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 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.Students must also complete a program assessment form upon completion of degree and return it to the program coordinator.  Master's students may choose one of the following research options:

Thesis option

The master’s degree with thesis in Environmental Science is a 30 hour Plan of Study comprised of:
• 12 hours of required core courses (see below)
• 12 hours of elective courses
• 6 hours of thesis
• Thesis defense

Non-thesis option

The master’s degree in Environmental Science with the non-thesis option is a 32 hour Plan of Study comprised of:
• 12 hours of required core courses (see below)
• 18 hours of elective courses
• 2 hours of thesis
• Formal Report presentation

The above options may also include an oral or written presentation of a research proposal (depending on department and Advisory Committee requirements). 

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)

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.
