OET is widely accepted by regulatory healthcare bodies, employers, and educational institutions as evidence of English proficiency for healthcare professionals. It provides a realistic and task-based assessment, ensuring that candidates can understand and communicate effectively in the workplace situations they are likely to encounter in their professional roles.

The test is recognized by various healthcare boards and councils as proof of English language proficiency, and successful completion of the OET can enhance the career prospects of healthcare professionals seeking opportunities in English-speaking countries. The test is divided into four sub-tests.
