The Occupational English Test (OET) is an international language test specifically designed to assess the language communication skills of healthcare professionals who seek to register and practise in an English-speaking environment. Distinct versions of the test are available for twelve healthcare professions. OET is recognised by regulatory healthcare bodies and councils in the UK, Australia, New Zealand, Singapore, Dubai and Namibia as well as by the Australian Department of Immigration and Border Protection and Immigration New Zealand for a number of visa categories.

Originally developed in the 1980s, OET is backed by over 30 years of research by the Language Testing Research Centre at the University of Melbourne, and has gone through a continuous cycle of research, validation and evaluation to ensure it remains relevant and fit for purpose. In 2013, ownership of the test passed to Cambridge Boxhill Language Assessment (CBLA).
