Cleveland State University’s Master of Science degree in Environmental Science is offered by the Department of Biological, Geological, and Environmental Sciences (BGES) as one of three interdisciplinary graduate programs in the Environmental Studies Program. The degree program prepares students for a wide range of professional careers that require knowledge of biology, chemistry, or earth sciences in order to address environmental issues. The program is open to both full-time and part-time students.

The program is administered by the department's graduate faculty, which includes Cleveland State faculty, research scientists at the Lerner Research Institute of the Cleveland Clinic, and several Cleveland State University adjunct faculty members from other local institutions.

The MS degree program, with its research thesis focus, prepares students conceptually and technically for careers in applied or basic research in academic, government, or business settings.
