OET writing involves writing a medical letter, such as a letter of referral or discharge. Writing needs to be formal, in a clinical tone and polite. Here are some examples that illustrate formality: 

  • Avoiding idiomatic expressions: 

Mr. Brown is back on his feet. X 

Mr. Brown has made good progress.

  • Refraining from using medical jargon if the recipient of the letter is not a medical professional: 

Mrs. Barrow will have her sutures removed. X  

Mrs. Barrow will have her stitches removed tomorrow.

  • Not using contractions but full forms instead: 

Tom hasn’t exhibited additional symptoms but will require monitoring. X 

Tom has not exhibit additional symptoms but will require monitoring.



The Language criterion in OET writing covers spelling, so assessors do focus on capitalization.
