All IELTS-related research activities are co-ordinated as part of a coherent framework for ongoing test development and validation. Activities are loosely divided into areas which are the direct responsibility of Cambridge ESOL, and work which is funded and supported by IELTS Australia and British Council.
Routine analysis of test data is conducted on test materials and test takers¡¦ performance to ensure that IELTS provides valid and reliable information for score users, and that the tests are fair to test takers whatever their nationality, first language and gender. The internal research and validation agenda is complemented with work carried out through external grant-funded studies.
Comprehensive information on how IELTS is marked and what the band scores mean and how they should be interpreted can be found in Score processing, reporting and interpretation.
