This test is designed to assess Reading, Writing, and Speaking skills to provide a full picture of overall English proficiency. It is accepted by both Undergraduate and Graduate Admissions at the University of Arizona, whether you are applying to an in-person degree in Tucson, or you are going to study online or at a micro-campus in a foreign country.
Note that if you have already been admitted to the University of Arizona, and you are only seeking to demonstrate your spoken proficiency in order to be considered for a graduate teaching assistant (TA) position, you must register to take CEPT OPI, and not CEPT Full Academic.
