What is a band score?
You cannot pass or fail IELTS. The test is scored on a band score. A band is a level of ability. In each section, you can score anywhere from a band of 0(nonuser) to a band of 9(expert user). In the listening and reading modules, a mark is given for each correct answer. This number is then converted into a band, with a conversion table. Overall scores are an average of all four sections and can be given in whole or half bands.
