The Occupational English Test (also known as OET®) is an English language test that assesses the English language proficiency of overseas-trained healthcare professionals seeking to register and practise in an English-speaking country.
The test is recognised by organisations around the world, including for migration and licensing in Australia, New Zealand, the USA and the UK.

OET was designed in the late 1980s by Professor Tim McNamara, under the guidance of the Australian National Office for Overseas Skills Recognition (NOOSR), which administered the test at that time. The test has been researched and developed continuously since then to ensure that it has kept up with current theory and practice in language assessment. This work has been done by the University of Melbourne's Language Testing Research Centre and by Cambridge Assessment English.

Since March 2013 the test has been owned by Cambridge Boxhill Language Assessment Unit Trust (CBLA), a joint venture between Cambridge Assessment English (Aus) and Box Hill Institute.
