The application clearly states:
English Language Proficiency Requirement
All international applicants must demonstrate proficiency in the English language. If you do not qualify for a waiver, you must report a valid TOEFL or IELTS score.
While we do not require an official test score at the time of application, an official TOEFL or IELTS score report must be reported to Cornell Tech Admissions prior to matriculation.
Please note that TOEFL and IELTS scores remain valid for two years.
Cornell Tech’s TOEFL school code is 2098. Cornell Tech’s IELTS Recognizing Organization (RO) name is “Cornell University Cornell Tech.”
**The English language proficiency requirement may be waived if the applicant meets at least one of these criteria:
Is a citizen or permanent resident of the United States, or a citizen of the United Kingdom, Ireland, Australia, New Zealand or Canada (except Quebec).
At the time you enroll at Cornell, you have studied in full-time status for at least two academic years within the last five years in the United States, the United Kingdom, Ireland, Australia, or New Zealand, or with English language instruction in Canada or South Africa. Even if English was the language of instruction at your school, if you did not study in one of these countries you are not exempt from the requirement. You must submit a transcript that shows you attended college in one of the approved locations, and that your academic program was at least two years in length.
