Which English Proficiency Exam Is the Strongest and Most Widely Accepted?

English proficiency tests are essential for non-native English speakers aiming to study, work, or migrate to English-speaking countries. These tests measure your ability to communicate effectively in English — and are often a mandatory requirement for visa applications, university admissions, and licensing processes (such as for international nurses or professionals).

Comparison Table

Final Verdict: Which Is the Strongest?

IELTS is the most widely accepted and versatile English exam across all sectors:

• Universities

• Immigration

• Professional licensing (nursing, etc.)

If you're a healthcare professional, OET may be a better fit due to its medical context, but IELTS is still accepted more broadly.

Summary

• Choose IELTS for global recognition, immigration, and nursing careers.

• Use TOEFL for academic purposes (especially in the U.S.).

• Opt for OET if you're a nurse or doctor applying for overseas licensure.

• Pick PTE if you want fast results and you're going to Australia, NZ, or UK.

• Consider Duolingo only if you're applying to a university that accepts it and not planning to migrate or work professionally.
