The main difference between IELTS and IELTS UKVI lies in their purpose. IELTS (International English Language Testing System) is widely used for academic, professional, and immigration purposes worldwide. IELTS UKVI (UK Visas and Immigration) is specifically tailored to meet UK government requirements for visa applications. While the test content, format, and scoring are identical, IELTS UKVI is conducted under stricter security measures, including video recording during the test. Choosing between the two depends on your immigration or educational goals. For UK visa-related needs, IELTS UKVI is mandatory. Always check visa or institutional requirements before booking your test.
