The Department of Computer Science and Operations Research offers the Master of Science (M.S.) and Doctor of Philosophy (Ph.D.) degrees in Computer Science. Graduate course work in Operations Research is offered and may be used to provide an operations research concentration to either program. In addition to the minimum Graduate School requirements, the following items are required for all Computer Science applicants seeking an advanced degree. For the Master of Science program, the applicant must have a bachelor’s degree from an educational institution of recognized standing. Admission to the program is competitive; the following minimum requirements are necessary but are not sufficient for automatic admission: the applicant must show, by a combination of educational background, academic performance, and work experience, the potential to succeed in advanced study and research in computer science. Minimum preparation usually includes the ability to program in one or more modern, commonly used high-level languages; and experience in using data structures such as linked lists and binary trees. Minimum preparation for unconditional admission to the master's program would normally include courses in computer science principles and theory equivalent to the NDSU courses; the applicant for the Master of Science must have a cumulative grade point average (GPA) in all previous courses of at least 3.0 (out of 4.0) or equivalent to attain full standing; the applicant for the Computer Science M.S. degree program must have a score above the median (50th percentile) for the quantitative reasoning portion of the GRE exam; international students are welcome to apply. They must submit TOEFL, IELTS, or PTE Academic score. Minimum requirements are: TOEFL score of at least 550 (paper based) or 79 (internet based); IELTS score of at least 6.5; PTE Academic score of at least 53. Eligibility for a teaching or tutoring assistantship requires the following additional requirements: TOEFL score minimum overall of 79, with minimum of 19 speaking, and minimum of 21 writing; IELTS score minimum overall of 6.5, with a minimum of 5.5 speaking and minimum of 6.0 writing; PTE Academic score minimum overall of 53, with a minimum of 51 speaking and minimum of 56 writing. For the Doctor of Philosophy, the applicant must have at least a four-year bachelor's degree, or a master's degree in computer science. In some cases, students with a degree in a closely related area may be considered, provided the course work includes exposure to the skills listed under M.S. above. Students with only a bachelor's degree should have substantial computer science experience, whether acquired through course work or professional experience; admission to the program is competitive, and requirements for admission to this program are more rigorous than for admission to the M.S. program. The applicant for Computer Science Ph.D. degree program must have a GRE score above the median (50th percentile) for the quantitative reasoning portion. The admissions committee will evaluate the applicant's overall academic record, as well as any relevant employment and professional experience. Of particular importance is evidence of the applicant's potential for scholarship and independent research at the Ph.D. level. International students are welcome. English Language requirements are the same as for the Computer Science Master of Science degree. Assistantships are available to selected graduate students. Teaching one section of a lower division service course requires 10 hours of work per week and qualifies the student for a waiver of graduate tuition. Other assistantships that provide a stipend and tuition waiver include research assistantships, which involve assisting faculty with their research, and graduate service assistantships, which involve tutoring, grading or computer-related work with faculty members or organizations on campus. Related prior experience increases the likelihood of a teaching or tutoring assistantship being awarded. For all assistantships, a student's chances are greater after they have been at NDSU one or two semesters. The department offers a tuition waiver only to students who are awarded an assistantship. There is a scholarship program that includes a tuition waiver, administered by the Dean of the Graduate School. Students should contact the Graduate School for application forms. The graduate admissions committee reviews all applications at the time of acceptance and considers them for any available assistantship positions within the department. If an assistantship is not offered at time of admission, accepted students can then fill out an application on the Computer Science website for later consideration.
