The IETLS certification was originally called the English Language Testing Service (ELTS) and was launched in 1980 by Cambridge English Language Assessment (formerly known as UCLES) and the British Council. From the beginning, it featured an original format that reflected changes in the teaching and learning of the English language. It reflected the growth of communicative language teaching and English for Specific Purposes. Individual test questions were designed to reflect the demands of real-world English use.
During the 1980s, candidate numbers were very low (around 4,000 in 1981 and 10,000 in 1985) due to problems in the administration of the whole test. For this reason, the ELTS Revision Project was created to modify the testing and improve its administration. The International Development Program of Australian Universities and Colleges (IDP), now known as IDP: IELTS Australia, was invited to join with Cambridge English Language Assessment and the British Council.
IELTS certification has been in the making since 1980. Back then, candidates took 2 non-specialised modules, Listening and Speaking, and 2 specialised modules, Reading and Writing. Individual candidate numbers have grown at an average of 15% per year and in 1995 IELTS was taken by 43,000 candidates at 210 test centres around the world.
The IELTS Academic and IELTS General Training tests are designed to cover a wide range of language skills from beginners to experts in the English language. The Academic version is for candidates who have chosen to study a tertiary level education in an English-speaking country or need to gain confirmation of their professional language skills. The General Training version is for candidates who have decided to work, train and study at a secondary level of education, work for international companies or migrate to an English-speaking country.
The difference between the Academic and General Training versions is in the content and the purpose of each task. All other features such as timing, length of written answers and assessments remain the same.
