The International English Language Testing System (IELTS) assesses the level of English of non-native speakers who need to use English in an Academic or Professional context, or who needs English for a visa application.
IELTS is not a pass/fail exam. Each module of the test is graded separately as a 'BandScore'.
The module scores are then added together to provide an overall Band Score. Band scores range from 1 (=non user) to 9 (=expert user). Most universities and institutions of Higher Education will ask for anoverall Band score (generally between 6 - 7.5).
