The International English Language Testing System (IELTS) measures the language proficiency of people who want to study or work in a country where English is used as the main language of communication. It uses a nine-band scale to classify levels of proficiency, from non-user (band score 1) through to expert (band score 9).
There are two test versions of IELTS; Academic and General Training.
Academic is used for people who want to apply for higher education or professional registration. General Training aimed for non-English native language speakers migrating to an English speaking country, with the most popular countries being Australia, Canada and the UK.
Both IELTS Academic and General Training offer an effective and accurate assessment of four highly important language skills: reading, writing, listening and speaking.
