Other Requirements

  • Examinations: 
    • Master's Examination: Students admitted to the PhD program without a previous MS degree in statistics, mathematics, or related field must earn a high pass on the department's master's examination in statistics by the end of the second year in the program.
    • Preliminary Examinations: Students must pass two written preliminary exams, each in a selected core topical area. These examinations are administered in accordance with the Graduation College rules, as stated in the graduate and professional catalog, and require the student to be enrolled at the time of the exam.
