Occupational and Environmental Hygiene Master’s Degree Program*

Earning a master’s in Occupational and Environmental Hygiene will provide you with the analytical and technical skills needed to identify and address environmental and/or occupational hazards in the workplace and surrounding community. Your course of study will include risk analysis and management, environmental sampling techniques, air pollution, program management, toxicology, epidemiology, biostatistics, and occupational health. Graduates work in consulting firms, private industry, military or governmental organizations.

This ABET-accredited program is designed to prepare you to pass the Certified Industrial Hygienist (CIH) examination given by the American Board of Industrial Hygiene. Offered through our top-ranked Johns Hopkins Bloomberg School of Public Health, you will complete the majority of the program online, however, over the course of your studies you will immerse yourself in two separate hands-on experiences on our East Baltimore campus during the Summer Institute session held in June (two weeks each). A dedicated advisor will support you from start to finish.

*This program requires the GRE and is managed and can be completed part-time, online or full-time through the Johns Hopkins Bloomberg School of Public Health.

At the program’s completion, you will:

  • Complete an Independent Professional Project (IPP), ideally at your place of employment.
