IELTS vs TOEFL vs Cambridge: Which English Certificate Should You Choose?

When choosing an English certificate for their child, many parents find themselves torn between IELTS, TOEFL and Cambridge, since each one has a different assessment purpose, test format and target group of learners. Comparing IELTS, TOEFL and Cambridge helps parents understand what sets each certificate apart, so families can build an English learning pathway suited to their child's age, level and academic goals. In this article, Westlink breaks down the key differences to help families make the right choice with confidence.

What Are IELTS, TOEFL and Cambridge?

IELTS, TOEFL and Cambridge are all internationally recognised English certificates, but they differ in purpose, administering body and target learner group. Comparing them helps parents and students choose the right certificate for their needs and avoid pursuing the wrong pathway.

IELTS is jointly owned by the British Council, IDP Education and Cambridge English, and is commonly used for study abroad, immigration, university admissions or professional applications.

The test comes in two versions: Academic, for academic purposes, and General Training, for immigration, work or vocational training. Both assess the four skills of Listening, Speaking, Reading and Writing, scored on a 0–9.0 scale. (Source: ielts.org)

TOEFL is developed by ETS, with TOEFL iBT the most common computer-based format for assessing academic English. As of 21 January 2026, the test uses a new 1–6 scoring scale aligned with the CEFR. ETS continues to provide a converted 0–120 score during a two-year transition period (through 2028) to support applicants. (Source: ets.org)

Cambridge English is a tiered certificate system running from Starters, Movers and Flyers through to A2 Key, B1 Preliminary, B2 First, C1 Advanced and C2 Proficiency. These certificates don't expire, making them well suited to students who want to build English step by step over several years. (Source: cambridgeenglish.org)

Should You Choose IELTS, TOEFL or Cambridge?

No single English certificate suits every learner. IELTS, TOEFL and Cambridge only deliver real value when chosen to match a student's age, level, learning goals and how the certificate will actually be used. Before deciding, parents and students should compare IELTS, TOEFL and Cambridge against their own specific needs, rather than simply following the trend.

Choosing an English certificate based on age and goals

For Primary and Lower Secondary Children

For primary and lower secondary students, Cambridge is worth considering, thanks to its tiered system suited to each age group, from Starters, Movers and Flyers through to A2 Key and B1 Preliminary. Test content is grounded in everyday student life, helping children build English gradually without facing academic pressure too early.

It's also a certificate that doesn't expire, making it useful for parents wanting to track their child's progress over time.

For Upper Secondary Students Preparing for University

For upper secondary students, IELTS Academic is usually the right fit if the certificate is needed for university admissions, score conversion or study-abroad applications. Cambridge B2 First or C1 Advanced can be a strong foundation for students who have already been following the Cambridge pathway.

That said, parents should check each university's specific requirements, as not every admissions office accepts the same type of certificate.

For Students Planning to Study Abroad

For students planning to study abroad, the certificate should be chosen based on the destination country and the target school's requirements. TOEFL is usually the right fit for the US or Canada, while IELTS Academic is more widely used across programmes in the UK, Australia and New Zealand.

Some schools also accept Cambridge C1 Advanced or C2 Proficiency, so parents should check each target school's entry requirements before deciding.

Two Approaches to Building English Certification

The Exam-Prep Approach

Exam prep focuses on test structure, question types, exam technique and skill-specific practice. This approach suits students who need a certificate in a short timeframe — for admissions, transferring schools or completing an application. Students with a reasonable existing foundation in English can get familiar with the test format quickly and see a clear improvement in their score.

That said, exam prep should be seen as just one part of learning English, not the whole journey. A high score doesn't necessarily reflect a student's full ability to use English in a real academic setting. Relying only on test-taking tricks can leave students struggling to read in-depth material, write essays, give presentations or take part in discussions in English.

The Academic-Foundation Approach

Building an academic foundation suits students on a long-term international education pathway, where English isn't just a standalone subject but also the tool used to study Maths, Science, Literature, History and take part in research activities. This approach develops language ability, critical thinking, presentation skills and independent learning all at the same time.

Unlike studying purely to pass a test, students here use English in genuine academic situations — reading material, writing analytical pieces, presenting and taking part in class discussions. These are exactly the foundational skills that IELTS, TOEFL and Cambridge assess. Once a student has a solid academic foundation, exam prep later on is largely just a matter of getting familiar with the test format and marking criteria.

At Westlink — an authorised IB World School for the Primary Years Programme (PYP) since May 2024, and also authorised for the Middle Years Programme (MYP) as of December 2025, with the Diploma Programme (DP) currently at Candidate School stage — English is approached as a learning tool through lessons, projects, discussions and presentations suited to each age group.

With an English-medium academic foundation built around IB standards, and support from the International Schools Partnership (ISP), students are better prepared if they later need to sit standardised tests such as IELTS, TOEFL or Cambridge.

When Should You Choose Which Approach?

Early exam prep and building an academic foundation aren't mutually exclusive — they simply suit different circumstances.

Choose early exam prep when:

• Your child doesn't have many opportunities to use academic English across everyday subjects and learning activities.

• Their day-to-day learning environment doesn't involve much academic English.

• The family needs a certificate within the next 1–2 years for a school transfer, an enhanced-English class or an urgent study-abroad application.

Choose an academic-foundation approach when:

• The family has committed to a long-term international education pathway for their child.

• The goal is for the child to use English for study, research and work in an international setting — not just to pass a single test.

• Parents are willing to invest for the long term and want their child to develop language ability, critical thinking and academic skills side by side.

Parents should choose a pathway based on their child's goals

Comparing IELTS, TOEFL and Cambridge shows that Cambridge suits younger students building English step by step, while IELTS and TOEFL are a better fit for upper secondary students, study abroad or university admissions. With a long-term international education focus, Westlink helps students build English every day, laying the groundwork for standardised tests later on.
