Most universities require proof of English language proficiency for MBA programs in Europe. Commonly accepted tests include IELTS, TOEFL, and PTE Academic. These tests show that international students can read, write, speak, and understand English effectively during their studies. However, some universities may waive the IELTS requirement if the student has completed previous education in English or studied at an English-medium institution. Requirements may vary depending on the university and program, so students should always check the specific language requirements before applying.
