. However, there are two errors in this sentence: punctuation errors. This is why punctuation in IELTS Writing is very important. One mistake will result in losing marks.
Punctuation is not just for decorative purposes. It is an important part of your grammar, and it will be tested in the exam. Candidates normally allow themselves weeks to prepare their vocabulary but almost zero time for punctuation. That is a mistake we correct early at Tiju’s Academy, the best IELTS coaching centre in Kerala, because it is one of the quickest fixes available to a student stuck at band 6.5.
The guide discusses what you need to know, the mistakes examiners make, and an exercise for fixing those mistakes at the end.
Does Punctuation Impact Your IELTS Writing Band?
Yes, it does, and very much. Punctuation is in Grammatical Range and Accuracy IELTS, which accounts for 25 percent of the IELTS Writing test band. It must have numerous sentences which are grammatically correct for band 7. The sentence that has a punctuation error cannot be said to be grammatically correct even though the content of the sentence is very good.
Now let us understand how it works practically:
- A missing comma after “In recent years” is a small slip. Most examiners will let it pass.
- A comma splice error is a serious one. It breaks the sentence and removes it from your error-free count.
- A run-on sentence IELTS Writing candidates often produce, with no punctuation at all between two ideas, looks careless and confuses the reader.
There is a second effect too. If the punctuation is incorrect, then the examiner will have to reread the sentence because this makes things difficult for him. It also influences the overall impression of your coherence and cohesion, although punctuation is not assessed in that category.
At Tiju’s Academy we open every batch with a band descriptor breakdown session. Students see exactly what the examiner ticks and what they ignore. Many candidates are surprised to learn how much punctuation is costing them.
Task 1 and Task 2 have different problems
IELTS Writing Task 1 punctuation issues usually involve numbers, dates, decades, and lists. They write “1990’s” rather than “1990s” and miss out on the commas.
Punctuation problems in IELTS Writing Task 2 are usually connected with linking words and overly long sentences. The words “however,” “therefore,” and “moreover” lead to more mistakes in the essay.
Finally, something else to know. In IELTS paper-based test, messy handwriting may make it impossible to notice commas and full stops. In a computer-delivered test, typing speed is a factor, and usage of commas will increase.
The Basic Punctuation Marks You Need
You only need seven marks for IELTS Writing. Learn these well and ignore the rest.
| Mark | What it does | IELTS example |
| Full stop (.) | Ends a complete sentence | Pollution is rising in major cities. |
| Comma (,) | Separates parts of a sentence | In recent years, costs have increased. |
| Semicolon (;) | Joins two complete, related sentences | Buses are cheap; trains are faster. |
| Colon (:) | Introduces a list or explanation | There are three causes: cost, distance, and time. |
| Apostrophe (‘) | Shows possession or contraction | The student’s essay was excellent. |
| Capital letter | Starts sentences and proper nouns | India, Monday, English, March |
| Hyphen (-) | Joins two words into one idea | a well-known problem, long-term effects |
A few notes on each.
The full stop is your best friend. Most students underuse it. They believe long sentences look advanced. They don’t have to. What band 7 needs is not long sentences but proper ones. In case of doubt, divide the sentence into two.
It creates the most problems for candidates, which is why it will have its own section below.
The colon shows what comes next. It comes before the list or the explanation of what was just stated.
The hyphen combines words that form a describing term before a noun. You should write “a well-paid job” and “short-term benefits.” Do not scatter hyphens randomly.
Marks you should avoid in IELTS
Some punctuation simply does not belong in a formal academic essay. Keep these out of Task 2 and Academic Task 1:
- Exclamation marks. They sound emotional and informal.
- Question marks in body paragraphs. Rhetorical questions weaken your argument.
- Dashes used casually instead of commas.
- Quotation marks around ordinary words for emphasis.
- Ellipsis dots. They suggest you ran out of ideas.
- Brackets. They usually mean the information should have been in the sentence properly.
Our Band 7+ writing templates are built without any of these, so students who use them never fall into the trap in the first place.
Comma Rules in English Writing That Matter for IELTS
A comma separates ideas in a sentence. Do Commas Matter in IELTS Writing? They matter more than any other mark, because comma errors are the most common of all IELTS grammar mistakes in Task 2.
There are only six comma rules you need. Practice these and you will cope with all sentences that you can possibly write.
- Comma after an introductory phrase
If a sentence is introduced with a phrase, follow it with a comma.
- Over the past few years, many people have been working from home. As a result, traffic in city centres has reduced. Although the policy is expensive, it has clear benefits.
This comma after an introductory phrase is an IELTS rule that is easy and safe. Use it often.
- Comma in front of conjunction connecting two independent clauses
A comma should precede and, but, so, or, for, nor, and yet when both parts of the sentence can stand independently. They are known as the coordinating conjunctions, also referred to as FANBOYS.
- Prices have increased, but the number of students hasn’t reduced.
- The town constructed new roads, so there was less traffic.
If the latter part is an incomplete sentence, do away with the comma. This means you write “He worked hard and scored in the examination” without a comma.
- No comma before because, although, while or since if the clause is in the second position
This is the comma before, because IELTS question we get asked constantly. The answer is short. No comma.
- Correct: He failed because he did not revise.
- Wrong: He failed, because he did not revise.
However, if the sentence is inverted and the clause comes first, then the comma is required.
- Although he revised, he failed the test.
- While cities grow rapidly, rural regions continue to shrink.
- Commas in a list of items
Commas are used separate three or more items in a list.
- The government should invest in education, health care and transport.
Do you need an Oxford comma for IELTS Writing? This is the comma before “and” when using a list. Both styles are acceptable in IELTS. Choose whichever one you prefer, but be consistent throughout the entire essay.
- Commas before/after non-defining relative clauses
If the additional information can be omitted from the sentence without altering its meaning, then use commas.
- Delhi, which is the capital of India, has a lot of air pollution.
However, if the information is integral to the meaning of the sentence, use no commas.
- Students who study everyday perform better than those who don’t.
- How to punctuate linking words in IELTS
Most band 6.5 IELTS essays are penalized here. Transition words such as “however,” “therefore,” “moreover,” “furthermore,” and “nevertheless” are not conjunctions and cannot be used to connect two sentences using a comma.
The however-comma rule IELTS Writing students need is simple:
- However, this view is questionable. (start of a new sentence, comma after)
- Costs are rising; however, families are coping. (semicolon before, comma after)
Wrong: Costs are rising, however families are coping.
It is true of, therefore, moreover, in addition, for example, and as a result.
The comma splice, and how to correct it
The use of a comma to connect two complete sentences is referred to as a comma splice. The comma splice error is the most common punctuation mistake made in IELTS essays.
Wrong: The number of students increased, the number of teachers decreased.
There are three correct fixes:
- Full stop: The number of students increased. The number of teachers fell.
- Semicolon: The number of students increased; the number of teachers decreased.
- Comma followed by conjunction: The number of students increased, but the number of teachers decreased.
Do this to test it. Conceal the comma and check whether both parts make sense independently. In that case, only a comma is not sufficient.
The students enrolled in our 250in60 writing correction course are informed about all their comma splices, including the explanations, not just the highlights.
When to Use a Semicolon
Use a semicolon in a sentence when both parts can function independently, but they are strongly related. This is the entire rule. When either part is incomplete, use a comma.
Semicolon usage rules for IELTS come down to two situations.
Joining two related sentences
- Public transport is affordable; it is also better for the environment.
- Online learning saves time; it does not suit every student.
Look at the same idea written three ways:
- Two sentences: Buses are cheap. Trains are faster.
- With a conjunction: Buses are cheap, but trains are faster.
- With a semicolon: Buses are cheap; trains are faster.
All three are correct. The semicolon shows the examiner you can control sentence structure.
Semicolon with linking words
- Costs are rising; therefore, families are cutting back.
- The plan sounds simple; however, it is expensive to run.
Semicolon vs colon IELTS candidates confuse
Here is the quick test:
- A colon introduces or explains. There are two reasons: cost and time.
- A semicolon balances two equal ideas. Cost is a problem; time is another.
How many semicolons should you use?
You can put in one or two semicolons in an essay; that should be sufficient. More than five or six makes it seem artificial, and the examiner takes note of it. You should only use it where it fits best.
This is what we will be discussing in our “vocabulary and grammar improvement lessons,” and students practice it as part of their daily exercises.
Apostrophe Rules in English
An apostrophe can serve one of two purposes: show ownership or show a contraction. The apostrophe will not be used to make a word plural. This is a mistake many students make in their writing.
Possessive apostrophe vs contraction
- Possession shows that something belongs to someone.
- Singular noun: the student’s essay
- Plural noun ending in s: the students’ essays
- Irregular plural: children’s education, women’s rights
Contraction shows missing letters.
- “do not” become “don’t”
- “it is” becomes “its”
- “they are” becomes “they’re”
Can I use contractions in IELTS Writing?
In Task 2 and Academic Task 1, avoid them. A formal academic tone means writing “do not” instead of “don’t.” In general training letter writing to a friend, contractions are fine and even natural. In speaking, use them freely because they make you sound fluent.
Its vs it’s
This is the mistake examiners flag most often.
- “its” shows possession. The company increased its profits.
- “it’s” means “it is.” It’s clear that costs are rising.
If you can replace it with “it is,” use the apostrophe. If not, do not.
Never use apostrophes for plurals
Correct: The chart shows data from the 1990s.
Wrong: The chart shows data from the 1990’s.
Correct: Two universities closed last year.
Wrong: Two university’s closed last year.
This matters in IELTS Writing Task 1 punctuation because decades and years appear in almost every chart description.
Whose vs who’s
Whose shows possession. Students whose parents attended university. “Who’s” means “who is.” Keep them separate.
Capital Letters Rules IELTS Candidates Forget
Capital letters go at the start of every sentence and on every proper noun. That includes:
- Countries and cities: India, Kerala, London
- Languages and nationalities: English, Malayalam, Japanese
- Days and months: Monday, March
- Names of organisations: the World Health Organization
- Titles and specific courses: Doctor Sharma, Bachelor of Science
Do not capitalize ordinary nouns for emphasis.
“The Government should improve Education” is wrong.
Instead write “The government should improve education.”
It is small, but it pops up in every first essay that gets marked during our Base Check, our entry assessment process wherein a trainer determines which mistakes the student makes.
Tips to Use Punctuation Correctly in Your IELTS Writing Task
The best way to address problems with punctuation is through short sentences and working on one error at a time. This is how we teach punctuation at Tiju’s Academy, the best IELTS training centre in Kerala.
- Write short first, then combine. Most punctuation errors come from sentences that grew too long. Write two clean sentences, then decide whether to join them.
- Check every however. If it begins the sentence, put a comma after it. But if it is placed between two full sentences, put a semicolon before it and a comma after it. Don’t use only the comma.
- Perform the standalone test before every comma. If the two can be full sentences on their own, then you have to use a period, semicolon, or conjunction.
- Read the sentence in your head. Natural pauses usually show where commas belong. This works well for introductory phrases.
- Do a punctuation-only proofread. Spend two minutes at the end checking punctuation and nothing else. Looking for everything at once catches almost nothing.
- Keep an error log. Two columns: what you wrote and what is correct. Most students repeat three or four errors. Once written down, they disappear quickly. Our progress tracking system builds this log automatically after each submitted essay.
Our Blank2Brilliant technique helps students generate essay ideas fast, which leaves more time at the end for self-editing. Students who plan well finish with five minutes spare, and that is when punctuation gets fixed. Our time management strategies sessions build that habit from Base camp, the five-day orientation that starts every course.
Common Punctuation Mistakes in IELTS
These are the errors our trainers mark most often. Learn to spot them in your own writing.
| Wrong | Right | Why |
| Costs are rising, however people cope. | Costs are rising; however, people cope. | However is not a conjunction |
| In conclusion governments should act. | In conclusion, governments should act. | Comma after introductory phrase |
| He failed, because he did not study. | He failed because he did not study. | No comma before because here |
| The 1990’s saw rapid growth. | The 1990s saw rapid growth. | No apostrophe in plurals |
| Its clear that pollution is rising. | It’s clear that pollution is rising. | It’s means it is |
| The Government must improve Health care. | The government must improve health care. | No capitals on ordinary nouns |
| Students increased, teachers decreased. | Students increased, but teachers decreased. | Comma splice |
| Don’t ignore this problem. | Do not ignore this problem. | Avoid contractions in Task 2 |
| There are three causes, cost, time and distance. | There are three causes: cost, time and distance. | Colon introduces a list |
| Delhi which is the capital is polluted. | Delhi, which is the capital, is polluted. | Non-defining clause needs commas |
Our trainers see one pattern again and again with Indian English learners and Malayalam speakers. Students learn linking words as a list, memorize them, and then attach them to sentences with a comma because that feels natural in speech. The words are correct. The punctuation is not. Fixing this one habit lifts a lot of essays from band 6.5 to band 7.
The same habit shows up in Reading too. Understanding the use of commas and semicolons to break down lengthy academic sentences becomes very easy with the knowledge of sentence construction and that is why our Read savvy and 40in60 reading classes cover sentence construction apart from the types of questions.
