Master of Science (MS) in Occupational and Environmental Hygiene

Program Objectives and Outcomes

The Master of Science in Occupational and Environmental Hygiene program at Johns Hopkins University is accredited by the Applied and Natural Science Accreditation Commission of ABET under the General and Industrial Hygiene Program Criteria. 

The MS in Occupational and Environmental Hygiene educational objectives focus on objectives that our graduates are expected to reach within a few years of graduation. The objectives were reviewed and approved by our external advisory committee on 2/18/2022 and are stated as follows:  

 The program in Occupational and Environmental Hygiene educates students to think critically, communicate clearly, and collaborate effectively as they apply the fundamental scientific principles of industrial hygiene to environmental and workplace problems. We emphasize the importance of intellectual growth, professional ethics, and service to society.  

 The OEH program has four Program Educational Objectives. Our graduates will:   

  • Anticipate, recognize, evaluate, and control factors in the workplace and the environment that may cause illness, injury, or impairment 
  • Build a successful career and obtain professional certification using the comprehensive education and training received 
  • Integrate industrial hygiene techniques, biostatistics, epidemiology, management, and environmental health concepts into a broader occupational/environmental health practice 
  • Pursue continuing education in research and professional practice of Occupational and Environmental Health 

General Student Outcomes

Students graduating with an MS in Occupational and Environmental Hygiene will have demonstrated an ability to:  

  1. Identify, formulate, and solve broadly defined technical or scientific problems by applying knowledge of mathematics and science and/or technical topics to areas relevant to the discipline 
  2. Formulate or design a system, process, procedure, or program to meet desired needs
  3. Develop and conduct experiments or test hypotheses, analyze and interpret data and use scientific judgment to draw conclusions
  4. Communicate effectively with a range of audiences
  5. Understand ethical and professional responsibilities and the impact of technical and/or scientific solutions in global, economic, environmental, and societal contexts
  6. Function effectively on teams that establish goals, plan tasks, meet deadlines, and analyze risk and uncertainty

Program Curriculum Elements

The OEH program curriculum elements prepare students to:

a. Understand physiological and/or toxicological interactions of physical, chemical, biological, and ergonomic agents, factors, and /or stressors with the human body
b. Anticipate, recognize, evaluate, and control potentially hazardous agents, conditions, and practices in workplace settings 
c. Apply fundamental exposure assessment techniques (both qualitative and quantitative) in workplace settings 
d. Perform industrial hygiene data interpretation of new and existing data including statistical and epidemiological principles 
e. Apply appropriate business and managerial practices to workplace settings
f. Understand, interpret, and apply occupational and environmental standards and regulations
g. Understand fundamental aspects of safety and environmental health

Students will undertake an appropriate professional experience tailored to the needs of the individual student and complete an Independent Professional Project (IPP) and present the results of the IPP in written form and orally.
