Biology Graduate Program
Our Mission
The Biology Graduate Program prepares enlightened, responsible, and productive scientists with essential skills, a deep understanding of their discipline, respect for diversity, and the ability to think critically and communicate clearly.
We offer a Master of Science in Biology degree; please note that we do not offer a Ph.D. degree. Our program, which typically requires two years, provides advanced training and expertise in biology through coursework, research, and a strong academic environment.
Our graduates go on to be:
Technicians in research labs
Biomedical researchers in academic, government, and industrial labs
Field biologists in federal, state, local, and tribal agencies
Biologists with environmental and other consulting firms
Educators at K-12 schools and community colleges
Doctorates in the sciences (Ph.D.) and professional fields (e.g., M.D., DVM, and other advanced medical degrees)

Program Outcomes
Our graduate students will:
Design a program of study to enhance their knowledge in their chosen area of specialization and to bolster areas deemed deficient in their undergraduate education.
Formulate an area of interest within biology and demonstrate historic and current knowledge of that area.
Design a research project, which will serve as the basis of the thesis.
Defend and Support the results of their graduate research in the form of a professional level thesis.
Program Requirements
We help students design a course of study, comprising 14 credits of required graduate courses, 16 credits of research (BIOL 595 and BIOL 700), and 15 elective credits (total, 45). Students are mentored through the process of conducting original, independent research by their faculty advisor and thesis committee members. We support two thesis formats: a traditional thesis, and a journal-ready manuscript option.
How To Apply
New students are normally accepted for entry in the fall of our academic year (mid-September). Applications for fall quarter priority admission and assistantships are due by February 1st. Admission is a two-step process. Applicants must first meet the general requirements of the School of Graduate Studies and Research. This includes a bachelor’s degree from an accredited institution, and a minimum GPA of 3.0 (in the last 90 quarter hours or 60 semester hours). If applicable, please also read the School of Graduate Studies and Research information for international students before applying.
All applications go through the School of Graduate Studies and Research.
Applicants must then meet the specific requirements of the Department of Biological Sciences:
- An undergraduate degree in biology or closely related field. Deficiencies in the student’s undergraduate training as determined by the Department of Biological Sciences at the time of admission to the program must be removed without graduate credit during the first year of graduate study.
- A faculty member must be willing to serve as the applicant’s graduate faculty advisor. Prior to completing your application, contact prospective faculty advisors to ask if they are interested in taking new students
Please Note: GRE scores are no longer required by the Department of Biological Sciences.
A complete application to the Department of Biological Sciences will include the following:
- CWU School of Graduate Studies and Research Application (including $75 application fee; waivers are available).
- A Statement of Objectives: The statement is limited to 500 words and serves as a sample of your writing abilities.
Please address the following points within your statement:
- What is your motivation for seeking a graduate degree in Biology and how will a M.S. in Biology help you reach your career goals?
- Describe your research interests in Biology, indicate potential faculty advisor/s, and describe previous research experience and any relevant skills or training.
- Provide an example of how you have shown persistence in overcoming obstacles to reach an academic or career objective you set for yourself.
3. Letters of recommendation (3)
4. Official transcripts
5. Curriculum Vitae (academic resume)
6. English proficiency for international students for whom English is a second language. There are several options available to satisfy the English proficiency requirement.

Funding Your Graduate Program
Many of our graduate students are supported by teaching assistantships, which are normally guaranteed for two years (six quarters), given adequate research progress and satisfactory teaching evaluations. Please note that while some students need more than two years to finish their degree, financial support (through graduate assistantships) is available only during the first two years. Applicants who would like to be considered for a teaching assistantship must complete an assistantship application form (in addition to the application for admissions). Research assistantships and summer stipends are occasionally available on a competitive basis, as are other sources of funds related to specific externally-funded projects.
For information on graduate tuition and fees, assistantships, grants and fellowships, scholarships, financial aid, and student employment, please see the Graduate Student Funding section of CWU's Graduate Studies and Research webpage.
