What Is IELTS? A Parent’s Guide to Choosing the Right English Pathway What is IELTS, and does your child really need to start preparing for it from secondary school? This is a question many parents ask when their child is on an international programme, yet it's rarely answered clearly. This article is written from the perspective of an international school teaching the IB curriculum, to help parents understand what the IELTS exam actually is and where it belongs in their child's long-term education pathway. What is IELTS? The basic definition parents need to know IELTS stands for the International English Language Testing System. It is an exam that assesses English language proficiency for non-native speakers. The test is designed by Cambridge English Language Assessment. In Vietnam, there are two official test providers: IDP Education and the British Council. Both use the same test paper, so neither provider's version is easier than the other's. The four skills IELTS assesses IELTS doesn't test grammar in isolation. The exam assesses a candidate's ability to use English across four integrated skills. Listening: understanding conversations, monologues and academic lectures Reading: understanding academic texts or everyday texts Writing: writing a report, describing data, and writing an argumentative essay Speaking: communicating directly with an examiner What sets IELTS apart from many other English exams is that the Speaking section is a face-to-face interview with a real examiner, not conducted on a computer. Understanding IELTS helps students choose the right English pathway. Types of IELTS test IELTS has two main test types, serving two different purposes. IELTS Academic is for people going on to study abroad at undergraduate or postgraduate level, or applying to practise a profession overseas. The content is highly academic. IELTS General Training is for people planning to migrate, work, or take part in vocational training in English-speaking countries. The content is closer to everyday life and the workplace. Both types share the same Listening and Speaking sections. The Reading and Writing sections differ in content. Parents whose child is going abroad for university should choose the Academic version. An IELTS certificate is only valid for two years from the test date. After two years, most universities and immigration authorities no longer accept the result. The reason is simple: language ability changes over time. Someone who scored 7.0 at age 16 but hasn't used English regularly for the following three years may well be at a different level by then. This is a point parents should think through carefully before letting their child sit the test too early. If a child takes it in Year 9, the certificate will have expired by the time they apply to university in Year 12. IELTS test structure and how the 9.0 scoring works A full IELTS test takes almost three hours. The structure is the same whether taken on paper or on a computer — only the format of answering differs. Section Duration Number of questions Format Listening 30 minutes, plus 10 minutes to transfer answers if on paper 40 questions 4 recordings of increasing difficulty Reading 60 minutes 40 questions 3 long passages for Academic, or several shorter passages for General Writing 60 minutes 2 tasks Task 1 around 150 words. Task 2 around 250 words Speaking 11 to 14 minutes 3 parts Face-to-face interview with an examiner Note: the Listening and Speaking sections are identical across both the Academic and General Training versions. The Speaking section is taken with a real examiner, unlike TOEFL, which is computer-based. Writing Task 2 carries two-thirds of the total Writing score and is the most difficult part for Vietnamese students. The IELTS 0 to 9.0 scale IELTS uses a scale from 0 to 9.0, with the smallest increment being 0.5. There's no concept of a pass or fail. Every candidate receives a band score reflecting their overall English proficiency. The Overall score is the average of the four skills, then rounded according to the following rule: A decimal of .25 rounds up to .5 A decimal of .75 rounds up to the next whole band Any other decimal rounds to the nearest 0.5 Illustrative examples: Case 1: Listening 7.0, Reading 6.5, Writing 6.0, Speaking 7.0. Average = 6.625. Rounds to an Overall of 6.5. Case 2: Listening 7.5, Reading 7.0, Writing 6.5, Speaking 7.0. Average = 7.0. Overall 7.0. What the band scores mean for parents: Band 4.0 to 5.5: basic English use, enough for simple communication Band 6.0 to 6.5: sufficient for most universities outside the top tier Band 7.0 to 7.5: needed for top universities and competitive scholarships Band 8.0 and above: very strong proficiency, meeting the demands of fields such as Medicine, Law and Education Parents don't need to understand the detailed marking criteria for Writing and Speaking. What matters is that the target band score should be based on the requirements of the university your child wants to attend, not simply on "as high as possible". An IELTS score reflects actual proficiency — there's no concept of passing or failing What is IELTS used for? When is it actually necessary? Understanding what IELTS is isn't enough on its own — parents also need to know what it's used for and when their child genuinely needs it. IELTS is a widely recognised international English certificate, but widely recognised doesn't mean everyone needs it. Studying in English-speaking countries IELTS is an almost mandatory requirement when applying to university in the UK, Australia, Canada and New Zealand. The commonly required score usually ranges from 6.0 to 7.5, depending on the subject and level of study. Top universities typically require 7.0 or above. Some specialist fields, such as Medicine, Pharmacy, Law and Education, often require 7.5 or above, sometimes with a minimum of 7.0 required in every individual skill. University admissions in Vietnam An increasing number of leading universities in Vietnam use IELTS for admissions or to award bonus points. Some universities also use IELTS as the foreign-language graduation requirement for students. Parents should check the specific admissions scheme of the university their child is interested in directly, since this policy can change from one admissions cycle to the next. Many universities in Vietnam use IELTS for admissions or priority points Immigration and working abroad IELTS General Training is a common requirement for immigration visas to Australia, Canada, New Zealand and the UK. The required score depends on the programme, but is usually 6.0 or above. Some professions in Vietnam also favour candidates with an IELTS score, particularly English teachers at international schools, international tour guides, and international divisions of multinational banks. When you don't need IELTS This is something few test-prep centres tell parents outright. Students on the IB Diploma programme may have their IB English score accepted by many universities in place of IELTS. Students applying to universities that use SAT, ACT or TOEFL also don't need IELTS. Students on the UK A-Level system are often accepted with an A-Level English Language score in place of IELTS at many universities. How much does the IELTS test currently cost?

IELTS vs IB English, SAT, TOEFL: what should parents understand? Once you understand what IELTS is, the next step is to compare it against other international English certificates. IELTS is one of several options, and parents should understand the alternatives to choose the right one for their child. Criterion IELTS TOEFL iBT IB English SAT Nature Standalone English exam Standalone English exam A subject within the IB programme General academic aptitude test Assesses 4 English skills 4 English skills Reading, writing, literary analysis English reading/writing and Maths Speaking section Face-to-face with an examiner Via computer Assessed through the subject None Most widely used in UK, Australia, Canada, New Zealand US Globally, for IB students US Validity 2 years 2 years No expiry, as it's a DP score 5 years Best suited for Studying abroad, immigration, university admissions Studying in the US Students on the IB Diploma Applying to US universities IELTS vs TOEFL The short answer: check which one your child's target university requires. Most universities in the UK, Australia, Canada and New Zealand prefer IELTS. Most US universities prefer TOEFL but still accept IELTS. Universities in Singapore and Hong Kong accept both. Vietnamese students often do better in the IELTS Speaking section than in TOEFL's, because IELTS is taken with a real person and allows for interaction. TOEFL is computer-based, which creates more time pressure. IELTS vs IB English This is the most important point for parents whose child is on an international programme. IB English isn't a standalone exam. It's a subject within the IB Diploma programme. A student who completes the IB Diploma with a sufficiently high IB English score may have the IELTS requirement waived by many universities. This means a student on the IB Diploma pathway may not need to sit IELTS at all, if they choose a university that accepts IB English as a substitute. This is why parents shouldn't put their child through IELTS preparation too early once they've chosen the IB programme. IELTS vs SAT The SAT assesses general academic aptitude, not just English. It's mainly used for US universities. Students applying to US universities typically sit both SAT plus TOEFL or IELTS. The SAT doesn't replace IELTS, and vice versa. Choosing the right certificate saves students time on preparation and money on exam fees Alt: comparing IELTS and TOEFL A quick decision rule for parents Studying in the UK or Australia: prioritise IELTS, or the IB Diploma if your child is already on that pathway Studying in the US: SAT plus TOEFL or IELTS On the IB Diploma: check your target university's IELTS-waiver policy before signing up for test preparation For immigration purposes: IELTS General Training When should your child start being introduced to IELTS? Once you're clear on what IELTS is and when it's actually needed, the next question is when your child should be introduced to this exam. This is the most important question, and also the one most parents get wrong. Introducing IELTS to a child should happen at the right time — not too early, and not too late. Is IELTS suitable for primary-school students? No. IELTS isn't designed for primary-school students. The test requires candidates to discuss topics such as the environment, technology, education, healthcare and urbanisation. Even a young student with strong English will struggle to bring enough depth to handle these topics. The problem with the trend of IELTS prep from primary and early secondary school Many parents today start their child on IELTS preparation from Year 4 or Year 5. This trend creates three real problems. First, the child learns to pass a test rather than to use the language — English becomes a tool for working through exam questions instead of a tool for thinking and communicating. Second, the certificate expires before it's needed — a child who sits the test in Year 7 will find the certificate is already more than two years old by Year 12. Third, it creates unnecessary pressure at an age when the child should still be building foundations. IELTS preparation at lower- and upper-secondary level should be considered carefully, rather than followed simply because it's trending. What foundation should come before IELTS? A high IELTS score doesn't come from drilling practice tests. It comes from a solid foundation in academic English. Students need to develop four capabilities before being introduced to IELTS: Understanding complex academic texts, not just short stories or simple reading passages Writing an argumentative essay with evidence and a clear structure Critical thinking, since both Writing Task 2 and Speaking Part 3 require this skill Vocabulary across academic topics such as the environment, technology, education and society This is exactly what a long-term international education programme builds in students from an early age. At Westlink, students develop these capabilities through an all-through IB pathway built to international standards, alongside a personalised EAL (English as an Additional Language) support programme for students who need it. Students need an academic foundation before intensive IELTS preparation can be effective Alt: the right time to start learning IELTS The right time to be introduced to IELTS For students on an international programme, the right time is usually: End of Year 10 or start of Year 11: take a mock test to gauge the current level End of Year 11 or start of Year 12: focused preparation for 3 to 6 months if the target university requires it Students on the IB Diploma: may not need to sit it at all, if their university accepts IB English Introducing IELTS at lower- and upper-secondary level during this window makes far more sense than starting early, from primary school. An international English pathway for your child The best way for your child to achieve a high IELTS score isn't early test preparation. It's building a foundation in academic English through a long-term education programme. This is the education pathway, from the Early Years through to Year 12, that Westlink has built to IB standards. Westlink is a school officially recognised by the International Baccalaureate Organization (IB) for the PYP programme since May 2024 (according to the IBIS system). As part of the International Schools Partnership (ISP) network — 121 schools across more than 26 markets, Westlink builds an academic English pathway to international standards for students from the Early Years through to Year 12. Primary and PYP, ages 5 to 11 At this level, there's no test drilling and no exposure to IELTS. Students develop their English through genuine hands-on exploration — asking questions, running experiments, working on projects. A multicultural environment with students from more than 30 nationalities helps children use English naturally every day, both in their learning and in how they communicate. The goal at this stage is for English to become a tool for thinking, exploring and connecting with the world — not just a subject on the timetable. Students develop their English naturally through projects and hands-on exploration Secondary and MYP, ages 11 to 16 This is the critical stage for building the foundation for IELTS, IB English, or any international certificate later on. Students develop the ability to understand complex academic texts, write argumentative essays with evidence, and build presentation skills and critical thinking. They also expand their vocabulary across a range of global topics. For students who need extra support with English, the EAL (English as an Additional Language) programme provides a personalised learning pathway matched to each student's level. This is also the stage when parents can start thinking about introducing IELTS to their child — but only towards the end of MYP, from Year 9 onwards, not earlier. The MYP stage builds critical thinking and in-depth academic writing skills IB Diploma, Years 11 to 12 By the time they enter the IB Diploma programme, students usually already have a solid foundation in academic English. They work with the Future Pathways advising team to build their university pathway. If the target university accepts the IB Diploma, or waives the IELTS requirement based on an IB English score, students may not need to sit the test at all. Where IELTS is a firm requirement, most students only need 3 to 6 months of preparation towards the end of Year 11 or the start of Year 12 to reach the score they need. For a US study pathway, students focus instead on SAT and TOEFL. A genuine international school prepares many pathways A genuine international school doesn't exist so your child can score high on IELTS. It exists so your child has many options for the future. IELTS is just one of them. On completing the IB Diploma at Westlink, students have multiple options for their next step: a UK or Australian university with their IB score, a US university with SAT plus IB, a leading Vietnamese university with IELTS or IB, or a European or Asian university with the IB Diploma. An academic English foundation serves all of these pathways, not just one. A long-term international pathway helps students reach a high IELTS score without starting early What is IELTS is no longer a difficult question after reading this far. The real question is choosing the right pathway, so your child isn't rushed into test preparation in their final years of school. A solid academic English foundation built early gives your child the confidence to face any exam — not just IELTS. If you'd like to understand this pathway for your child, the Westlink team is ready to advise on the right academic English approach for each age group.
