The International English Language Testing System (IELTS) is one of the world's leading English proficiency exams, trusted by over 11,000 institutions across more than 140 countries, including top destinations like the USA, UK, Canada, Australia, and New Zealand. The test is scored on a band scale from 1.0 to 9.0, with 9.0 representing expert-level English skills. For admission purposes, most universities require a minimum score of 6.0 for undergraduate programs and between 6.0 and 7.0 for graduate studies. IELTS offers two formats: Academic, for those pursuing higher education or professional registration, and General Training, for migration, work experience, or non-academic training purposes.
