Graduate admissions requirements

Thank you for your interest in applying for our graduate degree programs. 

We review applications for our PhD, MS and MPH programs once a year for entry the following fall. Please read more about each of the degree options on our Graduate Degrees page. Prospective graduate students submit their applications online through the UW Graduate School. Please review the minimum admission requirements and the admissions FAQs before starting your online application.

Questions about the online application system? Contact the Graduate School: or 206-685-2630.

Application materials

Note: Applicants for our concurrent degrees for the Master of Public Administration or Master of Urban Planning must submit separate applications to those programs and follow their application deadlines.

Applicants to the MPH in Occupational and Environmental Medicine must first be accepted into the Residency/Fellowship program in Occupational and Environmental Medicine (deadline to apply is October 31). Please refer to the Residency/Fellowship How to apply page.

International applicants: Please review the Graduate School’s international applicant information page.

1) UW application fee

An $85 application fee is required. A limited number of need-based fee waivers are available from the Graduate School. Applicants to concurrent degree programs (MS/MPA, MPH/MPA or MPH/MUP) must submit two separate applications and pay two application fees. If you would like to be considered for more than one DEOHS degree, you only need to submit one application and indicate your interest on the Departmental Supplemental Application.

2) Graduate Record Examination (GRE)

All applicants are required to submit official GRE scores, with the exception of applicants holding MD, DVM, DO or PhD degrees from an accredited US institution. Applicants submit their GRE scores through the Educational Testing Service (ETS). The institution code for the University of Washington is 4854. Competitive applicants usually have GRE scores above the 65th percentile, but the application review is holistic and the complete record of accomplishments will be considered.

3) Three letters of reference

Choose people who are familiar with your academic goals and who can speak to your potential for achieving those goals. You will provide the name and email address of your recommenders in the online application. Your recommenders will then be sent instructions for submitting their letter online. Note that many email accounts filter out messages from computer systems such as these. Encourage your recommenders to monitor their spam inbox as to not miss the instructions for letter submission.

4) Resume or curriculum vitae

A brief description of your professional experience, honors awarded or scholarships, special skills, publications and research presentations.

5) Unofficial transcripts

Unofficial transcripts from all undergraduate and graduate institutions you have attended are required (in PDF format). If you are accepted and enroll, the UW Graduate School will request official transcripts from you when you accept the offer of admission. Your transcripts should show completion or projected completion of the following minimum degree and prerequisite requirements:


Applicants to the PhD, MS, MPH in One Health and MPH in Environmental and Occupational Health should have a bachelor’s degree or higher. Applicants to the MPH in Occupational and Environmental Medicine must have an MD, DO or PhD degree.

Grade point average (GPA)

The UW Graduate School requires a minimum GPA of 3.0 for the last two years (90 credits) of study. Applicants with exceptional strengths in other areas with a GPA below 3.0 may still be considered if their overall application is extremely strong.


Successful applicants will be prepared to take required courses in environmental toxicology and exposure science, which assumes a strong knowledge of the topics described below. An applicant deficient in one or more areas may be required to remedy the deficiency before beginning the program.

For all MS and PhD options:

Biology: One year of biology.
Chemistry: One year of general chemistry and two quarters (one semester) of organic chemistry. One quarter of physical chemistry or quantitative chemistry is desirable.
Mathematics: One quarter of differential and integral calculus. Additional calculus is desirable.
Physics: One year of algebra-based physics, covering mechanics, electromagnetism, oscillatory motion and waves.

For MPH in One Health and MPH in Environmental and Occupational Health:

Biology: Coursework covering basic concepts from general biology, including biodiversity of life forms, ecology, structure and function of biomolecules, cell structure, animal development and physiology.
Chemistry: Coursework covering basic concepts from general and organic chemistry, including chemical nomenclature, chemical reactions, stoichiometry, chemical bonding, organic compounds, functional groups and stereochemistry.
Quantitative analysis: Coursework covering basic concepts from elementary statistics, including data description, study design, screening, estimation hypothesis testing, categorical data analysis and regression.

6) English language proficiency requirement for non-native English speakers

Proficiency in English is required for graduate study at the University of Washington. Therefore, every applicant whose native language is not English, regardless of citizenship, must demonstrate proficiency with the English language. The most common way to fulfill this requirement is to submit official TOEFL scores. The institution code for submitting TOEFL scores to the University of Washington is 4854. Additional ways to fulfill the English language proficiency requirement are outlined on the UW Graduate School website.

7) Ranked faculty list

You will be asked to provide the names of 3 to 5 DEOHS faculty whose research interests you and with whom you would want to complete your graduate work. Before you add faculty to your ranked list, please look at the "mentorship" section of their faculty profile to ensure they are taking on new students for your degree category in fall 2020. On their faculty page, you will find a list of student research projects recently mentored by that faculty member.

8) Academic statement of purpose

Your statement is your voice and your introduction to the Admissions Committee. A well-written goal statement should convey your reasons for pursuing graduate work in environmental and occupational health sciences, your research interests, faculty members who you would like to work with and how this degree fits into your academic and career goals. Review our Student Research page to learn about recent projects DEOHS students have completed as well the faculty who mentored those projects.

9) Personal history statement

Students who have varied cultural experiences and educationally or economically disadvantaged backgrounds contribute to the intellectual and social enrichment of our department. We invite you to discuss cultural and educational opportunities (or lack thereof), social and economic disadvantages you have overcome and the ways in which these experiences have affected your life and education.
