Four tests, one goal: prove your English for a university abroad. IELTS, TOEFL iBT, PTE Academic and the Duolingo English Test are used by institutions in different markets, but acceptance is never universal. They differ sharply in format, marking and result service, and the right choice depends on the exact institution and visa route as much as on your English.
Choose by your situation:
- UK visa route → IELTS (for UKVI) or PTE Academic UKVI — check the exact SELT requirement for your route.
- You want the fastest result → PTE Academic (typically within two business days) or DET (typically 48 hours).
- You test better speaking to a person than a microphone → IELTS, the only one of the four with a live human examiner.
- Budget-first and testing from home → DET, but verify your specific university and visa route accept it before booking.
- Undecided → confirm which tests your target institutions accept, then pick the format that suits how you perform under time pressure.
The four at a glance
- IELTS Academic — 4 skills, 2h40m for Listening/Reading/Writing plus an 11-14 minute Speaking test, band 0-9. Speaking is with a human examiner; delivery options vary by market. Full IELTS guide.
- TOEFL iBT — 4 skills, ~90 minutes of base testing (allow about 2 hours for the appointment) after the 2026 overhaul, scored on a new 1-6 band scale, with a transitional comparable overall 0-120 score for two years after Jan 2026. Adaptive sections. Full TOEFL guide.
- PTE Academic — 3 modules, ~2 hours, AI-led scoring (with human expert review on selected responses) on a 10-90 scale, with results typically within two business days. Full PTE guide.
- Duolingo English Test — an at-home, adaptive test on a 10-160 scale, with results typically in 48 hours. Institution and visa acceptance must be checked separately. Full DET guide.
Human vs AI marking — the real dividing line
This distinction shapes your whole preparation:
- IELTS uses human examiners for Speaking and Writing. Speaking includes Fluency and Coherence, Pronunciation, Lexical Resource and Grammatical Range and Accuracy; Writing uses Task Achievement/Response, Coherence and Cohesion, Lexical Resource and Grammatical Range and Accuracy.
- PTE combines AI scoring and selected human review. All question types are AI-scored; seven task types also receive human double marking for content, and unusual responses may be reviewed. Pronunciation and oral fluency remain machine-scored. Candidates who dislike a live interview may still prefer speaking into a microphone.
- DET uses automated scoring, while TOEFL records Speaking and Writing responses for scoring rather than using a live interview. Check each provider's current scoring guide instead of choosing from the vague label “AI test”.
Cost and speed
Fees vary by country, tax and service option, so compare the live booking pages in your market rather than a copied global price. DET and PTE usually advertise fast standard results; IELTS and TOEFL turnaround varies by delivery mode and service. If a deadline is close, result speed matters only after both the institution and visa route accept that exact test version.
Compare the four by dimension
- Speaking interaction: IELTS uses a human examiner. TOEFL, PTE and DET collect spoken responses through a computer interface.
- Delivery: IELTS availability varies by market and mode; TOEFL offers authorised-centre and monitored home options; PTE is delivered in test centres; DET is taken remotely under its security rules.
- Scoring scale: IELTS reports 0-9 bands; TOEFL reports 1-6 section/overall scores with a transitional comparable overall score; PTE reports 10-90; DET reports 10-160.
- Task structure: IELTS separates the four skills clearly. TOEFL and PTE include tasks that combine or transfer skills. DET is adaptive and shorter.
- Best evidence before choosing: the institution's accepted-test page, the visa authority's current rule, the provider's official format page and your own diagnostic performance.
This section compares test experience. For destination-specific acceptance, use the separate country and visa guide; keeping those intents separate prevents a format preference from being mistaken for immigration advice.
Choose by your test-day profile
Once acceptance is confirmed, match the format to how you actually perform:
- Choose IELTS if you communicate naturally with a person and prefer four clearly separated skill scores. You must be comfortable with a live Speaking interview and examiner-scored writing.
- Choose TOEFL if you are comfortable with academic campus material, taking notes while listening and recording spoken responses into a microphone. Its integrated tasks reward moving information from one skill into another.
- Choose PTE if you prefer a fully computer-based appointment, fast result delivery and many short task types. You need consistent microphone technique and must prepare to the current scoring criteria rather than memorised templates.
- Choose DET if your target institution and visa route explicitly accept it, you need an at-home test and the shorter adaptive format suits you. Test-room flexibility is irrelevant if the destination will not accept the result.
Do not choose from one strength alone. A candidate may love PTE's microphone format but need IELTS for a particular regulator; another may prefer DET's convenience but find that their visa route requires an approved secure-centre test.
Acceptance is a gate, not a comparison
Before comparing format, remove every test that your specific institutions or visa route do not accept. This article does not reproduce destination rules; accepted test versions can differ, so use the separate country and visa guide and then verify the receiving authority's current page.
How to choose, in order
- List your target universities' accepted tests and minimum scores — from their official pages, not forums.
- Check your visa route's accepted tests — remove any test or test version not named by the current rule.
- Match to your strengths — live interview vs machine, essay vs short tasks, adaptive vs fixed.
- Then weigh cost and speed among the tests that clear steps 1-3.
Write the decision on one page before booking: target institutions, visa authority, minimum score, deadline, accepted test versions, result turnaround and your strongest/weakest format. If any row is unknown, the decision is not ready.
Quick answers
Which test is easiest? None is universally easiest. The easiest valid option is the one accepted for your destination whose format best matches your speaking, writing, listening and test-day preferences.
Can I choose only by university acceptance? No. Admission acceptance and visa acceptance are separate checks. Confirm both before paying.
Which test gives results fastest? PTE and DET are usually the fast-result options, but current service levels can change. Verify the provider's official result page when booking.
Should price decide the test? Only after acceptance and score requirements. A cheaper rejected result is the most expensive outcome.
Can I convert one provider's score into a guaranteed minimum for another? No. Concordance tables describe score relationships; institutions still publish their own accepted tests and minimums. Use the exact requirement shown by the receiving organisation.
Whatever you choose, practise the real format under real timing and compare diagnostic results before booking.
