Do I need to take IELTS or any other English proficiency test like TOEFL or PTE given my 15 years of work experience?

It depends. Some universities may waive English proficiency tests like IELTS, TOEFL, or PTE for applicants with extensive work experience in an English-speaking environment, but this is not guaranteed and varies by institution and program.

- Eligibility for a waiver often requires proof that your professional role involved daily use of English, was in a majority English-speaking country, and ended within the last two years.
- Each university sets its own criteria and documentation requirements for waivers.

You should check the specific English proficiency policies of your target universities.
