The most preferred English language test to study abroad is the IELTS (International English Language Testing System). It is widely accepted by universities, colleges, and immigration authorities in countries like the UK, Australia, Canada, and New Zealand. Many institutions in the USA also accept IELTS scores.

Other popular English language tests include:

- TOEFL (Test of English as a Foreign Language): Commonly accepted in the USA and Canada, but also recognized by institutions worldwide.
- PTE Academic (Pearson Test of English): Increasingly accepted in Australia, the UK, and other countries.
- Duolingo English Test: Accepted by some universities, especially after the COVID-19 pandemic, but not as widely as IELTS or TOEFL.

Which test should you choose?
- IELTS is the safest choice if you are applying to multiple countries or want a test that is accepted almost everywhere.
- Some universities and countries may have a preference, so it’s important to check the specific requirements of your chosen institutions.
