IELTS stands for International English Language Testing System, a globally recognized assessment designed to evaluate the English language proficiency of individuals who wish to study, work, or migrate to English-speaking countries. It is considered essential because it measures key communication skills—listening, reading, writing, and speaking—ensuring that candidates can effectively function in academic and professional environments. Accepted by thousands of universities, employers, and immigration authorities worldwide, IELTS serves as a reliable indicator of one’s ability to use English in real-life contexts, making it a critical step for those pursuing international education or career opportunities.
