The goal is achievable and this piece keeps the 8.5–9.0 target intact. But one number forces the plan to change, and it has nothing to do with the child’s ability — it is arithmetic: an IELTS score expires after exactly two years.
This question comes up constantly, and it comes from a good place: parents want their child ahead, and want to use the years when a young brain takes on language most readily.
8.5–9.0 is a good target. This piece keeps it.
But one number forces the plan to change, and it has nothing to do with how capable your child is.
An IELTS score is valid for exactly two years from the test date, and cannot be extended.
Do the arithmetic. Your child is ten, in the last years of primary school, and suppose they genuinely score 8.5. By the time they are twelve, that certificate has expired. When they apply to university at eighteen, it has been dead for six years. No university will take it. No consulate will take it.
So sitting IELTS in primary school is not merely hard on the child. It throws away the very score it produces.
The right answer is therefore not lower your ambition. It is: keep the 8.5–9.0 target, move the test date to a point where the score is still usable, and spend the primary school years building the thing that makes 8.5–9.0 possible at all.
That is the road below.
First: IELTS is not recommended under sixteen. This comes from the test owners themselves. The British Council and IDP terms state that the paper and computer tests are not recommended for persons under sixteen years of age. IELTS Online does not accept test takers under eighteen at all. The reason is not age discrimination; it is that the test content is built for cognitively mature candidates.
Second: the certificate expires after two years. Said above, but it governs the entire schedule, so it bears repeating.
Third: 8.5–9.0 is far rarer than it feels. The official IELTS figures for 2024–2025 that I could verify are a Listening mean of 6.45 and an Academic Reading mean of 6.32. The widely quoted claim that fewer than 2% of test takers reach band 8 or above in Writing I could not confirm against the official source — the IELTS statistics page publishes the detailed breakdown only in a downloadable file I was unable to read. Treat it as an indicative figure, not a verified one.
This is the most important section, because it determines where your money and time should go.
The IELTS descriptor for band 9 is fully operational command of the language — appropriate, accurate, fluent, with complete understanding.
Now look at the hardest part: Writing Task 2. The candidate has about 40 minutes to write at least 250 words presenting an argument on themes like education, environment, technology, health and society.
IELTS is explicit that no specialist knowledge is required, and that is true. But something else is required: the ability to build and sustain an abstract argument about social policy for forty minutes.
And here is a test you can run tonight, for free:
Give your child a Writing Task 2 prompt and ask them to answer it in Vietnamese.
For instance: Some people believe governments should spend more on public transport than on roads. To what extent do you agree? — 250 words, mother tongue, forty minutes.
If a ten-year-old cannot construct that argument in their own first language, the ceiling is cognitive development, not English. And no IELTS course moves that ceiling, because the missing ingredient is not vocabulary.
This is what Cummins (1979, 2000) described in distinguishing everyday conversational language from academic language: a child can be fluent in the playground very early, while academic language proficiency takes years longer. Kellogg (2008) shows that argumentative writing skill develops late and slowly, continuing well into adulthood.
The good news: that gap closes on its own with time, provided the language foundation is built properly. And the foundation can be built starting now.
Each step has a measurable milestone. These use the Cambridge ladder, because it is the system actually designed for these ages — and it still gives the child certificates and visible progress, which is what parents are usually looking for when they consider early IELTS.
The job at this stage is the ear, not a score.
Large amounts of listening: songs, stories, cartoons with English subtitles. Alongside it, phonics — teaching the mapping between letters and sounds. Ehri (2005) and the National Reading Panel (2000) both found systematic phonics instruction to be the most reliable route into reading.
Milestone: Pre A1 Starters — the Cambridge test for children around 7–8, after roughly 100 hours of English. Nobody fails it; everyone receives shields. At this age that matters.
This is the heaviest step on the road, and the one most often skipped.
The aim is a child who reads English books because they want to, not because it was set as homework. Use graded readers, and apply the rule from this site's article on literary books: if a page has more than about five unknown words, that book is not for them today.
Nakanishi (2015) meta-analysed extensive reading research and found consistent positive effects on both reading ability and vocabulary.
Milestone: A1 Movers — usually taken between 8 and 11, after roughly 175 hours.
This is the end of primary school, and it is where a primary school child should be.
Milestone: A2 Flyers, or A2 Key for Schools.
An eleven-year-old with solid A2 is doing very well. If that number looks modest next to 8.5, remember: it is the third rung of the same ladder that leads there.
In lower secondary, abstract reasoning starts to come online. Only now does it make sense to teach paragraphs with a claim, evidence and a conclusion.
Milestone: B1 Preliminary for Schools.
B2 corresponds to roughly IELTS 5.5–6.5 — the level where a great many adults stop permanently. Your child reaches it at fifteen, with three years in hand.
Milestone: B2 First for Schools. The content is written around school-age interests, though the level matches the standard version.
Milestone: C1 Advanced, roughly IELTS 7.0–8.0.
At this point, for the first time, 8.5–9.0 becomes a reasonable target rather than a slogan.
Old enough for the recommended age. Cognitively ready for Task 2. And most importantly: the score is still valid for university applications at eighteen.
Actual exam preparation needs only three to six months, because all you are teaching is the format of a test to someone who already has the English. For building the reading and writing habits that phase depends on, see this site's separate piece on IELTS habits.
This is where the 8.5–9.0 target belongs.
So you can see it is all one ladder:
A2 — below the IELTS scale. B1 — about 4.0–5.0. B2 — about 5.5–6.5. C1 — about 7.0–8.0. C2 — about 8.5–9.0.
Honest note: this is an approximate mapping used for orientation. It is not an official conversion, and no body guarantees exact equivalence.
Not exam drills. These four things, and all four can begin in primary school.
Reading volume. Nation (2006) estimates eight to nine thousand word families for reading novels without lookups; Hu and Nation (2000) put comfortable reading at about 98% known words. There is no shortcut to those numbers except reading widely, for years.
Listening volume. Daily, uninterrupted, measured in years.
A writing habit. Short but regular, and read and corrected by someone. Writing without feedback is practising your errors.
Time. This is the one thing money cannot buy, and it is the thing a primary school child has most of. That is the real advantage of starting early — not an early certificate, but the years.
Cepeda et al. (2006) show that spreading study across time produces far more durable memory than massing it. Ten steady years beat two crammed ones, and not by a small margin.
Drilling IELTS format with a nine-year-old. The child learns test tricks with no language underneath. The tricks stop working quickly as the material gets harder.
Mistaking high Reading and Listening scores for strong English. Receptive skills always run ahead of productive ones. A child can genuinely score 8.0 in Reading and 5.5 in Writing — and Writing is what decides an overall 8.5.
Testing too often. Every exam consumes time that should have gone into learning. Certificates are for measuring, not for learning.
Trading a love of the language for a score. A child who hates English at eleven will not score 8.5 at seventeen. This is the largest risk and the most frequently underestimated one. This site's roadmap for six-year-olds treats that point at greater length.
Two policy changes matter for long-range planning.
Circular 06/2026/TT-BGDĐT provides that a language certificate may be used in one of two ways: converted into the English component of an admission combination, or counted as bonus points — the candidate must choose, and cannot have both.
And since December 2025, the Prime Minister has approved the project to make English a second language in schools, running 2025–2035 with a vision to 2045.
Both point the same way: the value of the certificate is falling while the value of genuine ability is rising. That argues further for building the foundation rather than collecting early paper.
You asked for a step-by-step road to 8.5–9.0 for a primary school child. This is that road, in full, and the target has not been lowered.
Exactly one thing changed: the test date. Not because your child is not capable, but because the certificate expires after two years, and an 8.5 earned at ten will not exist by the time it is useful.
The first step on this road is not an IELTS class.
It is an eight-year-old finishing an English book because they wanted to know how it ended.
The same article, told in plain words — for younger readers, or for anyone who wants the point quickly.
This question comes up constantly, and it comes from a good place: parents want their child ahead, and want to use the years when a young brain takes on language most readily.

Each step has a measurable milestone. These use the Cambridge ladder, because it is the system actually designed for these ages — and it still gives the child certificates and visible progress, which is usually what parents are looking for when they consider early IELTS.
Step 1 — ages 6 to 8: sound before spelling. The job at this stage is the ear, not a score. Large amounts of listening: songs, stories, cartoons with English subtitles. Alongside it, phonics — teaching the mapping between letters and sounds. Ehri (2005) and the National Reading Panel (2000) both found systematic phonics instruction to be the most reliable route into reading. Milestone: Pre A1 Starters, the Cambridge test for children around 7–8, after roughly 100 hours of English. Nobody fails it; everyone receives shields. At this age that matters.
Step 2 — ages 8 to 10: reading alone. This is the heaviest step on the road, and the one most often skipped. The aim is a child who reads English books because they want to, not because it was set as homework. Use graded readers, and apply the rule from this site's article on literary books: if a page has more than about five unknown words, that book is not for them today. Nakanishi (2015) meta-analysed extensive reading research and found consistent positive effects on both reading ability and vocabulary. Milestone: A1 Movers, usually taken between 8 and 11, after roughly 175 hours.
Step 3 — ages 10 to 11: reach A2, and stop in the right place. This is the end of primary school, and it is where a primary school child should be. Milestone: A2 Flyers, or A2 Key for Schools. An eleven-year-old with solid A2 is doing very well. If that number looks modest next to 8.5, remember: it is the third rung of the same ladder that leads there.
Step 4 — ages 11 to 13: B1, and writing gains structure. In lower secondary, abstract reasoning starts to come online. Only now does it make sense to teach paragraphs with a claim, evidence and a conclusion. Milestone: B1 Preliminary for Schools.
Step 5 — ages 13 to 15: B2. B2 corresponds to roughly IELTS 5.5–6.5 — the level where a great many adults stop permanently. Your child reaches it at fifteen, with three years in hand. Milestone: B2 First for Schools, written around school-age interests though the level matches the standard version.
Step 6 — ages 15 to 16: C1. Milestone: C1 Advanced, roughly IELTS 7.0–8.0. At this point, for the first time, 8.5–9.0 becomes a reasonable target rather than a slogan.
Step 7 — ages 16 to 17: now sit IELTS. Old enough for the recommended age. Cognitively ready for Task 2. And most importantly: the score is still valid for university applications at eighteen. Actual exam preparation needs only three to six months, because all you are teaching is the format of a test to someone who already has the English. This is where the 8.5–9.0 target belongs.
So you can see it is all one ladder: A2 — below the IELTS scale. B1 — about 4.0–5.0. B2 — about 5.5–6.5. C1 — about 7.0–8.0. C2 — about 8.5–9.0.
