Coursework
The program requires a minimum of 60 hours of coursework excluding internship and the dissertation credit beyond the bachelor's degree or 30 hours of such coursework after the master's degree. At least 15 hours of the coursework must be earned at the 700 level or above, excluding the dissertation and the internship credits. These hours are distributed among core courses and elective courses. The minimum hours that are required in each category is specified in parentheses. An advisor will assist a student in the selection of the courses. Courses in which a student earns or has earned a grade below C (2.0) do not count toward meeting any graduate degree requirements.
Students who enter with a bachelor's degree and have satisfied any of the course requirements prior to entering the program may be excused from that course requirement. For this to be approved, the student must complete the Course Requirement Waiver Form supplied by the department. However, the required total 75 credit hours will not be affected.
For students who enter the program with a master's degree, up to 30 hours of relevant graduate coursework may be counted towards the program requirements, in consultation with an academic advisor. The required minimum number of 45 credit hours will not be affected.
For graduate students who transfer from a comparable graduate program, up to 15 hours of the relevant graduate work may be transferred, in consultation with an academic advisor. The transferred hours will be counted towards the required total 75 credit hours.

Qualifying Examination
In the Ph.D. qualifying examinations, students are expected to demonstrate a broad knowledge of the topics and be able to integrate concepts and explain them at an appropriate level. Prior to conducting dissertation research work, a Ph.D. student must pass two qualifying exams in the areas of 1) Theoretical Statistics and 2) Applied Statistics.
Full-time students entering with a bachelor’s degree must pass both examinations by the end of their seventh semester counting from the semester they enter the Ph.D. program. If a student takes a leave of absence, then those semesters do not count towards the seven semesters.
Full-time students entering with a master’s degree must pass both examinations by the end of their fifth semester counting from the semester they enter the Ph.D. program. If a student takes a leave of absence, then those semesters do not count towards the five semesters.
A maximum of two attempts in each area are allowed. A second failure in one area eliminates the student from the Ph.D. Program.
Internship (3 hours)
Students are required to take three (3) hours of internship. Students can choose either a teaching internship or a non-teaching professional internship. Students must earn credits for the internship by registering for STA 794 for the teaching internship or STA 795 for the non-teaching professional internship. The internship can only be taken after passing all the qualifying examinations.
For students who plan to take a teaching internship, prior to seeking a faculty teaching internship supervisor, the student is required to consult with his/her academic advisor. Teaching internship courses are at the undergraduate level, generally at the 400 level or below offered in the Department of Statistics, Actuarial and Data Sciences.
For students who plan to take a non-teaching professional internship, the student must consult with the internship faculty coordinator to arrange their internship with an external company (agency) and must complete a written contract with the company (agency) prior to registering for the non-teaching professional internship.
