Curriculum for the MS in Occupational and Environmental Hygiene

A master's degree in Occupational and Environmental Hygiene gives students the analytical and technical skills needed to identify and address environmental and/or occupational hazards in the workplace and surrounding community. The course of study includes risk analysis and management, environmental sampling techniques, air pollution, program management, toxicology, epidemiology, biostatistics, and occupational health.

Degree Requirements

  • Academic ethics course
  • 76-credit core curriculum
  • Internship/independent professional project, master’s essay, and oral presentation: The student is expected to assume independent responsibility for a project, the content of which should be based on an occupational or environmental health problem that is pertinent to the educational goals of the student and approved by their adviser.

Admissions Requirements

The GRE is required for this program; it is one of the ABET-mandated minimum requirements for admitted students. The MCAT is acceptable but not preferred. A waiver may be requested if the applicant has:

Prior education must include (1) an undergraduate degree from a regionally accredited four-year college or university, (2) successful completion of college-level courses in biology, chemistry, calculus, and physics.

If prior education does not include the prerequisites above, you must complete them before you can be admitted to the program. Courses completed at a local community college are acceptable.


    Tuition and Funding

    ERC Awards

    MSOEH students are eligible for a limited number of partial-tuition awards from The NIOSH Education and Research Center. Awardeeds are selected by a faculty committee based on prior academic achievements and professional potential. Award decisions are made during the admissions process and communicated to students in their letters of acceptance. These tuition awards are not available to international students.

    Teaching Assistants

    Several departmental courses require teaching assistants. Full-time students selected as teaching assistants get experience in teaching and receive compensation for their efforts. Open positions are communicated by email before the start of each term.
