There is no best English test. There is only the test that the specific university or immigration authority reading your file will accept, and the one that suits how you perform under different marking systems.
Both halves of that sentence matter, and most people only think about the second.
Start with acceptance, not preference
Before comparing anything, do this: open the admissions page of each university on your shortlist, or the language requirements page of the immigration route you are applying for, and write down which tests they name and what minimum they require, per section.
Not the overall score. The per section minimum. A large number of applications fail on a single section falling half a band short while the overall score looks comfortable.
These lists change. A test accepted for the 2025 intake may not be on the 2027 list, and vice versa. Check the current page, dated, for each institution. If a consultant tells you a test is accepted somewhere and cannot show you that page, treat it as unverified.
The five tests, honestly
IELTS is accepted almost everywhere, for both study and immigration, in Academic and General Training versions. Speaking is with a human examiner, which suits people who do better in conversation than talking to a screen, and unsettles people who find examiners intimidating. Writing is human marked, which means it rewards actual quality and punishes memorised templates. It is the safe default when you are applying to several places at once.
TOEFL iBT is strong for the United States and widely accepted elsewhere. Its distinguishing feature is the integrated tasks, where you read something, listen to something, and then write or speak about both. People who prepare only for standalone essay writing lose marks here. Marking is a mix of automated and human.
PTE Academic is computer marked throughout, with fast results. Because the marking is algorithmic it rewards a particular kind of clear, fluent, well paced delivery and consistent structure. Some people score noticeably higher on PTE than IELTS for exactly this reason, and some score lower. It is accepted by many universities and by several immigration systems, but not universally.
CELPIP is Canadian, computer delivered, and uses Canadian English throughout. If your target is Canadian immigration and you are comfortable with Canadian vocabulary and register, it is worth considering against IELTS General. It is not widely accepted outside Canada.
Duolingo English Test is by a distance the cheapest and quickest, taken at home, with results in a couple of days. Acceptance is the catch: a large and growing number of universities accept it, and a large number still do not, and immigration authorities are more conservative than universities here. It is an excellent option when your specific shortlist accepts it, and a wasted fee when it does not.
The comparison that actually helps
| Test | Marking | Result speed | Where it is strongest | Main risk |
|---|---|---|---|---|
| IELTS | Human speaking, human writing | About two weeks, faster on computer delivered | Accepted almost everywhere | Nothing structural, it is the default |
| TOEFL iBT | Mixed automated and human | About one to two weeks | United States, widely accepted | Integrated tasks catch people out |
| PTE Academic | Fully automated | Often within days | Fast turnaround, computer marking | Not accepted everywhere |
| CELPIP | Fully automated | About a week | Canadian immigration | Little use outside Canada |
| Duolingo | Automated, at home | A couple of days | Cost and speed | Acceptance is uneven |
Fees vary by country and change annually, so check the current fee on the test provider's own India page rather than any figure quoted here or elsewhere.
Choosing between them, practically
Ask four questions in this order.
Does my whole shortlist accept it? If one test covers every institution and route you care about, that usually settles it. A second test fee is worse than a slightly suboptimal first choice.
Am I better with a human or an algorithm? People who are fluent, well paced and slightly mechanical tend to do well on computer marked tests. People who are expressive, occasionally hesitant, and good at genuinely engaging with a question tend to do better with a human examiner. Sit one free practice test of each type before deciding. This is the single most useful hour you can spend.
How fast do I need the result? If an application deadline is four weeks away, result turnaround is a real constraint and it is worth weighing.
What does a retake cost me? Not just the fee. Some routes will not wait.
Preparation, in plain terms
Whichever test you pick, the same things are true.
Your score is mostly your existing English, and preparation moves it by a limited amount. Someone at a genuine band 6 does not reach band 8 in three weeks, and anyone selling that is selling something else. What preparation reliably does is stop you losing marks you should not lose: misreading the task, mismanaging the time, answering a different question than the one asked, or writing 340 words when the task wanted 250.
For most people the largest single gain is in writing, because writing is where the format is least like anything you do at work, and where the marking criteria are published and specific. Read the public band descriptors for your test. They tell you exactly what the examiner is looking for.
Speaking improves with practice against another person, not with more theory. If you are preparing alone, record yourself and listen back, which is uncomfortable and effective.
Before you book
- Confirm the test on each target institution's own current page.
- Note the per section minimum, not just the overall.
- Check the validity period, and count forward to your intended application date.
- Sit one free practice test of a human marked format and one of a computer marked format.
- Then book, and book early enough that one retake still fits inside your timeline.
Our language coaching pages set out the format, the hours, the batch size and the price for each test, and you can enrol without speaking to anyone.
