English proficiency tests are the most important and common requirement for studying in the UK.  All universities and courses require international students to prove their English proficiency by submitting test scores such as the International English Language Testing System or IELTS, the Test of English as a Foreign Language (TOEFL) and the Pearson Test of English Academic (PTE Academic).  While these are some of the common English language tests for admission, students can also take Duolingo English tests, Cambridge Certificate of English Proficiency (CPE) and Trinity Secure English Language Tests (SELT).
