OET Scoring: Your Guide Simplified!

Understanding OET scoring is an important step for achieving a high score.  

This article from E2Language outlines the four language skills assessed for OET scoring and provides an explanation of the grading scale and exam procedure. 

OET Language Skills:

OET Scoring

The OET assess the four main language skills shown below:

Skill Area:Content:Demonstrates their ability to:
ListeningCommon to all professionsFollow and understand a range of health-related spoken materials such as patient consultations and lectures
ReadingCommon to all professionsRead and understand different types of text on health-related subjects
WritingProfession SpecificWrite a letter in a clear and accurate way which is relevant for the reader
SpeakingProfession SpecificEffectively communicate in a real-life context through the use of role-plays

According to the OET Preparation Support Pack

Each skill area is referred to as a “sub-test” in the OET. You will need to become familiar with each skill area, including the number of tasks and how they test your skills.

The Grading Scale

Your scores will be given to you on a scale from A (highest) to E (lowest).

The following table describes each grade level:

Grade:Description of Ability:
AVery high level of performance
BHigh level of performance. i.e. able to use English with fluency and accuracy adequate for professional needs
CGood level of performance; however, not acceptable to a range of health and medical councils
DModerate level of performance: requires improvement
ELow level of performance: requires considerable improvement

According to the OET FAQS

In other words, you must score a B or above in all sub-tests in order to “prove” that your English ability is adequate for professional needs.

Exam Grading and Procedure

So, who grades the exam and what’s the procedure?

Listening and Reading

The entire Listening sub-test and Part A of Reading are scored by trained OET assessors on-site. All answer packets are randomly assigned to avoid possible conflict of interest.

These assessors score your answer booklet using a detailed guide. It specifies exactly which answers receive marks and how those scores are counted.

This guide helps assessors decide whether the test taker provided enough correct responses to be given the available marks (or mark). Every assessor is monitored and scores within data entry are double checked for accuracy.

Part B of Reading is automatically machine graded when the answers are scanned into the computer.

Writing and Speaking

OET scoring
Practice recording your voice and typing on the computer as this will simulate real test conditions!

Writing and Speaking sub-tests are graded by at least two of the OET assessors. Similar to the Listening and Reading sections, your audio files and scripts will be given at random.

These assessors are monitored and the scores they give are adjusted depending on if they are a strict or lenient grader.

In order to ensure accurate scoring, the OET centre only accepts marks if both of the assessors award the same grade to a given performance, audio file or script.

If the two assessors award different scores, your piece will be passed on to at least one senior OET assessor (who has not previously been involved in your marking) to decide your grade.
