IELTS vs TOEFL vs Cambridge: Which English Exam Do You Actually Need?

You're studying for the wrong exam

Here's a scenario that happens more than it should: someone spends three months preparing for IELTS, books the test, scores a 7.0 — and then discovers the Canadian immigration stream they want specifically requires a CELPIP result, or that the master's programme they applied to prefers Cambridge C1 Advanced. Three months. Gone.

Choosing between IELTS, TOEFL, and Cambridge is not a matter of 'which one is easier.' They test different things, they're accepted in different places, they expire on different timelines, and they cost meaningfully different amounts. This post will walk you through exactly how to choose — not based on vague impressions, but based on your actual goal.

What are the three exams, at a glance?

Before we compare, a quick orientation so we're speaking the same language.

IELTS (International English Language Testing System) is jointly owned by British Council, IDP, and Cambridge Assessment English. It comes in two versions: Academic (for university and professional registration) and General Training (for immigration and work). It reports a band score from 1 to 9, in half-band increments.

TOEFL iBT (Test of English as a Foreign Language, internet-based) is owned by ETS (Educational Testing Service). It was scored 0–120 for decades; ETS replaced that with a new 1–6 band scale in 2026, though most university requirement pages still list the old 0–120 thresholds. It's almost exclusively used for university admissions — particularly in the US — and it's delivered entirely online.

Cambridge English Qualifications (B2 First / FCE, C1 Advanced / CAE, C2 Proficiency / CPE) are fixed-level exams awarded by Cambridge Assessment English. Unlike IELTS and TOEFL, they don't expire. You pass, you have a certificate for life. They're pegged directly to CEFR levels (B2, C1, C2).

Which exam should I take for university?

For university admissions, all three are broadly accepted — but acceptance is not the same as preference, and the geography matters enormously.

If you're applying to universities in the United States, TOEFL iBT is the historic default. Most US universities list it first on their requirements page, and some older departments still only explicitly mention TOEFL in their requirements, though nearly all now accept IELTS Academic too. If your target is a US institution, check whether they accept IELTS — most do — but when in doubt, TOEFL is the safer choice.

If you're applying to universities in the United Kingdom, Australia, Canada, New Zealand, or Ireland, IELTS Academic is the dominant standard. UK universities and UKVI (UK Visas and Immigration) are deeply familiar with IELTS band scores; admissions staff can read a 6.5 or 7.0 instantly. Cambridge qualifications are also well-recognised at UK universities — a C1 Advanced pass is often cited as equivalent to IELTS 6.5–7.5, depending on the grade (per Cambridge Assessment English's own score comparison tables).

Cambridge qualifications carry particular weight if you want something permanent on your CV. Because they never expire (unlike IELTS and TOEFL, which are only valid for two years per their respective test policies), a Cambridge certificate earned at 22 is still valid when you apply for a job at 35. For university applications specifically, this doesn't help much — you need a recent score for admissions — but if you're thinking beyond the application, Cambridge is the better long-term investment.

• US universities → TOEFL iBT is the historic standard; IELTS Academic widely accepted
• UK / Australia / Canada / NZ → IELTS Academic is dominant; Cambridge also accepted
• European universities (non-English-medium) → Cambridge qualifications often preferred for visa and credit purposes
• Checking individual programme pages beats any general rule

Which exam should I take for immigration?

This is where the choice becomes very concrete, very fast — because immigration authorities often mandate a specific test, and submitting the wrong one means rejection regardless of your English level.

UK immigration: UKVI (UK Visas and Immigration) requires an approved Secure English Language Test (SELT) for most visa categories. The only IELTS product approved for this is IELTS for UKVI — not the standard IELTS Academic or General Training. TOEFL and Cambridge qualifications are not on the UKVI-approved SELT list — always check the official UKVI Approved Tests page for the current list, as it updates.

Canadian immigration: Immigration, Refugees and Citizenship Canada (IRCC) accepts IELTS General Training, CELPIP-General and PTE Core for most economic immigration streams. TOEFL is not accepted for Canadian immigration. Neither are Cambridge qualifications for most IRCC pathways. If you're planning to move to Canada, IELTS General Training is almost always the exam you need.

Australian immigration: The Department of Home Affairs accepts IELTS, TOEFL iBT, PTE Academic, OET and — unlike most countries — Cambridge C1 Advanced. IELTS General Training is still the most common choice, but Australia is the one major destination where a Cambridge result can double as an immigration test result.

US immigration: The US does not have a standardised English test requirement for immigration in the same way. English proficiency requirements vary by visa type and are often assessed through interview rather than a standardised test.

The hard lesson: if you're taking an exam for immigration, go to the official government website of the destination country and confirm which specific tests are accepted before booking anything.

Which exam should I take for work or professional registration?

Professional registration bodies — medical councils, nursing boards, legal associations — often have their own requirements that differ from universities and immigration authorities.

The UK's Nursing and Midwifery Council (NMC) and General Medical Council (GMC) both have specific IELTS score thresholds (the NMC asks for IELTS Academic 7.0 overall with high per-skill minimums — it currently allows 6.5 in Writing — per their published guidance). OET (Occupational English Test) is an alternative designed specifically for healthcare — worth considering if you're in that field, though it's outside this article's three-exam scope.

For general workplace English — a job offer in an English-speaking country, or demonstrating proficiency to an employer — Cambridge qualifications are often the most useful long-term credential precisely because they don't expire. A C1 Advanced certificate on a CV signals sustained proficiency without requiring you to re-sit an exam every two years. IELTS and TOEFL scores, by contrast, are only valid for two years from the test date (per IELTS' and ETS's own policies), which means an employer looking at your CV three years later sees an expired score.

If your goal is purely professional recognition — not immigration, not university — and you want a permanent English credential, Cambridge is usually the smartest choice.

What do the scores actually mean, honestly?

Score equivalences between these three exams are approximate — all three measure slightly different things — but Cambridge Assessment English publishes a comparison table that gives a reasonable starting point. Here's what the alignment looks like across CEFR levels, using Cambridge's own published comparisons and ETS's TOEFL–CEFR alignment research as the basis. The TOEFL figures below use the long-standing 0–120 scale, because that is still what most university pages list — if you have a result on the new 1–6 scale, convert it first:

• C2 (Cambridge CPE pass) ≈ IELTS 8.5–9.0 ≈ TOEFL iBT 110–120
• C1 (Cambridge CAE pass) ≈ IELTS 7.0–8.0 ≈ TOEFL iBT 95–109
• B2 (Cambridge FCE pass) ≈ IELTS 5.5–6.5 ≈ TOEFL iBT 72–94
• B1 ≈ IELTS 4.0–5.0 ≈ TOEFL iBT 42–71

The honest caveat on score equivalences

Those equivalences above are widely used but imperfect. IELTS measures four skills (Reading, Listening, Writing, Speaking) equally and reports both a total band and individual band scores. A university requiring IELTS 6.5 overall with no band below 6.0 is enforcing a much more specific requirement than just '6.5 overall' — you can score 7.5 in Listening and 5.5 in Writing and fail to meet the requirement even with a fine overall band.

TOEFL iBT weights the four skills into a total score of 120, but the scale is not proportional to IELTS bands in a linear way. A TOEFL 100 is solidly C1, but two candidates with TOEFL 100 can have very different Writing sub-scores. When a university says 'TOEFL 90 or IELTS 6.5,' they're treating those as roughly equivalent — but the profile of skills they're measuring is different.

Cambridge qualifications report a pass/fail result (with grades: Pass with Merit, Pass with Distinction) plus a Cambridge English Scale score between 160 and 210. A score of 180 on the Cambridge English Scale corresponds to approximately C1, and 200 corresponds to C2 — per Cambridge Assessment English's published scale. The benefit of Cambridge is that your certificate specifies your CEFR level, which is increasingly the language that universities, employers, and governments use.

How much does each exam cost, and how long is it valid?

Cost varies by country, so the figures below are approximate ranges drawn from publicly listed test centre prices — always confirm the current fee on the official website for your location before booking.

IELTS: approximately USD 215–250 (or local equivalent) depending on country and test centre. Valid for 2 years from the test date, per IELTS' own policy. After that, you need to re-sit.

TOEFL iBT: approximately USD 205–250 depending on country. Also valid for 2 years from the test date, per ETS's stated policy.

Cambridge B2 First / C1 Advanced / C2 Proficiency: approximately USD 170–250 depending on country and exam centre. Does not expire — ever. A certificate issued in 2010 is still a valid Cambridge certificate today.

The validity difference is not a minor footnote. If you're taking an exam purely to meet a one-time requirement (this year's university application, an upcoming visa), the 2-year expiry of IELTS and TOEFL doesn't hurt you. But if you want a credential that represents your English level permanently — for a career, for future applications you haven't planned yet — Cambridge's lifetime validity is a real financial and practical advantage.

• IELTS: ~USD 215–250 | Valid 2 years
• TOEFL iBT: ~USD 205–250 | Valid 2 years
• Cambridge (FCE/CAE/CPE): ~USD 170–250 | Never expires

Where is each exam actually accepted?

IELTS is accepted by over 11,000 organisations worldwide (per IELTS' own published figures), including universities, employers, and immigration authorities across the UK, Australia, Canada, New Zealand, and many other countries. It is the dominant test outside the US.

TOEFL iBT is accepted by more than 12,000 universities and institutions in over 160 countries (per ETS's own published figures), with particular strength in the United States. It is less commonly accepted for immigration purposes and is rarely the required exam outside of academic contexts.

Cambridge qualifications are recognised by universities and employers across Europe and in many UK and Australian institutions. They appear on professional CVs more naturally than a band score does, because they state a CEFR level directly. However, they are not accepted as proof of English for most immigration applications — they're primarily an academic and professional credential, not an administrative one.

The decision tree: which exam fits your goal?

Rather than trying to memorise all of the above, run through this logic in order:

• 1. Immigration visa → Check the official government list of accepted tests. Almost always IELTS (often the specific UKVI or General Training version). TOEFL and Cambridge rarely qualify.
• 2. University in the US → TOEFL iBT first; confirm whether IELTS Academic is also accepted for your specific programme.
• 3. University in UK / Australia / Canada / NZ → IELTS Academic is the safest choice; Cambridge qualifications accepted at most universities too.
• 4. Professional registration (medical, nursing, law) → Check the specific body's requirements. Often IELTS Academic with specific minimum band scores per skill.
• 5. Permanent professional credential / CV → Cambridge qualifications (C1 Advanced or C2 Proficiency) are the strongest long-term investment because they never expire.
• 6. No specific requirement, just want to prove your level → Cambridge, because the CEFR-aligned certificate is the most universally legible format going forward.

What level do you actually need to be before you sit?

This question matters more than people admit. Walking into an IELTS exam at B1 when the university requires 6.5 (solidly B2) costs you the full exam fee and two months of exam stress. Cambridge exams in particular are fixed at a CEFR level — if you sit C1 Advanced at a weak B2, you will likely fail outright.

A rough readiness guide, based on Cambridge's own published target levels and IELTS band descriptors: you should be comfortably operating at B2 before sitting IELTS for a 6.5 target, and comfortably at C1 before targeting IELTS 7.0–7.5 or Cambridge C1 Advanced.

If you're not sure of your current level, that's exactly what Nivelo's free 5-minute CEFR test is for. It won't replace a full practice test, but it gives you an honest starting point — so you know whether you need six weeks of preparation or six months before booking.

One thing nobody tells you about TOEFL vs IELTS

The Speaking sections are structurally very different, and this genuinely affects which exam suits you better as a learner — not just which is accepted.

IELTS Speaking is a live 11–14 minute conversation with a human examiner, conducted in person (or by video for IELTS Online). Many candidates find this easier because it feels like a real conversation — you can build rapport, ask for clarification, recover from a stumble naturally.

TOEFL Speaking is four tasks recorded and submitted digitally — you speak into a microphone with no human on the other end. There's a strict time structure: a prompt, a short timed preparation window, then a timed response. You hear a beep and start. For candidates who freeze under mechanical pressure but speak freely in conversation, IELTS Speaking is usually a better experience. For candidates who find talking to strangers nerve-wracking, the TOEFL format can actually feel more comfortable.

This is a real, practical factor in choosing between the two — especially if your target institutions accept both.

The bottom line

There's no objectively 'best' English exam. There's the right exam for your specific goal, your destination, and your timeline.

If you need a visa: IELTS (and verify the exact version required).

If you're applying to a US university: TOEFL iBT, with IELTS Academic as a strong alternative.

If you're applying to a UK, Australian, Canadian, or NZ university: IELTS Academic is the default; Cambridge qualifications are also solid.

If you want a permanent English credential for your career: Cambridge C1 Advanced or C2 Proficiency — sit it once, have it forever.

Before you book anything, verify the requirement on the official page of the university, employer, or government body you're applying to. Requirements change. The honest answer to 'which exam do I need' is almost always: 'the one your specific institution or authority currently lists as accepted.' Everything else is preparation for that answer.

Know your level before you commit to a test date. If you haven't done that yet, start there.
