Methods of Oral English Proficiency Certification

Students are certified either on the basis of their score on the Oral English Proficiency Test (OEPT) or on their performance in ENGL 62000, "Classroom Communication in ESL for International Teaching Assistants," an English as a second language course in oral communication exclusively for non-native, English-speaking TAs.

Students may also be certified via the Test of Spoken English (TSE), TOEFL iBT, International English Language Testing System, Academic (IELTS), or the Pearson Test of English (PTE), Academic. See the chart below for the scores that can be accepted for certification.
