Master of Science

The Environmental Science Graduate Program offers both a traditional master's degree with thesis and a non-thesis option.  This page describes the thesis option offered on our main campus at Stillwater.  Students who plan to work in industry, consulting, or with regulatory agencies (such as EPA, ODEQ, etc.) may consider the Professional Science Master (PSM) program offered at OSU-Tulsa.

The Master of Science degree requires students to complete a 36 credit hour course of study. Students must also complete a program assessment form upon completion of degree and return it to the program coordinator. Core curriculum requirements for MS students include the following courses:

  • ENVR 5303 Issues in Sustainability
  • ENVR 5123 Environmental Problem Analysis
  • Natural or Physical Science (3 hours)
  • Skills Component (3 hours)

Research Options

MS students must complete one of the following research options. All options must have an oral or written presentation of a research proposal and an oral defense of the final product. The ESGP program is an interdisciplinary program, and thus the students’ research efforts are expected to address an environmental problem from multiple perspectives, which may include a social and/or economic perspective.

All of the above options are 36 credit hours. The Thesis option consists of 30 hours of courses and 6 hours of Thesis. The Report option consists of 33 hours of courses and 3 hours of Thesis. The Creative Component option consists of 36 hours of courses. (PSM / Environmental Management students complete an internship under the Creative Component option.)


ESGP offers six different specializations which allows students to customize their program of study to their particular interests:

Environmental Education
Environmental Management
Environmental Policy and Conflict Management
Environmental Sustainability
Environmental Chemistry, Toxicology and Risk Assessment
Water and Watershed Management

Advisory Committee

A masters student advisory committee shall consist of at least three members of the OSU Graduate Faculty. One committee member will serve as the student's advisor. A student's advisor will mentor the student throughout their program of study. The student and the members of their advisory committee should consult regularly to review the progress of the student's work. Students create their Plans of Study with the assistance of their advisor and committee. A student's plan of study must be submitted to the Graduate College and ESGP Program Coordinator prior to the completion of their second semester (excluding summer sessions) of enrollment in the Master's program. Any revision of a student's plan of study must be filed with the Graduate College and ESGP Program Coordinator. For more information about the Plan of Study, see the Graduate College's site.

Transfer of Credits

Transfer of credit will only be considered if it was earned when the student was post-baccalaureate (i.e. after earning a bachelor's degree) at an accredited institution and the applicable course(s) was/were certified as a graduate credit by that institution. All courses used as transfer credit must have a grade of "B" or better. A maximum of nine semester hours of approved transfer credit may be applied towards the graduate degree. None of the aforementioned nine semester hours of approved transfer credit may have been previously applied to an earned graduate degree.
