About This Program

Earning a master's degree in Occupational and Environmental Hygiene will provide students with 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 will include risk analysis and management, environmental sampling techniques, air pollution, program management, toxicology, epidemiology, biostatistics, and occupational health.

This program is part of the Education and Research Center for Occupational Safety and Health (ERC) which is sponsored by the National Institute for Occupational Safety and Health (NIOSH).

The Master of Science (MS) in Occupational and Environmental Hygiene (OEH) is accredited by the Accreditation Board for Engineering Technology (ABET) Applied and Natural Science Accreditation Commission (ANSAC) and is designed to prepare students to pass the Certified Industrial Hygienist (CIH) examination given by the American Board of Industrial Hygiene (ABIH).

The MS OEH is flexible and can be customized to meet a variety of professional and career goals. Students may enroll in a full-time program or may select the part-time/online program. Both options confer the same degree and students must meet the same academic requirements.

Limited funding is available to support students in the professional MS Program.

Tuition and Funding

Master’s Tuition Scholarship (MTS)

All full-time, second-year students in good academic standing are eligible for a Master’s Tuition Scholarship (MTS) from the Bloomberg School. The MTS provides 75 percent tuition support during the second year of the program. Students must successfully complete all required program courses and accumulate a minimum of 64 credits before the department will recommend the student for the scholarship. This scholarship provides a 75 percent tuition scholarship during this stage of the program. Once the scholarship has been awarded, the student must maintain a full time registration for the entire period of the award.

ERC Awards

Additionally, first-year full time MS-OEH students are eligible for a limited number of partial-tuition awards from The NIOSH Education and Research Center (ERC) to be used toward full-time study. As decided by a committee of faculty members, the awards are offered to selected students based on their prior academic achievements and professional potential. Award decisions are made during the admissions process and communicated to students in their letters of acceptance.

Teaching Assistants

Several departmental courses require teaching assistance. Full time students selected as Teaching Assistants (TAs) gain experience in teaching and receive compensation for their efforts. Open positions will be advertised via email by the department’s Academic Program Administrator before the start of each term.
