What are the different modules for OET scoring?

The OET exam is mainly conducted to assess the proficiency of medical professionals in the English language. The test mainly consists of four modules or subtests namely:

  • Listening – to evaluate the comprehension skill of the spoken language of the candidate. Recorded audios will be played based on which the candidate will have to write the answers for the question based on it.
  • Reading – the candidate needs to give answers to the questions based on different texts related to medical topics.
  • Writing – the candidate requires to write a letter – either a referral letter or any other letters related to medical context. 
  • Speaking – The candidate must perform a role play in which they need to present the idea given in the roleplay card.

How is the OET listening and reading score calculated?

Both the OET listening and reading sections consist of three parts – A, B, and C with a total of 42 questions and 42 marks. The score is distributed in a way that Part A accounts for 24 marks, Part B for 6 marks and Part C for 12 marks. These scores are reported in terms of numeric scores ranging from 0 to 500 and grades from E to A

Out of the three parts, the A part answers are evaluated by assessors with the aid of a detailed marking guide and the B and C parts are assessed by computers. 

The minimum score required for the subtests of listening and reading may vary depending on the decision of various medical councils which are opted for, yet the test taker should obtain a score of 350 to get B grade. For scoring 350 out of 500, there should be a minimum of 30 correct answers. 

How are the OET writing and speaking scores calculated?

The writing subtest is mainly evaluated by two different assessors who are completely unaware of the score given by the other person. The test taker is required to write a letter in a medical context, and it is analyzed on the basis of 6 parameters – purpose, content, clarity, style, organization and layout and language after which the final score (0 to 500) and grade ( A – E) will be awarded accordingly.

The OET speaking subtest is conducted individually, and the interlocutor would assess the speaking skills of the test taker based on nine different criteria which are again classified into two subdivisions mainly – linguistic criteria and clinical communication criteria. The whole speaking session would be recorded for making a precise evaluation for awarding the most appropriate grade between A and E and a score between the scale of 0 and 500 to the candidate.


450 – 5008 – 9C2
350 – 4407 – 7.5C1
