Environmental scientists, researchers, and policy experts also have roles to play in resource management, conservation biology, and in climate science and climate monitoring. They can also work to protect and manage forests or other open spaces.
With a PhD you might want to pursue a university teaching position. You may also be interested in working with a professional consulting firm, consulting on engineering design challenges, or leading public interest advocacy initiatives.
Some professionals in the field work at federal agencies, such as the EPA, the US Geological Survey, the National Park Service, and the Department of Forestry.
Many environmental science doctoral programs cover core topics—such as research methodology and design courses—and designate course clusters aligned to specific career-related graduate school concentrations.
Courses in an environmental sciences program will vary by school and program. Most doctoral programs in environmental science, though, require dissertation research or other substantive capstone components.
Admissions requirements for an environmental science doctoral program vary by school and program. Some programs may accept students who have completed a bachelors degree while others will require you to have a masters. The following are common admissions criteria:
When applying to an environmental science doctoral program, it can be helpful to provide evidence of the kind of future work or research you aspire to as well as how it relates to your doctoral studies and research interests.
When exploring environmental science PhD programs, it’s beneficial to make sure the school and program are fully accredited.
Regional accreditation testifies that a school meets acceptable standards for academic quality. The coursework in an accredited graduate school program teaches knowledge and skills that are on par with professional standards in your field.
Regional accreditation can also be a requirement for receiving some forms of financial aid. It can also help ensure that your degree will be honored by other schools and prospective employers. The Council for Higher Education Accreditation (CHEA) provides more information on accreditation.
Getting a PhD in Environmental Sciences will typically require several semesters of advanced coursework, such as in basic and applied sciences. So, even if you work part-time as you learn, you may be one of many students who needs financial assistance in order to stay enrolled and stay focused on learning.
You might qualify for state or federal financial aid, need-based or merit-based scholarships, work study programs, or even employer-based tuition assistance. You can also apply for student loans to help you cover any financial gaps. Loan terms can vary, so it’s strategic to look over any student aid package or loan offering carefully.
If you’re anticipating applying for need-based assistance, you can start by filling out the Free Application for Federal Student Aid (FAFSA).
