What is the Environmental Science Professional Science Master’s (PSM) option in Environmental Management?

The PSM is the first of its kind in Oklahoma.  It differs from other ESGP degrees by providing students a springboard to industry-specific job opportunities. 

Why Environmental Management?

Unlike traditional master's degrees, this program emphasizes technical training and the development of in-demand business and leadership skills. Students are able to directly apply their learning in their jobs as they pursue their degrees.

Professional Science Master (PSM)

At OSU-Tulsa, we offer the Professional Science Master Degree Program (PSM) in Environmental Management. This non-thesis degree program has been approved for affiliation as a PSM degree by the Commission on Affiliation of PSM Programs and is the first of its kind in Oklahoma.  The Professional Science Master Degree Program differs from other ESGP degrees by providing students a springboard to industry-specific job opportunities. With its regulatory emphasis, the PSM program places high importance on practical problem solving rather than on research; those who plan to pursue a doctoral (PhD) degree are strongly encouraged to apply for our traditional MS degree which results in a thesis.

In lieu of a thesis, the student completes an internship. This experience equips students with practical, hands-on experience for their careers.


Advisory Committee

The Advisory Committee will consist of at least two departments and least two different graduate faculty groups. Four faculty members are on the committee. The outside committee member is to represent the Dean of the Graduate College and must be a full member of the Graduate Faculty
