Learn From a Professional Science Master’s Program

The Master of Environmental Science degree is designated as a national Professional Science Master's (PSM) program based on its combination of hands-on learning experiences, professional skill-building, and interdisciplinary breadth. PSM programs prepare students for science careers in business, government, or nonprofit organizations, where demand for a STEM-trained workforce is increasing.

Work With Real Clients Through a Professional Service Project

Each year, through a Professional Service Project (PSP), M.En. student teams help three clients who have requested assistance in solving environmental problems or improving the sustainability of their organizations. Graduates of the Master of Environmental Science program frequently report that both the PSP experience and its application of problem-solving methodology were critical to their success as professionals.
