The Occupational English Test (OET) is a specialized English language proficiency test designed for healthcare professionals. 

Its primary goal is to evaluate the ability of candidates to communicate effectively in medical contexts. Below is a detailed overview of the OET test structure, purpose, and recognition.

Purpose and Target Audience

• Designed for Healthcare Professionals: OET assesses English language skills in real-world medical scenarios, making it ideal for doctors, nurses, pharmacists, physiotherapists, and other allied health professionals.

• Global Recognition: The test is accepted by regulatory healthcare boards and councils in countries such as Australia, New Zealand, the UK, the USA, Ireland, Canada, and more. It is also recognized for migration purposes by immigration authorities in several nations.

Structure of the Test

The OET consists of four sub-tests that assess different language skills. Each sub-test is tailored to healthcare scenarios:

Detailed Breakdown of Sub-Tests
