English test waiver
Khalifa University requires IELTS Academic 6.0 or TOEFL iBT 79 for undergraduate admission, and says meeting the English requirement is mandatory to enrol; EmSAT is not mandatory but valid scores are considered. Master's and PhD applicants need IELTS Academic 6.5 overall or TOEFL iBT 91 taken at a test centre (the Home Edition is not accepted), within the 24 months before applying. Graduate applicants are exempt if they are native English speakers from countries such as the United States, United Kingdom, Canada, Australia or New Zealand, or graduates of an English-medium institution who can show IELTS 6.0 or TOEFL iBT 79 at the time of admission.
