Methods of Oral English Proficiency Certification

Students may be eligible for certification of oral English proficiency by one of these means: 

• Their score on the TOEFL iBT Speaking section;
• Their score on the IELTS Speaking section;
• Their score on Purdue’s Oral English Proficiency Test (OEPT);
• Their performance in ENGL 620, "Classroom Communication in ESL for International Teaching Assistants," an English language course in oral communication exclusively for prospective TAs whose first language is not English. Only grad students who have scored 40 or 45 on the OEPT are eligible for the course.
