It is not necessary that applicants have an undergraduate major in zoology. However the following academic background is required:

24 semester hours (or equivalent) in courses covering the basic principles of zoology (including animal diversity, ecology, and evolution),
9 credit hours of physical sciences (physics, chemistry, soil science, geology at least 2 disciplines must be represented),
one year of college mathematics including college algebra and trigonometry (calculus and statistics are also desirable),
be within 9 credit hours of meeting class requirements for a Certified Wildlife Biologist ,
an undergraduate grade point average of at least 3.0 (A = 4.0).
Once a student's application file is complete (including all letters of recommendation, transcripts, and GRE scores), it is reviewed by several Zoology faculty members. During this review, individual faculty members will indicate their willingness to supervise the applicant. Students who meet the requirements for admission, and for whom the Department has identified both an advisor and a stipend, will be notified in writing of their admission to the program and provided with all necessary information to initiate enrollment. In the interests of professional development, the Zoology Department strongly discourages students who have obtained Zoology B.A./B.S and M.S. degrees at SIUC from applying to the Ph.D. program.
