The International English Olympiad (IEO) is a global English-language test intended to be a part of the standard-bearer of the international English-language academic world. It is an exam that you can take to prove your linguistic knowledge and gain access to advanced study programs at leading universities around the world.

In the test, candidates will be required to show their word knowledge and also their reading, writing, and speaking abilities. They will be tested on their ability to understand a text and also their ability to express that understanding in writing and speech. 

The IEO is divided into two parts: an oraleffice test and a written expression test.
