Environmental and Occupational Health


The certificate program educates and trains students to identify major environmental health issues facing public health professionals today. Courses explore the sources of environmental agents, their distribution in community and work environments, transfer routes to humans and possible health effects; the basic biological mechanisms underlying the association between prior exposure and subsequent development of adverse health effects; and control strategies and interventions.


The certificate is intended for public health professionals (non-degree students) who are currently practicing in environmental or occupational health or other areas of public health and seek formal graduate-level training in environmental and occupational health.  It is also offered to masters and doctoral students currently enrolled in any division or department of The Johns Hopkins University other than the Bloomberg Department of Environmental Health Sciences.  Non-degree students must have at least a baccalaureate degree from an accredited college or university with a strong record of successful academic performance.  

Admissions Process

Applicants should review the How to Apply page for information about eligibility and special instructions.  The certificate program's review committee will review the applications and notify each applicant of their admission decision.

Requirements for Successful Completion

The certificate requires a minimum of 18 term credits.  All required courses must be taken for a letter grade.  Electives may be taken pass/fail and students must earn a minimum grade point average of 2.75 in all certificate coursework.  The certificate program length is flexible, however the certificate must be completed within three years.  

The student should review the section of the website that addresses completion before completing certificate program requirements. The student's transcript will not indicate that the certificate was earned until the Notification of Completion has been submitted and verified by the certificate program and processed by the Registrar.
