The Occupational and Environmental Hygiene, Master of Science program is accredited by the Accreditation Board for Engineering and Technology (ABET) Applied and Natural Science Accreditation Commission (ANSAC) and is designed to prepare students to pass the Certified Industrial Hygienist (CIH) examination administered by the American Board of Industrial Hygiene (ABIH).
All Occupational and Environmental Hygiene, Master of Science core curriculum courses are offered through the Bloomberg School of Public Health, so students will need to follow this academic calendar.
The Bloomberg School of Public Health operates on a term system rather than a semester system. There are 4 numbered terms in the regular academic year as well as a summer institute and a winter intersession. The academic terms are 8 weeks in length and the institutes/intersessions are 2 weeks each. Part-time/Online Occupational and Environmental Hygiene, Master of Science students are required to come to campus for courses that do not translate to an online format (laboratory and field trip-based courses). These courses are held during the summer institute and winter intersession. Students will attend 2 summer institutes and one winter intersession over the course of their degree program.
Students must be employed in the industrial hygiene or safety fields considering that all students are required to complete an independent professional project as part of their degree and in most instances, this is completed at the student’s place of employment.
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.
Applicants whose prior education does not include the prerequisites listed above may still enroll under provisional status, followed by full admission status once they have completed the missing prerequisites. Courses completed at a local community college are acceptable.
- Prior education must include:
- An undergraduate degree from a regionally accredited four-year college or university.
- Successful completion of college-level courses in biology, chemistry, calculus, and physics. Admitted students typically have earned a minimum grade point average of 3.0 on a 4.0 scale (B or above).
- If prior education does not include the prerequisites above, the student must complete them before they can be admitted to the program. Courses completed at a local community college are acceptable.
- 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:
- A graduate degree (master’s or doctoral degree), OR
- Successfully completed the Environmental and Occupational Health, Graduate Certificate and earned at least a ‘B’ in all courses taken for the Certificate.
- Students must be employed in the industrial hygiene or safety fields considering that all students are required to complete an independent professional project as part of their degree and in most instances, this is completed at the student’s place of employment.
Program Requirements
All courses listed below are required for degree completion. Students have up to 5 years to complete the degree requirements. We recommend that students working full time limit their course registration to 1 or 2 courses per term.
The majority of the degree can be completed online, but students are required to come to campus for courses that do not translate to an online format. These courses include a hands-on laboratory course (students learn how to do gas, vapor and particulate sampling, use direct reading instruments, etc.) and a field trip course where students visit industries in the greater Baltimore area (examples are: Domino Sugar, Harley Davidson, Nestles Ice Cream, Vulcan Mine, Ellicott Dredges).
Students who complete the Environmental and Occupational Health, Graduate Certificate, prior to being admitted to the Occupational and Environmental Hygiene, Master of Science degree may apply all core curriculum courses towards the degree if they received a ‘B’ or better in all courses.
Students must maintain minimum academic standards (see below). They are also responsible for the following:
- Academic Ethics Course
- Occupational and Environmental Hygiene, Master of Science Part-time/Online Curriculum (all courses are required)
- Independent Professional Project
- Master’s essay and presentation
Academic Standards
Students must meet minimum academic standards to remain in the MS OEH Program. Failure to meet any of the criteria below is grounds for dismissal from the program.
For satisfactory academic progress, students must:
1. Maintain a minimum of 2.75 cumulative grade point average.
2. Retake a required course in which they receive a grade of ‘D’ or ‘F.’
If a student receives a grade of ‘D’ or ‘F’ twice in the same required course, they may not take the course a third time. If the course is a required course with no other options, the student will be dismissed from the program.
Internship, Culminating Project, Master’s Essay and 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 the advisor (Examples).
Part-time/Online students will perform an Independent Professional Project (IPP) at their place of employment in most instances.
