The IELTS partners report yearly on the distribution of scores achieved by various groups of test takers and reliability estimates for some of the modules. This information helps researchers and teachers understand the performance of the test and how test takers perform in particular countries or regions.
This data shows overall band scores for Academic and General Training test takers in 2017 together with scores for individual skills according to a variety of classifications.
Each year, multiple versions of each of the six IELTS components (Listening, Academic Reading, General Training Reading, Academic Writing, General Training Writing, and Speaking) are released for use by centres testing IELTS test takers. These tables show reliability estimates for some of the components used in 2017.
