Admission to the Ph.D. program is available only for the fall semester. In addition to the standard undergraduate preparation in economics, students are expected to have had at least two semesters of calculus and one of linear algebra to be admitted to the Ph.D. program. The results of the Graduate Record Examination (GRE) should accompany applications for admission. Graduate College admission requirements apply. In addition, international students must submit Test of English as a Foreign Language (TOEFL) or IELTS results; if they wish to apply for a teaching assistantship, the Test of Spoken English (TSE) or completion of the speaking section of the TOEFL-iBT or IELTS is also required.
