IELTS - What is the IELTS Test for?
The IELTS Test is quite different from other English language tests available. The testing philosophy behind a number of English tests is to show what people know about English rather than show what they can do in English. The assumption is, for instance, that if people know a lot about grammar and have a good vocabulary, they must be able to use English well. Of course, this is not necessarily the case. Many students are extremely good at grammar and have a good range of vocabulary, but they are not very good at communication in the language.
Unlike may tests, the IELTS Test does not have grammar questions or questions specifically on vocabulary. Instead, the IELTS Test has a number of 'tasks' with specific objectives. In the test, your goal is to achieve the objective. This means that you answer questions about a dialogue or a monologue that you listen to. You have to read a number of texts and answer questions based on the text. You will have to write essays and you will have to speak to a native English speaker. As you can see, the IELTS Test is very much a test of what you can do in English, rather than what you know.
