Test of Spoken English (TSE): Because all financial support offers include teaching assistantships, it is important for us to be able to evaluate the spoken English proficiency of applicants for admission with financial support. Applicants who are not citizens of the US, Australia, Canada, Ireland, New Zealand, or the United Kingdom are strongly encouraged to take the TOEFL iBT, which has a Speaking component, or to submit scores on the Test of Spoken English (TSE)  offered by the Educational Testing Service.
