Embarking on a journey towards academic or professional success often involves proving your English language proficiency. For healthcare professionals in Cambodia, the two prominent tests to consider are the Occupational English Test (OET) and the International English Language Testing System (IELTS).

But how do these tests compare in terms of scoring and result interpretation? This article provides a comprehensive comparison of the OET and IELTS scoring systems to help you make an informed decision about which test best suits your needs.

Understanding OET exam scores

The OET English test is specifically designed for healthcare professionals and assesses your English language proficiency across four key skills: Listening, Reading, Writing, and Speaking. Each section is scored on a scale from 0 to 500 in increments of 10, with scores being reported as grades ranging from A to E. Here is a breakdown of the OET scoring system:

  • Grade A (450-500): Indicates a very high level of proficiency. Test-takers with this score can communicate very effectively with patients and healthcare professionals.

  • Grade B (350-440): Represents a high level of proficiency, suitable for working in healthcare settings.

  • Grade C+ (300-340): Demonstrates a good level of English that may require some improvement.

  • Grade C (200-290): Indicates moderate proficiency, suitable for limited use in healthcare contexts.

  • Grade D (100-190): Reflects a low level of proficiency, not suitable for professional registration.

  • Grade E (0-90): Indicates very limited proficiency.

OET exam scores are valid for two years, giving test-takers ample time to use their results for professional registration or migration purposes. The test is designed to replicate real healthcare scenarios, making the OET highly relevant for those in the medical field.

Each OET exam format assesses specific skills essential for effective communication in healthcare environments:

OET Listening

In the OET Listening section, test-takers listen to healthcare-related dialogues and monologues. The exam is divided into three parts, each designed to evaluate your ability to understand and respond to a variety of healthcare-related audio materials. Scores are awarded based on the ability to grasp specific information and context.

OET Reading

The OET Reading section is divided into three parts: Part A tests your ability to skim and scan short texts for specific information; Part B assesses understanding of short workplace texts; and Part C evaluates the comprehension of longer healthcare-related passages. It involves healthcare-related texts and assesses your ability to understand and interpret written material.

OET Writing

The OET Writing exam requires test-takers to produce formal letters based on a typical workplace scenario. Scores are based on the ability to convey information clearly and accurately, using appropriate tone and register. Test-takers must demonstrate their ability to organise content logically, use precise language, and adhere to professional writing standards.

OET Speaking

The OET Speaking section involves role-plays based on healthcare scenarios, with scoring focused on communication effectiveness, clarity, and the ability to convey information appropriately. This section assesses your ability to engage in meaningful conversations, provide clear instructions, and respond empathetically to patient concerns.
