The Master of Science program in microbiology requires a minimum of 30 s.h. of graduate credit. Students must maintain a cumulative g.p.a. of at least 2.80 to earn the degree. They are required to earn a minimum of 12 s.h. in microbiology courses chosen from three of the department's six subdisciplines. They may substitute a course they have already taken (at the University of Iowa or elsewhere) for a course requirement, with the M.S. advisory committee's approval.

Additional course requirements depend on students' interests and the advice of the examining committee. Students must write a thesis based on their own research and defend it satisfactorily in an oral examination. No more than 9 s.h. of credit for thesis research may be counted toward the 30 s.h. required for the degree.

Applicants must meet the admission requirements of the Graduate College; see the Manual of Rules and Regulations of the Graduate College on the Graduate College website. They should have a cumulative g.p.a. of at least 3.00 and must have completed courses in biology, chemistry (inorganic and organic), mathematics including calculus, and physics. Those admitted with deficiencies must complete the relevant course work during their first year of graduate study. Admission is determined through a review and formal vote by the faculty.

Preference is given to students applying to the Ph.D. program.
