The IELTS band scores range from 1 to 9.
Candidates receive an overall score as well as a score for each skill.
The reading and listening are scored out of a maximum of 40 and the result is converted into a band score between 1 and 9.
The speaking and writing tests are marked by examiners in four areas of competency and those four areas are averaged to get a single band score. For example, a candidate who is awarded 7/7/6/6 in each area of competency in the speaking test will receive a 6.5 overall score.
