UK mandates an English proficiency test if you are applying to any of the UK schools and come from a non-English speaking country. The UK government recognizes the following tests to justify your language ability in English: IELTS Academic, TOEFL iBT, PTE Academic, and the SELT (Secure English Language Test conducted by the UK Visas and Immigration (UKVI) authorities). These tests are mandatory for obtaining your student visa. However, students are advised to take the IELTS as this is the most widely recognised English language proficiency test by UK universities.
