Grammar for IELTS counts as one quarter of your Writing score and one quarter of your Speaking score. If you have been scoring at 6 or 6.5 on two or three successive tests, chances are that the issue has nothing to do with your ideas and vocabulary. The problem lies in grammatical range and accuracy. Candidates usually overlook the mark scheme to such an extent that they repeat their mistakes and continue receiving the same score.
In this guide, we will examine the IELTS grammar rules that the examiners will reward you for, the subtle mistakes that lower your score, and how you can solve that age-old question from all students: “How to improve grammar for IELTS?”
At Tiju’s Academy, grammar is not a side topic we cover in one class and forget. It runs through every module we teach. That is one reason students call us the best IELTS coaching centre in Kerala.
What Is Grammatical Range and Accuracy in IELTS?
Grammatical range and accuracy implies the following two aspects at once: variety of sentence structures that you can use, and accuracy in using them.
Range is variety. Can you write a relative clause, a conditional, a passive sentence, and a participle clause without freezing? Accuracy is control. When you use those structures, do they come out clean?
Examiners look at both together, and this is where candidates get trapped:
- Write only short, safe sentences and you stay accurate, but your range stays low. Band 6 at best.
- Write long, ambitious sentences full of errors and your range looks fine, but accuracy collapses. Again, band 6.
- Write a mix of simple and complex sentences, with most of them error free, and you move into band 7 territory.
So the target is not “perfect English.” The target is a good variety of structures with a high proportion of error-free sentences. Once students understand that, their whole practice method changes. In our Tiju’s Academy IELTS classes, we always begin our writing classes by demonstrating to our students precisely where they fall on that spectrum.
How Is Grammar Tested in IELTS?
Grammar is tested as one of four criteria, each of which receives equal weight of 25%, in both Writing and Speaking.
IELTS Writing is marked on:
- Task Achievement (Task 1) or Task Response (Task 2)
- Coherence and Cohesion
- Lexical Resource
- Grammatical Range and Accuracy
IELTS Speaking is marked on:
- Fluency and Coherence
- Lexical Resource
- Grammatical Range and Accuracy
- Pronunciation
Four scores are averaged, which is why even poor performance in grammar will pull down your entire module. You get 7, 7, 7, and 5 in writing. Your band score in writing becomes 6.5. One weak criterion cost you half a band.
How is grammar marked in IELTS Writing?
Examiners work from the public band descriptors. This is how they will assess the criteria at each level in simple terms, not in the technical language that the examiners will use.
| Band | Range | Accuracy |
| 5 | Mostly simple sentences, complex attempts often break down | Frequent errors, punctuation is often faulty, reader has to work |
| 6 | A mix of simple and complex forms | Some errors, but meaning still comes through |
| 7 | A clear variety of complex structures | Frequent error-free sentences, only a few slips |
| 8 | A wide range used flexibly | The majority of sentences are completely error free |
Notice the word frequent at band 7. Nobody is going to check your commas one at a time. The examiner assesses the mistake frequency, which means how frequent your mistakes occur in the entire answer. Two tiny article errors in a 280-word essay are not going to prevent you from scoring a 7. Six tense errors and three run-on sentences will.
This applies to both Academic and General Training. The band descriptors for grammar are the same for both versions of the test.
Why Many Candidates Lose Marks for Grammar?
Most common grammar mistakes in IELTS writing fall into six repeatable patterns. We see the same six every month in our correction sessions, from students at every level.
- The same sentence pattern, forty times
Subject, verb, object. Then again. Then again. English is perfect in here, but there is no variety; thus, the mark remains 6.
It should be improved by mastering five good patterns and using them alternatively. You do not need twenty.
- Complex sentences that fall apart
This is the most common ceiling because students realize they need complex sentences for IELTS writing, so they try to construct long sentences, and in the middle of it, they forget the main verb.
Weak: Although many people believe that technology has improved education, there are students who use phones in class.
Better: Although many people believe that technology has improved education, students who use phones in class often become distracted.
A subordinate clause and a main clause are done. Short and right will always beat long and wrong.
- Articles
Malayalam, Hindi, and Tamil don’t use articles like English, so L1 influence shows up in it the most. Students either omit it entirely or put it everywhere.
Quick rules that solve most cases:
- Plural and uncountable nouns used in a general sense take no article. Governments should invest in public transport.
- Use the when the noun is already known or is unique. The government of Kerala announced the policy.
- Singular countable nouns always need something in front. Never write student should study harder.
- Subject-verb agreement under time pressure
Subject-verb agreement errors are rarely knowledge problems. They are speed problems. The subject and verb get separated by a long phrase and the ending falls off.
The number of students who apply for higher studies abroad have increased.
The subject is number, so it should be has. Reading your answer aloud in your head catches most of these.
- Punctuation
Yes, because punctuation does count in your grammar marks, not your cohesion marks. The most serious fault in this regard is the comma splice.
Wrong: Online learning is convenient, it saves travel time.
Right: Online learning is convenient because it saves travel time.
Run-on sentences and sentence fragments cost marks the same way.
- Fossilised errors
Fossilised errors are mistakes you have repeated for so many years that they feel correct. Discuss about, I am agree, most of the people, he told me to not go. No amount of general reading removes these. They have to be identified, fixed and practiced, which is precisely the point of our grammar classes.
How Can I Improve Grammar for IELTS Writing?
The quickest way to get better at grammar in IELTS Writing Task 2 is to stop learning grammar altogether and concentrate on fixing your mistakes instead. That single shift saves most students weeks of wasted effort.
Here is the method we teach at Tiju’s Academy, which our students follow for four to six weeks.
Build an error log
Take all corrected essays and record your mistakes in a notebook divided into three columns that include the incorrect sentence, the corrected sentence, and the type of mistake.
Most students find something quite unpleasant and yet very useful. They are not making fifty different mistakes. They are making four mistakes fifty times. Once you know your four, you can fix them.
Learn five structures properly
- Avoid listing all grammatical rules and learn the ones mentioned below:
- Defining and non-defining relative clauses. Students who go to study abroad are usually under financial stress. My home town, which has three universities, attracts many youngsters.
- Conditional sentences. First for real future situations, second for hypothetical ones, and third for the past. If governments raised fuel taxes, car use would fall.
- Passive voice for processes and formal statements. The waste is collected and then sorted by hand.
- Participle clauses for compressing two ideas. Having completed the course, many graduates move overseas.
- Modal verbs for opinion and degree. This may lead to overcrowding rather than solving it.
Five structures used well will carry you further than twenty half-learned ones.
Combine sentences on purpose
Take any two simple sentences from your own writing and join them three different ways. Ten minutes a day. It is the quickest way to develop range because you are practicing using your vocabulary.
Which tenses are used in IELTS Writing Task 1?
The tenses for Academic Task 1 are based purely on the dates provided in the chart.
- Past dates – past simple. Car ownership increased dramatically between 1990 and 2005.
- Future dates or projections, use future forms. Numbers are expected to double by 2035.
- No dates at all, use present simple.
- Process diagrams, use present simple passive. The beans are then dried and packed.
For General Training letters, match the tense to the situation. Complaint letters usually need past simple and present perfect together. I bought the item last month and it has stopped working twice since then.
Self-edit with a checklist
Save the last two minutes of every writing task for proofreading. This is where our IELTS grammar checklist before submitting comes in:
- Does every sentence have a subject and a main verb?
- Are singular subjects matched with singular verbs?
- Have I checked every “a,” “an,” and “the”?
- Are any two sentences joined by only a comma?
- Are my tenses consistent with the time frame?
- Have I used at least three different complex structures?
These students usually eliminate two to four mistakes per essay when they apply this checklist during timed writing practice. This may be the deciding factor in moving from 6.5 to 7.
IELTS Speaking Grammar: Grammar without Sacrificing Fluency
IELTS Speaking grammar is evaluated based on the same principle of range and accuracy, but natural spoken English is expected rather than English read out loud.
Is grammar important in IELTS Speaking? Absolutely, it accounts for 25% of your speaking score. However, thinking about the use of a verb for three seconds will cost you more points in Fluency and Coherence than the mistake itself would cost in grammar. Speak, fix yourself right away if you hear the mistake, and keep speaking.
What examiners want to hear in all three parts:
- Part 1: clean present simple and past simple with a few natural contractions. Short answers are fine, but add one supporting sentence.
- Part 2 cue card: consistent past tense narration, plus one or two conditionals or comparatives.
- Part 3 speaking: this is where range shows. Try using examples, passive voice and modals. With more work from home, there would be much less traffic in cities.
Fluency vs. accuracy is a dilemma many students face. Our Fluent Sphere sessions solve it by training students to speak in slightly shorter thought groups, which keeps grammar under control without creating hesitation.
How Band 7+ Candidates Use Grammar Effectively
Band 7 grammar in IELTS looks calmer than most students expect. Strong candidates do not write dramatic, complicated sentences. They write clear ones with controlled variety.
Compare these two paragraphs on the same topic.
Band 6 version:
Many people are using social media today. Social media is having many bad effects. People are spending too much time on it. They are not talking with family members. This is a problem for society.
Every idea is correct. Every sentence is the same shape. There is no complex structure anywhere.
Band 7+ version:
Social media has taken up a good number of hours within each day for most individuals, affecting the way that family members relate at home. Since all conversations take place on the screen, most families spend their evenings together, yet they do not communicate verbally. Should this continue, the cost socially will be higher than the benefit gained from these mediums.
Look at what changed:
- One compound sentence joined with and
- One subordinate clause opening with Because
- One conditional with a modal verb
- Nominalisation used once, in the social cost
- A stronger noun phrase, several hours of the average person’s day
No rare grammar. No showing off. Three sentences, three different structures, zero errors.
Can I get band 7 with grammar mistakes?
Yes. Band 7 does not require perfection. It requires frequent error-free sentences and only a few errors overall. What blocks band 7 is not the occasional slip. They are repeated errors of the same type across the whole answer, which signals a gap in control rather than a lapse in concentration.

Frequently Asked Questions:
A: Grammar is one of four marking criteria in both Writing and Speaking, and it carries 25% of each module score. The four scores are averaged, so a weak grammar score pulls the whole band down. Scores of 7, 7, 7 and 5 in Writing give you 6.5.
A: Grammatical range and accuracy means two things at once. Range is the variety of sentence structures you can use, such as relative clauses, conditionals and passives. Accuracy is how correctly you use them. Examiners judge both together, so you need variety and control.
A: There is no fixed number. Examiners judge how often mistakes appear across your whole answer, not a mistake count. Two small article slips in a 280-word essay will not stop a band 7. Six tense errors and three run-on sentences will.
A: Yes. Grammatical Range and Accuracy is 25% of your Writing score and 25% of your Speaking score. Repeated errors of the same type do more damage than occasional isolated slips, because they signal a gap in control rather than a lapse in concentration.
A: Yes. Band 7 does not require perfect English. It requires frequent error-free sentences with only a few slips overall. What blocks band 7 is the same error repeating across the whole answer, not the occasional mistake.
A: You need controlled variety, not rare grammar. Five structures are enough: relative clauses, conditionals, passive voice, participle clauses and modal verbs. Band 7 writing looks calmer than most students expect, with clear sentences and different structures rather than long complicated ones.
A: Usually because your simple sentences are clean but your complex ones contain errors. The examiner sees range without accuracy. Another common cause is using the same sentence pattern throughout, which keeps accuracy high but range low. Both cases land at band 6.
A: Stop studying grammar in general and fix your own repeated errors instead. Keep an error log with three columns: the wrong sentence, the correction, and the error type. Most students find they are making four mistakes fifty times, not fifty different mistakes.
A: Tense choice depends on the dates in the chart. Use past simple for past dates, future forms for projections, present simple when there are no dates, and present simple passive for process diagrams. General Training letters often need past simple and present perfect together.
A: Yes, it carries 25% of your speaking band. But pausing for three seconds before every verb costs more in Fluency and Coherence than the error would cost in grammar. Speak, correct yourself quickly if you notice a slip, and keep going.
