Ph.D.: Operations & Management Science Concentration
This program will prepare you for a career in business, industry, or government using expertise gained in applied problem solving and data analysis. You will receive rigorous fundamental training in statistics, research methods, mathematics, and operations research, followed by theoretical study within your field of interest. All students are expected to produce publishable research for peer-reviewed journals prior to graduation.
A minimum admissions index score of 1250 is required to be considered for admission. The index is based on the formula GPA x 200 + GMAT (and a TOEFL of 580 for ESL students). There is not a minimum GMAT score requirement. However, successful candidates typically exceed 650.
We prefer the GMAT, but we do accept the GRE test as a substitute. In either case, the exam must have been taken within 5 years of the time of application to WSU. A GMAT conversion will be applied to the GRE score submitted by applicants who take the GRE in lieu of the GMAT. The Educational Testing Service (ETS) provides a conversion chart. The converted GRE score will then be applied to the Carson College of Business admissions index score in the same manner as a standard GMAT score.
Most successful applicants to the program have attained, at minimum:
- Bachelor’s degree from a four-year accredited university
- 3.25 GPA
- 600 GMAT score
As an entering Ph.D. student, you should be competent in math and business (accounting, economics, finance, management, marketing, operations management), and have adequate computer skills and a good command of the English language. If you are deficient in any of these areas, additional coursework and preparation (beyond the major course of study) may be required. Your advisory committee will determine those requirements.
Ph.D. Professional Development Seminar
Students will take the one-credit college-wide professional development colloquium (BA 598) during their first year or as soon as possible when approved by the area coordinator.
Ph.D. Teaching Course
Students will take the 3-credit BA 596 teaching course, ideally in the fall of their second year.

Additional Ph.D. Coursework
A minimum of 9 credit hours of coursework approved for graduate credit must be designated and approved by the student’s Ph.D. committee.
Ph.D. Research Credit Requirements
Minimum of 32 Credits
In addition to the research tool and field requirements, the Ph.D. in Business requires an additional body of research credits in preparation and development of the final dissertation. A minimum of 32 (800-level) research credits hours is required.
In addition to the CCB progress requirements, students are required to pass a qualifying exam. The exam is typically taken in June after the first year of study. Only one retake is allowed, typically in the subsequent August. Students may be able to earn a waiver from certain portions of the exam, depending on their performance in Stat 443, Stat 556, Math 464, and MgtOp 470.
