In addition to the CSULB prerequisites for entrance into a graduate program stated in the University Catalog under Graduate Degree Information, the Biological Sciences Department requires the following:

A faculty member in the department who agrees in writing to serve as the thesis advisor to the student prior to their acceptance into the M.S. program. Applicants are encouraged to contact Biology faculty members to inquire about being their thesis advisor and openings in their lab. It is beneficial to do this before submitting your departmental application (search the list of research faculty for potential advisors),
A bachelor's degree in the biological or related sciences from an accredited institution. Students with alternative undergraduate degrees or minors in the Biological Sciences will be considered, but should email the Graduate Advisor or the Graduate Services Coordinator,
An undergraduate GPA of at least 3.0 in all completed science and mathematics courses OR a GPA of at least 3.00 in the last 40 semester (60 quarter) units of completed science and mathematics courses. Students with an overall math and science GPA of at least 2.7 will be considered with a mentorship plan developed with their confirmed faculty thesis advisor. Students who do not meet the minimum required criteria for acceptance are encouraged to take post-baccalaureate courses to bring up their GPA.
Applicants with a bachelor's degree from an accredited university but not in a field of biological sciences may take the GRE Biology Subject Test or the MCAT. A score in the 50th percentile or higher on the GRE Subject Test in Biology or MCAT must be achieved.
International Students must provide official TOEFL scores. A minimum TOEFL iBT score of 90 is required.
Scores from the GRE General Test are NOT required. Applicants do not need to submit GRE General Test scores to Biological Sciences and do not need to complete the GRE section on the Cal State Apply application.
Have earned a grade point average of at least 2.5 on the last degree completed by the candidate or have attained a grade point average of at least 2.5 (A=4.0) in the last 60 semester (90 quarter) units attempted
